重复压裂工艺实用性概述与分析

Overview and Analysis for Refracturing Technology

重复压裂技术是低渗透油气田开发中后期稳油控水的重要技术措施,是提高压裂井产量的有效途径之一,可有效提高低产压裂井的产量,对能否成功地进行重复压裂具有重要的现实意义。本文综述了重复压裂裂缝的形成方式及压裂液和支撑剂的选用重点,并细致分析了重复压裂的选井选层原则,对从事重复压裂设计与施工的技术人员有着很强的实用性。

Refracturing technology is an important technical measure for remaining oil production and controlling water and among efficient path to advance the fractured well yielding in the middle anaphase of hyposmosis field development.It can effectivly increase the fractured well yielding.The success of refracturing is possessed of important operation significance.This paper sums up refracturing types,the emphases for optimizing break down agent and propping agent,and detailly analysing the principle for choosing well or layer about refracturing.It is the stronger practicability for the technologists who are engaged in refracturing design and engineering.
