志丹地区是陕北斜坡带主要的油气富集地区之一。通过对长6油层组的研究发现河道砂体沉积是影响储层的主要因素。因此本文针对长6河道体系的分析以及油藏富集规律的研究,对河道砂体的展布、油藏的富集有了一定的认识,有利于指导下一步井位部署和有利目标优选工作。
The Zhidan area is one of the major oil and gas-rich areas in the northern Shaanxi slope belt. Through the study of Chang 6 oil layer group, it is found that the sedimentation of channel sand body is the main factor affecting the reservoir. Therefore, based on the analysis of Chang 6 channel system and the research on the law of reservoir enrichment, this paper has some knowledge about the distribution of channel sand body and the enrichment of reservoirs, which is helpful to guide the next well location deployment and favorable target selection .
