沈丘盆地石油地质特征及勘探思路

沈丘盆地是中、新生代交错叠置盆地，具有地质结构复杂、断块发育、非均质性强、渗透性差别大、含油层系多、原油多源等特点，有一定油气前景，但勘探难度较大，不适用常规的勘探开发程序，下一步勘探应以小型断块油气藏和断块—岩性油气藏为主要类型，采用多学科综合研究、多因素综合考虑、多手段协同作战的综合勘探方法，在综合评价的基础上，优选有利区块实施滚动勘探与开发。

THE PETROLEUM GEOLOGICAL CHARACTERISTICS AND NEW THINKING OF EXPLORATION IN THE SHENQIU BASIN

The Shenqiu basin is a small crossed superimposed basin of Mesozoic and Cenozoic.Its distinguishing features have the complex geological configuration,developed fault block,outstanding anisotropism,large difference of permeability,multiple oil bearing measures,polytopism of crude oil,and so on.This basin has some showing of oil and gas,but the degree of difficulty of exploration is the quite large and the routine exploration and development methods not are suitable.The small fault block oil and gas accumulation and fault block lithology oil and gas accumulation will be the main types in the exploration of next step.To adopt the comprehensive prospecting methods with the synthetic study of multiple subjects,synthetic thinking of multiple factors and fight in coordination of multiple methods,the favorable target area has optimized and the exploration and development will be put into practice in roll based on the overall evaluation.
