准噶尔盆地侏罗系储集层特征及影响因素分析

Analysis of Jurassic Reservoir Characteristics and Influential Factors in Zhungeer Basin

通过对侏罗系主力储集层的综合评价,指出不同层位在不同地区表现为不同的储集性能。总体上讲,三工河组储层整体较优,发育II类和III类储层,西山窑组储层较差,发育III类和IV类储层,八道湾组储层最差,发育IV类和V类储层;陆西、中拐地区发育好储集层(I类和II类储层),五彩湾和阜东斜坡地区储集层性能较差(III类和IV类储层),莫北地区储集层性能最差(IV类和V类储层)。

According to the comprehensive evaluation of major Jurassic reservoir beds, the storage features for different horizons at different regions are different. In general, the reservoir beds in Sangonghe Formation are better where reservoir beds II and III are developed, those in Xishanyao Formation are poorer, where reservoir beds III and IV are developed, and those in Badaowan Formation are the poorest, where the reservoir beds IV and V are developed. The reservoir quality in Luxi and Zhongguai area is good, that in Wucaiwan and Fudong slope is poorer, and that in Mobei area is the poorest.
