彰武油田主要目的层为九佛堂组,该层位裂缝发育,在钻井及固井过程中普遍存在漏失情况。针对九佛堂组裂缝条件及漏失特点,采用刚性颗粒堵漏材料,段塞式堵漏方法,可以有效增加堵漏的成功率,大幅节约堵漏时间,在现场应用中取得良好实验效果。并且通过承压堵漏的方法,可以增加地层承载力,理论上应能满足固井要求。
The main purpose of Zhangwu Oilfield Jiufotang Formation, the development of cracks in the layer, drilling and cementing process in the ubiquitous loss situation. According to the fracture conditions and leakage characteristics of JFD group, rigid particle plugging material and slug plugging method can effectively increase the success rate of plugging, greatly save plugging time and achieve good experimental results in field application. And through the method of pressure plugging, can increase the bearing capacity of strata, in theory, should be able to meet the cementing requirements.
