Abstract
The utility model discloses a pump lower gun, which comprises a lower gun, a lower gun protection cylinder, a cable pressing strip, a female connector assembly and a female connector assembly cover plate. Step grooves are arranged at the two ends of the female connector assembly cover plate. The female connector assembly cover plate is clamped at a position of the lower gun corresponding to the female connector assembly through the step grooves. The pump lower gun has the advantages that the structure is simple, the design is reasonable, the pump lower gun is convenient to install and the cable pressing strip is firmly fixed; and since the lower gun is an integral structure, the situation that a cable core is disconnected with female connector assembly pin connecting wire can be effectively avoided and logging construction is guaranteed to be smoothly conducted.
Description
Technical field
The utility model relates to the horizontal wellbore logging technical field, particularly relates to rifle under a kind of pump.
Background technology
Rifle is finished the success rate that the quality of docking locking can directly affect logging operation with snap joint under the pump in the down-hole in the construction of wet joint formula horizontal wellbore logging.Rifle mainly is comprised of helmet, hold down gag, lower rifle protection cylinder, cable press strip, torpedo, lower rifle, female assembly, female assembly cover plate etc. under the pump that uses at present; the female assembly places in the lower rifle, and the position of the outer corresponding female assembly of lower rifle is by fixation with steel wire female assembly cover plate.Rifle carries out high speed when docking with snap joint under this pump in inserting well logging, because impact is large and the momentum effect of drilling fluid, be easy to occur that steel wire is cut off, female assembly cover plate bottom outlet is supportted bad situation, cause female assembly cover plate to support, rifle assembly off normal can't be finished docking under the pump, thereby causes the logging operation failure.
The utility model content
The purpose of this utility model is exactly the problem for above-mentioned prior art, and rifle under a kind of simple in structure, easy for installation, pump that the construction that can effectively guarantee to log well is carried out smoothly is provided, and solves the problems of the technologies described above fully.
The purpose of this utility model realizes by following technical proposals:
Rifle under a kind of pump comprises lower rifle, lower rifle protection cylinder, cable press strip, female assembly, female assembly cover plate, and step trough is offered at described female assembly cover plate two ends, is connected to the position of the outer corresponding female assembly of lower rifle by step trough female assembly cover plate.
Further, described lower rifle protection cylinder is one-body molded with the cable press strip.
Traditional cable press strip has the nut of the lower rifle protection of compression cylinder, and nut easily dropped when rifle was transferred operation under pump, and having cancelled nut behind the employing said structure can thoroughly address this problem.
Further, the external diameter of described lower rifle protection cylinder is 46mm.
Adopt this external diameter so that under the pump rifle entire outer diameter be 46mm, can be smoothly drilling tool by 51mm.Solved that rifle easily occurs having some setbacks by drilling tool under the pump of present external diameter 48mm, 51mm, even the problem of blocking.
Further, described lower rifle is the integral type structure.
This structure can effectively be avoided cable conductor and come off with female assembly contact pin line.
The beneficial effects of the utility model are: simple in structure, reasonable in design, easy for installation, the cable press strip is fixing firm; A lower rifle protection cylinder chucking female assembly cover plate can avoid under the pump rifle to transfer that female assembly cover plate drops in the running; Lower rifle is the integral type structure, can effectively avoid cable conductor and female assembly contact pin line to come off, thereby the construction that guarantees to log well is carried out smoothly.

The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Extremely shown in Figure 5 such as Fig. 1; rifle under a kind of pump; comprise lower rifle 2, lower rifle protection cylinder 1, cable press strip 5, female assembly 4, female assembly cover plate 3; step trough 31 is offered at described female assembly cover plate 3 two ends; the step trough 31 of female assembly cover plate 3 left ends is connected between lower rifle protection cylinder 1 and the lower rifle 2, and the step trough 31 of right-hand member is pressed on lower rifle 2 inwalls.
As shown in Figure 5, described lower rifle protection cylinder 1 is one-body molded with cable press strip 5.
The external diameter of described lower rifle protection cylinder 1 is 46mm.
Described lower rifle 2 is the integral type structure.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
