螺杆泵于上世纪30年代诞生于法国,它是一种容积泵,也是一项运行能耗较低且对稠油及出砂井适应性较强的一项采油举升新工艺。经过近多年制造工艺的较快发展,技术配套程度的日趋完善,出现了大排量螺杆泵(GLB1400、GLB2000等),突破了以往螺杆泵排量较小的限制,扩大了螺杆泵的应用范围。这为部分高含水、出砂井的合理提液提供了一种有效的采油方式。 The screw pump, which was born in France in the 1930s, is a positive displacement pump and a new process for oil recovery that operates less energy intensively and is more adaptable to heavy oil and sand wells. After nearly a few years of rapid development of manufacturing process, the degree of technical support is increasingly perfect, there has been a large displacement screw pump (GLB1400, GLB2000, etc.), breaking the previous restrictions on displacement of the screw pump to expand the scope of application of the screw pump . This provides an effective method of oil recovery for the part of high water cut and reasonable extraction of sand wells.
