Problems solved by technology

[0002] The MWD measures the well inclination and azimuth information in real time during the drilling process, and sends the detected information to the ground interface box through the transmission medium for decoding. The decoded data is displayed on the driller's display. Due to the harsh environment of the drilling site , It is difficult for ground operators to distinguish the information on the display screen under strong light environment, which affects the display effect of the driller's display, thus misleading the ground operators to make wrong analysis and decision-making on the bottom hole condition

Abstract

The invention discloses a light ray sensing driller display system which comprises a power management system, a light ray sensing system and a driller display system. The light ray sensing system and the driller display system are connected to the power management system, and the light ray sensing system is connected to the driller display system. The light ray sensing driller display system has the advantages that the display brightness of screens can be automatically adjusted according to change of external light rays in real time, and accordingly the light ray sensing driller display system can bring convenience for ground operators when the ground operators read and analyze data.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling, in particular to a light-sensing driller display system. Background technique [0002] The MWD measures the well inclination and azimuth information in real time during the drilling process, and sends the detected information to the ground interface box through the transmission medium for decoding. The decoded data is displayed on the driller's display. Due to the harsh environment of the drilling site , In the strong light environment, it is difficult for ground operators to distinguish the information on the display screen, which affects the display effect of the driller's display, thus misleading the ground operators to make wrong analysis and decision-making on the bottom hole situation. Contents of the invention [0003] The object of the present invention is to provide a light-sensing driller display system. [0004] For this reason, technical scheme of the present invention i...
