Abstract:
In the oil fields developing it is necessary to know the strength of the rock for competent voltage detection in situ, the analysis of wellbore stability and other parameters.
Knowing these parameters is required for the formation of the well and further operations such as mining and drilling voltage change in formations.
There are several types of complications: landslides, debris, disclosure of drilling mud, fluid inflow. The main reason for such manifestations is the excess pressure in the reservoir relative to the borehole.
When opening, a hole space is replaced with a washing liquid, which changes the thermal stress.
