| 目前海外X区块油砂采用高温电潜泵进行开采,存在设备昂贵、检泵费用高等问题,降低了油砂开采的经济效益,因此研究在X区块采用皮带抽油机开采油砂。X区块油砂产量较高,初期单井产量最高可达900m3/d；狗腿度较高,达8~12°/30m；井口斜度较大,最高可达45°,皮带抽油机并不能满足举升液量和斜井口举升需求。针对上述问题,采用前期使用电潜泵后期转皮带抽油机的方式解决产量高的问题,此种开采模式对地面工程设备的转换影响较小；设计抽油机的辅助支撑和皮带导轨解决井口斜度大的问题。通过计算,X区块采用电潜泵转皮带抽油机开采比开采全过程使用电潜泵节省投资1980万元,具有较高的经济效益。 |
| 英文摘要: |
| At present, the X block oil sand is produced by high temperature electric submersible pumps. There are some problems such as expensive equipment and high pump checking cost, which reduces the economic benefits of oil sand producing. Therefore, it is studied to use the belt pumping unit to product oil sands in block X. The liquid production of block X is relatively high, up to 900m<sup>3</sup>/d; the dog"s leg is high, reaching 8~12°/30m; the wellhead slope is large, up to 45°, the belt pumping unit can"t meet the lifting liquid and inclined wellhead lifting demand. In view of the above problems, the problem of high liquid production is solved by using electric submersible pump in the early stage and belt pumping unit in the late stage. This product mode has less influence on the conversion of the ground engineering equipment; the auxiliary support of the pumping unit and the belt guide are designed to solve the problem of large well inclination. Through calculation, the X block uses belt pumping unit in the late stage can save an investment of 19.8 million RMB compared with the whole process uses electric submersible pump, which has high economic benefits. |
