Abstract
The utility model relates to a safe environment-friendly slurry pouring device for drilling well, which comprises a circulating joint body, a slurry pouring pipeline, a slurry return outlet, a slurrydiversion hose and a shockproof pressure gauge, wherein the shockproof pressure gauge and the slurry return outlet are arranged at the upper end of the circulating joint body, the slurry diversion hose is connected with the upper end of the slurry return outlet through a union, a slurry pouring port is horizontally arranged on the side surface of the circulating joint body, and the slurry pouringport penetrates through the circulating joint body and is connected with the vertically arranged slurry pouting pipeline. The utility model has the advantages that the operation and the use are convenient, the full-automatic slurry pouring is realized, the redundant slurry can be automatically recycled, and the well mouth and the blowout preventer body are hygienic and clean; and the situations that the slurry overflows from the slurry pouring pipeline to dirty the well mouth and the drilling platform and to cause inconvenience to the operation of running casings because of slight careless inthe past are avoided. The device is suitable for slurry pouring devices for drilling all kinds of wells.
Description
Technical field
The utility model design is a kind of drilling tool, specifically in the wellbore construction process, during casing job, need pour into a kind of safe mud grouting device of drilling fluid in sleeve pipe.
Background technology
Under the prior art condition, the method for mud grouting is in the casing job: utilize slush pump, the mud in the circulating tank is transmitted by mud line, directly pump in the sleeve pipe.Fill-up line is that fill-up line is directly put into sleeve pipe with being connected of sleeve pipe, and fixing means is with rope bundle jail.Its shortcoming is, if fixing insecure or mud grouting pressure is bigger than normal, have the mud of pressure pipeline can be suppressed and holds, cause mud to spray, equipment on the rig floor of making dirty and instrument also can be hurted sb.'s feelings sometimes, both uneconomical, environmental protection do not have safety guarantee again, are unfavorable for the carrying out of casing job.
Summary of the invention
The purpose of this utility model provide a kind of can economy, environmental protection, in sleeve pipe, pour into the device of mud safely; Helping casing job carries out smoothly.
Mud grouting device of the present utility model, its structure is returned outlet, mud stream guiding tube, shockproof pressure meter by circulating connection main body, fill-up line, mud and is formed, shockproof pressure meter and mud return the upper end that outlet is arranged on the circulating connection main body, the upper end that mud returns outlet is connected with the mud stream guiding tube by union, circulating connection main body side has been horizontally disposed with the mud grouting mouth, and the mud grouting mouth passes the circulating connection main body and is connected with vertically disposed fill-up line.
This mud grouting device great advantage of the present utility model is: easy for operation, realized full-automatic mud grouting, and changed when passing by mud grouting, need the workman in the well head manual operation, not only time-consuming but also require great effort.Unnecessary mud be can also reclaim automatically, well head, blowout preventer main body health, cleaning made; Having changed the past causes mud to overflow in fill-up line through regular meeting, and make dirty well head and rig floor face cause construction inconvenience.This device is compared with prior art, and having when the mud grouting operation can economy, environmental protection ground construction operation, and safe, flexible and convenient operation improves construction quality, accelerating construction progress, reduces industrial accident, is suitable for other setting of casing mud grouting operation of various wells.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of drilling well with safety and environmental protection mud grouting device.
Description of reference numerals
Circulating connection main body 1, fill-up line 2, mud grouting inlet 3, mud return outlet 4, mud stream guiding tube 5, shockproof pressure meter 6, screw thread 7.
The specific embodiment
With reference to Figure of description device of the present utility model is done following detailed explanation.
As shown in drawings, safety and environmental protection mud grouting device of the present utility model, its structure by circulating connection main body 1, fill-up line 2, mud return outlet 4, mud stream guiding tube 5, shockproof pressure meter 6 are formed, shockproof pressure meter 6 and mud return the upper end that outlet 4 is arranged on circulating connection main body 1, the upper end that mud returns outlet 4 is connected with mud stream guiding tube 5 by union, circulating connection main body 1 side has been horizontally disposed with mud grouting mouth 3, and mud grouting mouth 3 passes circulating connection main body 1 and is connected with vertically disposed fill-up line 2.
The lower ending opening of circulating connection main body 1, the bottom cylindrical is processed with screw thread 7.
Embodiment
When this mud grouting device was used, the lower end screw thread was connected with the well head sleeve pipe, and connected mode is to be threaded; The mud grouting mouth of side is connected with hose, and connected mode is that union connects; The flow-guiding mouth of upper end is connected with the mud stream guiding tube, and connected mode is that union connects.Its operating principle is that the mud that pours into is entered by the mud grouting inlet, through fill-up line, enter in the bunch tube from the pipeline end opening, flow out by the mud flow-guiding mouth of mud grouting device upper end, turn back in the bore hole annulus through the water conservancy diversion pipeline because of entering gas that mud gets rid of or unnecessary mud.
This mud grouting device great advantage is easy for operation, has realized full-automatic mud grouting, has changed when passing by mud grouting, needs the workman in the well head manual operation, and is not only time-consuming but also require great effort.Unnecessary mud be can also reclaim automatically, well head, blowout preventer main body health, cleaning made; Having changed the past causes mud to overflow in fill-up line through regular meeting, and make dirty well head and rig floor face cause construction inconvenience.This device is compared with prior art, and having when the mud grouting operation can economy, environmental protection ground construction operation, and safe, flexible and convenient operation improves construction quality, accelerating construction progress, reduces industrial accident, is suitable for other setting of casing mud grouting operation of various wells.
In wellbore construction, be used for setting of casing midway, in sleeve pipe mud grouting, with balancing sleeve string inside and outside differential pressure, guarantee that sleeve pipe normally goes into the well smoothly.
