SELECTIVE COMPLETION TECHNIQUE FOR HORIZONTAL WELL

In Well Renping 2 of Huabei oil field, the intermediate casing was set to the top of buried hill at 3150. 36 m, then the build up and horizontal sections were drilled with 152. 4 mm bit to 3483 m. A completion string consisted of 3 packers and 2 CMD slide sleeves was used to divide the target interval into two sections. A commingled production test was done with both slide sleeves open by the position switch tool, then only the lower section was tested with the lower slide sleeve closed and an acidizing was applied finally. The prac-tice proved the selective completion technique successful. This paper describes the structure and function of various tools in the selective completion string and presents in detail its appli-cation in Well Renping 2.
