近年来,大庆油田开展了介电、测井方法的实验研究,取得了三点认识:(1)确定利用地层介电常数来划分油层和水层或水淹层的可能性;(2)确定利用基于电磁场理论建立起来的介电测井方法为最实用,特别是利用测量电磁场相位差参数划分油层和水淹层最为有利;(3)试制出相位介电测井仪,在井下进行了初步试验。

In recent years, experimental research on dielectric and well logging methods has been carried out in Daqing Oilfield. Three points have been achieved: (1) to determine the possibility of using the dielectric constant of the formation to divide the oil layer and the water layer or the water flooded layer; (2) to determine It is most advantageous to use the dielectric logging method established based on the theory of electromagnetic field to be most practical, especially to divide the oil layer and the water flooded layer by using the phase difference parameter of the measured electromagnetic field. (3) The phase dielectric logging tool test.
