准噶尔盆地东部白家海地区油气成藏条件研究
|
摘要
研究区范围南至阜2、阜4井一线，北以滴水泉断裂为界，东以沙西断裂为界，西至彩35井一线，面积约5000Km~2。
本项目以区内多年的勘探成果及研究认识为基础，从含油气系统分析的角度入手，通过对含油气系统的源岩、储盖条件、圈闭条件、匹配关系等方面的分析研究，总结区内不同构造位置、不同层系的成藏规律，建立了研究区油藏的成藏模式。提出以下认识：
①石炭系、二叠系烃源岩为白家海地区油气成藏的主要源岩，油气藏多在紧邻这两套烃源岩的部位形成；
②白家海地区油气主要以“线状”方式运移，即油气主要沿断裂等薄弱带进行垂向或水平运移，顺层以“面状”方式运移的效应对成藏贡献有限，因而区内的油气藏多形成于断裂相对发育的部位；
③研究区区内油源充足，圈源距离和油气运移通道是控制成藏最重要的两个因素。
The research area is ranging from the south of Dishuiqian fault to the north of Bu-2 well and Bu-4 well ,from the east of Cai-35 well to the west of Shaxi fault .It covers about
5000 Km2.
Based on tire exploration fruit and the research knowledge obtained,this topic sums up the reserveir-forming laws in different structural position and different sequence and establishes the reservoir-forming model in this area by analyzing and studying the source rocks ,reservoir-seal conditions ,trap conditions and matched relationship of hydrocarbon-bearing system .And the following knowledge is gived :
1)The Carboniferous and Permian hydrocarbon source rocks are the main source rocks that form hydrocarbon accumulations in Baijiahai area .And the oil-gas accumulations of this area are most formed in the position in which this two source rocks adjoin.
2)The oil and natural gas in Baijiahai area are mainly migrated in the way of line ,i.e the oil and natural gas are mainly migrated along the belt such as fractures in vertical or horizontal direction .However .there is little contribution to form accumulation when oil and gas are migrated along the strata surface in the way of plane .So the hydrocarbon accumulations in this area are most developed in the position that fractures are relatively grown.
3)The research area is rich of oil source .Trap-source distance and hydrocarbon migration pathway are the most two factors that control formation of accumulation .
