Two-action Drill Accelerator Type SZJQ

Two-action Drill Accelerator Type SZJQ can be stored energy by hydraulic spring. It should  be applied with  Hydraulic Drilling Jar jointly. The drill collar and Hydraulic Jar (below the Drill Accelerator ) can function an accelerated effect when jarring operates as for making the stuck point gain more jarring force. Meanwhile, it can decrease the damage of tremor produced by up-down jarring for drill tools above Drill Accelerator.   Specifications 型号 Model 外径 O.D. mm(in) 水眼 I.D. mm(in) 接头螺纹Connection  API 最大上击行程 Max. Up-jarring Stroke   mm(in) 最大下击行程 Max. Down-jarring Stroke   mm(in) 水眼压力 Hole Seal Pressure  Mpa(psi) 许用拉力 Max Working Load  kN(lbf) 屈服拉力 Yield Tension   kN(lbf) 许用扭矩 Max Torque  kN﹒m(lbf·ft) 屈服扭矩 Yield Torque   kN﹒m(lbf·ft) 总长  Length   mm(in) SZJQ95 95 (3 3/4) 32 (1 1/4) NC26 178 (7) 178 (7) 35 (5000) 600 (135000) 800 (180000) 4 (3000) 40 (29500) 6651 (261 7/8) SZJQ121 121 (4 3/4) 50 (2) NC38 178 (7) 178 (7) 1100 (247000) 1560 (350000) 15 (11000) 27 (20000) 7185 (282 ¾) SZJQ165 165 (6 1/2) 57 (2 1/4) NC50 165 (6 1/2) 165 (6 1/2) 2000 (450000) 3750 (700000) 25 (18400) 75 (55300) 7476 (294 3/8) SZJQ197 197 (7 3/4) 70 (2 3/4) 6 5/8REG 203 (8) 203 (8) 2600 (585000) 4000 (900000) 30 (22100) 100 (73700) 8000 (315) SZJQ203 203 (8) 70 (2 3/4)    6 5/8REG 203 (8) 203 (8) 2600 (585000) 4000 (900000) 30 (22100) 100 (73700) 8000 (315) SZJQ241 241 (9 1/2) 76 (3) 7 5/8REG 254 (10) 254 (10) 3500 (787000) 5800 (1300000) 40 (29500) 180 (133000) 7259 (285 ¾)

Hydraulic Hole Opener type KY

KY type hydraulic Hole Opener is a new type of hydraulic variable diameter hole opener for drilling or workover operations. It is operated by controlling the mud pump switch at the wellhead to adjust the hydraulic pressure drop in the drill string and realize the opening and withdrawal of the blade. In other words, when the pump is opened, the pump pressure is used to push the piston to overcome the spring thrust upward and drive the blade to slide upward and open in the chute of the housing. When the pump is stopped or the drill tool is lifted up, under the action of spring thrust and wall friction, the blade of the tool moves down in the chute of the housing and withdraw to achieve the purpose of diameter change and reaming, so as to prevent the resistance or stuck when pulling out or tripping in. It has the advantages of reasonable structure, good wear resistance, adjustable reaming size, and can be used for hole enlargement, especially while drilling, realizing the process of "drilling and hole opening in one trip". SpecificationsModelBody ODmm/inFish Neck ODat both endsmm/inConnection（API）Hole Opening Rangemm/inOverall LengthmmRecommendedOperation PressureMPa/ PsiKY234-165234/9.25165.1/6.5NC50260-299(10.25-11.75)39704.55-5.6（650-800）KY295-210295/11.625210/8.256 5/8REG330-381(13-15)5290

Gao Feng's "Top Drive Protector" Successfully Fills Domestic Blank on Trial

Gao Feng's "Top Drive Protector" Successfully Fills Domestic Blank on Trial

Recently, the "top drive protector" independently developed by Gaofeng Company has been tested in a shale gas exploration project in Yunnan, marking another breakthrough in the field of drilling technology in my country. During this trial, the "top drive protector" had no leakage and no significant signs of wear, perfectly fitting the design expectations, and the drilling test was successful, demonstrating the strong strength of Gaofeng Company in the research and development of high-end drilling equipment. It is worth mentioning that under the harsh conditions of the air hammer drill bit struggling to break the rock, the protector effectively responded to the strong vibration caused by the deep rock crushing, formed a solid protective barrier for the top drive and the upper equipment, and significantly reduced the potential damage of the drill string vibration to the key equipment during the shallow drilling stage. This breakthrough design not only ensures the safety and stability of drilling operations, but also greatly improves the drilling efficiency and speed of the air hammer in the super-hard Emeishan basalt formation, injecting strong power into the efficient progress of the project. The successful test of "top drive protector" not only fills the gap in the field of technology in China, but also indicates that China's underbalanced drilling technology is moving towards a new stage of development, a safer, easier to operate and widely applicable future. The successful test of this product not only consolidates the leading position of Gaofeng Company in the industry, but also promotes the company to play a more important role in the technological progress of domestic oil and gas exploration and development and the enhancement of international competitiveness.
