近年来,随着油田开发的深入,定向井及大斜度逐年增多,常规测试密封胶筒外径大于刚体外径,工具的上胶筒、密封件和刚体过盈配合,在定向井中起下作业时,胶筒和密封件磨损严重,不能有效密封,无法满足注水井单层流量直测、分层流量测试、封隔器验封测试施工的技术要求。本文涉及在辽河油田金海采油厂进行使用的一种定向井分层测压封隔器,具体说是一种具有自动内部调节的固定分层密封效果的测压封隔器。
In recent years, with the deepening of oilfield development, the directional well and the large slope increase year by year, the outer diameter of the conventional test sealant cylinder is larger than the outer diameter of the rigid body. The sealant, the seal and the rigid body of the tool are in interference fit, In the next operation, the rubber cylinder and the seal wear seriously and can not be sealed effectively, which can not meet the technical requirements of straight flow measurement, stratified flow test and packer seal sealing test in the injection well. This article relates to a directional well layered pressure-measuring packer for use in the Gim-oil Production Plant in Liaohe Oil Field. Specifically, it is a pressure-measuring packer with a self-contained, internally regulated, stratified seal.
