摘 要: 油基泥浆微电阻率成像(OBMI)测井仪可以弥补油基泥浆和人工合成泥浆钻井无法采集常规电阻率成像测井资料的不足,获取井壁成像扫描图像。OBMI具有极高的垂向和横向分辨率(1.2in),清晰度和连续性好,可用于研究各种地质问题。通过OBMI测井解释,可以确定沉积能量、沉积构造、古水流方向及砂体延伸方向,从而进行沉积相分析,对指导油气田的勘探开发具有重要的意义。 A new oil-based mud micro-imager(OBMI) could compensate the drawbacks of not collecting resistivity logging imaging data in oil base mud and synthetic mud drillings and captured borehole scanning images.By using OBMI logging interpretation it could determine the sedimentary energy,sedimentary structure,palaeocurrent direction and sand body extension direction to study sedimentary facies.It provides guidance for the exploration and development of oil and gas fields.
