摘要
随着油田开发进入中后期,老井重复压裂是老油田增产稳产的重要措施。如何提高重复压裂的有效性,最大限度动用剩余油气富集区,是老井重复压裂重点关注的问题。本文对重复压裂选井选层原则和主要重复压裂工艺技术进行调研,为老井重复压裂施工选择合适的压裂方法提供参考。
In the middle-later development period of oilfield,refracture is an important measure to increase and stabilize production in old oilfields.How to improve the effectiveness of refracturing and maximize the oil recovery are the key issues to consider.In order to select suitable methods to refracture for old wells,the principle of wells and layers selection and major refracturing technologies was investigated.
