在肇州油田扶杨油层的构造特征,沉积特征研究基础之上,综合运用岩心、录井、测井及分析资料,通过对单井沉积相、已知探井的油气显示情况及试油结果进行分析,总结了扶杨油层的成藏影响因素和油气富集的规律,指出已发现的油气主要富集在垒堑带和复杂断裂带等有利构造区及厚度大、粒度大、分布稳定的分流河道中。研究结果为三肇凹陷扶杨油层油气富集区及有利勘探目标的预测提供了可靠的依据,满足了油田开发和生产的需求。
Based on the study of the tectonic characteristics and sedimentary characteristics of the Fuyang oil layer in Zhaozhou Oilfield, the core, logging, well logging and analysis data are comprehensively used. Through the analysis of the single well sedimentary facies, the hydrocarbon discovery of the known exploration wells and the oil test results The influencing factors of hydrocarbon accumulation in Fuyang oil layer and the law of oil and gas accumulation are summarized and analyzed. It is pointed out that the discovered oil and gas are mainly enriched in the favorable tectonic zones such as basement and complex fault zones, and have the advantages of large thickness, large particle size and stable distribution In the river. The results provide a reliable basis for the prediction of oil and gas enrichment areas and favorable exploration targets in the Fuyang oil layer of the Sanzhao depression and meet the demand of oilfield development and production.
