Detailed introduction

Model ZDQ hydroscillator improves the effectiveness of bit pressure transmission and frictional resistance between BHA (the pit bottom assembly like drill bit, centering guide, extra-heavy drill rod ( drilling tools) except for ordinary drilling rod in drilling process by the longitudinal vibration generated by itself, especially to improve the drilling pressure transmission with a screw, reduce the frictional resistance, cut down the ordinary drilling sticking accidents, increase the dynamic drilling pressure and improve drilling efficiency in directional drilling process.

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)

Flat Bottom Junk Mill Type MXP

Junk Mill Type MXP can be divided into three kinds: flat-bottom (or concave-bottom) milling shoe, guide milling shoe and cone milling shoe, according to its structure and shape. At the milling surface, the carbide particles are built up by welding, which plays a part of self-milling. It is used to mill the fallen substances, such as tooth wheel, slipdog, fittings for deep-well pump, etc. with the advantages of anti impact and longer service life. SpecificationsModelO.D. mm(in)Connection APIOverall length mm(in)MXP(A)80C-2A3080(3 1/8)2 3/8REG300(11 3/4)MXP(A)89C-2A3089(3 1/2)2 3/8REG500(19 5/8)MXP(A)92C-NC2392(3 5/8)NC23500(19 5/8)MXP(A)102C-210102(4)NC31500(19 5/8)MXP(A)108C-2A10108(4 1/4)NC26500(19 5/8)MXP(A)114C-210114(4 1/2)NC31500(19 5/8)MXP(A)146C-310146(5 3/4)NC38500(19 5/8)MXP(A)159C-310159(6 1/4)NC38500(19 5/8)MXP(A)190C-410190(7 1/2)NC50500(19 5/8)MXP(A)203C-410203(8)NC50500(19 5/8)MXP(A)292C-630292(11 1/2)6 5/8REG500(19 5/8)MXP(A)305C-630305(12)6 5/8REG500(19 5/8)MXP(A)410C-730410(16 1/8)7 5/8REG450(17 5/8)MXP(A)425C-630425(16 3/4)6 5/8REG500(19 5/8)
