摘要

中石化松辽盆地南部新登记区块(简称松南新区)分布着20多个有效勘探面积100~300 km2、现今残留厚度小于3000 m的小型断陷,它们具有相似的成盆、成烃、成藏演化过程。彰武断陷油藏类型及分布规律的研究表明,其成藏具有"低熟近源、陡坡控砂、相带控藏、构造富集"特征,进而建立斜坡带、洼陷带、断阶带成藏模式。

Abstract

There are more than twenty small fault depressions in newly registered blocks of SINOPEC in southern part of Songliao Basin, with an effective area of 100~300 km2, and present residual thickness less than 3000 meters. In these depressions, the tectonic evolution history, hydrocarbon generation and petroleum accumulation process are similar. According to the study results on the characteristics of hydrocarbon accumulation in Zhangwu fault depression, it is indicated that the oils were generated from low mature source rocks, and near the source material. The sand body distribution is controlled by steep slope, the reservoir distribution is controlled by sedimentary facies, and hydrocarbon accumulation is controlled by structures. Then, hydrocarbon accumulation models are established for slope belts, depressions and step faulted belt.
