China Petroleum Network News "FY105X well perforation equipment all out, perforating bullet all launched, 171.5 mm large size open hole perforation perforation first victory."." In October 25th, C3399 logging company Chuanqing team squad reports to the person in charge of production in dynamic working group.
Well FY105X is located in the hinterland of the Taklimakan Desert, the construction difficulty in front of the Kuche block, considering the reservoir temperature of 150 degrees Celsius, the construction pressure of 120 MPa, hole size and other factors, 127 types of perforating gun pressure preferably 140 MPA with ultra high temperature ultra deep penetration perforator.
The perforation depth in the open hole section of the well is 7400 to 7456 meters, the artificial bottom hole is 7458 meters, and the well slope is 49.8 degrees. The impact force formed at the instant of perforation is easy to cause the collapse of the naked eye section.
According to the construction difficulties of perforation logging Igawa construction design and an antidote against the disease, making the operation plan strictly, sent gold operations team C3399 team is responsible for the construction of. The C3399 team received well, strict implementation of standard operating procedures, strict on-site live seal, detonation, detonation, depth positioning in the four mark, workers carry out their duties, orderly.
The perforating initiating, C3399 team uses the rig pump pressure, shear pin after initiation of oil perforation after race Unicom, lifting the square drill pipe and drill pipe, avoid the gun stuck risks, the successful completion of the construction tasks. Igawa logging site command said excitedly: "this work created a large size openhole perforating depth construction records, accumulated experience for similar engineering complex perforation."
