摘　　要：近年来,工区内塔河、顺北等以超深层碳酸盐岩为主要目的层的油气田,存储式测井应用逐年增加。上、下测进套管双侧向仪器都在测井档工作,曲线较完整。以往文献资料主要论述了双侧向测井工艺、仪器故障等,对简单的套管内测井数值研究内容涉及较少,根据电缆测井规范和仪器原理,通过用双侧向的电压比电流来拟合名义电阻率,进行套管内电阻率测井数值研究,对井下仪器工作的稳定性和曲线质量做出一些辅助的评价。从工区内三种常见的直推式双侧向仪器特点入手,选取近两年来34口井测井资料,拟合并分析了三种直推式双侧向的套管测井值形态和数值特点,列举了三个名义电阻率测井应用实例,提出了辅助QC方面的建议。对同行有借鉴意义。In recent years,the application of storage logging has been increasing year by year in oil and gas fields such as Tahe and Shunbei in the work area,which mainly target ultra deep carbonate rocks.Both the upper and lower instruments are working on the logging mode,and the curves are relatively complete.According to the specifications and instrument principles of cable logging,the nominal resistivity is fitted using a bilateral voltage to current ratio to conduct numerical research on the resistivity logging inside the casing,and some auxiliary evaluations are made on the stability and curve quality of downhole instrument operation,Starting from the characteristics of three common direct-pushed Dual laterolog instruments in the work area,34 well logging data from the past two years were selected.The morphology and numerical characteristics of the casing logging values of the three types of direct-pushed Dual laterolog instruments were planned and analyzed.Three examples of nominal resistivity logging applications were listed,and suggestions for QC were proposed.Previous papers mainly discussed the Dual lateral logging technology,instrument failures,etc.,with less involvement in the numerical research of simple casing logging,which has reference significance for peers.
