摘要
通过不同层系地层密度测井资料,对上覆岩层破裂压力梯度进行了初步研究,分析了上覆岩层破裂压力梯度变化,提出了适合萨北开发区注水井的破裂压力梯度,对今后水驱注水井破裂压力的计算及确定具有一定的指导意义。
Through the fonnation density logging data in different series of strata, preliminary study on fracture pressure gradient for overriding strata as well as its variation has been carried out, presenting the fracture pressure gradient suitable for injectors in North Saertu development area. The research has certain guidance for the next calculation and determination of fracture pressure gradient of injectors.
