在深入分析断层垂向封闭机理及其影响因素的基础上 ,提出了断层垂向封闭形成有利深度的概念 ,并建立了利用作用于断裂带正压力与泥岩弹性极限和强度极限相等来确定形成断层垂向封闭上、下限深度的方法 .将此方法应用于松辽盆地汪家屯气田一些重要断层垂向封闭性的研究 ,结果与实际情况相吻合
Based on the deep analysis of vertical sealing mechanism and its influencing factors, the concept of favorable depth for vertical sealing of faults is proposed and a method of determining the fault formation by using the positive pressure and mudstone elastic limit and strength limit is established Vertical closure of the upper and lower depth of the method.Application of this method in the Wangjiatun gas field in Songliao Basin, a number of important vertical sealing study, the results are consistent with the actual situation
