阅读说明：本技术 水平井管内螺旋泵均衡提液装置 (Balanced liquid extracting device for spiral pump in horizontal well pipe ) 是由 陈阳 王绍先 张建国 齐志刚 张磊 魏新芳 马明新 于 2020-06-03 设计创作，主要内容包括：本发明涉及一种水平井管内螺旋泵均衡提液装置,主要由油管、过电缆封隔器、电潜泵机组、套管扶正器、电缆、悬挂扶正器、完井筛管、扶正器、驱动电机、防转锚定机构、螺旋泵体、洗井阀和引鞋组成。其中：电潜泵机组为常规电潜泵组件外加一保护套以提高承重负荷；螺旋泵为独立内管工具,下至水平井投产段指定位置,并通过油管连接上部电潜泵,二者共用电力传输和地面控制系统。螺旋泵井下电机驱动螺旋叶轮,将管内液体由下游推挤至上游,既可平衡滤砂管两端生产压差,改善投产段流入剖面均衡性,又具备提液功效,进而达到充分发挥水平井采液优势的目的。(The invention relates to a spiral pump balanced liquid extracting device in a horizontal well pipe, which mainly comprises an oil pipe, a cable-passing packer, an electric submersible pump unit, a casing centralizer, a cable, a suspension centralizer, a well completion sieve pipe, a centralizer, a driving motor, an anti-rotation anchoring mechanism, a spiral pump body, a well washing valve and a guide shoe. Wherein: the electric submersible pump unit is a conventional electric submersible pump component and is additionally provided with a protective sleeve to improve the bearing load; the screw pump is an independent inner pipe tool and is arranged at a designated position of a horizontal well production section, and is connected with an upper electric submersible pump through an oil pipe, and the screw pump and the upper electric submersible pump share a power transmission and ground control system. The motor drives the spiral impeller in the screw pump well, pushes the liquid in the pipe from the downstream to the upstream, can balance the production pressure difference at two ends of the sand filtering pipe, improves the inflow section balance of the production section, has the effect of extracting liquid, and further achieves the purpose of fully playing the advantages of the horizontal well liquid extraction.)
