Abstract
The utility model relates to a high strength abutting tool in the construction technology of a wet joint type drilling and conveying well logging. The high strength abutting tool consists of a pump-down gun body, a female connector assembly, a female connector guard plate and a pressing plate, wherein the female connector assembly is arranged in the cavity of the pump-down gun body; drilling liquid leakage holes are arranged at the upper part of the pump-down gun body; the female connector guard plate is inversely locked outside the lower cavity of the pump-down gun body; the pressing plate is pressed on the tongue of the lower end of the female connector guard plate, and the pressing plate is fixed on the pump-down gun body via fixing screws. Compared with the prior art, the abutting tool inverts the female connector guard plate so that the female connector guard plate is integrally fixed on the pump-down gun body through the pressing plate and the screws so as to effectively avoid the dropping problems of the female connector guard plate during the abutting construction process; the drilling liquid leakage holes at the upper part of the pump-down gun body are changed into row type circular holes; the abutting tool changes the drilling liquid leakage structure so as to improve the integral strength of the abutting tool, solve the collision impact condition of the gun head position and provide reliable technical guarantee for the drilling and conveying well logging.
Description
Technical field
The utility model belongs to oil-gas exploration geophysical log technical field, relates to a kind ofly to bonding tool, and particularly a kind of wet joint formula that is used for is bored the high strength of defeated well logging construction technology to bonding tool.
Background technology
The key technology that the wet joint formula is bored in the defeated logging technique is to dock locking with bonding tool is finished in the down-hole with wet joint, and the quality of butt joint will directly influence the success rate of boring defeated logging operation.
At present known structure to bonding tool as shown in Figure 1, mainly form by gun main body under the pump 1, female assembly, female backplate 3 etc., the female assembly places under the pump in the gun main body 1, be provided with a female backplate 3 consistent under the pump outside the gun main body 1 with rifle material under the pump, female backplate 3 upper ends are provided with tongue, with the fixedly steel pin 6 of 1.8mm gun main body 1 under female backplate 3 and the pump are fixed together.When boring defeated logging operation, make the female assembly in the bonding tool, will insert the wet joint of transferring in the drilling tool hydrophthalmia to bonding tool and dock with in the down-hole with after logging cable is connected, logging cable with drilling tool transfer, on carry and finish brill and fail logging operation.The problem that above-mentioned known technology structure exists is: because the gun main body external diameter has only 51mm under the pump, main body wall thickness 3.5mm, influenced by circular arc and wall thickness, processing request is high, and install at the scene in the steel pin process, easily that gun main body hole support under female backplate and the pump is big, particularly carry out high speed when docking in the down-hole, be subjected to the effect of down-hole pressure and drilling fluid impulse force, being easy to occur steel pin is cut off, female backplate bottom outlet supportted bad and pump under gun main body steel wire pin-and-hole top supportted bad situation, cause the female backplate to support, female assembly off normal, can't finish butt joint, cause and bore defeated logging operation failure.In addition, be rectangle structure owing to be opened in the drilling fluid discharge orifice on gun main body top under the pump in the past, rifle head position intensity is reduced, bending deformation is hit in this position when causing butt joint, can not use repeatedly.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists on the fixing and drilling fluid discharge orifice structure at the female backplate, provide a kind of rational in infrastructure, easy to use and reliable, bulk strength is high, can effectively ensure bore defeated well logging smoothly the high strength of butt joint to bonding tool.
The technical scheme that adopts is so for achieving the above object: the high strength that is provided is made up of gun main body, female assembly, female backplate and pressing plate under the pump bonding tool, the female assembly places under the pump in the gun main body chamber, the top of gun main body has the drilling fluid discharge orifice under the pump, the female backplate is inverted outside the lower chamber of buckle closure gun main body under pump, pressing plate pressed put after on the tongue of female backplate lower end, pressing plate is fixed under the pump on the gun main body with fixed screw.
The realization of technical solutions of the utility model also is: have the circular drilling fluid discharge orifice of multiple row above the gun main body under pump, have a plurality of oval drilling fluid discharge orifices above the female backplate.
Compared with prior art, the utility model adopts female backplate upside down, use that pressing plate, screw are fixing to be fixed on its one under the pump on the gun main body, fall female backplate phenomenon when having avoided the construction butt joint effectively, simultaneously, change the drilling fluid discharge orifice above the gun main body under the pump into row's formula circular port, by changing drilling fluid earial drainage structure, improved bulk strength, solved the be impacted generation of distortion situation of rifle head position, successfully provide reliable guidance for boring defeated well logging to bonding tool.

Fig. 2 is the mounting structure schematic diagram of a specific embodiment of the utility model.
Fig. 3 is the floor map of female backplate.
Fig. 4 is the side direction view of female backplate.
Each label title is respectively among the figure: gun main body under the 1-pump, and 2-drilling fluid discharge orifice, 3-female backplate, the 4-pressing plate, the 5-fixed screw, 6-is steel pin fixedly.
The specific embodiment
Below with reference to accompanying drawing the utility model content is described further, but actual fabrication structure of the present utility model is not limited in illustrated embodiment.
Referring to accompanying drawing, high strength described in the utility model is made up of gun main body under the pump 1, female assembly, female backplate 3, pressing plate 4 and fixed screw 5 bonding tool.Gun main body is selected stainless steel material for use under the pump, and the female assembly is placed under the pump in gun main body 1 chamber.Female backplate 3 is selected the material consistent with gun main body 1 under the pump for use, and the thickness that is located at the tongue of female backplate 3 one ends is about 1/2 of female backplate 3 thickness.During installation female backplate 3 with tongue invert form buckle closure up under pump outside gun main body 1 lower chamber, pressing plate 4 is placed on the tongue of female backplate 3, by fixed screw 5 pressing plate 4 is fixed under the pump on the gun main body 1 together with female backplate 3, form integral structure, improved the bulk strength to bonding tool, the phenomenon of falling rifle head distortion under female backplate and the pump when having avoided butt joint takes place; In addition, have the circular drilling fluid discharge orifice of three row above the gun main body under pump, correspondence also has three oval drilling fluid discharge orifices 2 above the female backplate simultaneously.By above-mentioned to the female backplate contour structures and fixed form and pump under rifle head drilling fluid discharge orifice structure, improved bonding tool intensity, efficiently solve the problem that rifle head position is subject to collision deformation, for bore defeated well logging smoothly butt joint the robust techniques guarantee is provided.
