标准化设计、模块化建设、数字化管理、市场化服务（简称“四化”）是长庆油田公司在苏里格气田开发过程中形成的工程建设模式。该法适应了长庆特低渗透气田的开发建设，促进了苏里格气田的规模经济有效开发。目前，该创新方法已在油田开发建设过程中得到推广和应用。在发展大油田、建设大气田，建设我国重要的能源生产基地的过程中，大力推动“四化”的应用和工程建设创新，可以加快建设进度，提高建设质量，推动长庆油气田快速上产。

Standardized design, modular construction, digitized management and market-driven operation is a project construction mode taking shape during the development of Sulige gas field, which fits in with the development of low permeability gas field in PetroChina Changqing Oilfield Company, and promotes large-scale, economic and effective development of Sulige gas field. The new mode has also been applied and popularized in the oilfield development. During the process of "developing large oilfield, constructing large gas field, and building Chinese major energy resources production base" , the extensive application of the mode and innovations of the project construction will accelerate construction speed and promote construction quality to rapidly increase oil and gas production of PetroChina Changqing Oilfield Company.
