Western drilling to control unconventional well 3D horizontal well

  China oil network news August 10th, reporters learned that the western drilling directional well technology service company to complete the CHHW2116 service technology of horizontal well drilling, directional duration of 16.34 days, compared with the design saves 4.66 days, oblique section and horizontal section average penetration rate is increased by 102.8% and 122.5% respectively design, a horizontal well in block directional mechanical control drilling speed record.

  CHHW2116 well is the Chepaizi oilfield using a 193.7 mm hole experiment of horizontal well, the well completion process by two, only 200 meters of drilling for safety drilling section, while the lower borehole is 2198 meters long. Because the mining layer is shallow, short straight wells, drilling tool of self suspension light weight, in the later period of construction in the horizontal section is likely due to drill wear resistance due to excessive automation difficulties, plus 21 block formation leakage layer are more prone to leakage wells.

  In order to ensure the safety of underground mine and avoid the fault area, the design of trajectory requires 75 degree azimuth operation. Project team for azimuth wells well trajectory optimization, to minimize the whipstocking section in the construction of the dogleg, Mechanical preferred orientation effect, high ROP of PDC bit and screw drill drilling, the trajectory is relatively smooth, lay a good foundation for the construction of horizontal section.

  At the same time, according to the adjacent well leakage horizon, reasonable control and optimization of the formation drilling displacement, as far as possible to reduce the risk of well leakage.
