Technical Field
The invention relates to a product for making stratum evaluation in the drilling operation process of petroleum, coal bed gas and the like, in particular to an azimuth gamma modular structure of an underground instrument.
Background
Horizontal well sections in oil and coal bed gas drilling operations are typically located in reservoirs. When a horizontal well section is drilled, unknown fluctuation and direction change exist due to complex distribution conditions of a reservoir stratum, a well track sometimes deviates from the reservoir stratum, and subsequent acquisition efficiency is influenced.
In the development process of oil and gas, directional wells and horizontal wells are increasingly used. In order to ensure that the well bore advances in the oil and gas reservoir, logging-while-drilling equipment is rapidly developed. The azimuth gamma measurement is used for making more ready evaluation on the stratum, and whether the well hole deviates from the reservoir can be given out and used as an important basis for geological guidance, so that the productivity of the oil-gas well is greatly improved.
At present, the existing azimuth gamma module has a redundant structure, the volume of equipment while drilling is limited, and the existing azimuth gamma module cannot be suitable for different boreholes.
