Sinopec News Network reported on June 29 that the 50840HB drilling team of the North China Petroleum Engineering Company West Section Company successfully lowered the liner of the J30-4-P11 well which was drilled in the northern part of Hubei Province
.
It marked the first horizontal section of the North China Oil and Gas Branch with a "twist-increased-twist" bow-shaped non-guide hole horizontal well, which successfully completed the drilling task
Well J30-4-P11 is the first bow-shaped barrier well deployed by the North China Oil and Gas Branch in the 30 well block of the Dongsheng Gas Field in the northern part of the province
.
In order to reduce the investment cost, the well and the completed J30-4-15 well are located in the same well site, and the center distance between the two wells is only 5.
After undertaking the drilling and construction task of J30-4-P11 well, the 50840HB drilling team of the Western Part Company organized the backbone of production technology, strengthened the analysis of the current well data, optimized the drilling parameters, optimized the drilling tool assembly, and fine-tuned the mud performance, which effectively realized the protection of the reservoir Requirements and optimization of the three-open well trajectory
.
During the drilling operation, the 50840HB drilling team aimed at the horizontal section of the three-dimensional well construction.
The drilling tool and the borehole wall have large friction, many twisting directions, difficult to carry cuttings, and drilling encounters mudstone, which are prone to sticking or falling blocks and sticking.
They use a salt cement slurry system to ensure that the directional drilling parameters are carried out accurately according to the design; strengthen the communication and coordination with the drill bit manufacturer, customize the personalized drill bit suitable for the formation, and realize the single drill bit to complete the horizontal well section drilling construction, and the drilling design in 40.
92 days The cycle was shortened by 2.
08 days, and the drilling construction task was successfully completed
.
At the same time, the 50840HB drilling team also used cementing sliding sleeve technology for the first time, successfully lowering the completion string to the predetermined depth, and successfully completed the drilling task
.
A useful attempt was made for Party A's next engineering design
