摘　　要：砂砾岩储层压裂时裂缝容易发生不规则扭曲,具有多裂缝、滤失大、摩阻高等特点,为了测试影响裂缝壁面摩阻的相关因素及影响程度,设计并制作了砂砾岩裂缝壁面摩阻的测试装置,测试并分析了相关因素,获得砂砾岩摩阻的增长规律,拟合回归出砂砾岩裂缝摩阻公式,误差小于10%,用于预测砂砾岩储层施工时的裂缝摩阻,为确定施工压力,优选施工工艺及参数提供依据。The fracture created in glutenite reservoirs by hydraulic fracturing will distort irregularly, the fracturing has the features of multiple-fractures, high filtration and high friction. In order to test the influence factor of the friction and difference of degree, the device to test the fracture fiction in glutenite reservoir is designed and manufactured. The laws of friction growth is obtained through analyzing the related factors , and a formula for calculating the friction in glutenite reservoir is obtained , its error is generally less than 10% ,it can be used to predict the friction in fracturing design and treatment, and it provide a basis for calculating fracturing pressure and the project selection.
