池46区块是油房庄作业区的主要生产区块,该区块采油方式均为有杆泵抽吸采油,2011年该区块平均机采系统效率为20.6%,低于国内平均水平。本文主要从有杆泵抽吸过程中能量损耗来分析抽油机系统效率的影响因素,并探讨提高池46区块机采系统效率的有效措施。 Block 46 is the main production block in the Oilfield Zhuang operation area. The oil recovery methods in this block are all sucker-rod pumps. In 2011, the average machine-building system efficiency of the block was 20.6%, lower than the national average. In this paper, the main factors that affect the efficiency of the pumping unit are analyzed from the energy loss of the sucker rod pump, and the effective measures to improve the efficiency of the pumping system in the 46 block are discussed.
