| 摘 要： | 甲酸盐泥浆可以稳定井壁,保护油气层.由于采用甲酸盐泥浆导致电阻率测井曲线明显降低,给测井识别油水层、确定含油饱和度带来难度.为了解决这一难题,通过岩心驱替实验,建立地层真电阻率和视电阻率比值与地层孔隙度、地层水电阻率和注入流体电阻率的关系,对电阻率曲线进行了校正.经过13口井的实测曲线的验证,校正后的电阻率曲线能正确区分油水层.

| Abstract: | Because formate-mud can stabilize the borehole wall , the oil and gas beds will be protected, but better resistivity logging curves will not be obtained, so it is difficult to identify oil and water and determine oil saturation . To solve this problem , we found out the relation between the ratio of real resistivity to apparent resistivity, and formation porosity, as well as the relation between water resistivity and injected liquid resistivity through core displacement tests to correct the curves. The curves obtained from 13 wells show that the corrected resistivity curves are available to correctly identify oil and gas zones. |
