The paper attempts to design and development a new type of hydraulic pump. It is the design of combining the advantages of sucker rod pump and rodless botttom hole pump, without pumping rod,and depends on the hydraulic system on the ground providing the impetus. The paper uses the pump Swabbing Principle to design the main parts of the pump structure and size, analyses and calculates the up down stroke of the piston and the switching process of pump valve, uses the finite element method to analyse the main force summing element and check intensity, and designs a ground hydraulic control system to match it. Considering the need of deep mining, salvage equipment is designed. The design shows that there is feasible and reliable to realize the exploitation underground using the new hydraulic pump. The design idea in this paper enlightens the rodless botttom hole pump production in the future and other similar issues.

本文尝试一种新型液力泵的设计和开发，它的设计思想是结合有杆泵和无杆泵各自的优点，取消抽油杆，依靠地面液压系统提供动力，本文从抽油泵抽汲原理出发，设计了抽油泵主要部件的结构和尺寸，对上下冲程柱塞的运动规律和泵阀启闭过程进行分析和计算，使用有限元法对主要零件进行了受力分析和强度校核，并设计与之配套使用的地面液压控制系统，考虑深井开采的需要，一并设计了打捞装置，为理论上实现了这种新型液力抽油泵井下开采的可行性和可靠性做了一些基础的工作，本文的设计思路对今后无杆泵采油等类似问题的研究做了有益的尝试。

As a new rodless oil production equipment, the ESPCP can be applied in high-viscosity, wax content, sand or gas content well, and radically resolve problems met by sucker rod screw pump applied in heavy oil production such as break of rod , offset-abrasion of rod tube and limit to apply in deep or deviation well .The unit also overcomes the low efficiency of ESP pumping high viscosity oil and especially applied in directional well .

潜油电动螺杆泵作为一种新型的无杆采油设备，可用于高粘度、含腊、含砂、含气原油的开采，从根本上解决了有杆螺杆泵在稠油开采中的抽油杆断脱、杆管偏磨和在深井、斜井中使用受到限制的问题，而且也克服了潜油电动离心泵输送稠油效率低的缺陷，特别适用于定向井的原油开采。
