增产增注作业中的油层损害机理

Formation Damage Mechanism in Increasing Production and Increasing Injection Work

油田增产增注作业中的油层保护已越来越被人们重视,这主要是由于我国的油田大都处于开采中、后期,油田作业的频率比开采初期明显增高,显然,控制各作业环节对油层的损害,采取油层保护及预防措施,必然是提高作业效率的有效途径之一。本文重点阐述增产增注作业中的油层损害机理。

Oil reservoir protection in increasing production and increasing injection work of have more and more people＇ s attention in China. It is mainly because of the oilfield exploitation in China mostly in metaphase and later period of mining. The frequency of oil work is obviously higher than early stage. Apparently, it is one of the effective ways to improve work efficiency to control formation damage of each work link and take the reservoir protection and preventive measures .This paper mainly describes formation damage mechanism of Increasing Production and Increasing Injection Work.
