本文根据松辽盆地地质资料，分析了深凹陷中泥岩异常高压带油气生成和初次运移特征，认为泥岩压实和油气生成过程中大量微裂缝的产生和轻质原油呈油相干酪根网络运移，同样是泥岩裂缝油气藏形成的控制因素。
Based on the geological data of Songliao Basin, the characteristics of hydrocarbon generation and primary migration in mudstone anomalous high pressure zone in deep sag are analyzed. It is considered that the formation of a large number of micro-fractures in mudstone compaction and hydrocarbon generation and the occurrence of light kerogen in kerogen network The same is the controlling factor for the formation of shale fracture reservoirs.
