针对低渗和特低渗储层存在的水敏损害问题，利用多元统计方法确定了影响水敏损害的主要因素，并建立了储层水敏性损害定量预测的数学模型。该模型对低渗、特低渗储层水敏损害程度的预测结果与室内试验结果具有很好的符合率，其预测符合率达到85％以上。
According to the problem of water damage in low permeability and ultra low permeability reservoirs, the main factors affecting water damage were determined by using multivariate statistical method. A mathematical model for quantitative prediction of reservoir water sensitivity damage was established. The model has a good coincidence rate with the laboratory test results for the water damage of the low permeability and ultra-low permeability reservoirs, and the predicted coincidence rate reaches more than 85%.
