Technical field
Oil extraction in oil field device field is the utility model is related to, more particularly to a kind of specialty is entered for oil field using sliding sleeve switch
The downhole testing equipment of the oil-producing well delaminating pressure testing of row separate zone production, i.e., a kind of oil field is with across the supporting mechanism every measuring cell.
Background technology
At present, traditional oil-producing well delaminating pressure testing mode is by wireline operation multiple switching sliding sleeve, that is, closes purpose and survey
All sliding sleeves outside layer are tried, wait build-up of fluid to ask for target zone strata pressure afterwards.After the layer is completed, then pass through cable
This layer of sliding sleeve is closed in rope operation, opens the pressure measurement operation that other target zones enter next link.Therefore, traditional delaminating pressure testing side
Formula has the following disadvantages：(1) during pressure measurement process, it is necessary to closing well, influence oil well production；(2) during target zone pressure measurement, it can not be judged
Whether the sliding sleeve of its layer position closes in place, is easily caused pressure measurement data distortion；(3) recover because pressure reverts to free surface, well storage
Effect is very big, if wanting to obtain qualified data, it is necessary to which a couple of days did not waited the closed-in time by several months；(4) if want to explain mono-layer osmotic rate,
The parameters such as skin factor need individual layer yield data to be fitted, then need individual layer first to seek Recovery, and multilayer pressure measurement work flow needs
Toggle, process is complicated, cumbersome；(5) closed-in time is grown, and influences oily well yield, reduces the cumulative production of oil well,
Larger economic loss can be caused.
Due to case above, traditional closing well delaminating pressure testing well testing is the method that Oilfield Decision-making department pole is reluctant to use.Cause
How this, find an urgent demand simple, economic, that efficiently delaminating pressure testing well-logging method produces as oil field development already.And
At present also it is a kind of dedicated for oil field across the supporting mechanism every measuring cell.

The supporting mechanism regulation motor 500 being connected with cable head assembly 400, top are provided with top installation cell body 100
Installation cell body 100 lower end is provided with the supporting mechanism 600 being connected with the output shaft of supporting mechanism regulation motor 500 510, supports machine
Structure 600 can be collapsed or opened.
Induction controller 700 is provided with top installation cell body 100, and induction controller 700 is controlling support machine
Structure 600 collapses or opens and whether in place to sense supporting mechanism 600.Specifically, supporting mechanism 600 includes being provided at circumferentially spaced
Support arm 610 on the output shaft 510 of supporting mechanism regulation motor 500, each support arm 610 is by supporting arm base 620 and again
Position torsion spring 630 is connected with the end of output shaft 510 of supporting mechanism regulation motor 500.The bottom outer face of support arm 610 is oblique
Spigot surface 611, the lower outside of support arm 610 is provided with spacing groove face 612, the groove top both ends of spacing groove face 612 are respectively
Transition plane 612a, 612b.
Induction controller 700 include on a pair output shafts 510 for being separately positioned on supporting mechanism regulation motor 500 and
Docking location sensor 710,720 in top installation cell body 100.The top of output shaft 510 set of supporting mechanism regulation motor 500
Provided with spring 511, the end set of output shaft 510 of supporting mechanism regulation motor 500 has a locating piece pin 512, on supporting arm base 620
It is provided with the keyway 621 coordinated with locating piece pin 512.The end of output shaft 510 of supporting mechanism regulation motor 500 is additionally provided with drive
The cam pack 513 that support arm 610 is collapsed or opened is moved, thoughts are also set up on the output shaft 510 of supporting mechanism regulation motor 500
Answer the turn-sensitive device 514 of the turned position of cam pack 513.
Operation principle of the present utility model is as follows：
The specific course of work of the present utility model includes the docking of supporting mechanism：
Instrument is transferred by cable car, when instrument reaches destination layer position, supporting mechanism is made by ground far-end control device
Regulation motor 500 works, and the folding and unfolding process of support arm 610：When motor turns clockwise, power is driven by output shaft 510
Cam pack 513 and docking magnet steel seat 515 rotate, and when the position of the fulcrum of cam pack 513 is in a high position, support arm 610 is simultaneously
Collapse, when the fulcrum of cam pack 513 is in low level, support arm 610 is decontroled simultaneously.The inductive output axle 510 of turn-sensitive device 514
Rotating cycle, ground far-end control device is then transferred data to, the rotation of main shaft is controlled by ground far-end control device, with
Reach folding and unfolding purpose.Continue to transfer instrument, (such as Fig. 3 institutes when support arm 610 is continuously across oil pipe 1 and tubing coupling junction
Show) because the effect of reduction torsion spring 630, the subtended angle of support arm 610 can manage with transition plane 612a, 612b and oblique spigot surface 611
The change in footpath and magnify or reduce.When support arm 610 is by oil pipe 1 and box cupling junction position, the transition of support arm 610 is put down
Face 612a contacts with tube inner wall above box cupling, (such as Fig. 4 institutes when instrument continues traveling downwardly oil pipe 1 and box cupling junction position
Show), the oblique spigot surface 611 of support arm 610 contacts with tube inner wall below box cupling, and instrument goes downwards to oil pipe 1 and box cupling junction
During position (as shown in Figure 5), because the transition plane 612b of support arm 610 contacts with tube inner wall, now transition plane 612a
Height dimension residing for domatic low level is less than pipe aperture, and spacing groove face 612 will not be caused to set the section of the oil pipe below box cupling
On.
Continue lower section instrument, when support arm 610 reach 2 position of sliding sleeve switch when (as shown in Figure 6), oblique spigot surface 611 and
The contact of sliding sleeve top connection main body inner wall is pressurized and shunk.Instrument continues traveling downwardly position shown in Fig. 7, because reduction torsion spring 630
Elastic force effect support arm 610 subtended angle increase, as instrument continues traveling downwardly, the subtended angle of support arm 610 continues to increase, until transition plane
612b contacts (as shown in Figure 8) with the bottom land of sliding sleeve switch 2, now spacing groove face 612 just with the longer channel section 2a of sliding sleeve switch 2
Contact.Instrument continues traveling downwardly, and under gravity, spring 511 is pressurized, and instrument moves down, when locating piece pin 512 contacts support arm
Seat 620 on keyway 621 when, docking location sensor 710,720 centerings (as shown in Figure 9), instrument will pass through single-core cable general
Docking pass signal is transferred to ground far-end control device.
On the descending path of instrument, across only reaching sliding sleeve switch position as shown in Figure 9 every measuring cell support arm 610
When, support arm 610 can just dock success.And at downlink path other positions, the transition plane 612a groove high points of support arm
Contacted with inside pipe wall, and oblique spigot surface 611 is passed through front platform rank, after oblique spigot surface 611 is by platform rank, transition is put down
Face 612b will contact with inside pipe wall, so that the transition plane 612a low spots height dimension of support arm 610 is less than front platform
Rank radius of circle, the spacing groove face 612 of support arm will not be caused to be sitting on the platform rank of front.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
