采用高压喷射钻井技术是提高钻井速度的重要途径,大马力机泵组保证高压循环系统在150大气压下工作不刺不漏也是重要一环。NB_8—600泥浆泵原设计使用的(木向)胶密封件适应不了这个新要求,特别是矩形凡尔盖胶垫,剖分式拉杆盘根和硫化式活塞等密封件,当泵压上升到100大气压以上时,其使用寿命迅速下降,造成班班修泵,增加了井队工人的劳动强度,影响了钻井速度。
The use of high-pressure jet drilling technology is an important way to improve drilling speed, high-power pump to ensure high-pressure circulation system work at 150 atmospheric pressure is also an important part. NB_8-600 Mud pump Original design (wood) plastic seal can not meet this new requirement, especially the rectangular gasket, split rod rod and vulcanized piston and other seals, when the pump pressure rose to 100 above atmospheric pressure, the rapid decline in its service life, resulting in pumping repair classes, increasing the labor intensity of the well team workers, affecting the drilling speed.
