摘要
在前人研究的基础上，对泥岩涂抹作用造成的断层侧向封闭性进行了深入分析。应用Ｌｉｎｄｓａｙ等（１９９３）提出的泥岩涂抹系数及其与断层侧向封闭性之间的定量关系，以松辽盆地三肇凹陷汪家屯气田Ｗ１、Ｗ２、Ｗ３、Ｗ４断层及塔里木盆地轮南地区轮南断层和轮南南断层为例，计算其断开主要目的层盖层段泥岩涂抹系数，对这些断层在主要目的层段处形成的侧向封闭性及其对油气运聚所起的控制作用进行了研究。应用结果表明，泥岩涂抹系数是研究断层侧向封闭性的一个有效指标。
Based on predecessors' researches, this paper deeply analysed the lateral sealing of faults caused by the mudstone daubing.According to the mudstone daubing coefficient put forward by Lindsay (1993) and the quantitative relation between it and the lateral sealing of faults, and taking W1,W2,W3, and W4 fault of Wangjiatun gas field in Sanzhao sag of Songliao basin and Lunnan and southern Lunnan faults in Lunnan area of Tarim basin as examples, this paper analysed the lateral sealing of faults and its role in oil and gas migration and accumulation by calculating the mudstone daubing coefficient of the caprocks of their main target layers. The applied results indicate that the mudstone daubing coefficient is an important index to study the lateral sealing of faults.
