The Fast Road of Shale Gas Development in China —Reflections on Building a Special Test Areas for NationalShale Gas Development

Da-wei Zhang

《工程管理前沿(英文)》 2015年 第2卷 第4期   页码 364-372 doi: 10.15302/J-FEM-2015062

摘要: China’s shale gas development has had a good start. It is necessary that the developers take advantage of the opportunity to make further efforts to promote shale gas development in China, in particular by rolling out a comprehensive plan on a national level. The author makes a proposal to establish a special shale gas test area in and adjacent to the Sichuan Basin as the most important way to promote the rapid development of shale gas in China. For this purpose, the author analyzes the current situation and problems of shale gas development in China, addresses the necessity and feasibility of establishing a special test area for shale gas development, and draws up the scope of this shale gas special test area of about 450 thousand square kilometers, covering Sichuan, Chongqing, Guizhou, and part of Yunnan, Hunan, Hubei provinces, and proposes the establishment of a shale gas test area in China. This consists of an overall plan, targets, and contents in 10 aspects, along with organization and implementation modes. The shale gas exploration and development in the shale gas zones is promoted vigorously by introducing special policies and innovating exploration, development and utilization model. While at the same time, the shale gas zones of continental facies in the Ordos Basin and marine-terrigenous facies in South Hubei Basin will be established. The experiences of the reform in the shale gas zones will be the good practice for the reform of petroleum organization system.

CO, N, and CO/N mixed gas injection for enhanced shale gas recovery and CO geological storage

《能源前沿(英文)》 2023年 第17卷 第3期   页码 428-445 doi: 10.1007/s11708-023-0865-9

摘要: In this work, using fractured shale cores, isothermal adsorption experiments and core flooding tests were conducted to investigate the performance of injecting different gases to enhance shale gas recovery and CO2 geological storage efficiency under real reservoir conditions. The adsorption process of shale to different gases was in agreement with the extended-Langmuir model, and the adsorption capacity of CO2 was the largest, followed by CH4, and that of N2 was the smallest of the three pure gases. In addition, when the CO2 concentration in the mixed gas exceeded 50%, the adsorption capacity of the mixed gas was greater than that of CH4, and had a strong competitive adsorption effect. For the core flooding tests, pure gas injection showed that the breakthrough time of CO2 was longer than that of N2, and the CH4 recovery factor at the breakthrough time (RCH4) was also higher than that of N2. The RCH4 of CO2 gas injection was approximately 44.09%, while the RCH4 of N2 was only 31.63%. For CO2/N2 mixed gas injection, with the increase of CO2 concentration, the RCH4 increased, and the RCH4 for mixed gas CO2/N2 = 8:2 was close to that of pure CO2, about 40.24%. Moreover, the breakthrough time of N2 in mixed gas was not much different from that when pure N2 was injected, while the breakthrough time of CO2 was prolonged, which indicated that with the increase of N2 concentration in the mixed gas, the breakthrough time of CO2 could be extended. Furthermore, an abnormal surge of N2 concentration in the produced gas was observed after N2 breakthrough. In regards to CO2 storage efficiency (Sstorage-CO2), as the CO2 concentration increased, Sstorage-CO2 also increased. The Sstorage-CO2 of the pure CO2 gas injection was about 35.96%, while for mixed gas CO2/N2 = 8:2, Sstorage-CO2 was about 32.28%.

《能源前沿(英文)》 2019年 第13卷 第2期   页码 354-366 doi: 10.1007/s11708-018-0581-z

摘要: A series of breakthroughs have been made in the understanding, evaluation, and exploration of shale gas from discovery, environmental protection to efficient exploration in the discovering of Fuling Gas Field. By revealing the positive correlation between organic carbon content and siliceous mineral content of shale deposited in deep shelf, dynamic preservation mechanism of “early retention and late deformation,” it is clarified that the shales deposited in deep shelf are the most favorable for shale gas generation, storage and fracturing. The preserving conditions determine the levels of shale gas accumulation, thus the evaluation concept of taking the quality of the shale as the base and the preserving conditions as key is proposed, the evaluation system for strategic selection of favorable zones is established for marine shale gas exploration in Southern China. Moreover, the “sweet point” seismic forecasting technologies for marine shale gas, the “six properties” logging technologies for evaluating shale gas layers, the technologies for quick and efficient drilling of horizontal well groups, and the fracturing technologies for composite fractures for horizontal wells are invented. The paper discussed the exploration prospect of shale gas in the shales of Wufeng-Longmaxi Formation in great depth in Sichuan Basin, shale gas exploration in the outer region of the south, and continental shale gas exploration in China.

《工程管理前沿(英文)》 2015年 第2卷 第1期   页码 76-81 doi: 10.15302/J-FEM-2015011

摘要: The Fuling Marine Shale Deposit contains vast gas resources. Due to tectonic activities, complex surface and geological conditions, significant differences make it unlike that of North America. Thus, it is not suitable to completely copy the technology and the development model from North America. Therefore we need engineering technology and a business development model fit for Fuling Shale Gas Development (FSGD). Through difficulties and characteristics analysis of the shale gas development area, we determined geological engineering design methods and integrated workflow, established a series of the core technologies, including horizontal well drilling with long laterals, staged fracturing and completion technology, developed main fluids, tools and equipment, put forward “well factory” mode in mountain region and “full cycle learning and system optimization” management methods. Break through was made in China’s first large-scale shale gas fields commercial development. By the end of 2014, production capacity reached 25 × 10 m /a, and cumulative gas production reached 12.24 × 10 m , which made a solid foundation to build production capacity of 50 × 10 m /a in 2015 and 100 × 10 m /a in 2017. Not only has FSGD established a demonstration for the other shale gas fields’ development, but also will be taken as reference to other large and extra-large construction projects of the industry.

Engineering Philosophy-based Reflections on Efficient Development of Shale Gas in China

He Liu,Jian-wen Yan,Qing-hai Yang

《工程管理前沿(英文)》 2015年 第2卷 第2期   页码 108-113 doi: 10.15302/J-FEM-2015030

摘要: The Shale Gas Revolution began to have a significant impact on global supply and demand of natural gas; also the price trend of natural gas has been greatly affected. This phenomenon raised concerns among natural gas producers and consumers. China has abundant shale gas resources, but the development scale is small while facing problems including weak exploration and evaluation basis, overlapping royalties, complex terrestrial environment, lack of technical practices and accumulation, inadequate management and regulatory mechanisms, etc. To overcome these challenges for large-scale shale gas development, we believe that shale gas development is not only a single technical problem, but a systematic engineering demanding multidisciplinary research that will be bound to spread to humans, nature, and society. Therefore, to ensure the healthy development of China’s shale gas, it is required to coordinate global and local relationships, engineering and community relations, as well as to break up the conflicts between engineering and nature, engineering and economy, along with engineering and society.

《中国工程科学》 2012年 第14卷 第6期   页码 56-63

摘要:

美国页岩气大多为海相热成因型,产气页岩主要分布在前陆和克拉通盆地的泥盆—石炭系,埋藏深度一般为1 500~3 500 m。我国页岩分为海相、海陆过渡相与煤系、湖相三类,其中海相页岩主要发育在坳拉槽和克拉通盆地的下古生界,富有机质集中段分布稳定,热成熟度偏高,有较高的含气量,勘探前景最好;海陆过渡相与煤系页岩主要发育在大型坳陷和前陆盆地,层系以石炭系—侏罗系为主,没有明显的富有机质集中段,含气量差别较大,勘探潜力有待落实;湖相页岩主要发育在中、新生代陆相盆地,富有机质集中段厚度大,成熟度较高的凹陷中心区可能具有一定资源前景。预测我国页岩气勘探将经历较长的探索期,未来年产量可达500亿~600亿m3规模。

摘要:

影响页岩气规模开发的因素很多,最核心的因素是首先要通过建立地质评价标准,选出页岩气核心区。核心区的确定关系到在页岩气勘探初期,是否能找准页岩气最富集的目标,选择最有利地区进行勘探,突破出气关,进而实现大规模经济开发。从页岩气成藏特征、页岩气富集因素分析入手,重点探讨我国富有机质页岩的丰度、成熟度、脆性矿物含量、含气性以及盖层等关键参数及其作用。借鉴北美页岩气勘探开发和研究成果,结合我国页岩气勘探开发和研究新进展,初步建立我国页岩气核心区地质评价标准,并优选出我国南方海相页岩气的核心区,指出四川盆地南部是我国最现实的页岩气开发区。

摘要:

通过大量地震、钻井、测井、矿物、地球化学、物性资料分析,认为济阳坳陷渤南洼陷古近系沙一段、沙三下和沙四上亚段页岩分布面积广,有机质丰度高,有机质类型以I—II型为主,有机质成熟度分布范围宽,具备形成大量页岩油气的物质基础,三套泥页岩全岩矿物组成中粘土矿物含量低,脆性矿物含量高,以碳酸盐含量为主,利于页岩油气的开采。页岩中压力系数高,各类微孔隙、微裂缝发育,从而容易形成网状的油气储存体系,利于页岩油气的保存。含油、水饱和度分析资料显示,渤南洼陷沙三下亚段12上—13上层组页岩中具有较高的单位岩石含油气量,是页岩油气勘探的有利层段,其中的纹层状泥质灰岩是最有利的岩石类型,具有较好的页岩油气勘探前景。

《中国工程科学》 2012年 第14卷 第6期   页码 101-105

摘要:

中国南方广泛发育下寒武统、下志留统、上二叠统三套海相区域性富有机质泥页岩,同时在四川盆地、江汉盆地和苏北盆地发育陆相富有机质泥页岩,具备形成页岩气的地质条件。但是,与美国页岩气相比,南方海相页岩气具有多期构造运动叠加改造、热演化程度高、保存条件复杂的特点,而陆相泥页岩有机碳含量、孔隙度相对较低,因此南方页岩气勘探面临诸多挑战,不能盲目乐观。笔者等对比研究认为,四川盆地海相、陆相是实现页岩气规模勘探开发的现实领域,江汉盆地、苏北盆地陆相可作为南方页岩气勘探的后备领域。
