气体钻井条件下AdvantageⅡ综合录井仪数据采集的优化配置

Optimized configuration of data acquisition for Advantage Ⅱ mud logging unit under gas drilling condition

由于国外引进的新型综合录井仪如ALS、AdvantageⅡ等无法直接对气体钻井条件下增加的录井参数进行采集、存储、显示,需要在硬件、软件两方面对其予以优化配置。硬件部分的优化配置主要是在原有的采集系统中增加传感器信号采集的隔离栅模块,并对其接线方式进行调整;软件部分的优化配置主要是在采集、传输、显示软件的配置文件中对增加的传感器参数进行通道分配、字段定义、单位调整。优化配置后AdvantageⅡ综合录井仪能够适应气体钻井条件下数据采集的要求,从而扭转了国外引进仪器不能用于气体钻井条件下录井的困境。

Because the imported new mud logging units such as ALS,Advantage Ⅱ can not directly collect,store and display the increased mud logging parameters under gas drilling conditions,it needs to be optimized in the configurations of its hardware and software.The optimized configuration for hardware mainly increases isolation barrier module of the sensor signal acquisition in the original acquisition system,and adjusts its wiring.The optimized configuration for software mainly performs channel assignment,field definitions,and unit adjustment to the increased sensor parameters in configuration files of acquisition,transmission and display software.After optimizing the configurations,AdvantageⅡ mud logging unit is able to adapt to the data acquisition requirements under the condition of gas drilling,thus reversing a trend that the imported mud logging unit cannot be used under the condition of gas drilling.
