Technical background
In the geology drilling process of modern subterranean resource, Geological Engineering, mine, oil, salt industry, coalfield, metallurgy, large hydraulic engineering, engineers and technicians will be promptly and accurately geologic information, drilling track, the orientation of creeping into, situation and the information thereof of drilled strata of grasp drilled strata, engineers and technicians can make decisions in time or adjust in time according to down-hole information, drilling tool under control well carries out work according to the wish of driller, for reaching this purpose, engineers and technicians will solve the transmission problem of drilling information.
The transmission of drilling information at present, particularly the drilling information on ground is all to adopt wire transmission substantially, namely stube cable, when well data information exchange overvoltage Reeb is from the underground high pressure vertical tube that is transferred to ground, pass through again pressure sensor, namely signal detection module, detect the variation of high pressure vertical tube pressure oscillation, conventionally the high pressure vertical tube pressure wave signal receiving is to be transferred to control machine room by wire cable, but this wire cable transmission means exists a lot of shortcoming and defect in job site in the wild in using:
1. holding wire causes decay and the distortion of signal after long-distance transmissions, is also easily subject to noise jamming and causes error code.
2. due to construction in the wild, cable transmission easily causes thunderbolt, damage equipment, and severe patient causes fire and electric shock accidents.
Due to rig in operation in vibrational state, cable easily weares and teares, and causes leak source and loose contact, affects efficiency of construction.
4. wire cable brings the inconvenience in installation and removal process to site operation.
Summary of the invention
The present invention is in order to overcome above-mentioned shortcoming and defect, adopt terrestrial wireless transmission means, thoroughly break away from wire cable and transmitted a series of disadvantages of bringing, there is transfer rate fast, the bit error rate is low, conveniently moving, has avoided easily damaged and easy thunderstruck phenomenon of cable, brings great convenience to field construction operation simultaneously.Object of the present invention is exactly for the situ of drilling well such as geological prospecting, oil, coalfield, metallurgy provide a kind of oil drilling MWD wireless pressure sensor radio transmitting device.
To achieve these goals, technical scheme of the present invention is: MWD wireless pressure sensor radio transmitting device for a kind of oil drilling, comprises slush pump, derrick, standpipe, down-hole part and aboveground part, down-hole part has inserting tube, battery, pulse driver, impulse generator, drill collar, drilling fluid, is characterized in that aboveground part comprises that pressure sensor signal receives Check processing part, rig control room, driller's display instrument signal receive section, they are wireless connections, pressure sensor signal receives Check processing part and comprises signal detection module, current/voltage-converted circuit, filter amplification circuit, A/D conversion circuit, single-chip microcomputer, radiating circuit, transmitting antenna, they are integrated and connect, and rig control room comprises computer, radio receiving transmitting module, they are integrated and connect, and driller's display instrument signal receive section comprises driller's display instrument, wireless receiving module, reception antenna, they are integrated and connect, and radio receiving transmitting module one end and pressure sensor signal receive the wireless connections of Check processing part, the other end and computer wired connection, reception antenna one end and rig control room wireless connections, the other end and driller's display instrument wired connection.
Beneficial effect of the present invention, because terrestrial transmission adopts wireless transmission method, thoroughly break away from wire cable and transmitted a series of disadvantages of bringing, there is transfer rate fast, the bit error rate is low, conveniently moving, has avoided easily damaged and easy thunderstruck phenomenon of cable, brings great convenience to field construction operation simultaneously.
