普光气田是一个受构造—岩性控制的高含H2S、含CO2,埋藏深、多压力系统的“三高”酸性气田。探明含气面积45.58Km2,地质储量2813.80×108m3。采用衰竭式开采,一套开发层系,不规则井网,丛式井组布井方式部署开发井。在构造边缘区域部署实施了超深水平井钻井工程。结合超深水平井录井技术的难点,有针对性的提出了技术改进,确保实现了普光气田主体6口超深水平井的安全施工和取全取准各项录井资料,达到钻井地质目的。
The Puguang Gas Field is a “three high” acid gas field controlled by tectono-lithology with high content of H2S, CO2, buried deep and multi-pressure systems. Proved gas area of 45.58Km2, geological reserves of 2813.80 × 108m3. The use of depletion mining, a set of development strata, irregular well pattern, cluster well group deployment well development wells. Depth ultra-deep horizontal well drilling project was deployed in the tectonic margin area. Combined with the difficulty of ultra-deep horizontal well logging technology, the paper puts forward some technical improvements targeted to ensure the safe construction of 6 ultra-deep horizontal wells in the main body of Puguang Gasfield and to obtain all the well logging data to achieve the purpose of drilling geology.
