GuanDong injection Wells around 4 Wells is more, and the leakage of the injection Wells is difficult, when drilling to the injection layer, there is abnormal high pressure, etc., brings to the drilling of well control hazards.

 

To solve these problems, the company decided to carry it out in 2682 meters to 3880 meters for fine control pressure drilling. The company technical staff pay close attention to inward and outward flow of change, fine point pressure operation, and timely report the abnormal situation, deal with complex situation quickly and to ensure safe drilling.

 

GuanDong 4 Wells in the process of control pressure drilling, meet good oil and gas shows and ignition success. Fine control pressure drilling technique efficiently find and solve the overflow and leakage problems, at the same time eliminate drillingtroubles, increase rate of penetration and reduce non-production time and reduce the risk of well control played a significant role.
