Dual-Comb Ranging Review

Zebin Zhu, Guanhao Wu

Engineering 2018, Volume 4, Issue 6, Pages 772-778 doi: 10.1016/j.eng.2018.10.002

Abstract:

Absolute distance measurement is a fundamental technique in mobile and large-scale dimensional metrology. Dual-comb ranging is emerging as a powerful tool that exploits phase resolution and frequency accuracy for high-precision and fast-rate distance measurement. Using two coherent frequency combs, dual-comb ranging allows time and phase response to be measured rapidly. It breaks through the limitations related to the responsive bandwidth, ambiguity range, and dynamic measurement characteristics of conventional ranging tools. This review introduces dual-comb ranging and summarizes the key techniques for realizing this ranging tool. As optical frequency comb technology progresses, dualcomb ranging shows promise for various professional applications.

Resource evaluation，position and distribution of tight sandstone gas in China

Zhang Guosheng ,Deng Songtao

Strategic Study of CAE 2012, Volume 14, Issue 6, Pages 87-93

Abstract:

Based on the reservoir forming condition research of tight sandstonegas in Ordos Basin, Sichuan Basin and Tarim Basin, the authors give two types of tight sandstone gasreservoirs,sloped lithologic type and structural type which are the main of tight sandstone gas reservoirAnd based on the existed tight sandstone gas reservoir analysis, the authors get the main parametersThe tight sandstone gas is the most realistic source in present.

Exploration status and potential evaluation of tight gas in Sichuan BasinBian Congsheng

Bian Congsheng,Wang Hongjun,Wang Zecheng,Xu Zhaohui

Strategic Study of CAE 2012, Volume 14, Issue 7, Pages 74-80

Abstract:

The majority of discovered reserves is central Sichuan Basin, but the economic development to the reserves is difficult because of the high saturation of water in gas reservoirs. Based on comprehensive study on the gas accumulation conditions, the evaluation to gas resource of Xujiahe formation is done, which points that exploration potential regions are Xu 2 and Xu 4 of Jinhua-Pengxi in central Sichuan Basin, and Xu 3 of Jiange in northwest of basin, where the source rock and reservoir as well as fracture are developed well. High-production gas from lots of wells and discovered scale reserves show that these potential regions will become the important new fields in Xujiahe formation, Sichuan Basin.
