  China oil network news as of November 16th, Changqing Oilfield in Ansai, Jingan, Huaqing, Zhen Bei oilfield has completed 116 wells side. Among them, 102 wells have been put into production, and the average oil production per well is 2.28 tons per year in the initial stage of side drilling.

  With the development of oilfield development time, the ratio of long stop and low production wells increases year by year, which seriously affects the stable production of 50 million tons per year in Changqing oilfield. To this end, Changqing Oilfield through the implementation of drilling wells in the dead casing sidetracking Nii eye, to avoid the flooded area to use remaining oil, improve the well pattern sidetrack drilling technology, looking for stable production area.

  Changqing Oilfield Development Department, engineering technology department and Institute of oil and gas technology combined with each oil production plant construction project group, actively carry out sidetracking drilling and completion technology research, and ultimately formed a "MWD+ gravity tool surface" inclined section window technology. At present, the technology has the largest deviation from 37 degrees while sidetracking ability and toughness cement slurry system supporting technology research and development form, improve the cementing quality of sidetracking narrow gap, through the application of casing suspension and top packer completion technology integration, for the latter part of the segmented multi cluster provides good conditions for wellbore fracturing.

  The breakthrough of side drilling technology provides an effective tool for stable production in Changqing oilfield. With the continuous development of sidetracking technology, the drilling cycle of side drilling is shortened from 15 days to 10 days, and the target radius is reduced from 20 meters to 5 meters. The good rate of cementing is increased from 56.5% to 88%, and the cost of single well drilling is reduced by nearly 20%.
