Reasearch On Sucker Rode Pump In Deep Well Production Of Liaohe Olifield

In recent years, with the development and utilization of oil and gas resources in Liaohe oilfield, Liaohe oilfield faces tight resource replacement, difficult production stable and many other difficult issues. Thus, we must find new mining ways and oilfield development process to maintain stable production. As an improved development process,"Deep well pumping"is widely used in the oilfield, therefore, we must study the design theory of deep pumping wells systematically and offer on-site technical support for deep pumping wells.By research, combined with the actual geological and Liaohe oil field production conditions, the optimization design principles for deep-rod pump pumping process and the calculation theoretical methods are obtained; then the improved supporting tools in the process of deep well pumping from the design calculations, material selection to pilot test are analyzed systematically, which provide a theoretical basis and supporting tool selection criteria for Deep pumping in the oilfield. At the same time, using the theory of rod deep pumping, well Lei62 was calculated and the tube and rod pump structure for deep pumping were optimized which improved the development effectiveness. The actual production of Xinglongtai oilfield also indicates that calculation theory this article offered has a great guiding significance for actual production.
