摘要
针对海拉尔盆地地应力无遮挡储层的特点 ,压裂时用估算井底净压力的办法 ,根据压裂施工曲线泵压动态变化情况 ,及时调整施工排量 ,探索出一套包括变排量、变砂比等工序在内的系统合理的设计施工方法 ,从而保证井底具有一定的净压力及动态缝宽 ,满足设计加砂需求 ,提高了施工井的一次成功率 。
To the feature of bore reservoir in Hailaer basin,using approximat ing down hole pressure in fracture,according to the dynamic change of pump at operation to adj ust output volume on time the paper develops a set of reasonable method,includin g the sequence of variable output,variable sand ratio,so as to keep the down hol e having a number of net pressure and dynamic fracture.All that can the need of the design of adding sand,raise the successful rate in operating wells and provi de a useful experience for the new district to perform increasing volume and dev eloping.abstract
