Description

The downhole parameters direct reading test all-in-one that is used for oil field vertical shaft and horizontal well

Technical field

The utility model relates to a kind of downhole parameters direct reading test all-in-one that is used for oil field vertical shaft and horizontal well.

Background technology

Down-hole electronic thermometer and electronic pressure gauge are generally adopted in the formation testing test of domestic oil field, obtain bottom hole flowing pressure, static pressure, barometric gradient, pressure build-up curve, drop of pressure curve and technical data such as temperature curve, interference and Well Test Curve.Accomplishing the technology of downhole parameters direct reading test at present, all is to adopt armored cable connection collector and weight linear meter band pressure to rely on gravity to sink to the down-hole to implement test.Armored cable is to have installed a circle steel wire sheath additional in the cable periphery, and main effect is tension strength and the abrasion resistance in order to strengthen cable.The diameter of the armored cable that now uses is 5.56mm; Weight is about 150kg/1000m; Ignore down-hole weight linear meter length gradient pressure that produces and the buoyancy that the weight linear meter volume produces and disregard, because the cable that connects collector and weight linear meter is outside well, the axial pressure of cable along the line is zero; Make cable and collector junction pressure disappearance and produced pressure reduction; So collector and weight linear meter sink must overcome the buoyancy that pressure reduction causes, the sectional area of armored cable causes the pressure reduction of collector and weight linear meter to equal cable sectional area * pressure (cable diameter * 3.14 * pressure), is 5.56mm by cable diameter; Pressure is that 10MPa calculates, and the buoyancy that is produced is 28.26kg.When if the pressure at down-hole measuring point place is 60MPa, buoyancy is 169.56kg, so counterweight must just can make collector sink greater than 170kg.And the diameter of weight linear meter generally can not surpass 36mm on request, and the proportion of weight material is generally 11～15, and the length of weight linear meter will be about 17 meters～13 meters so.The practical implementation method of oil well formation testing test Operating Pressure is: cable is connected collector in elder generation and weight linear meter is encased in the lubricator of production tree top sealing; And then open production tree oil well valve passage; Let the collector and the weight linear meter of suspention crash in the well; Through winch cable and sealing chute, rely on gravity that collector is put into the oil well shaft bottom.If weight linear meter length is 15 meters; The lubricator length of Operating Pressure just is greater than 15 meters so; The open-air completion presses 15 meters long weight linear meters into the such job engineering in shaft bottom from the high lubricator band of erectting more than 15 meters, must multiple main equipment (cable car, generator, crane, high-pressure pump and equipment are transported car) and a large amount of engineering staff cooperate and could ensure enforcement.The construction operation in the desert region of remoteness, its engineering cost is very high, and the site operation personnel is dangerous and labour intensity is big, so generally seldom use in the reality.In most cases, all be that to adopt diameter be that the steel wire of 3mm hitches and stores in the down-hole after collector is put into the shaft bottom image data earlier in the reality, treat that pressure gauge and thermometer proposition ground is handled to obtain downhole data again.The data that the method obtains lag behind, and are easy to miss the chance of obtaining achievement, and need frequent in oil well, removing, and it is many to employ train number, and operating efficiency is very low, can not satisfy the actual demand on the modern production.Obviously, be not suitable for the test of horizontal well yet.

This shows that causing the heavy main cause with a large amount of expenses of generation of downhole parameters direct access mode test jobs engineering is diameter and weight into the well cable.In downhole parameters direct reading test technology, the effect first load-bearing of cable is wanted to bear several kms and is gone into the deadweight of well cable and the weight of collector and weight linear meter.When carrying on the cable, cable also will bear well head sealing chute frictional resistance and down-hole fluid and cable and weight linear meter and produce the resistance that friction causes cable; Its two be the power supply, working power is provided for the down-hole collector; It three is communication, signalling channel is provided for down-hole collector and GDHS.The deadweight of cable is a principal element in the factor of cable load-bearing, because the weight of weight linear meter can reduce through reducing the line footpath significantly; Well head seal friction power can reduce through adding packing grease; Fluid can reduce through the control upward strain speed the frictional force of down-hole cable and weight linear meter; How developing thus and can sustain several times of cables to five km cables deadweights, is the primary key technical problem that solves.First cable can not be meticulous; In order enough electric energy to be provided for the down-hole collector and to ensure its communication ability, the communications cable is at least two cores and can not be meticulous, and lead is meticulous; Line loss is excessive, and long-range transmission of electric energy of several kms and transfer of data just are difficult to realize technically.And the meticulous pulling force that it bears of cable is just big inadequately, just can not sustain the gravity of a few km cables and collector and weight linear meter; It two is that cable can not be thick excessively, and cable is thick under high pressure deformation can to take place, and when the cable band that connects the electronics collector is pressed into well, adopts the via hole slipper seal just to be difficult to realize high pressure sealing; It three is that counterweight is wanted suitably, and cable is thick, and sectional area is just big, under down-hole high pressure; The sectional area of cable can cause a rising buoyancy to down-hole collector and weight linear meter, and the bigger buoyancy that is under high pressure produced in line footpath is big more, and line footpath one regularly; Collector is sunk just must strengthen counterweight; Will increase the volume of weight linear meter and the bearing capacity of cable and strengthen counterweight, so just need increase cable pull again, just can only increase the line footpath when material is confirmed.This shows, adopt wired direct reading test mode, cable is crossed and slightly or meticulous is all had problems.In the actual Test Application in oil field, the cable footpath that wired direct reading test engineering is used is about 5mm～6mm at present, and outer is the many sheaths that the steel wire stranding is processed; Because of cable diameter is bigger, counterweight is generally all more than 100 kilograms, and this test mode is because the site operation operation is very complicated; Limited by hole condition, promptly well presses big more counterweight big more, and the down-hole collector is difficult to; Engineering cost is very high, and the site operation personnel is dangerous and labour intensity is big, and operating efficiency is low; So reality is seldom used, especially can not adapt to the test of high-pressure well and horizontal well

During the oil field formation testing is tested at home simultaneously; In most cases be to adopt steel wire to connect collector and weight linear meter; Rely on gravity collector to be sent into the down-hole, store in the down-hole after the image data, treat that pressure gauge and thermometer propose ground and handle the acquisition downhole data again through the well head slipper seal.When the hole condition conditions permit, formation testing test also can be adopted an electronic pressure gauge and thermometer to link to each other with the communications cable to carry out real-time wired direct-reading collecting test at the bottom of the lower going-into-well.The practical implementation method is to connect electron temperature and pressure acquisition device and weight linear meter to the cable of making sheath with many wire rope; Utilize gravity to pass through well head sliding sealing device and the stifled cable deformation gap of high-pressure pump injection stop-leak compound benefit; Band is pressed collector is sent into the down-hole, accomplishes thus and obtains the test data that gather the down-hole in real time.The shortcoming of this method is to obtain the hysteresis data, misses the chance of obtaining achievement easily, needs frequent rising to obtain needed data; Employ construction team and vehicle arrangement operation often; The accumulative total expense is high, and operating efficiency is very low, can not adapt to China oil field and bring in a well in a large number every year; Particularly the operation of horizontal well increases year by year, to testing efficiency require increasingly high.Obviously, this method can not be inserted collector in the horizontal well, so can not be used for the test of oilfield horizontal well.

The specific embodiment

Embodiment: shown in Fig. 1-8; It is for a kind of embodiment who is used for the downhole parameters direct reading test all-in-one of oil field vertical shaft and horizontal well of the utility model; Be mainly used in the test of oil field vertical shaft downhole parameters, and comprise that little power consumption collector 20, the little power consumption collector 20 of traction that fiber cable 10, an end link to each other with fiber cable 10 pass through the wireless treating apparatus 50 that the oil pipe crawl device of horizontal pipe, the Operating Pressure back pressure formula well head dynamic sealing device 30 that is arranged on well head production tree 1 top, the automatic control winch 40 that is positioned at the well aluminium hydraulic pressed connecting pipe 35 of Operating Pressure back pressure formula well head dynamic sealing device 30 belows, links to each other with the other end of fiber cable 10 and rest on the ground and wireless remote are controlled automatic control winch 40.Likewise, also can adopt wired mode to control the automatic control winch, also can realize the utility model purpose.

Like Fig. 2, fiber cable 10 is extraordinary ultra-fine ultralight ultra high strength fiber cable, and it comprises three transmission lines 15, intersects four Gent kind fibers 16 of stranded setting and the sheath 17 that transmission line 15 and special fibre 16 are coated with transmission line 15.Wherein every transmission line 15 includes the core body 18 that is positioned at it, and core body 18 is silver coated to improve electric conductivity.Transmission line 15 all adopts perfluoroalkoxy resin (PFA) insulation with sheath 17, and wherein the diameter of transmission line 15 is less than the diameter of sheath 17, and the diameter of sheath 17 is then less than 2mm.Fiber cable 10 load-bearing are greater than 100kg, deadweight 5～7kg/1000m, and impedance is less than 500 Ω/1000m.Guarantee that thus fiber cable is ultra-fine, avoid buoyancy too big, thereby influence the sinking of weight linear meter; And solid light again, be fit to long-range communications capabilities, Low ESR; Undistorted through three heart yearn signals; Abandoned traditional power carrier signal, converted data signal to, efficiently solved contradiction through current analog signal.Existing km fiber cable weighs 170 kilograms; And the fiber cable km of the utility model is less than 10 kilograms; And hundred kilograms of load-bearing 1-2; Have strong, the low line loss of in light weight, stretching resistance, high temperature resistant, corrosion-resistant, with distinguishing features such as environment is affine, can reduce the tension strength of communication fiber cable deadweight and counterweight and increased fiber cable simultaneously significantly.

Little power consumption collector 20 is used for measuring well downforce and temperature parameter and passes through fiber cable 10 and send in real time; Owing to need the 5000m long-distance transmissions; The minimum way of loss of signal is to adopt current delivery; But current delivery is separated timing at far-end and is had loss, and the precision of data just is difficult to meet the demands.And the distortionless way of 5000m remote transmission signal is to adopt Digital Transmission, but communication means such as 485 or CAN bus commonly used all can not directly be implemented the long Distance Transmission of 5000m.Therefore adopted the method for self-defined communications protocol, little power consumption collector 20 adopts the current system outputting data signals, and current value is divided into several sections, the number that each section representative is different, as: with 1～2.5mA representative " 0 ", with 3.5～6mA represent " 1 "; Digital parsing work is accomplished by ground demodulation analysis appearance.Its parameter is specific as follows: power consumption is less than 4mA; Cylindrical, diameter is 20mm, high 150mm; Weight is 100 grams; Power supply: 5～24VDC; Be output as 1～6mA; Range: temperature-50 ℃～150 ℃, pressure: 0～60MPa.

With reference to figure 1; And combine shown in Fig. 3-4; Operating Pressure back pressure formula well head dynamic sealing device 30 comprises the upper and lower slideway of the via hole that allows fiber cable 10 to pass 31,32, be arranged on upper and lower slideway 31,32 1 sides of via hole and lean on well to press the vigor storehouse 33 of injecting packing grease, be arranged in the vigor storehouse 33 positioning inductors that can well be pressed big thrust piston 334, be arranged on thrust piston 334 front ends, be arranged on vigor storehouse 33 afterbodys and with well press introducing vigor storehouse 33 high-pressure conduit 36, be used for security control high pressure needle valve, be arranged on the upper and lower slideway of via hole 31, the transition passage 34 between 32, the well aluminium hydraulic pressed connecting pipe 35 that is set in via hole glide path 32 outsides, the end other end that links to each other with well aluminium hydraulic pressed connecting pipe 35 and then manage 37 with the high-pressure conduit 36 in vigor storehouse 33 and the counterweight prolongation that links to each other with well aluminium hydraulic pressed connecting pipe 35.Wherein prior art adopts the mode of high-pressure pump, the mode that the utility model then adopts well to press, and cost simple in structure is low.Vigor storehouse 33 comprises container cavity 330 of accommodating stop-leak compound and the warehouse entry mouth 332 that is used to add stop-leak compound.Wherein via hole sliding way 31 is provided with locking wire knob 310, and transition passage 34 is provided with the adapter cavity 340 that is connected with container cavity 330, and stop-leak compound enters in the upper and lower slideway 31,32 of via hole through this adapter cavity 340 thus.Thrust piston 334 is a tail end near high-pressure conduit 36 1 sides promptly for the big little structure of head end of tail end, is head end near adapter cavity 340 1 sides, and the well that makes the thrust that promotes thrust piston amplify at least 1.2 times is thus pressed.

During work, fiber cable 10 connects little power consumption collector 20 and weight linear meter, utilizes gravity to pass through the upper and lower slideway 31,32 of via hole of well head 1, and band is pressed little power consumption collector 20 is sent into the down-hole.Fiber cable 10 will continue to pass through the upper and lower slideway 31,32 of via hole; Must be gapped between slideway and the fiber cable 10; On slideway, constantly add stop-leak compound in order to seal with 10 needs of lubricant fiber cable; In order to reach the effect of sealing chute, the dynamics of replenishing stop-leak compound must be greater than the pressure of well head, and promptly 1.2 times well is pressed.

Then Operating Pressure back pressure formula well head dynamic sealing device is installed to the top of well head production tree 1; Open little power consumption and gather the valve of 20 devices turnover oil well; Well is pressed at first can get into vigor storehouse 33 through high-pressure conduit 36, and the well that the little structure of thrust piston 334 tail major parts makes thrust amplify 1.2 times is pressed, and thrust piston 334 pushes stop-leak compound in the adapter cavity 340; Part stop-leak compound moves towards the down-hole through the fiber cable deformation gap of via hole glide path 32 downwards; And down-hole pressure also the fiber cable deformation gap through via hole glide path 32 upwards push away stop-leak compound and move towards the antagonism mutually in slideway of 340, two bursts of motive forces of adapter cavity because downward motive force is always big than the motive force that makes progress; The stop-leak compound viscosity is very big again, gets into via hole sliding way 31 so down-hole pressure can not pass via hole glide path 32.Certainly downward motive force is only big 1.2 times than motive force upwards again, and calculating can know that owing to the length of slideway and the effect of stop-leak compound viscosity downward motive force also can not be passed via hole glide path 32 and got into oil wells.Another that comes out from the vigor storehouse simultaneously partly stop-leak compound upwards moves towards beyond the via hole sliding way 31 through the fiber cable gap of via hole sliding way 31; Calculating can know because the length of slideway and the effect of stop-leak compound viscosity; When the pressure of 30MPa, the stop-leak compound that upwards promotes can not pass via hole sliding way 31.Hence one can see that, slide in the oil well process at fiber cable 10, via hole glide path 32 be rely on well to press to promote that stop-leak compound is sealed well head pressure and the well head pressure size irrelevant.Via hole sliding way 31 is to seal stop-leak compound by the viscosity of length of tightening up via hole and slideway and stop-leak compound, has sealed the well pressure exactly and sealed stop-leak compound.Under high pressure deformation can take place in fiber cable 10 in via hole sliding way 31; Because fiber cable 10 is a software, the end pressure small deformation is just little on the via hole sliding way 31, and 31 times end pressure large deformation of via hole sliding way will be big; So the section fibre cable in via hole sliding way 31 is a upper-wide lower-thin state; Fiber cable can produce the strength that upwards promotes fiber cable like this, but this thrust is less relatively, can eliminate through counterweight.The stop-leak compound of the utility model device is the vacuum silicone grease of heatproof-50 ℃～200 ℃.
