Sinopec News Network reported on June 12 that good news came from the Fuling work area.
The well Jiaoye 31-6HF drilled by the 50143JH team of Jianghan Petroleum Engineering Company Drilling No.
1 Company was successfully completed.
The drilling cycle was 25.
75 days, which broke the previous report by brothers.
The unit set a record for the shortest drilling cycle of 25.
83 days, which is the fifth time the company has rewritten this record since last year, demonstrating the strength of Jianghan's drilling technology
.
Jiaoye 31-6HF well is located in Tanzhong Village, Jiaoshi Town, Fuling District, Chongqing City.
It is a horizontal development well deployed in the lower gas layer of the Longmaxi Formation
.
The shallow gas zone in the block where the well is located is relatively active, and complex downholes such as collapse, collapse, leakage, blowout, and jamming occur from time to time, and there is a high risk of well control and casing collision prevention
In order to ensure the safe and rapid construction of the well and achieve the speed-up goal, the company carefully studied the drilling design and adjacent well data, discussed technical plans many times, and formulated corresponding technical measures
.
The team strictly implemented operating instructions and technical measures, and made preparations in advance when drilling and tripping to reduce the sand content of mud and ensure unobstructed and smooth wellbore
It is reported that the Jiaoye 31 platform has deployed a total of 4 wells.
