摘要
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。
To solve the water sensitive damage problem existed in low and extra-low permeability reservoirs, a multiple statistics was used to identify the main factors affecting upon water sensitive damage and establish the mathematical model for quantitative prediction of reservoir's water sensitive damage. The prediction of water sensitive damage in low and extra-low permeability reservoir made by the model exhibits good coincidence with lab result. The coincidence rate of prediction is greater than 85%.
