摘　　要：针对四十臂井径测井仪器在大斜度井中居中效果不理想,提出了加大扶正臂支撑力度、优化测井程序等改进方法,提高了仪器在大斜度井中的测量精度;为了提高测井资料解释精度,探讨性提出了斜井校正方法、变形段最小及最大井径值优化取值方法以及套管变形定量划分标准。实际应用结果表明,改进后的技术满足了中原油田对套损井检测及评价的要求。该方法对于其他多臂井径测井技术也具有一定的借鉴意义。Aiming at the insufficient ideal of centered effect of diameter forty arms logging instrument within high-inclination Wells,the measures to enlarge centralizer supporting strength to increase supporting ability and optimize logging program are suggested,thereby improving measuring precision of instrument in high-inclination wells.In order to improve the precision of logging interpretation,the correction method of high inclination well,optimizing minimum and maximum caliper value of down hole deformation section,plotting out casing deformation standard quantitatively are put forward.The result of actual application indicates that the improved technology can meet the requirement to check and evaluate the deformed casing in the high inclination wells in Zhongyuan oilfield.This method has some certain significance for other multi-armed caliper logging technology.
