随着油田开发技术水平的提高以及开发过程的不断精细化,分层注水作为油田注水的主要方式,受到了相关生产部门的极大重视。同时,与之相关的注水井的验封、分层测压技术也受到了越来越多的重视与应用。偏心注水井验封与分层测压能够有效验证封隔器密封工作状况与实际注水效果,是采油队进行注水调节工作的主要依据。在验封过程中,堵塞式压力计主要依靠地层压力、温度等参数验证封隔器坐封情况。
With the improvement of the technical level of oilfield development and the constant refinement of the development process, stratified waterflooding, as the main method of waterflooding in the oilfield, has drawn great attention from relevant production departments. At the same time, the related sealing and sealing of water injection wells, stratified pressure measurement technology has also been more and more attention and application. Eccentric injection well seal and stratified pressure measurement can effectively verify the packer seal working conditions and the actual water injection effect is the main basis for the production team to adjust the water injection. In the process of inspection, the plugged gauge mainly relies on formation pressure, temperature and other parameters to verify packer setting situation.
