新型一体化四参数组合测井仪的研制

Development of the new four parameters integration logging tool

文章介绍一种新型一体化四参数组合测井仪,该仪器一次下井可同时测取井温、压力、磁定位、伽马四个参数。该一体化仪器相对于以往四参数仪器,降低了测井风险,改善了温度响应滞后以及压力测量精度。测井实践表明该仪器具有结构简单、测井风险小、测量结果精度高、响应时间快、仪器维修方便等特点,具有较好的推广价值。

This paper introduces a new four parameters integration logging tool. The tool can measure four parameters at the same time, they are temperature, pressure, casing collar locator and gamma. The tool relative to the previous four parameters can reduce the logging risk and improve the temperature response lag and pressure masurement accuracy. This logging practice shows that the tool has simple structure,small risk,high measuring accuracy, rapid response rate and easy maintenance,and it has much value to be spread.
