Abstract
An environmental-friendly buffer type guide pipe for mousehole used in the petroleum drilling machine comprises a mousehole pipe (1) for collecting the drilling mud carried by the drill rod and buffering of the impact force of the drill rod, and a guide apparatus (2) positioned in the moushole pipe (1). The top of the guide apparatus (2) is equipped with a cover plate supporting the drill rod head, the guide apparatus (2) is covered by a buffer flexible element (3) and the lower end is inserted into a guide nozzle (4), and the upper part of the guide nozzle (4) is connected to the bottom of the mousehole pipe (1). Due to addition of the flexible buffer element, the utility model greatly reduces the impact force of the drill rod, meanwhile, the mud can flows into the connector via the guide nozzle, thereby avoiding the environmental pollution.
Description
Technical field:
The utility model belongs to the oil-well rig manufacturing field of equipment, its major function is used for oil-well rig and the drilling rod of preparing to come into operation is risen to the rig floor face in advance and inserts in it at drilling process, so that field worker operation and effective a kind of equipment of save operation time, a kind of specifically have can collect drilling mud fluid and can play the rat hole conduit that the buffering drilling rod is transferred impact force.
Background technology:
At present, oil-well rig adopts a hollow cylinder steel pipe directly to be inserted into the method for foundation from the rig floor face with the rat hole conduit usually, and this device has the following disadvantages: the one, and drilling rod subsidiary mud in drilling well has pollution, can't collect; The 2nd, drilling rod has impact force to damage the drilling rod screw thread easily when being lowered to rat hole, influences drilling life of drill pipe.
Summary of the invention
The utility model purpose is a kind of environment-friendly type buffer-type rat hole conduit of design.
Specifically, a kind of oil-well rig is with environment-friendly type buffer-type rat hole conduit, and it has collects the drilling mud fluid that drilling rod carries and can cushion the guider (2) that drilling rod is transferred the rat-hole scabbard of impact force (1) and is positioned at rat-hole scabbard (1); The cover plate that bears the drilling rod head is arranged at guider (2) top, is with buffering flexible member (3) and lower end on the guider (2) and stretches in the guiding adapter (4), and guiding adapter (4) top is connected with rat-hole scabbard (1) bottom and circumferential location is provided with a plurality of apertures.
The rat hole conduit has two kinds of schemes: a kind of is whole no clamp connection type; Another kind is segmented and uses clip (7) to connect.
Described guider (2) centre is designed to hollow, and design has a plurality of arcs of recesses gap or circular hole on the top blind flange periphery.
The rat-hole scabbard epimere (6) of strip slip-collar interconnection system rat hole conduit and rat-hole scabbard hypomere (8) connect as one with clip (7), sealing ring (9) and collar clamped bolt (10).
Buffering flexible member (3) is that spring or other band elastomeric material are made.
Owing to be provided with elastic buffer component, weaken the impact force of drilling rod greatly in the utility model, protected the screw thread of drilling rod, prolonged drilling life of drill pipe; Mud can be taken over by guiding and flow into joint simultaneously, has avoided environment pollution.
Description of drawings:
Accompanying drawing 1 does not have clamping hoop type rat-hole scabbard structural representation for the utility model.
Accompanying drawing 2 is the utility model strip slip-collar formula rat-hole scabbard structural representation.
The explanation of accompanying drawing 1 sequence number:
1, rat-hole scabbard; 2, guider; 3, buffer spring; 4, guiding is taken over;
5, joint accompanying drawing 2 sequence numbers explanation:
6, rat-hole scabbard epimere; 7, clip; 8, rat-hole scabbard hypomere; 9, sealing ring;
10, clamping bolt.
The specific embodiment
A kind of have can collect drilling mud fluid and can play the buffering drilling rod rat hole conduit of transferring impact force.As shown in Figure 1: this rat hole conduit is by rat-hole scabbard (1), guider (2), buffer spring (3); Guiding is taken over (4); Joint component such as (5) are formed.The cover plate that bears the drilling rod head is arranged at guider (2) top, is with buffering flexible member (3) and lower end on the guider (2) and stretches in the guiding adapter (4), and guiding adapter (4) top is connected with rat-hole scabbard (1) bottom and circumferential location is provided with a plurality of apertures.
What Fig. 2 explained is a kind of rat hole conduit of strip slip-collar, compared to Figure 1, removing rat-hole scabbard (1) is divided into two, change rat-hole scabbard epimere (6), rat-hole scabbard hypomere (8) into by one section, and increased outside clip (7), sealing ring (9) and the collar clamped bolt (10), all the other internal constructions and form and Fig. 1 are identical, and it is the installation and maintenance etc. of being convenient to inner orientation device (2), buffer spring component such as (3) that this structure adopts the advantage of clamp connection.
Accompanying drawing 2 schemes are compared with accompanying drawing 1 scheme, rat-hole scabbard in the accompanying drawing 1 (1) is a monolithic, rat-hole scabbard in the accompanying drawing 2 (6,8) is split type, and have clip (7), sealing ring (9) and collar clamped bolt (10) etc., all the other internal constructions and form and Fig. 1 scheme are identical, and the advantage of this structure is that guider (2), the buffer spring component installation and maintenance such as (3) of rat-hole scabbard inside are more convenient.
The course of work of this utility model is: when drilling rod is sling insertion rat-hole scabbard (1), the drilling rod head at first contacts with guider (2) upper surface cover plate, guider (2) compresses buffer spring (3) after being subjected to drilling rod to transfer impact force and gravity, thereby makes drilling rod can steadily insert rat-hole scabbard; In addition, drilling rod is in inserting rat-hole scabbard (1) process, in order to guarantee that the entrained at work drilling mud fluid of drilling rod can reclaim, unlikelyly cause environment pollution, be designed to hollow in the middle of the guider (2), and design has four (also can be two, three or more) arcs of recesses gap (also can be circular hole etc.) on the top blind flange periphery, and guiding is taken over (4) top circumferential location that is connected and is provided with a plurality of apertures etc. bottom rat-hole scabbard (1), all can make mud liquid flow to joint (5) smoothly and locate.During actual the use, on-the-spotly only need to go up to connect flexible pipe etc. and be introduced into mud to collect in the box promptly recyclable at joint (5).
