Abstract
The invention discloses a kelly protective joint inner step type filtering screen device of a top drive system. The device comprises a lengthened Kelly protective joint (1) and a filtering screen (2), an axial through hole (3) is formed in the lengthened Kelly protective joint (1), the upper end and the lower end of the lengthened Kelly protective joint (1) are provided with a female buckle end (4) and a male buckle end (5) respectively, a step (6) is arranged in the through hole (3) of the lengthened Kelly protective joint (1), the upper end of the filtering screen (2) is fixedly provided with a filtering screen frame (7), the filtering screen (2) is disposed in the through hole (3), and the filtering screen frame (7) and the step (6) form stopping fit. The filtering screen is arranged in the lengthened Kelly protective joint, placement of the filtering screen is irrelevant to a drill pipe, and accordingly filtering of drilling fluid can be achieved through a drill pipe without an inner step. The kelly protective joint inner step type filtering screen device is simple in structure, convenient to machine, low in investment cost, remarkable in economic benefit, good in application prospect and capable of being widely used in the field of marine and land oil-gas field engineering.
Description
Technical field
The invention belongs to offshore oilfield field of engineering technology, is that one is suitable for without step drilling rod Novel filtering net device.
Background technology
At present, marine drilling of the prior art has been used the instrument such as directional well, well logging during in a large number, and these instruments require to place filter screen in drilling tool, filters solid phase and foreign material in drilling fluid, ensures that downhole instrument normally moves.
Conventional filter screen is to be placed on the interior step of drilling rod, and the complete post of every brill, need to take out the filter screen of a upper post, is placed in next post.This filter screen requires every cylindrical drill bar all to possess interior step.But at present a large amount of what use is the drilling rod without interior step, as 5-1/2 ", 5-7/8 " drilling rod.Because this class drilling rod cannot be placed filter screen, can not effectively filter solid phase in drilling fluid, can not ensure that downhole tool normally moves.
Above-mentioned discussion content object be to reader introduce may to below by the various aspects of the technology relevant various aspects of the present invention that are described and/or advocate, believe that this discussion content contributes to provide background information for reader, to be conducive to understanding better various aspects of the present invention, therefore, should be appreciated that it is to read these with this angle to discuss, instead of admit prior art.
Summary of the invention
The object of the invention is to avoid deficiency of the prior art and provide a kind of TDS side to protect step filter net device in joint, to adapt to a large amount of drilling rods without interior step that use at present, solve without interior step drilling rod drilling fluid filtration problem.
Object of the present invention is achieved through the following technical solutions:
Provide a kind of TDS side to protect step filter net device in joint, comprise and add rectangular guarantor's joint and filter screen, described adding in rectangular guarantor's joint, is provided with axial through hole, the top and bottom that add rectangular guarantor's joint are respectively arranged with box end and pin end, add rectangular guarantor's joint and in through hole, be provided with step, the upper end of described filter screen is fixedly installed screen holder, and described filter screen is arranged in through hole, and described screen holder forms backstop with step and coordinates.
Wherein, described step is ring-shaped step, and described screen holder is toroidal frame, and screen holder diameter is greater than the internal diameter of step.
Wherein, described through hole is divided into the different epimere of diameter and hypomere from top to bottom, and the diameter of epimere is greater than the diameter of hypomere, and the junction of epimere and hypomere forms described step.
Wherein, the upper end of described filter screen and screen holder connect and fix.
The present invention places filter screen in joint is protected by side, and filter screen is placed with drilling rod and had nothing to do like this, realizes without interior step drilling rod drilling fluid and filtering.The present invention is simple in structure, easy to process, cost of investment is low, remarkable in economical benefits, and application prospect is good, can extensive use in ocean and land oil gas field engineering field.
Brief description of the drawings
The invention will be further described to utilize accompanying drawing, but embodiment in accompanying drawing does not form any limitation of the invention, for those of ordinary skill in the art, is not paying under the prerequisite of creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is the structural representation that step filter net device in joint is protected by TDS side.
Detailed description of the invention
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, it should be noted that, in the situation that not conflicting, the feature in the application's embodiment and embodiment can combine mutually.
Core of the present invention is to provide a kind of TDS side to protect step filter net device in joint, and it can adapt to a large amount of drilling rods without interior step that use at present, solves without interior step drilling rod drilling fluid filtration problem.
As shown in Figure 1, step filter net device in joint is protected by TDS side of the present invention, comprises and adds rectangular guarantor's joint 1 and filter screen 2.Described adding in rectangular guarantor's joint 1, is provided with axial through hole 3, and the top and bottom that add rectangular guarantor's joint 1 are respectively arranged with box end 4 and pin end 5.Box end 4 is respectively used to be connected top with pin end 5 and drives and drilling rod.Describedly add rectangular guarantor's joint 1 and in through hole 3, be provided with step 6, the upper end of described filter screen 2 is fixedly installed screen holder 7, and the upper end of described filter screen 2 and screen holder 7 connect and fix.Described filter screen 2 is arranged in through hole 3, and described screen holder 7 forms backstop with step 6 and coordinates.Described step 6 is ring-shaped step, and described through hole 3 is divided into the different epimere of diameter and hypomere from top to bottom, and the diameter of epimere is greater than the diameter of hypomere, and the junction of epimere and hypomere forms described step 6.Described screen holder 7 is toroidal frame, and screen holder 7 diameters are greater than the internal diameter of step 6, and screen holder 7 can be sat and be hung on step like this, forms backstop and coordinates.
