东濮凹陷西洼南部1000km2，过去认为生烃岩薄，埋深大，石油地质条件较差，根据对豫深1井等地质资料的再分析、地震资料重新处理和解释，提出了该地区深部存在着巨厚的沙三－沙四生烃岩系，又是沙一段沉积中心等新认识，认为西洼南部油气资源丰富，是东濮凹陷潜力最大的勘探接替地区。认为应予立体评价并指出了具体钻探目标。
According to the reanalysis of the geological data such as the Yu-Shen-1 well and the re-processing and interpretation of the seismic data, it was proposed that the deep part of the area There is a new understanding of the Shasan-Shasi generating hydrocarbon rock series and the sedimentary center of Shahejiechuan that the oil and gas resources in the southern part of Xiwa are abundant. It is the most potential exploration succession area in Dongpu Sag. We think that we should give a three-dimensional evaluation and indicate the specific drilling target.
