Background

In the domestic oil and gas drilling site, in order to prevent large-particle slurry drilling cuttings and other foreign matters from blocking a drill bit water hole in the drilling process, various drill rod filters need to be additionally arranged in a circulating system so as to achieve the purpose of filtering slurry, further reduce unnecessary tripping and improve the drilling speed.

The drill pipe filter core is installed on drill pipe box and kelly bar protection joint, and the present drill pipe filter core that uses is simple screen pipe form, but uses this kind of screen pipe form filter core, and solid-phase particle in the high pressure drilling fluid can hit on the filter core wall around the filtration pore after the filtration pore, perhaps on solid-phase particle directly hits the filter core wall, can produce the filter core and scrap safety problems such as fracture too early sometimes, has greatly shortened the life of filter core.

FIG. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic side view of the present invention;

fig. 3 is a schematic diagram of a filter screen nipple filter element structure.

Reference numbers in the figures: the top end is provided with an end face-1; a tip body-2; a filter screen boundary beam-3; a reinforcement ring-4; a bottom body-5; bottom flow hole-6; lifting lugs-7; and (4) a hole-8.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, 2 and 3, a filter cartridge with a short section of a filter screen is characterized by comprising a top main body 2, a bottom main body 5, a filter screen boundary beam 3 and a reinforcing ring 4. Preferably, the filter element synthetic material is stainless steel.

As shown in fig. 1: the top end main body 2 is a cylindrical structure with walls on the periphery and without an upper surface and a lower surface, a top end mounting end face 1 is fixedly arranged on the upper side of the top end main body, and the top end main body 2 and the top end mounting end face 1 are integrally formed. Preferably, two holes 8 are formed in the side wall of the top end main body 2, and the two holes 8 correspond to each other.

The bottom body 5 is a cylindrical structure with walls on the periphery, a lower surface but no upper surface, and a bottom flow hole 6 which is hemispherical and convex is fixedly arranged on the lower side of the bottom body. As shown in fig. 2: the bottom flow holes 6 are uniformly provided with flow holes 9;

as shown in fig. 1: the downside of top main part 2 with the upside shape of bottom main part 5 is identical, and is provided with a plurality ofly fixedly between the two filter screen boundary beam 3. Preferably, a plurality of the screen edge beams 3 have gaps therebetween. It is a plurality of filter screen boundary beam one end is fixed to be set up the downside of top main part 2, and the other end is fixed to be set up the upside of bottom main part 5, it is a plurality of 3 surfaces on the filter screen boundary beam are provided with beaded finish 4.

Example (b): the filter element is fixed at the middle position inside the drill rod through the top end mounting end surface 1 and the hole 8. The drilling fluid flows into the filter element through the top end main body 2, fine slurry in the drilling fluid passes through gaps between the filter screen boundary beams 3, and larger solid-phase particles in the drilling fluid can stay in the filter element due to the fact that the large solid-phase particles cannot pass through the gaps. The filter element reduces the area of the inner wall of the drill core, indirectly reduces the probability of collision between solid-phase particles in drilling fluid and the inner wall of the drill core, and avoids damage to the drill core.

The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the present invention is not limited to the specific combinations of the above-described technical features, and other technical features that are arbitrarily combined with each other or equivalent features may be included without departing from the scope of the present invention. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
