摘要
我国大多数油田长期沿用着原始的洗井方式,要么是先采用柴油浸泡,然后用地热水或过滤海水洗井,要么是用油溶性清洗剂进行洗井,但两种方式都很难满足实际需求。文章针对该问题,开发了一种W/O柴油基洗井液,对该洗井液体系的流变性、稳定性、清洗性能以及对储层的保护性能进行了全面的考察,能很好的满足现场施工的要求。
Most oilfields in China have long followed the original well washing methods, either well soaked with diesel firstly, and then washed with hot water or filtered sea, or washed with oil-soluble cleaning agent, but both of the two ways are very difficult to meet the actual demand. For the problem, a water in oil well washing fluid based diesel is developed, comprehensively studied rheology, stability, cleaning performance and the protective properties of the reservoir for the Well washing fluid system, which can well meet the requirements of on-site construction.
