Description
Technical field
The present invention relates to oil exploration equipment technology, attachment structure that espespecially a kind of data rod, drill collar and internal pipe nipple are formed and connector for logging while drilling.
Background technology
Measurement while drilling (MeasureWhileDrilling:MWD) and well logging during (LoggingWhileDrilling:LWD) have been wide-angle and horizontal well drilling, the data acquisition of real-time well site, explanation, decision-making in-situ and guidance complete the key technology of geologic steering drilling, it combines the multiple subject technologies such as record well logging, drilling well and reservoir description, drillng operation program can be simplified, save cost, improve drilling well precision, adjust Drilling Design and improve recovery ratio.
It is generally acknowledged that LWD includes MWD.Connector for logging while drilling is generally with pipe nipple for functional unit, and the instrument of every kind of function individually becomes a pipe nipple, for instance: resistivity logging while drilling pipe nipple, with boring neutron density pipe nipple.LWD mainly includes following pipe nipple: power supply pipe nipple；Various engineering parameters, formation parameter measures pipe nipple；Slurry pulsator transmission pipe nipple.Wherein mud-pulse transmission pipe nipple and data collecting system, ground demodulating system constitutes mud-pulse the spread of the rumours system, and mud-pulse the spread of the rumours system is the important component part of so-called MWD.
As shown in accompanying drawing 1 systematic schematic diagram, two-forty mud-pulse the spread of the rumours system principle of a new generation is at present: in drilling process, underground survey sensor records engineering parameter and formation parameter, these analogue signals recorded, by data encoder, be converted to digital signal.Digital signal is after control circuit is modulated, control signal after modulation is passed to drive circuit, drive circuit controls motor movement from power supply pipe nipple power taking, will through communicating circuit when turbogenerator is powered, communicating circuit can realize other functions of pulser pipe nipple according to actual needs, motor moves according to the control signal that control circuit is given, drive slurry pulsator rotor to rotate or swing, the rotor of pulser shears fluid, produce pulse signal, these pulsating pressure signals, through drill pipe transmission to ground, the pressure transducer on ground is acquired, transmit, by the pressure signal of demodulating system down-hole, the data come up to resolve, obtain underground engineering parameter and formation parameter.
Mud pulse generator the spread of the rumours system is the most important components in MWD, LWD equipment, is the down-hole information important means that is transferred to ground in real time.Along with the development of formation evaluation technology, downhole data amount is being gradually increased, it is necessary to the more pulser of high transfer rate, and the transfer rate of mwd system is increasingly becoming the bottleneck that restriction downhole data is uploaded.
In connector for logging while drilling, each function pipe nipple, generally by drill collar, INSERT etc. is constituted.Outside drill collar, as protection cylinder, for external seal in drill string, bears torque and the pressure of the drill when creeping into, make a trip, bear pulling force when promoting drill string.Inside is INSERT structure, between drill collar inwall and INSERT, forms sealed compartment, places circuit board, be also known as electronic compartment inside sealed compartment.Drilling mud is passed through by endoporus in the middle of INSERT.Inside pipe nipple, when instrumental function conversion needs to transfer, sometimes have fluid passage conversion, for the joint of runner conversion, be called runner adapter.
Electronics cabin, is sealed by drill collar inwall and electronics skeleton outer wall and is formed, be used for placing circuit board, the Various Functions of these circuit boards, have control, drive, central authorities' control etc..Wherein the chip functions parameter of circuit board is sometimes for configuration, and chip program is sometimes for renewal, it is sometimes desirable to power to drive instrument according to set orbiting motion to instrument internal, it is sometimes desirable to read the data of storage during instrument underground work.The communications protocol appointed is used to carry out communication between pipe nipple.Such as using 1553 agreements etc., available single core cable realizes signal and electric power transmission, realizes electronic compartment interior circuit board by bus or communications protocol, and communication and the signal between pipe nipple transmits.
Test at laboratory, and well site measures before work starts, when needing to utilize data rod to carry out the operations such as configuration, generally use single connector data rod, carry out digital independent, and further program chip programming, then need to take out INSERT, directly utilize the multicore socket connector on circuit board on circuit boards and be written and read operation, waste time and energy.Crossing line for bus with brill instrument internal, current instrument is all by runner conversion, and namely intermediate flow channel is converted to annular fiowpath, or annular fiowpath is changed to hollow duct.
At present, along with the development of oil drilling technology, increasing drilling parameter and formation evaluation parameter need to be uploaded in real time, the requirement of the data transmission rate in well logging during and the bit error rate is also improved constantly, need transfer rate higher, more structurally sound signal the spread of the rumours system.Mud-pulse method is comparatively reliable in numerous information transmission mode, the transmission means being most widely used.
In the world, adopt reciprocating continuous wave pulse generator can realize the data transmission rate of 15bps under 7000m well depth, and the domestic data compression technique that utilizes, make positive interaction pulse generator data transmission rate reach 4bps.
Generally, the fields such as the domestic pulser that there is no independent research is for commercial use at present, and from the principle of mud pulse generator to manufacture, downhole data compresses, modulation, filtering noise reduction demodulation, all there is bigger blank.When MWD instrument works in laboratory cyclic test and well site, all needing to carry out condition monitoring, parameter arranges to wait and operates.
In oil well logging instrument, the transmission between pipe nipple inside and pipe nipple of signal and electric power is the problem needing in instrument design to consider emphatically.
And the actuator of a new generation's pulser has moving parts, there is pressure compensation and movable sealing.Existing changed by runner, use the wire laying mode of single connector to there is difficult design.Additionally, need externally fed or the ruuning situation of monitoring motor for slurry pulsator, use the wire laying mode of single connector also can not meet these functions or the operation requirement of instrument.
When instrument is circulated test in laboratory, INSERT loads in pipe nipple, by torque wrench moment between pipe nipple, utilizes the sealing surface of drill collar to realize the sealing between pipe nipple.During cyclic test carries out, it is necessary to monitoring running situation, after having tested, the circuit board chip data on INSERT circuit framework needs reading etc., and single connector is clearly inadequate.For rotary transformer, it is desirable to have 6 cables are monitored motor position and followed the tracks of situation.Sometimes work as system power supply, namely when turbogenerator power supply instability, it is necessary to from externally fed, now can realize electric power transmission with multicore socket connector, power to instrument internal.
Before instrument operation, at situ of drilling well hole condition, it is necessary to carry out parameter configuration, for instance the modulation parameter of control circuit, the pid parameter etc. of motor servo control.All need according to drilling condition, such as well depth, slush pump discharge capacity, mud density, mud viscosity etc., be controlled parameter, the configuration such as modulation system.
