通过国内外的钻井增压技术研究,到目前为止不论是地面增压钻井技术,还是井下增压钻井技术都存在着自身的不足,地面增压对钻井设备要求较高、钻井成本太高,井下增压的动力转换机构比较复杂,而且高压流道的布置也是比较有难度的,工作寿命低、可靠性能差、加工制作也有一定的困难,不断的制约着井下增压技术的向前发展,对于石油钻井的提速的有着较大的限制作用。文章提出了一种新的井下增压提升装置,利用现在应用比较成熟的螺杆钻具作为动力,通过特殊设计简化的螺旋换向机构,最后将螺杆钻具的旋转运动不断的转换为井下柱塞泵的轴向运动,成功的实现了对一部分少数钻井液的加压,从而从超高压喷嘴喷出,辅助钻头破碎岩石。 At home and abroad through the study of drilling booster technology, so far both ground pressure drilling technology, or underground pressure drilling technology has its own deficiencies, ground pressure on the drilling equipment is higher, drilling costs are too high, downhole Turbocharged power conversion mechanism is more complicated, and the arrangement of high-pressure flow channel is also more difficult, low working life, poor reliability, processing and manufacturing have some difficulties, continue to constrain the underground pressure technology forward, for Oil drilling speed has a greater limiting effect. In this paper, a new type of downhole pressure boosting device is proposed. By using the currently used screw drill as a driving force, a specially designed simplified screw reversing mechanism is adopted, and finally the rotary motion of the screw drill is continuously converted into a downhole plunger Pump axial movement, the successful realization of a small number of drilling fluid pressure, which ejected from the high pressure nozzle, aided drill bit broken rock.
