新型三参数组合测井仪的应用

Application of a New Three-parameter Well Logging Combination Tool

介绍一种多功能测井组合仪,即新型三参数组合测井仪,它集微球、微电极、井径3种测井功能于一体,与伽马、连续测斜仪等测井仪器配接后一次下井可探测10余条测井曲线,是电法测井中主要应用的测井仪器。组合仪的主要特点是机械推靠系统采用双驱动六臂组合方式,井径系统采用各自独立动作的四臂井径腿,井径电位器采用无触点传感器,因此,大大提高了测量精度和测井时效,为油田勘探开发提供了真实可靠的地质信息,目前在大庆油田已经得到广泛的应用。

Introduced is a type of multifunction well logging combination tool （a new type of three-parameter logging combination tool） , which includes MSFL, ML and CAL. Combining with gamma-ray tool and navigation tool, it can gain more than 10 logging curves at one run, so it is the main electrical logging tool. The mechanical sonde mandrel assembly uses dual drive and 6- arm mode, the caliper system adopts four independent arms, the caliper potentiometer adopts non-contacting sensor, so, it greatly improves the logging accuracy and efficiency, and offers credible geology information for development of oilfield. Now, the well logging combination tool is widely used in Daqing oilfield.
