摘要
螺杆泵抽油是近些年发展起来的一种先进的采油工艺技术,因其系统设备尺寸小、维护和管理方便、系统效率高等优点,受到了人们的日益关注,并在油田上逐步得到广泛的推广和使用。本文概括性地介绍了螺杆泵采油现状、发展趋势、螺杆泵的采油原理。研究了螺杆泵采油系统工况诊断技术,了解泵的工况主要是利用生产数据算井筒和泵的工作特性参数,如扭矩、排量、扬程、效率及功率;并与泵的特性曲线作较,了解泵的工作状况;或者根据扭矩间的比较、电流间的比较了解泵的工作状况,判断与油层匹配状况和泵的工况,分析泵工况较差的原因。
结合先前的设计经验,本文对大排量LB1600螺杆泵采油系统进行了设计计算。对定子、转子部分结构参数就行了优选,使系统趋于更加合理。计算了驱动装置的关键参数,评估了驱动装置的寿命。对螺杆泵采油系统的其它配套设施进行了强度校核,以确保采油系统的可靠性。
现场的实际应用情况说明,LB1600大排量螺杆泵采油系统与95泵、电泵相比,排量降低有限,节电效果明显。与抽油机相比,一次性投入少得多,经济效益可观。列举了近两年LB1600螺杆泵替代同类产品的数据,与国内同类产品相比,LB1600螺杆泵采油系统优势明显。
Oil production by screw pump is an advanced oil production technology developed in recent years, because of its small system size, convenient maintenance and administration and high pump efficiency, so it is taken into account increasingly, and is widely developed and applied in oil fields. The current status of screw pump production, development tendency and producing principle of screw pump are summarily introduced in the thesis. The screw pump system condition diagnosis techniques were studied. Knowing the condition of the pump mainly use of production data to calculate the operating characteristic parameters of shaft and pump, such as torque, displacement, lift, efficiency and power. Comparing with the pump characteristic curve to know the work of pumping conditions. Based on the comparing with the torque, current to know pump operating status, the judgment of pump matching with reservoir conditions and pump operating conditions has been done and the causes of poor pump working conditions has been analyzed.
In this paper, LB1600 screw pump system has been designed and calculated combination of the previous design experience. The stator and rotor parts of structural parameters has been optimized in order to allow the system to become more reasonable. The key parameters of drive device has been calculated and the life span of the drive unit has been assessed. Screw pump system on the other supporting facilities have been conducted the strength checking to ensure that the oil production system reliability.
The practical application of LB1600 large displacement screw pump systems showed that the displacement reducing are limited and energy-saving are effect compared with 95 pumps. Compared with the unit, disposable inputs are much less and economic benefits are considerable. In the past two years, the screw LB1600 alternative similar products data have been cited. Compared with the domestic similar products, LB1600 screw pump systems have obvious advantages.
