  Chinese oil network news August 29th, reporters from the Great Wall drilling company was informed by the Su 11-29-33CH side of Changqing Project Department of the company 50689 team construction of the horizontal well drilling well completion, drilling depth is 4473 meters, drilling cycle of 28.62 days, the maximum horizontal displacement of 1204.72 meters, the water level 900 meters long, created 11 Su block of slim hole sidetracking horizontal well is the longest horizontal section of new record.

  According to the characteristics of Su 11 block formation stability, easy leakage, easy broken drill, 50689 teams to take "directional drilling method and composite drilling combined with the frequency and amplitude of short trip changed at any time according to the actual situation of underground, to ensure wellbore flow, reduce pressure phenomenon.

  During the construction, the 50689 teams learned from the successful experiences of the construction of the two horizontal wells drilled by Su 53-23CH and Su 53-27CH in the construction of the project last year, and formulated the construction technical proposal in advance. Optimization of drilling parameters, with well drilling pressure, displacement, speed, optimization of BHA, precise control of well trajectory, the curvature smoothing, at the same time, increase the drilling fluid input, regular cleaning, ensure wellbore cleaning, effectively improve the drilling efficiency.
