摘要
电潜螺杆泵采油系统 (ESPCP)是稠油冷采领域的一项新技术 ,它利用井下潜油电机直接驱动螺杆泵举升液体 ,综合了无杆采油系统、井下电机驱动和螺杆泵的优点 ,与有杆泵相比节能可达 30 %～ 6 0 % ,并可突破有杆泵下泵深度 ,可应用于稠油井、出砂井、含气井、斜井和水平井。对避免因出砂导致的泵砂卡、抽油杆断脱、卡杆等现象效果显著。同时 ,ESPCP不会对油层产生激动 ,具有防砂、降低含水的作用。
ESPCP is a new technology about cool-production of heavy crude, the screw pump is driven straightly to raise oil by the submersible electric motor of downhole, which has the advantages of rodless production system motor-driving and screw pump. It may also reduce energy consumption from 30 percent to 60 percent, surpass the depth of rod-pump. It can be used to heavy crude wells, sand wells, gas-bearing wells, angle wells and horizontal wells. It has great effects on sand-blocking pump, rod breaking and rod-blocking which are due to sands in reservoir. At the same time, ESPCP can not motivate the oil ,it can also prevent sand, reduce of the amount of water.
