油田注水开发过程中,随着含水率不断的上升,采出井液量增加,注水井无效、低效注水情况增多,使得整个开发系统效率逐渐降低,注水和耗电量逐渐增加。为了缓解这一问题,降低采油成本,从区块基本情况出发,针对本区块地质条件特征采取相应的措施,提出应用周期注水技术,增产增效,节水节电达到节能目的,从而降低成本、提高油田经济效益。 During the development of oilfield waterflooding, with the continuous increase of moisture content, the amount of fluid produced in the well increases, the water injection wells become ineffective, and the situation of inefficient waterflooding increases. As a result, the efficiency of the entire development system is gradually reduced, water injection and power consumption are gradually increased. In order to alleviate this problem and reduce the cost of oil production, starting from the basic situation of the block, taking corresponding measures according to the characteristics of the geological conditions in this block, the paper puts forward the application of periodic water injection technology to increase production efficiency, save energy and save electricity to save energy and reduce costs , Improve the economic benefits of the oilfield.
