In some respects, the present invention is exactly the 3rd, 090, the modification of No. 233 described systems of United States Patent (USP).Last system mechanically pushes and pulls out a harder measurement component, but not mentioned temperature sensing component such as thermocouple move up and down with can doing long distance in well in this system.But the applicant has been found that the certain combination that utilizes some parts measures in can be between the subsurface formations tectonic province, and relatively say so between the subsurface formations tectonic province very dark, very long, be awfully hot.This just need be a long measurement component conduit, an available strip metal
The heat-staple telemetry cable of dress come the sensing element, one of the temperature-sensitive signal of remote measurement electricity be connected on below the sensing element, the flexible heavy parts that adds is in the same place with a unit construction that can coil telemetry cable; Also need to make these parts to have multiple physical characteristic and chemical characteristic, and these characteristics all are inter-related.In addition, the applicant notices with the aforementioned subsurface method of temperature of measuring in well and compares, several parts of explanation make up mutually now, especially along each point measurement between the subsurface formations tectonic province do not increase computer printout output fast the people more than the scanning be the time, the measurement that can make real equalization temperature is very useful.On the contrary, in order to obtain such thermograph, last method needs continuous duty, postpones operation several days or several week in the well.
Thereby, the objective of the invention is in well or on every side, length greater than 60 meters, the degree of depth greater than 600 meters and awfully hot, when measuring temperature in needing between pyrometric subsurface formations tectonic province, provide a kind of short-cut method of handling and/or operating well.According to long and straight measurement component conduit of the present invention in the face of land extends to well the tested interval, a flexible temperature sensing component that adds heavy parts, an electricity, a cable and the parts that can coil and can emit telemetry cable that can coil, heat-staple, that the remote measurement sensing element signal of telecommunication is used all must be provided with and will be connected to each other, can be stretching the sweep of telemetry cable so that act on the gravitation that adds on the heavy parts; Can also in the measurement component conduit, down drag temperature sensing component and telemetry cable, when cable is crooked and stretching, cable not produced tangible cold working.Operation board makes temperature sensing component dragged by gravity downwards between measurement zone around parts, and the wearing or featuring stage armour telemetry cable is wound on the roller bearing it is upwards drawn.Control the speed of this motion, so that from the signal of telecommunication of temperature sensing unit remote measurement temperature-sensitive.And this unit actual temperature and temperature of measuring in tested interval in the scope that requires are balances.With the corresponding temperature of the remote measurement sensing signal of telecommunication with the temperature of the corresponding survey mark in temperature sensing component position indication is arranged all.The length of telemetry cable of coiling is not corresponding on the position of sensing element and the coiling parts.
Explain the present invention in more detail referring now to accompanying drawing.Wherein:
Fig. 1 is mounted in the system schematic of the present invention in the small-sized well, or the schematic diagram that buries a cement sleeve pipe is given on the next door of measurement component conduit in well.
Fig. 2 is the section amplification figure of that small-sized well.
Fig. 3 is the circuit block diagram of coiling operation of components in the control chart 1.
Fig. 4 is the another kind of schematic diagram of arranging.Measurement component conduit of the present invention promptly can be used as the small-sized well use among the figure, and the guiding tubing string that also can be used as heater cable uses.
Fig. 1 illustrates a glance well thorax 1, and a sleeve pipe 2 is installed in the well thorax, and waters with cement 3.For example, such well can be a glance temperature observation well.Heater of operation makes the oil circulation of viscous in well, or makes the coagulation band of a part of oil close-burning of oily reservoir with formation sand shape, or forms an electrode, and electric current is flow on this electrode by oily reservoir or similar with it oil reservoir.
An elongated measurement component conduit 4 extends downwards along sleeve pipe 2, enters and by tested " well logging " interval 2.Conduit 4 preferably can coil and be bonded on the pipe racks, for example, on the sleeve pipe 2, becomes one with the cement pouring on every side, for example with cement 3 pourings.Cement encases sleeve pipe to be guaranteed full and uniformly heat is spread out of or imports into from stratigraphic structure, also avoids liquid to flow out in the sleeve pipe or flows into.The most handy sealing device 5 in the bottom of measurement component conduit is sealed tightly.For example, sealing device 5 can be pipe cap, stopper, plug, cement block or similar item.
In Fig. 2, draw clearlyer by a flexible heavy parts or the hot joint 7 of 6, thermocouples of title " flexible sinker rod " and the telemetry cable 8(of a remote measurement thermocouple signal of telecommunication of adding) temperature sensing component formed is assemblied in the measurement component conduit 4.What this was flexible adds heavy parts or claims flexible sinker rod 6 to be made up of a string sinker pearl (being short and small weight) 6A, this string sinker pearl is connected with flexible wire 6B on its slip around ground, and 6C makes them separated from each other with the pearl bolt, and the pearl bolt is connected on the flexible wire 6B flexibly.
The telemetry cable 8 that adopts preferably formed by thermocouple wire or by call wire in order to send the sensing signal of telecommunication of exporting from the hot joint of thermocouple, and they have similar pyroelecthc properties, and are suitable for thermometric solid material insulation by nonconducting heat stability.As those people that expertly grasp this gate technique known, though thermocouple at first develops in high temperature measurement, for measuring lower temperature range, thermocouple is competed mutually with resistance thermometer and various turgor pressure miniature thermometer now; For measuring very high temperature range, it is competed mutually with method of radiating.
In tested interval, the position of temperature sensing component 7 is corresponding around the degree that parts 9 are not coiled from cable hank with cable 8.Cable hank is being controlled the speed that temperature sensing component moves around Parts Controller 10 in tested interval.
Usually, these controls being set is in order to adjust the speed and the torque of coiling drive motor.The speed of motion is variable, and preferably per second is 8 to 5000 centimetres.Certainly, pine around speed should keep enough slowly, to avoid telemetry cable spirally-wound or knotting.The most suitable thermometric recording rate is the about 6 English inch of per minute, and promptly crossing between 90 meters long subsurface formations tectonic province approximately needs 10 hours.Temperature-sensing electrical signal is sent to measures indicating member (for example using the mercury slip ring assembly).
That the measurement component conduit preferably can coil continuously, stainless steel tube, preferably internal diameter is 0.8 to 1.4 centimetre, No. 316 stainless steels preferably, or be equivalent to stainless steel No. 316.The most handy binding method of measurement component conduit ties up on the outer wall or pipe racks of pipeline.The colligation point should be positioned at the maximum gauge place of this pipe racks, for example, at the neck place, so that the measurement component conduit is straight as far as possible, especially will note avoiding this measurement component conduit colligation is had the place of spiral coil around sleeve pipe or pipeline.
Used sinker pearl in the conduit of optimum size, as excellent pearl 6A, preferably external diameter is about 0.5 to 1.1 centimetre, length is about 2.5 to 20 centimetres.In such structure, flexible sinker line 6B is a flexible wire preferably, as 0.15 centimetre aircraft cord wire line, the preferably a bit of tubule of pearl bolt 6C, 0.30 centimetre of tubule for example, each excellent pearl is at a distance of about 1.25 centimetres, they securely bolt on the sinker line.
Usually, by flexible heavy parts such as flexible sinker rod 6, temperature sensing component such as thermocouple junction 7, a strip metal of adding
The telemetry cable 8 of dress and coiling telemetry cable parts should have multiple physics and chemical characteristic as a kind of unit construction that coils parts 9 compositions, and be equipped with interrelatedly, so that the gravity that acts on the sinker rod can drag sensing element downwards through tested interval, simultaneously by the roller bearing turning handle bending of coiling parts cable section stretching.By many times testing in the well, the applicant finds to adopt the parts of following specification just can make that such structure is relevant with multifrequency nature to become a typical example, be the measurement component conduit by internal diameter be that 0.9 centimetre, external diameter are formed by 1.25 centimetres No. 316 stainless steel tubes, flexible sinker rod is made up of 80 excellent pearls, 0.6 centimetre of the long 2 English inch of each excellent pearl, diameter (being about 5 meters to provide gross mass to be about 0.9 kilogram, total length).Surveying the used cable of the remote sensing temperature signal of telecommunication is a steel band
Dress, diameter are 0.15 centimetre cable, and it is coiled on the coiling parts of roller bearing that diameter is about 50 centimetres.
In view of the such combination of parts, the cold working of telemetry cable (because bending of cable on the coiling parts roller bearing) approximately has only 0.3%.The deviation of measurement component conduit and general vertical line is (owing to coiled coil or backward rotation there, as " dog leg ") actual be zero, temperature sensing component is not only along with gravity moves downward (the not motion-impeding sign owing to rub) smoothly, and when with the roller bearing coiling of coiling parts this system being risen, the obvious load that produces owing to friction does not appear.Test many times shows the combination that these parts are same, and used measurement component conduit and vertical line are when having some spiral deviations, perhaps, although move downward is that other people is satisfied, but because frictional force can produce load on telemetry cable, this load value is also bigger than its tensile strength when rising in this system.
Fig. 3 shows the main circuit parts that are used for control cables coiling parts such as Fig. 1 parts 9.As the people of this gate technique on top of can find out, all these parts of indicating can both can buy.A data logger 20 is set receives the degree of depth and temperature signal, and give well logging speed and directional control circuit 21 control instruction of coding, then trigger electromotor control circuit 22, come the sender to giving the motor 23 that coils parts with rate signal.The degree that degree of depth decoder 24 does not coil according to telemetry cable 8 draws the index signal of thermocouple location.Depth signal 26 binary-coded decimal is converted to hexadecimal depth signal in converter 25 then, and this signal is sent into data logger 20 with the temperature signal 27 from thermocouple.
This method may have special advantage when heated underground interval heating-up temperature is higher.The measurement component conduit runs through whole tested interval and extends near the used heater.When operate heater makes its temperature to giving fixed heating-up temperature when raising, the logging speed of adjusting temperature sensing component makes it cross this interval with fast speed, so that detected the generation of arbitrary heat generating spot along this interval each point before any tangible injury takes place.When the temperature of heater arrives or when giving fixed heating-up temperature, logging speed can be reduced to keeps thermally equilibrated speed between sensing element and the well bore temperature.
In radio communication or personal monitoring all difficulty or even the mountain area that can not realize, the application of telephone-type modem 28 also has many special advantages.Native system can be used for central authorities' control of a large amount of thermal sprayer of field work.
According to principle of the present invention, Fig. 4 illustrates the another kind arrangement of measurement component conductor topology and application.System shown in Figure 4 is used for the interval down longways specific device that at high temperature evenly heats.
As shown in Figure 4, measurement component conduit 40 is used as the guiding tubing string use of heater cable.Because the weight pulling guiding tubing string of the sinker rod 44 of guiding below the tubing string, enter well inner sleeve 43 through the inside of resting barrels 42 from guiding tubing string coiling device 41.Coiling device 41 is to be driven by an aeroplane motor.A pair of heater cable 45 wherein every cable all is that metal core wire, its outsourcing mineral insulation, outermost layer by a conduction is stainless steel belt
Dress is formed.This is to heater cable 45 and pair of metal
The feed cable 46 of dress, mineral insulation is connected.Be heated the interval for heater cable is extended to through sleeve pipe, all on the cable guide 47 that rotates, this guider 47 is contained on the fixing cylinder 42 total length of the distinct cable of this two couple, and the guiding tubing string of tubulose extends downwards through resting barrel 42.Heater cable is connected on the terminal brace 48, and this brace is connected with the guiding tubing string again.Enter sleeve pipe along with the conduit 40 that leads moves downward, follow the feed cable circle after the heater cable circle and also move downward, and enter sleeve pipe with the form of spiral winding, this spiral winding has suitable wavelengths L.When guiding tubing string 40 moves downward when finishing, the spiral winding of cable 45 is outwards pressed to the inwall of sleeve pipe 43, in the weight of these coils be not all be exactly wherein major part supporting by the frictional force between they and the internal surface of sleeve pipe often.
In this arrangement according to this method, after the guiding tubing string that measurement component conduit of the present invention is formed entered sleeve pipe, it preferably hung on the hook of well head, and this hook is as hanging the continuous general hook of tube coupling band.If the pressure that produces in the sleeve pipe that contains the measurement component conduit is greater than atmospheric pressure, temperature sensing component of the present invention can enter sleeve pipe by a lubricating coupler, and this lubricating coupler is the same with lubricating coupler commonly used.Certainly, be provided with this lubricating coupler, the frictional force that produces by it can not stop temperature sensing component at the action of gravity downward motion.
