摘　　要：岩性密度仪用于探测地层的体积密度(ρ)和光电吸收指数(PE),同时还具有井径测量功能。仪器在使用过程中,经常出现刻度不能通过、不能判断井径臂开合是否到位等问题。文章针对这些问题,总结介绍了一些经验和解决的方法,以便与同行分享与技术交流。The Z-Density instrument measures both formation bulk density( ρ) and the photoelectric absorption index( Pe). It also measures the borehole size. During the operation of the tool,there are usually the problems that the calibration can't be passed and the caliper can't be opened or closed properly. This paper summarizes a lot of experience and some solutions to these problems.
