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。

本文是对系统的软件设计的相关成果的一个总结。

Summing up these results, we think that the Yinmawanshan batholith came from the mixing, the fractional crystallization and the crust contamination of the enriched lithospheric mantle and the low crust magma.3、the time relationship between the Yinmawanshan batholith' formation and the tectonic extension The field observation and petrology have clearly showed that the Yinmawanshan batholith intruded in the forming period of the Liaonan metamorphic core complex, so this provided direct geological evidence to the viewpoint that the early Cretaceous magamatism of the eastern China developed in the extensionally tectonic setting.

还有一个证据来自对A型花岗岩的研究。A型花岗岩的年代学研究结果显示在东北的大兴安岭地区、张广才岭地区、本文研究区的辽东半岛，几乎所有的上述A型花岗岩都是在120-130 Ma期间形成的，与本文研究的饮马湾山I型花岗岩同时。地球化学资料还显示，这些花岗岩基本具有A1型非造山花岗岩的特点，充分反映了我国东部早白垩世的地质演化与伸展体制有关。根据上述资料我们推测，辽东半岛南部饮马湾山岩体形成时的我国东部由于受岩石圈减薄作用影响而使全区处于伸展构造体制。
