XJFB防偏磨抽稠泵的研制与现场应用
摘要
在综合分析研究国内外抽油泵及其应用条件的基础上,为了解决有杆泵井杆、管偏磨问题及提高稠油井、高气油比井和大斜度井的泵效的问题,研制了XJFB防偏磨抽稠泵。该泵采用机械阀和双柱塞的结构,使抽油杆柱始终处于拉应力工作状态,不会发生失稳弯曲。该泵具有如下技术特性:防偏磨特性;稠油井、高气油比井、大斜度井适用特性;提高泵效特性;现场可操作性强特性。从杆柱负荷、排量、井况适应性等方面与现场使用的一些特种抽油泵进行了对比分析计算,计算结果表明:在防偏磨方面该泵与防偏磨抽油泵相比,具有降低悬点负荷、作业时能够泄油的特点;在抽稠油方面,该泵与螺杆泵相比,具有可以实现深下和大排量的特点;在抽气方面:与防气泵等配套工具相比,具有有效率高、管柱简单的特点。
XJFB防偏磨抽稠泵现场应用45口井,可对比井有效使用寿命均在一年以上,泵效可以达到70%以上。应用结果表明,该泵成功解决了杆管偏磨井的低成本治理问题,解决了常规稠油井、高气油比井和大斜度井的低成本高效开采问题,应用前景广阔。
On the basis of analyzing and researching domestic and oversea suckingpump and its application condition, for the problem of preventing tubing rodwearingandtheproblem ofhighpumpefficiencyinheavyoil wells andhighGOR wells and large slant wells, XJFB wearing control pump in heavyoil isdeveloped. XJFB pump has the structure of mechanical valves and doubleplunger, the pump make the rod pulling and not bending. The technicalcharacteristics of XJFB pump is wearing control, applying the condition ofheavy oil wells and high GOR and large slant wells, high pump efficiency,good maneuverability. The calculation and analyzing of the pump iscompleted about the rod weight, production rate and the applying condition.The results shows that it has low pendulous point load and easy draining onworkover comparing to other wearing control pump, it has large pump depthand big rate comparing to the screw pump, it has high efficiency and simplestringcomparingtoothergascontrolpump.
There are 45 wells using XJFB wearing control pump, the life span isone year longer, the pump efficiency is 70% more. The application resultsshows that the XJFB pump is success in solving rod tubing wearing and lowinvest high production in heavy oil wells, high GOR wells and large slantwells.
