螺杆泵闭环智能采油系统在油田生产中的应用
|
摘要
针对传统螺杆泵存在的地面驱动螺杆泵时,转速瞬间提高,抽油杆产生很大的惯性扭矩,导致抽油杆承受的扭矩大于额定扭矩,抽油杆易拧断;螺杆泵停机时,抽油杆的载荷扭矩瞬间释放,抽油杆快速倒转,容易造成抽油杆脱扣等问题,提出了应用螺杆泵闭环智能采油系统解决上述问题的方案,介绍了螺杆泵闭环智能采油系统的适用条件、工作原理、系统组成、特点,以及现场应用情况,并对实施效果进行了分析评价。实践证明,螺杆泵闭环智能采油系统是一种先进的低成本油井开发生产工艺技术,具有很好的油田生产现场适应能力和较高的性价比。对5口采用游梁式抽油机举升方式且油井地层供液相对不足的油井,实施螺杆泵闭环智能采油系统节能技术改造,改造后其综合节电率达到48.9%,年节电量达209 875 k Wh,单井平均日节电达到115 k Wh。此系统的应用对推进智能化油田建设具有促进作用。
In view of the existing traditional screw pump ground drive screw pump, improve the speed of an instant, sucker rod pumping caused great inertia torque, torque rod bearing is greater than the rated torque, the sucker rod is easy to break; screw pump shutdown, the load torque of sucker rod moment release, the sucker rod reverse, easy to cause the problem of sucker rod tripping, put forward the solution of screw pump closed-loop intelligent production system, introduces the applicable conditions, working principle, system of screw pump oil production system, closed loop intelligent characteristics and field application, and Research on the analysis and evaluation of implementation effect. Practice has proved that the closed-loop intelligent oil screw pump system is an advanced low cost drilling production technology, oil production site has good adaptability and high price, in 5 the beam pumping unit and lift oil well formation liquid supply the relative lack of screw pump oil production system to implement closed-loop intelligent energy saving technology transformation of wells, the comprehensive energy saving rate of 48.9%, single well daily average reached 115 k W, 5 wells annual consumption amounted to 209 875 k Wh. Its application will promote the construction of intelligent oil field, and has broad prospects for popularization and application.
