Description
Technical field
The utility model relates to the wireless drilling inclinometers of the multi-operation mode in the drilling engineering deviational survey field in oil, colliery and the geological prospecting.
Background technology
Present drilling engineering inclinometer industry in oil, colliery and the geological prospecting mainly contains the many throw-in types of electronics, electronics single-point and hangs four kinds of survey formula and self-floating, wired drilling and wireless drilling (MWD) modes.The pluses and minuses statistics of using separately is as follows:
Many throw-in types of electronics measuring method is instrument to be dropped into sink in the drilling tool in the non magnetic drill collar, pulls out of hole then, and instrument writes down the well bore parameter automatically, and advantage is record well bore data, draws out the chart of specialty, the display well track, and shortcoming need be mentioned drilling tool, operation inconvenience.
It is that inclinometer is transferred to desired location by winch that the electronics single-point hangs survey formula measuring method, measures by carrying instrument on the winch.The advantage of this measuring method is that drilling tool remains static, and the data of measurement are reliable, and shortcoming is to use winch instrument is transferred and to mention, and need expend a large amount of time, and can only measure the data of a position at every turn.
Electronics single-point self-floating measuring method is that the self-floating inclinometer is dropped in the drilling tool hydrophthalmia, connect the kelly bar circulating fluid then, the self-floating inclinometer is poured the shaft bottom, intact back termination of pumping to be measured, and dismantle kelly bar, the automatic emersion well head of instrument meeting takes out the data that instrument obtains underground survey then.This method can stop to bore measurement at any time, do not need winch, but shortcoming is to measure the data of a position at every turn.
The wired drilling mode connects instrument and transmits power supply and exchange survey data through ground to instrument by a single core armored cable that is contained on the winch, transfers instrument to the shaft bottom deviational survey by winch.The advantage of this mode is to measure continuously and in real time, shortcoming is because the restriction of cable, each increase and decrease one joint drilling rod all needs to play instrument next time with winch, and the fault that cable twists off takes place easily cause whole cable to be scrapped, also to have supporting with boring engineering truck, operation and maintenance cost height.
Mud-pulse wireless drilling (MWD) mode is that instrument is transferred to the shaft bottom, and the data of measurement are sent to ground by the mode of mud-pressure pulses.This method can the continuous measurement down-hole data, but be subjected to the influence of transmission medium, the speed of transfer of data is low, the data of common every bit need the time more than 1 second, thereby data quantity transmitted is limited, cost is very high.And communication modes is unidirectional, can only be by mud to aboveground transmission data, and battery is in the power consumption state always in the use of down-hole, battery capacity is required high.
Summary of the invention
For solve existing mud-pulse wireless drilling (MWD) inclinometer data transmission bauds rate low, can only one-way communication, to the demanding deficiency of battery capacity, in conjunction with the advantage of electronics list multiple shot tool and steering tool, the utility model provides a kind of wireless drilling inclinometers of multi-operation mode.The technical scheme that its technical problem that solves the utility model adopts is: data carrier device and downhole instrument assembly are by the mode of operation of electromagnetic wave contactless communication with transmission data or change downhole wireless directional tool.Data carrier device is connected to form by fishing spear, buoyant cabin, snubber, carrier communication pipe nipple.The downhole instrument assembly is to be connected to form by underground communica tion pipe nipple, centralizer pipe nipple, main battery tube, inserting tube pipe nipple, secondary cell tube, impulse generator pipe nipple.Buoyant cabin is formed by connecting by the tube by the more piece hollow structure, makes the mean specific gravity of data carrier device less than 1.0.Snubber is the hydraulic damping device of a piston structure, is used for alleviating data carrier device when well is descending and the impact of downhole instrument assembly, prevents instrument damage.Carrier communication pipe nipple and underground communica tion pipe nipple are in immediate position, be convenient to reduce electromagnetic loss between the two, be mounted with 4.8V power supply and communication coil in the carrier communication pipe nipple, be mounted with communication coil and data storage circuitry plate in the underground communica tion pipe nipple, in order to the transmission of the storage that realizes the down-hole image data and transfer, mode of operation instruction.
The beneficial effect of this utility model has: have multiple mode of operation: MWD with boring, gather in batches, saving.Do not need logging winch and cable, merged the advantage of mud-pulse wireless drilling inclinometers and self-floating inclinometer, not only can measure hole trajectory data in real time, and do not need auxiliary equipment such as cable reel.Expanded traditional communication modes of MWD aspect communication performance, generated electromagnetic waves by the coil mutual inductance and carry out two-way communication, than mud-pulse communication more accurately and reliably, and transmission speed is fast, capacity is big.The data of measuring all have the real-time clock label, the convenient real effectiveness of judging initial data.Close the pulser pipe nipple under the save mode, save battery loss.
