Description
Technical field
The utility model relates to the technical field using logger to log well in drilling well, particularly a kind of device being used for unfreezing when reclaiming logger in cable process and meeting card.
Background technology
Due to the feature of wireline logging technique self, need first with the winch with cable and cylinder, the logger being connected to cable end piece to be sent into the shaft bottom of having bored, and then reclaim on cable and carry logger, in the process that logger is up, obtain well-log information.In the process that logger is up, in drilling well, frictional resistance is large, especially in hole angle or the larger position of azimuthal variation, can cause logger can not be up most probably, and then " meeting card " phenomenon occurs.Because the tensile strength of cable is limited, if go up portable cable by force, the pulling force above carried exceedes the maximum stretching resistance of cable, and cable will be pulled off, and causes logger to fall the accident in shaft bottom.When bore hole is logged well, putting forward to solve the accident that the logger occurred in process falls shaft bottom, mainly containing following two kinds of processing modes at present:
One, pull off cable, salvage well instrument;
During by logger carried by winch drive cable, on if to carry frictional resistance in process too large, or hole angle or azimuthal variation cause more greatly logger " meet card " can not up time, pull-up cable exceedes the tensile strength at cable " weakness " place by force, partially recycled to ground by more than cable " weakness ", the logger of the following part of cable " weakness " and connection falls into shaft bottom.Then the logger of fishing tool to shaft bottom is utilized again to salvage.Fishing can need a lot of time, and operating cost also can be very high.Especially in deep-well, make a trip and all need to spend more time during fishing, usually can select to abandon to salvage logger and the new well of sidetracking, the practicality of the method is poor.
Two, " Cut-and-thread fishing " method is adopted;
In most cases, wireline logging instrument upper carry in process there is " meet card " phenomenon time, adopt " Cut-and-thread fishing " operation.First fishing tool is connected to the bottom of drilling rod, again cable is penetrated the inside of every root drilling rod, then utilize drilling rod that the drilling tool with fishing tool is put into well until " meeting card " position, logger pins by fishing tool, then cable pulled off and reclaim all cables, finally trip out whole drilling tool thus reclaim logger.Adopt the method, the degree of depth of salvaging is in stuck point position instead of in shaft bottom, decrease the lost motion of each part in drilling well, but need to relate in whole operation process to cooperatively interact between multiple part, multiple operating personnel and just can complete, operating process is very loaded down with trivial details, and there is certain risk, more time-consuming than first method.
Utility model content

Detailed description of the invention
Below in conjunction with accompanying drawing, to above-mentioned being clearly and completely described with other technical characteristic and advantage of the utility model, obviously, described embodiment is only section Example of the present utility model, instead of whole embodiment.
Refer to shown in Fig. 1, the utility model proposes a kind of wireline logging release device, comprise haulage gear 10, the jarring controlling organization 20 be electrically connected with haulage gear 10 and bumper jar 6.More preferably, bumper jar 6 is mechanic jar or hydraulic shock device.
Jarring controlling organization 20 is connected by cable 5 with bumper jar 6, and haulage gear 10 draws or lower payout 5; Bumper jar 6 can produce jarring force downwards along the centerline direction of cable 5, and jarring controlling organization 20 controls the jarring force value of bumper jar 6 by cable 5; Cable 5 is connected for the logger 7 collecting shaft bottom data with outside via bumper jar 6.
In the present embodiment, logger 7 is fixedly connected on the lower end of bumper jar 6.Logging operation completes, and in the process reclaiming cable 5, logger 7 easily meets card in up process, makes bumper jar 6 produce jarring force, thus in the unfreezing of stuck point position.The utility model structure is simple and method of operating is simple, and dependable performance, salvages logger 7 again after avoiding cable 5 to break, save manpower, improve efficiency.
Further, refer to shown in Fig. 2, the frequency converter 3 that jarring controlling organization 20 comprises controller 2 and is electrically connected with controller 2, the output of frequency converter 3 is connected with cable 5, and controller 2 controls bumper jar 6 by frequency converter 3 and cable 5 successively and produces jarring force.Controller 2 controls the start and stop of bumper jar 6 by frequency converter 3, and is controlled the size of the jarring force of bumper jar 6 by the change of frequency of frequency converter 3, and the size of jarring force can according to circumstances regulate arbitrarily.
As the enforceable mode of one, haulage gear 10 comprises cylinder 4 and a motor 1, cylinder 4 for drum cable 5, the rotation of motor 1 index drum 4.More preferably, controller 2 is fixed on motor 1, and in order to compact overall structure, also can also be fixed on motor 1 by frequency converter 3, as shown in dotted line frame in Fig. 2, motor 1, controller 2 and frequency converter 3 are installed as a whole.In the present embodiment, haulage gear 10 is a hoister system.
As the enforceable mode of one, one end of cable 5 to be fixed on cylinder 4 and to be connected with the output of frequency converter 3, and the other end of cable 5 is free end, and cylinder 4 reels.In the present embodiment, adopt the cable of diameter 12mm.As the enforceable mode of another kind, common flexible strand breakdown cable 5 can also be adopted, and flexible strand can bear jarring force along its length, flexible strand is connected between the frequency converter 3 of rotation control mechanism 20 and bumper jar 6, and rotation control mechanism 20 also comprises the signal transmission device that between with logger 7, wireless telecommunications are connected.
More preferably, the output current value energy consecutive variations of frequency converter 3, the ascending consecutive variations of usual output current value, the jarring force value of such bumper jar 6 can become large gradually, until logger 7 is in the unfreezing of stuck point position.Jarring force will ensure enough large, ability unfreezing smoothly, if but jarring force is excessive, and the tensile strength that can exceed cable 5 causes cable 5 to be pulled off, and can realize unfreezing when usual jarring force is 31360 Ns (3.2 tons).
As the enforceable mode of one, the incoming frequency of frequency converter 3 is 0Hz ~ 50Hz, thus provides energy continually varying jarring force, and jarring force can not be excessive so that damage cable 5.
More preferably, jarring controlling organization 20 (namely controller 2) controls the jarring force value that bumper jar 6 produces and is less than the maximum tension force value of cable 5, and bumper jar 6 produces the jarring force that increases gradually until unfreezing, and unfreezing process steadily and can not damage cable 5.
Wireline logging release device of the present utility model, first by haulage gear 10 times payouts 5, by motor 1 swing roller 4, makes cable 5 discharge from cylinder 4, the logger 7 being connected to twister 6 lower end is sent into the shaft bottom of drilling well; Then reversely rotate cylinder 4 by motor 1, drum cable 5 on cylinder 4, thus on carry reclaim logger 7, obtain in the process that logger 7 is up and collect shaft bottom data.If logger 7 meets card in up process, controller 2 controls bumper jar 6 by frequency converter 3 and produces jarring force downwards, and the size of jarring force is adjusted by the change of frequency of frequency converter 3, until jarring force makes logger 7 in the unfreezing of stuck point position, continue after unfreezing to reclaim cable 5 until complete well logging.The utility model salvages logger 7 after avoiding breaking cable 5 again, and structure is simple and method of operating is simple, and dependable performance, saves manpower, improves efficiency.
