| 摘 要： | 柯柯亚地区具有形成致密砂岩气的条件,即有利于形成致密砂岩气藏的异常压力封隔层、良好的气源条件以及特低孔、低渗储层的广覆式分布.由于该区独特的地质条件,在3 000 m附近发育了一套封隔层,形成了上、下2种压力系统,且各系统内的油气地球化学特征不同.致密砂岩气藏上部为正常压力系统,具有边底水构造.下部压力系统内的气藏具有...

| Abstract: | There are good conditions for forming tight sandstone gas in Kekeya area, Tuha Basin, including abnormal pressure sealed formation, good conditions of gas source and wide distribution of extra-low porosity and low permeability reservoirs. Because of the unique geological conditions in this area, it developed a set of sealed formation at the depth of about 3 000 m, formed the upper and lower pressure system, and the geochemical characteristics of petroleum are different. The upper tight sandstone gas reservo... |
