套压是影响油井生产运行效果的重要因素,油井套压高低影响回压,回压高低影响产液、含水,利用“负压控套”装置可在有效降低抽油机井套压的同时,实现产油增加、含水降低、吨油耗电下降,综合经济效益明显。 Hedging is an important factor affecting the operation effect of oil well production. The high and low pressure in the well affect the back pressure and the back pressure affects the production fluid and water content. The “negative pressure control set” device can effectively reduce the casing pressure of the pumping well , To achieve an increase in oil production, water cut, tons of oil consumption decreased, the overall economic benefits significantly.
