The specific embodiment
Fig. 1 shows by wirerope 5 and is suspended on the tool tubular column 1 in well 4.Tool tubular column 1 also can utilize coil pipe or be draped by a part that becomes drill string.Shown well comprises sleeve pipe 14, but tool tubular column 1 also can be used in bare hole.
Tool tubular column 1 extends longitudinally and at least comprises the first tool tubular column part 2 and the second tool tubular column part 3.The first end 200 of the first tubing string part 2 and the first end 400 of the second tubing string part 3 connect via the Connection Element 6 longitudinally be configured between two tubing string parts 2,3.Illustrated in dashed lines in Fig. 1 the part of first end 200 of the first tubing string part how through Connection Element 6, to extend in the first end 400 of the second tubing string part.
With reference to Fig. 2, hereinafter will be described in more detail being connected between the first tubing string part 2 and the second tubing string part 3 shown in Fig. 1.For purpose clearly, the part of Connection Element 6 and the second tubing string part 3 is penetratingly cut and is illustrated with sectional view.
In first end 400, the second tubing string part 3 comprises the applicable protuberance 27 of the first tubing string part 2 and the eyelet 47 of Connection Element 6 received.This eyelet by the second tubing string part 3 be applicable to the threaded portion 48 be connected with the threaded portion 61 of Connection Element 6 around.At one end, eyelet 47 is defined by the face 401 that comprises a plurality of holes 42,43,44 that are applicable to receiving conduit coupling 22,23,24, as shown in Fig. 3 a and 3b.Face 401 also comprises the hole 46 and the applicable electrical connector be connected with plug 21 that is applicable to receiving directing pin 26, and for example socket 41, as shown in Fig. 3 a and 3b.
The general layout of outstanding conduit coupling 22,23,24, directing pin 26 and plug 21 is shown in Fig. 3 a, and the layout of the hole 42,43,44 of coupling and socket 41 is shown in Fig. 3 b.Conduit coupling 22,23,24 is connected with corresponding fluids passage 220,240 fluids in the first tubing string part, and hole 42,43,44 is communicated with corresponding fluids passage 420,440 fluids in the second tubing string part 3.By conduit coupling 22,23,24 is configured in respective aperture 42,43,44, the fluid passage in fluid communication of the fluid passage 220,240 of the first tubing string part and the second tubing string part.In a similar manner, plug 21 and socket 41 provide the electrical connection between the first and second tubing string parts.
As shown in Fig. 3 a and 3b, the conduit coupling 22,23,24 of the first tubing string part 2 and the respective aperture 42,43,44 in the second tubing string part 3 configure prejudicially about central axis 10.By at least one in conduit coupling 22,23,24 is configured in to a distance apart from central axis prejudicially, prevented that the first tubing string part 2 and the second tubing string part 3 from rotating mutually around central axis 10.One or more conduit couplings thereby have during both are used in down-hole tubing string part fixing additional function relative to each other at the assembling of tubing string part and tool tubular column.
Directing pin 26 is extended away from end face 201 more than conduit coupling.At the assembly process of the first and second tubing strings parts, directing pin 26 thereby patchhole 46 are with the control group process of assembling and prevent due to relative to each other rotation or the angled damage caused of tubing string part.If the tubing string part is not correctly alignment during assembly and disassembly, plug and socket and conduit coupling may be crooked or impaired.When directing pin 26 is configured in hole 46 when interior at least in part, two tubing strings partly keep relative to each other almost parallel.By directing pin is set, prevented from when the first and second tubing string parts from connecting between the two tilting a little.This inclination a little when connecting itself may cause that conduit coupling leaks, thereby its reason or be conduit coupling as the integral part of an end of tubing string part crooked and thereby separate a little to form and fracture, or be as the conduit coupling of unitary part tilted in hole.
Conduit coupling can be that the integral part of tubing string part or they can be independent pipelines.Conduit coupling configurable in a tubing string part and another conduit coupling configurable in another tubing string part, make when by the tubing string part in conjunction with the time, conduit coupling plays guiding piece in assembling process.
Fig. 5 shows the downhole tractor 81 as the part of tool tubular column 1, and wherein two tubing string parts the 2, the 3rd, utilize above-mentioned Connection Element 6 to assemble.Downhole tractor hangs and provides power by the wirerope 5 be connected with downhole tractor through top connector 71.Downhole tractor 81 comprises electronic equipment section 72, motor 73, hydraulic pump 74 and two wheel sections 80 that driven by hydraulic means.The wheel section is communicated with hydraulic pump 74 fluids and also can be expressed as for advance the driver element 80 of downhole tractor and tool tubular column in well.Downhole tractor can be connected with the downhole tool 75 of one or more operations that is also the part of tool tubular column 1.The instrument of this generic operation can be key-shaped tool that the valve in percussion tool (stroker tool), unlatching or the closed-in well of axial force is provided in one or many impacts, the orientation tool such as casing collar locator (CCL) (CCL), milling tool, boring bar tool etc.
Two tubing string parts 2, the 3 for example connections between two wheel sections 80 of downhole tractor can be used for transmitting fluid (multiple) and/or electric power.Electric power can be passed to the first tubing string part and be passed to the tubing string part of back via plug 21 and socket 41 from wirerope 5.Conduit coupling 22 can be used for connecting to be provided pressure fluid to the wheel section so that the outstanding fluid passage of wheel arm 76 of installing pivotally from hydraulic pump 74.Conduit coupling 24 can be used for connecting to be provided pressure fluid to the wheel section so that be arranged on the fluid passage that the wheel 77 of wheel arm 76 is rotated in a clockwise direction from hydraulic pump 74.Conduit coupling 23 can be used for connecting to be provided pressure fluid to the wheel section so that be arranged on the fluid passage that the wheel 77 of wheel arm 76 rotates in the counterclockwise direction from hydraulic pump 74.Conduit coupling 25 and hole 45 can be used for connecting needle provides the fluid passage of backward channel to the fluid that is supplied to the wheel section.
Fluid or well fluids refer to the fluid of any kind that may exist in the downhole oil gas well, such as natural gas, oil, greasy filth, crude oil, water etc.Gas refers to the gas componant of any kind existed in well, completion or naked hole, and oil refers to the oil component of any kind, such as crude oil, containing flow of oil etc.Therefore, these fluids of gas, oil and water can comprise other element or the material that is different from respectively gas, oil and/or water.
Rotatably connect and refer to, the first rotatable object is connected with the second object, make the first object can with rotate when the second object is connected and the first and second objects between be connected to during the first object rotates with respect to the second object and be maintained.Sleeve pipe refers to about the pipe of any kind of using in down-hole of oil or natural gas production, pipeline, pipe fitting, lining, tubing string etc.
In the situation that instrument can not all sink in sleeve pipe, can instrument be pushed to the appropriate location in well always with downhole tractor.Downhole tractor is to promote or to pull in down-hole the driven tool of any kind of instrument, for example Well Tractor
.
Although above in conjunction with the preferred embodiments of the present invention, described the present invention, it is evident that to those skilled in the art, under the prerequisite of the present invention do not broken away from as limited by following claim, it is contemplated that several remodeling.
