本文根据斯仑贝谢公司双侧向测井仪DLT—E的工作原理,以获得最大测量功率为目的,提出一种新的功率控制方式,并与常见的几种方式(如恒流、恒压、恒功率等)进行分析比较,找出国产仪器动态范围小,特别是在高阻和低阻情况下效果差的原因,提出了改进设计的方案。 Based on the working principle of Schlumberger double-sided logging tool DLT-E, this paper proposes a new power control mode for the purpose of obtaining the maximum measured power, and compares it with several common methods (such as constant current, constant Pressure, constant power, etc.) were analyzed and compared to find the domestic instrument dynamic range is small, especially in the case of high resistance and low resistance under the effect of poor, put forward to improve the design of the program.
