Tarim Oilfield joint efforts to make sensitive Strata "insensitive"

Page view

  China oil network news January 19th, 1 wells in Tarim Oilfield Guole tree is ready to jump right valve pressure test, 25 wells with ground engineering construction continued to intensify. In 2017, the Tarim Oilfield Halahatang area drilled 10 wells have been drilled successfully, pressure sensitive formation, drilling success rate of 100%, and all obtained industrial oil and gas.

  Halahatang oilfield belongs to ultra deep and complex fractured vuggy carbonate reservoir, in the depth of 6600 meters below the temperature above 150 degrees Celsius, the original formation pressure of 70 to 80 MPa, the reservoir has multiple pore characteristics and heterogeneity of typical strata, narrow pressure window, the same layer often spills in the drilling process, become a bottleneck the safety of drilling speed.

  In order to ensure the smooth drilling pressure sensitive formation, engineering and technical personnel to improve emergency preparedness, emergency disposal specification, refinement of various types of risk contingency plans in advance, Party A and Party B staff with engineering technical disclosure in advance, all signs of abnormal before the underground complex accident in the bud. Aiming at the characteristics of reservoir physical properties of different blocks, tailored protection technology is built. There are any abnormality in the underground, and the engineering and technical personnel of a party and party all joint action to jointly judge the countermeasures and improve the success rate of abnormity control in the underground. In addition, according to the actual situation of the formation, the corresponding special equipment is matched in the drilling, and the well control expert in the well is selected for 24 hours "close to body" protection.
