摘要
Abstract
The sucker rod-jet pump lifting system powered by light oil is selected as the best choice for wells in Lungu oilfield to change the condition that the single lift technology can meet the requirement of oilfield development because of the deep wells, heavy oil and poor fluid production ability. In order to reduce the amount of light oil, production fluid and mixture fluid were used as the power fluid of the combination-lifting system, and the proportion model for viscosity & density of system fluid and that of light oil was. According to the coMParison of all kinds of power fluids such as light oil, production fluid, mixture fluid and active water, it finds that the mixture power fluid with light oil 0.5 parts is the best choice. At last, example calculation and field application of combination lifting system with mixture fluid as power fluid are carried out, the results show that the power fluid system not only can maintain the system pump efficiency at a high level, but also can increase the carry ability of per unit volume light oil obviously. All of these can save the light oil resources dramatically.关键词
