强水敏地层提高注水能力的预处理技术

Pretreatment Technique for Enhancing Water Injection Capacity in Strong Water-sensitive Formations

介绍了宝浪油田宝北区块低孔低渗且强水敏储层注水井油层损害的机理、保护油层的注水井预处理技术室内研究及现场试验取得的效果情况，为低孔低渗油气田强水敏储层的注水开发提供了成功的经验．

This paper introduces the formation damage mechanism of the low porosity and low permeability and strong water-sensitive reservoirs in the water injectors in Baobei Block, Baolang oilfield, the laboratory research results of water injector pretreatment technique and the field pilot effects. It provides successful experiences on waterflooding in strong water-sensitive reservoirs in low porosity and low permeability oilfields.
