Water injection performance analysis and fine potential tapping Countermeasures in heterogeneous reservoir

Abstract

After the heterogeneous reservoir enters the middle and late stages of development, the problems due to water injection will become increasingly prominent. However, the requirements for water injection in reservoir development are also increasing. So how do we solve this big problem? And how to scientifically manage water injection wells, promote oil with water, improve water displacement efficiency, and make the reservoir enter a benign development state? First of all, we need to firmly remember the idea of “water well first, pay equal attention to oil and water”, lock the key points of water injection, and comprehensively improve the water injection management level from the aspects of surface, wellbore and underground, so as to consolidate the foundation of stable oil reservoir production.
