Sinochem News Network News on August 16, Zhongyuan Petroleum Engineering Drilling Company No.
1 adopted high-pressure water jet rock breaking technology.
During the construction of Shunbei 4-8H well, the average ROP reached 102.
78 m/h, which refreshed the Shunbei block by 444.
5 mm.
The fastest record of drilling speed for large boreholes
.
This technology requires multiple high-pressure pumps to produce high-pressure mud, increase the pressure drop through the water holes of different drill bits, and further increase the pressure when the mud is ejected from the drill bit, and then pre-crush the bottom rock through the high-velocity mud
.
At the same time, it can also prevent part of the cuttings from sticking to the drill bit, clear the bottom hole rock, and prevent the drill bit from being repeatedly broken
The Shunbei 4-8H well is a development well deployed by the Northwest Oilfield Company in the No.
4 fault zone in the second block of the Shunbei Oilfield
.
The 80106 drilling crew responsible for the construction of the well decided to use high-pressure water jet rock breaking technology
"The high-pressure water jet rock breaking technology can greatly increase the mechanical drilling speed, which has been verified in many construction wells
.
In the next step, we will further tap the potential of the high-pressure water jet rock breaking technology to help drilling speed and efficiency
