松辽盆地北部泰康—西超地区萨尔图油层岩性油气藏预测
|
摘要
大庆油田属于高勘探开发油田,寻找岩性油气藏成了油田增储上产的一个重要途径。根据泰康—西超地区平缓的单斜地质背景,从地质构造特征、烃源岩、沉积特点及油气运移方面分析岩性油气藏的形成条件。区内萨二、三砂组萨一砂组、萨零砂组主要发育砂岩上倾尖灭、地层超覆、砂岩透镜体及复合岩性油气藏,并阐述各类岩性油气藏的形成特征。将沉积微相分布与地震波阻抗反演相结合,预测本区主要岩性油气藏的分布,认为地层超覆岩性油气藏和复合岩性油气藏主要形成于萨二、三砂组,前者主要分布于中西部地区,后者主要分布于阿拉新构造带上,而上倾尖灭、地层超覆、砂岩透镜体岩性油气藏在萨二、三砂组、萨一砂组、萨零砂组都有发育。
Daqing oilfield has been explored in a high degree,so exploring lithology reservoir become a very important way to increase the oilfield reserves.According to Taikang-Xichao area geology setting that is a flat monocline,this thesis studied the petroleum geology condition of forming lithology reservoir based on geology structure character,hydrocarbon source rock,sedimentary character and hydrocarbon migration.In S2+3,S1,S0,upward pinchout,formation onlap,sand lens and combination lithology reservoir are developed,and this study also characterize these different lithology reservoir formation characters.By combining depositional subfacies distribution study and post-seismic impedance inversion study,the main lithology reservoir distribution of this area is predicted,and it is considered that formation onlap lithology reservoir and combination reservoir are mainly developed in S2+3.Onlap lithology reservoir are mainly distributed in the middle and west area,and the combination reservoir is mainly distributed on Alaxin tectonic belt.Upward pinchout,formation onlap,sand lens lithology reservoir are all developed in S2+3,S1,S0.This lithology reservoir study is significant to the future hydrocarbon exploration.
