治理中,低渗透油田作业污染的措施

根据现场调查和相关理论分析，探讨中、低渗透断块油田在生产过程中对油层的污染因素，研究制定相庆的对策和应用技术，主要是三种油层保护管柱；井保护管柱，多功能油层保护管柱，不压井作业管柱，从而有效解决了清蜡洗进污染、层间干扰污染和压井作业污染对油层的伤害问题，对于经济、高效地开发中、低渗透油田具有重要的意义。

Research On Production Operation in Low-Mid Permeability Oil Field

This paper gives a discussion on reservoir contamination during oil production in low-mid permeability oil field. With the field investigation and relative studying achievements, we draw a conclusion that three main kinds of oil-layer protective pipes, protective pipe for washing well, protective pipe of multipurpose oil-layer and operation pipe of nonpressured well, can be used, so the damaging problems which result from paraffin removal during washing wells, layers interference and killing job have been solved. These techniques are important to explore the low-mid permeability oil field econdrically and efficiently.
