射孔层段优化与压裂工艺相结合技术在准噶尔盆地的应用

准噶尔盆地油藏类型多样,低孔低渗储集层较多,岩性差异大,岩石致密,产层较多但较薄,并且还有顶、底水,试油低产,不经过压裂改造很难形成工业油气流,为了解放这些储集层,采用了优化射孔层段与压裂工艺相结合的方式对储层进行了压裂改造。射孔层段优化和压裂工艺相结合技术不仅使各个薄油层都得到了较好的改造,并且防止了压裂时压窜目的层上、下水层或应力较小的夹层,以免影响压裂效果。

TECHNOLOGY OF PERFORATED ZONE OPTIMIZATION COMBINED WITH THE FRACTURING USED IN THE JUNGGAR BASIN

The reservoir styles and lithologic characters in the Junggar basin are diverse,and it is the reservoir with low porosity and permeability,also it has many thin layers,What is worse,it has underscreen or basal groundwater.But the reservoir can not form the commercial oil and gas flow without fracturing technology.In order to get good results,we use the technology of perforated zone optimization combined with the fracturing,and using this technolog,the various reservoirs can be reconstructed better as far as...
