Latest Patents
Jiuyuan Fan holds a patent for a "Drilling-slitting-sealing-fracturing device and method for a deep low-permeability gassy coal seam." This device incorporates a drilling control system, a high-pressure water power system, a water pressure grading control system, and a fracturing and sealing control system. The drilling control system is designed to adjust the drilling direction and the water supply pressure of the drill rod. The high-pressure water power system supplies high-pressure water at varying pressures to the device. The water pressure grading control system ensures that the flushing water pressure for drill cuttings remains below 5 MPa, while the slitting pressure is maintained between 25-35 MPa. Additionally, the sealing pressure with a borehole sealing capsule is set between 35-40 MPa, and the pressure for further relief and permeability enhancement of the coal seam is between 40-50 MPa. The fracturing and sealing control system manages borehole sealing and hydrofracturing operations.
