Title:
ボーリング孔内の検層方法および該検層のために用いられる水中浮遊型カプセルプローブ。
Document Type and Number:
Japanese Patent JP6997924
Kind Code:
B2
Abstract:
To reduce the equipment, period and cost significantly and to improve the accuracy of a logging, by simplifying an installation of a probe equipped with a sensor when logging in a borehole.SOLUTION: The status of the wall surface inside a borehole is logged based on recorded information obtained by using a watertight capsule probe, which is equipped with a water pressure sensor and means for recording sensing information of the water pressure sensor, to be allowed to self-float in the water in the borehole in the vertical direction. As a result, it is not necessary to use a rod or the like or a packer for lifting and lowering the measuring device, and it is possible to reduce the cost, shorten the period, and improve the measurement accuracy.SELECTED DRAWING: Figure 1
