Driller displayer capable of adapting to environment changes

Abstract

The invention belongs to the field of petroleum engineering, and particularly relates to a driller displayer capable of adapting to environment changes. The driller displayer comprises a communication unit, a CPU, a driver unit, a display screen, a power supply and a light ray sensor, wherein the communication unit comprises an optical coupling isolation receiving circuit which is communicated with an interface box and receives data of the interface box; the CPU is used for processing signals received by the communication unit, carrying out encoding processing on the signals, outputting the signals to the driver unit, receiving signals from the light ray sensor in real time and controlling brightness of a backlight lamp of the LCD display screen; the driver unit receives the signals from the CPU and drives the display screen to display orientations and hole deviation angles; the display screen is used for graphical display of the orientations and the hole deviation angles; the power supply is used for supplying electricity to the other units; the light ray sensor senses intensity of ambience light rays in real time and transmits sensing signals to the CPU. Light intensity of external environment is sensed through the light ray sensor, and the contrast ratio of the screen of the displayer and the brightness of the backlight lamp are adjusted in real time.

Description

Technical field [0001] The invention belongs to the field of petroleum engineering, and in particular, relates to a driller's display that is adaptive to environmental changes. The driller's display automatically adjusts the contrast of displayed graphics in real time and provides a directional display for directional wells. Background technique [0002] In oil and coal-bed methane extraction, the drilling operations of dual horizontal wells, connected wells and U-shaped wells are very technically difficult operations. Up to now, in directional drilling, wireless MWD (Measure While Dring) and LWD (Logging While Dring) are the main measurement methods for directional drilling at present and now. It can measure bottom hole data in real time and control wells well. Body quality. The bottom hole data measured in real time must be seen not only by the directional engineer but also by the driller on the derrick. The driller's display can display bottom hole measurement data in real t...

Problems solved by technology

[0003] The general measurement while drilling instrument is not equipped with light sensors, and the brightness of the driller's display is manually adjusted by the driller to meet the requirements, and there is still a distance between the driller's display and the operating platform, which is cumbersome to operate

[0004] The structure of the traditional driller display is as follows figure 1 As shown in the figure: 1 is the communication interface unit, 2 is the CPU processing unit, 3 is the display drive unit, 4 is the display unit, and 5 is the power supply unit; all drilling operations are performed outdoors, in deserts or Gobi, and the conditions are very harsh; Under strong natural light, it is difficult to see the display effect of the driller's display
