Research and Application on Slim-Hole Oil Recovery Technique in Block-LP of SINOPEC

Xiaolong Li, Wen Xiao, Bing Wang, Liping Zhou, and Huaru Xu
Abstract—Slim-hole oil recovery technique is increasingly used in SINOPEC and there are over 220 slim-hole wells in block-LP at the moment. Meanwhile the dimension of slim-hole brings several problems such as matching tools, eccentric wearing, lifting, separate layer recovery and so on. Through lab experiments and field application test analysis from block-LP, a mature and effective supporting technology for slim-hole well has already been summarized. Also special dimension corollary equipment is under research and development to meet the need of Slim-hole oil recovery technique, such as connecting tripping device, oil drain device, QSA packer, etc. All these special dimension devices are reliable and have been put into use and running well. All in all, through practice slim-hole oil recovery technique is cost savings in both exploration and exploitation, especially in reducing the usage of steel products. The integration of slim-hole oil recovery technique, matching process and separate layer recovery technic will provide certain guiding significance for construction site.

Index Terms—Slim-hole, matching process, corollary equipment, separate layer recovery technic.
