SL3112组合测井系统的研制及应用

SL3112 Combination Logging System and Its Application

提出一种新的普通电极系与微电极测井仪研制思路,将4 m、2.5 m底部梯度及微电极的供电与测量转移到井下仪器中,再与专用的梯度电极系和微电极电极系结合,通过PCM3506编码通讯传输来测量底部梯度电阻率曲线和微电阻率曲线。该测井系统1次下井可测得9条曲线。重点介绍了系统的构成、工作原理及关键技术。应用表明该测井系统在提高测量精度的同时,大大提高了测井时效。

Proposed is a new idea to design the conventional electrode array log and minilog system which power supply and measurement of electrode array log and minilog were accomplished by the downhole. SL1600 azimuth and deviation logging tools redundant analog channels are efficiently used to encode and transmit most logging data to the surface log system. This new system can acquire nine curves at one logging run. Mainly introduced are the structure, operating principle and key technology of the little combination logging system. Field application shows that this logging system can improve measurement accuracy and logging efficiency greatly.
