Abstract
The invention discloses an unblocking device of a cable logging instrument. The unblocking device comprises a ground instrument and an underground instrument which are connected by a salvage cable, wherein the underground instrument comprises a peristaltic crawler; a horse tap is fixed to the top of the peristaltic crawler; a plurality of cable through rings are arranged on the side surface of the peristaltic crawler. The unblocking device is simple in structure and convenient to operate. In use, unblocking can be finished in a short time without damaging the cable of the cable logging instrument, and then the problem that the cable logging instrument is blocked is solved.
Description
Technical field
The invention belongs to the auxiliary equipment in oil reservoir logging process, relate in particular to a kind of new instrument that can be to the unfreezing of wireline logging instrument.
Background technology
In the cable instrument during well logging in oil field, because some reasons such as the quality of drilling well hole condition (hole deviation is large, broken line hole condition), the quality (mud is thick, viscosity is large) of mud, wireline logging instrument time of staying in well are long or a plurality of reason cause the sticky card of wireline logging instrument (being mainly that cable is sticky is stuck on the borehole wall) cannot pull out in well.In this case, in order to guarantee that (1) wireline logging instrument can not damage, in (2) well, because of snapping in of logger, do not affect the further construction of this well, conventionally have to carry out punching salvaging.
It is the cable of having gone into the well by cutting off that punching is salvaged, fisher is gone into the well along cable together with drilling rod, wait after fisher blocks logger, by more than sections, drilling rod, carry, drilling rod is carried on the cable limit of disconnecting, limit, reaches the object that wireline logging instrument is the most at last salvaged well.Punching is salvaged and is had following shortcoming: the cable that (1) loss has been gone into the well; The chance card well depth of (2) 2000 meters, completing punching salvaging at least needs two day time, wastes time and energy; (3) bad instrument of fisher card; (4) block in the instrument salvaging process that does not live instrument or block and come off, secondary falls well; (5) logging tasks does not complete, and need to repeat logging tasks.In a word: it is to solve wireline logging instrument to meet the method that card is done something against one's will that punching is salvaged.
Summary of the invention
It is the technical problem in background technology that the present invention will solve, and a kind of wireline logging instrument stuck-releasing device is provided.
In order to address the above problem by the following technical solutions: a kind of wireline logging instrument stuck-releasing device, comprise ground instrument and downhole instrument, between ground instrument and downhole instrument, by salvaging cable, connect, downhole instrument comprises a wriggling crawl device, top at wriggling crawl device is fixed with halter, is provided with several wears cable loop in the side of wriggling crawl device.
Described ground instrument is for powering to downhole instrument and controlling downhole instrument action.
Wriggling crawl device is mainly saved by electronics from top to bottom and the joint of creeping forms, and halter is fixed on the top of electronics joint.
The side of wriggling crawl device is provided with uniformly at least two and wears cable loop.
The side of wriggling crawl device is provided with uniformly four and wears cable loop.
The present invention is simple in structure, convenient operation.In use procedure, can not destroy wireline logging instrument lead, and carry out at short notice unfreezing, thereby solve the problem that wireline logging instrument is met card.
Accompanying drawing explanation
Fig. 1 is the structural representation of ground instrument of the present invention.
Fig. 2 is the structural representation of downhole instrument of the present invention.
Fig. 3 is the process chart of going into the well of the present invention.
Fig. 4 is unfreezing process chart of the present invention.
The specific embodiment
As shown in Figure 1, a kind of wireline logging instrument stuck-releasing device, comprises ground instrument and downhole instrument, between ground instrument and downhole instrument, by salvaging cable, connects.Ground instrument is powered to downhole instrument by cable, the exercises of the information that ground instrument returns according to downhole instrument, control downhole instrument.
As shown in Figure 1, ground instrument comprises that housing, enclosure interior are provided with four layers of skeleton, and skeleton sets gradually control panel 1, power panel 2, pressure regulator case 3, transformer tank 4 from top to bottom.
As shown in Figure 2, downhole instrument comprises a wriggling crawl device 5, wriggling crawl device 5 is mainly comprised of electronics joint 5-1 and the joint 5-2 that creeps from top to bottom, halter 6 is fixed on the top of electronics joint 5-1, halter 6 is salvaged cable 10 and wriggling crawl device 5 for connecting, and is provided with four wears cable loop 7 in the side of wriggling crawl device.
Under the control of ground instrument, crawling type crawl device is a kind ofly can or claim tugger at the tractor of down-hole motion, can in open hole well, open one's arms and support between two parties to the borehole wall, also can alternately open one's arms support to the wriggling up and down of realization on the borehole wall in well.Crawling type crawl device bears a heavy burden (dragging 2000KG) up and down, at a slow speed (1 m/min) creep.
The course of work: as shown in Figure 3,4, wriggling crawl device 5 self is being salvaged under the control of cable 10, goes into the well along the cable 9 of meeting card wireline logging instrument 8 by wearing cable loop 7, does not destroy the cable of meeting card wireline logging instrument.Wriggling crawl device 5 is lower motionless in the situation that by gravity, and starting is at any time met card wireline logging instrument and seen whether unfreezing, this time-division three kinds of situation: a, unfreezing, and task completes, wriggling crawl device and meet card wireline logging instrument 8 and propose separately well head; B, not unfreezing, open the both arms 5-3 of wriggling crawl device, the cable of meeting card wireline logging instrument is forgotten about it in pressure in the central authorities of well, firing cable logger is seen whether unfreezing, if unfreezing, first starting is met on card wireline logging instrument 8 and is carried, then wriggling crawl device is regained on both arms 5-3 and carried, and completes unfreezing task; C, the also not unfreezing of both arms of opening wriggling crawl device, just control wriggling crawl device and creep up and down and realize unfreezing at sticky stuck point, repeats b process.
