Abstract
The utility model relates to a petroleum tool, in particular to a well-testing blowout-prevention pipe capable of laying a well-testing tool after being folded. The well-testing blowout-prevention pipe comprises a pipe body consisting of an upper pipe body (1) and a lower pipe body (2), wherein an upper hinge arm (3) and a lower hinge arm (4) are respectively arranged on the outer walls of the upper pipe body (1) and the lower pipe body (2); the upper pipe body (1) is hinged with the lower pipe body (2) through the upper hinge arm (3) and the lower hinge arm (4); and the lower mouth of the upper pipe body (1) is connected with the upper mouth of the lower pipe body (2) through a sealing part and a locking device (5). The foldable well-testing blowout-prevention pipe has the advantages of safety and convenience in use, and can greatly reduce the labor intensity and improve the construction safety.
Description
Technical field
The utility model relates to petroleum tool, is specifically related to the well testing lubricator that the well testing instrument is thrown in a kind of collapsible back.
Background technology
In the test job in oil field, some index is to require to finish just so-called airtight well logging under working environment.There is very high pressure in well head when airtight well logging, and the process of removing of tester must just can be finished by lubricator.The widely used lubricator in each oil field all is whole vertical type lubricator for a long time, must first overall fixed partly coiling on the connector in this lubricator work progress the well head production tree, because the well testing test does not have the hanging device of other drives, so can only be by manually finishing, waste time and energy very much, and the lubricator top that must climb to three meters high removes instrument, operation wants both hands to take instrumentation, catch on the balance that lubricator keeps health with one leg, whole weight is all born by other one leg, careless slightly will disequilibrium, throw from above, cause casualty accident thus.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of collapsible well testing lubricator is provided.
Technical solution of the present utility model is: it comprises body, described body is made up of upper tube body and lower tube body, upper tube body and lower tube body outer wall are respectively equipped with articulated jib and following articulated jib, upper tube body and lower tube body are hinged by last articulated jib and following articulated jib, and the lower nozzle of upper tube body is connected with locking device by seal with the upper orifice of lower tube body.
Technique effect of the present utility model is: it has advantage safe and convenient to use, has alleviated working strength of workers greatly, has improved working security.
Description of drawings
Fig. 1 cuts open structural representation for office of the present utility model.
The specific embodiment
As shown in Figure 1, it comprises body, described body is made up of upper tube body 1 and lower tube body 2, upper tube body 1 and lower tube body 2 outer walls are respectively equipped with articulated jib 3 and following articulated jib 4, upper tube body 1 and lower tube body 2 are hinged by last articulated jib 3 and following articulated jib 4, and the upper orifice of the lower nozzle of upper tube body 1 and lower tube body 2 is connected with locking device 5 by seal.
The upper orifice of the lower nozzle of described upper tube body 1 and lower tube body 2 is that cone match is connected.
Described locking device 5 comprises the card platform 7 and the screw thread that cooperate with locking nut 6 that the junction of locking nut 6 and upper tube body 1 and lower tube body 2 is respectively equipped with.
But the tube wall of described upper tube body 1 is provided with the emptying valve 8 of releasing tube cavity pressure.
The tube wall of described upper tube body 1 is provided with stop, can be used for locating logging tool, stop is made up of shell 9 and gag lever post 10, shell 9 is vertically fixed on the wall of upper tube body 1, gag lever post 10 is connected in the shell 9 by screw thread and seal and gag lever post 10 1 ends can be screwed in the tube chamber of upper tube body 1, and gag lever post 10 other ends are provided with the portion that screws 11 that is used for the application of force.
This lubricator is made up of two parts, at first to be fixed on base on the production tree in the construction, and then the top of lubricator connected by hinge removably hang on the base, successively tester is contained in the lubricator, installs pulley assembly 12, blowout prevention box 13, and then be that fulcrum erects top with the hinge, be seated in the tapered hole of the base mouth of pipe, realize sealing by sealing ring, screw locking nut 6 and finish installation work, whole process all is to finish on ground, alleviate working strength of workers greatly, improved working security.
