蒸汽驱开采是开采稠油的主要方式,游梁式抽油机和有杆泵是目前稠油开采中使用的主要设备。本文基于稠油的粘温特点,以辽河油田某稠油区块为例,分别从地层、设备、工作参数等几方面抽油机井泵效的影响因素进行综合分析,展开相关研究并提出了用于稠油蒸汽开采的抽油机提高泵效的治理对策及需要重视一些问题。
Steam flooding is the main method for producing heavy oil. The beam pumping unit and rod pump are the main equipment used in heavy oil production. Based on the viscous temperature characteristics of heavy oil and taking a heavy oil block in Liaohe Oilfield as an example, this paper analyzes the influencing factors of pumping efficiency of pumping wells from aspects of formation, equipment and working parameters respectively, Heavy oil steam extraction pumping unit to improve pump efficiency and countermeasures need to pay attention to some problems.
