【摘要】 补偿波电阻率测井是哈里伯顿公司随钻测井仪器LWD的电阻率测井项目。由于受泥浆污染小 ,用补偿波电阻率测井曲线求纯地层电阻率具有独到的优越性 ,但其测量结果仍受诸如井眼、各向异性等环境因素的影响 ,特别在大斜度井、水平井中。从补偿波电阻率测量原理出发 ,提出介电常数、井眼、围岩、侵入、各向异性等环境因素的校正方法 ,最后求出纯地层电阻率。该成果已投入生产 ,效果较好更多还原

【Abstract】 The compensated wave resistivity logging is a resistivity measurement of Halliburton′s LWD. For less contamination by mud, it is very advanced to determine the pure resistivity of formation from the LWD compensated wave resistivity measurements. But the results are affected by logging environments, such as borehole, anisotropy, and so on, especially in the high deviated hole and horizontal hole. Based on the compensated wave resistivity logging theory, we proposed a correction method of such environmental factors as dielectric constant, boreholes, shoulder beds, mud invasion, anisotropy, etc., then derived the pure resistivity of formation. This method is better in practical loggings.更多还原
