Recently, the Xinchun Company Pai 609-Ping 2 well, supported by the Drilling Technology Research Institute of Shengli Petroleum Engineering Company, was successfully completed, setting the record of the shallowest vertical depth of the horizontal well in the west of Shengli, and successfully exploring the horizontal well screen for heavy oil.
The experience of tube completion steam flooding has laid a solid foundation for the subsequent development of Block Pai 609
.
Well Pai 609-Ping 2 is a pilot test well deployed by Xinchun Petroleum Company in Block Pai 609 of Chunfeng Oilfield, which was drilled by the 30 teams of the Xinjiang Project Department of Shengli Engineering Downhole Operation Company
.
Block Pai 609 is a heavy oil and is planned to be developed by steam flooding with horizontal well screen completion.
The Shengli Engineering Drilling Institute was anxious for the first party.
Aiming at the main construction difficulties of the well, such as the shallow deflection point, shallow reservoir depth, large strata change and abnormal deflection rate, and thin high-quality reservoirs, the simulation analysis and process optimization were carried out, combined with the past vehicles.
Experiencing the construction of super shallow horizontal wells in the sub-work area, carefully drafting the construction plan
.
The plan uses conventional truck-mounted drilling rigs, optimizes the well depth structure, customizes the large-curved special structure screw, selects geo-steering tools suitable for high dog legs, optimizes the drilling fluid performance, optimizes the completion string structure and other measures to achieve low-cost horizontal well drilling and completion Ways to develop ultra-shallow heavy oil reservoirs in this block
During the construction process, the technicians of Shengli Engineering Drilling Institute actively communicated and cooperated closely with the 30 team of the Xinjiang Project Department of the Xinjiang Project Department of Shengli Engineering Downhole Operation Company, and used small displacement and large camber screws to build the angle of one-opening and two-opening.
