Description
Technical field:
The utility model relates to a kind of device that is applied to drilling well the pressure of the drill moment of torsion measurement while drilling in the petroleum drilling engineering.
Background technology:
In the drilling process, closely drilling engineering parameters such as the pressure of the drill at drill bit place, moment of torsion is crucial with boring accurately measurement to safety, efficient drilling well.Increase along with drilling depth; The exploitation of particularly multiple Multilateral Wells, horizontal well, fish-bone well; Various bit freezings, lost cone, the drilling tool drilling failure such as fall of breaking happens occasionally; The safety and efficiency of producing to drilling well brings very big influence, and the variation of measuring the drilling engineering parameters such as the pressure of the drill moment of torsion at nearly drill bit place in real time can prevent the generation of this type of accident effectively.Through accurately measurement in real time, can analyze, handle and contrast the actual well drilled process, and then instruct drilling process the nearly drill bit in down-hole place engineering parameter.As: rationally the confirming of mud equivalent circulating density, annular pressure detects with analytical technology etc.; Sum up the influence rule of each measurement parameter to drilling well process and efficient aspect; In time find and control some drilling failure, reach safety, the purpose of efficient drilling well, really realize the devoid of risk drilling well.
Known well drilling monitoring technology adopts surface torque appearance and weight indicator to measure moment of torsion and the pressure of the drill mostly, owing to the interaction process of the drill string in the drilling process and the borehole wall is complicated, calculates that by the ground survey data degree of accuracy that obtains nearly drill bit place engineering parameter is very poor.And drill string and drill collar receive the borehole wall of impact force that buoyancy and frictional force, drill collar transfer and elastic force, irregular borehole the centrifugal force of the frictional force of drill collar, the rotation of drill collar helical buckling and drill collar all are difficult for accurate Calculation in the longitudinal vibration of down-hole, horizontal factor such as shake in drilling fluid; Even if the prediction model Consideration is many again, calculate that result's the degree of accuracy and confidence level is also very low.As: in the drilling process of directional well and horizontal well, drill collar leans against or lies in the shaft bottom, can't only judge that with the pressure of the drill indicated value on the weight indicator of ground the shaft bottom really is added in the size of the pressure of the drill and the moment of torsion at drill bit place.In a word since the inaccuracy that ground instrument is measured and transmit data the time lag effect, calculate the with a low credibility of result even can't truly reflect the stressing conditions of down-hole equipment at all, all might cause the frequent generation of drilling failure.
The drill bit that uses in the oil drilling at present is divided into rock bit, diamond bit and drag bit three major types, and wherein: preceding two types of drill bits use more.Through the effect of drill bit rotation with the pressure of the drill, each tooth of drill bit alternately contacts bottom rock, makes catalase with effects such as impact, crushing and slip shear.Except that rotatablely moving, drill bit also has extensional vibration, and the frequency of extensional vibration is high, and amplitude is little.When adopting hole-bottom power drilling, mud motor is to deliver to the shaft bottom and lean on drill string and drill collar to bear reaction torque with drill string.When adopting rotary drilling, rely on drill string and drill collar to transmit the pressure of the drill and moment of torsion to the shaft bottom.In the actual well drilled process, might be the Combined application of two kinds of drilling modes, the engineering parameter Changing Pattern at nearly drill bit place be complicated more.
Drill collar is in creeping into, descend different drilling process such as brill, trip-out, and the stressing conditions and the forms of motion difference of drill string/drill collar different parts are very big.Mainly comprise: axial tension and pressure, moment of torsion, moment of deflection, centrifugal force, the inside and outside extruding of drill collar, extensional vibration, twisting vibration, side shake etc.Because the compound movement form of drill string and drill collar, drill bit have whirling motion phenomenon, shaft bottom the pressure of the drill to fluctuate in the shaft bottom very big, even the bouncing of drilling tool phenomenon that drill bit leaves the shaft bottom occurs.In theory, suffered power and the moment of drill collar can be reduced to: the pressure of the drill that drill bit is applied, transmit the moment of torsion of drill string, the moment of deflection that produces by drill string motion and shaft bottom reaction force and the drill vibration in the drilling process.From the angle of measuring technique, can be with the stressed moment of flexure effect that is reduced to axial the pressure of the drill and vibration, radially receives around axial pair of torque and drill collar of drill collar.
Both at home and abroad the developing focus of device for subsurface measuring is the measurement of geologic parameters such as the formation resistivity directly related with the oil-gas geology reserves, porosity, gamma ray always for many years; Measurement and control with how much well track parameters such as relevant hole deviation, orientation, tool face azimuth that lead; And less with engineering parameter Research on measuring technique such as drilling safety, the pressure of the drill that drilling efficiency is relevant, moment of torsion, annular pressures, retrieval finds only to have a spot of relevant therewith patented technology, analyzes comparison below respectively:
Known circular column draft, compress and reverse measuring technique and be based on the strain effect that tension and compression and torsional stress effect produce in the mechanics of materials, utilize the strain measurement principle to realize.To 0 °, 90 ° stickup foil gauges, obtain the size that cylinder receives the tension and compression active force along cylinder axis through the resistance variations of measuring foil gauge; To ± 45 ° of stickup foil gauges, obtain the size that cylinder receives torsional moment along cylinder axis through the resistance variations of measuring foil gauge; But this principle is applicable to the measurement of independent tension and compression effect, independent torsional interaction, can't directly apply to down-hole high temperature, high pressure, measured by the engineering parameter of combined stresses effect.
Practical work process based on above-mentioned measuring principle and downhole instrument; IFP had developed the first bench drill post mechanics parameter measuring instrument and had applied for patent in 1985; Famous subsequently oil instrument company, as: companies such as Schlumberger, Bake Hughes, APS have applied for relevant down-hole engineering parameter measurement pipe nipple patent in succession before and after 2000.These patents comprise United States Patent (USP): 6610935B1,4608861,4821563,4958517,5386724,6216533, European patent: PCT/US00/31685 etc.

Schlumberger and APS company have carried out further improvement to this technology; Through radially bore the hole of certain diameter, certain depth at drill collar; Foil gauge is sticked in the boring; With the high pressure sealing cover plate foil gauge is sealed in inside then, the contact conductor of foil gauge interconnects through the inside interface channel between the boring, and the measuring circuit that perhaps is installed in the drill collar wall groove in middle with the being installed in drill collar at last resistance to compression tube links to each other.The common ground of the two is the sealing problem that has solved protective sleeve, difference be embodied in radial hole arrangement, foil gauge lead-in wire connected mode and with the connected mode aspect of secondary change-over circuit.The shortcoming of this technology is also clearly: at first is relatively difficulty of inner lead hole processing, often needs processing respectively, and then welded together, perhaps adopt special instrument to process; Next is because the diameter of radial hole can not be too big, has caused very big difficulty for the stickup of foil gauge.The 3rd, the measurement characteristics of this device also shows certain non-linear, must be through just being applied to after ground scale and the verification in the middle of the actual measurement.
Except that the patent of above-mentioned leading company, domestic researcher also applied for the patented technology close with Baker Hughes Inc before and after 2005.As: CN 2076154U, ZL200420030034.7, ZL200320105002.4 etc.; Also have part company to carry out improvement and patent application to sealing problem, processing problems respectively abroad, but all do not change difficulty of processing, the contradiction between the sealing performance, measurement device characteristic three, therefore, the technical raising that does not have internal.
