自2012年以来,塔河油田采油二厂液压反馈式抽稠泵泵漏失井次呈快速上升趋势,对采油厂生产造成较大影响。通过对泵漏失井的生产特征、漏失部位特征进行分析,认为抽稠泵漏失的主要原因:一是高含水、高含硫化氢、高矿化度等工况条件等客观条件加速泵漏失;二是泵结构参数不合理引起的泵阀漏失,其中56/38泵、70/44泵因结构限制导致进油阀直径偏小是泵漏失的最主要原因。综合分析认为,通过改进液压反馈泵进油阀结构、增大进油阀和进油阀座尺寸、改进阀球座材质可以有效降低泵漏失几率。

Hydraulic feedback pumps for heavy oil leaked frequently in the production of the No.2 Oil Production Plant ever since 2012, which reduced production. The production characteristics of pump leaking wells and the features of leaking positions showed that there were two major reasons for the leakage:(1) High water cut, hydrogen sulfide existence and high salinity speeded pump leakage. (2) Unreasonable structural parameters. For example, pumps 56/38 and 70/44 leaked due to small suction valve diameter. We can solve this problem by improving inlet valve structure, enlarging inlet valve and seat sizes, and improving valve seat material.
