在勘探领域,探井的油水关系长期以来是一个难题,为了准确界定储层油水边界,在试油过程中会有目的地选择一些油水同层的储存井进行试油。油水同层储层井油水关系的影响因素呈现多样性,在完井技术上采取的是大套管射孔完井,一般以水平井或者大斜定向井钻探为主。通过诸如射孔技术与排液技术等试油工艺优化,可以实现控水增油目标或者在难以实现控制增油目标条件下,能够实现油水同流。
In the field of exploration, the relationship between oil and water in exploratory wells has long been a challenge. In order to define the boundaries of oil and water in reservoirs, some reservoirs of the same oil and water reservoirs are selected for oil testing during the test. The influencing factors of oil-water reservoir-oil-water relations show diversity. In the completion technology, large-casing perforation completion is adopted, which is mainly horizontal well or large inclined well. Through the optimization of test oil technologies such as perforation technology and drainage technology, it is possible to achieve the goal of controlling water and oil increase or to achieve the same flow of oil and water under the condition that it is difficult to achieve the goal of controlling oil increase.
