Description
Technical field
The utility model relates to a kind of abrasionproof equipment, particularly relates to the monolithic abrasionproof lining that step is located in a kind of protection.
Background technology
During drilling well; oil pipe four-way is arranged on well head, and in the process of making a trip, drilling rod tubing hanger of may damaging is located step; a kind of instrument abrasionproof of current employing lining; it is be arranged on the hollow sleeve on oil pipe four-way tubing hanger step surface, and surrounding is fixed by a circle jackscrew, is used for protecting tubing hanger to be located step; after putting in place under completion tubular column; first take out abrasionproof lining, then be seated in boll-weevil hanger, well head is installed.
But as depicted in figs. 1 and 2, it shows the abrasionproof lining for existing routine; the bottom of abrasionproof lining extends on the latus rectum of oil pipe four-way; due to the limited length of abrasionproof lining, the protection of boll-weevil hanger being located to step can only be realized, the protection of bottom pressure test plug being located to step cannot be realized.
Summary of the invention
The purpose of this utility model is to provide a kind of simultaneously protect boll-weevil hanger to be located monolithic abrasionproof lining that step and bottom pressure test plug are located step.
For achieving the above object, the concrete technical scheme of a kind of monolithic abrasionproof lining of the present utility model is:
A kind of monolithic abrasionproof lining; be set in oil pipe four-way; face is provided with first step and second step to abrasionproof liner outer wall; the tubing hanger of first step in oil pipe four-way is located step and is arranged; the pressure test plug of second step bottom oil pipe four-way is located step and arranges; drilling tool passes through in abrasionproof lining, and first step and second step are located step for the protection of tubing hanger and pressure test plug is located step, is located step and pressure test plug is located step and collides to prevent drilling tool and tubing hanger.
Further, abrasionproof lining is horizontally arranged with hole of confluxing, hole of confluxing is arranged near the side opening of oil pipe four-way, and hole of confluxing is mutually concordant with side opening, and fluid can enter oil pipe four-way from hole of confluxing by side opening.
Further, abrasionproof lining is provided with four holes of confluxing, hole of confluxing is symmetrical arranged.
Further, the bottom of abrasionproof lining extends to the top of the minimum latus rectum of oil pipe four-way.
Further, the top of abrasionproof lining is provided with crawl section, and instrument of fetching and delivering is connected with crawl section can fetch and deliver abrasionproof lining.
The advantage of a kind of monolithic abrasionproof lining of the present utility model is: when putting drilling tool and normally creeping into, can be located step protection to boll-weevil hanger, also can realize the protection of bottom pressure test plug being located to step.
Accompanying drawing explanation
Fig. 1 is the assembling drawing of existing abrasionproof lining and four oil pipes;
Fig. 2 is the structural representation of existing abrasionproof lining;
Fig. 3 is the assembling drawing of abrasionproof lining of the present utility model and four oil pipes;
Fig. 4 is the structural representation of abrasionproof lining of the present utility model.
Detailed description of the invention
In order to better understand the purpose of this utility model, structure and function, below in conjunction with accompanying drawing, further detailed description is done to a kind of monolithic abrasionproof lining of the present utility model.
As shown in Figure 3 and Figure 4, it shows for a kind of monolithic abrasionproof lining of the present utility model, be set in oil pipe four-way 2, abrasionproof lining 1 outside wall surface is provided with first step 31 and second step 41, the tubing hanger of first step 31 in oil pipe four-way 2 is located step 32 and is arranged, second step 41 is located step 42 near the pressure test plug of oil pipe four-way inner bottom part and arranges, drilling tool passes through in the hollow section of abrasionproof lining 1 inside, first step 31 and second step 41 are located step 32 for the protection of tubing hanger and pressure test plug is located step 42, be located step and pressure test plug to prevent drilling tool and tubing hanger to be located step and to collide, cause wearing and tearing.
Further, abrasionproof lining 1 is horizontally arranged with hole 5 of confluxing, hole 5 of confluxing is concordant with the side opening 21 in oil pipe four-way 2, and the fluid between sleeve pipe and drilling tool in annular space can be entered the flank of oil pipe four-way from hole 5 of confluxing by side opening 21, and hole 5 of confluxing can be used as the passage of annular fluid.Wherein, abrasionproof lining 1 is provided with four holes 5 of confluxing, hole 5 of confluxing is symmetrical arranged, and each hole of confluxing is arranged near four of oil pipe four-way 2 side openings 21 respectively.
Further, the bottom of abrasionproof lining 1 extends to the top of the minimum latus rectum of oil pipe four-way 2, to ensure that drilling tool passes through from the inside of abrasionproof lining, avoids drilling tool and to collide and the pressure test plug that weares and teares is located step 42.
Further, the top of abrasionproof lining 1 is provided with crawl section 6, and instrument of fetching and delivering is connected with crawl section 6 can fetch and deliver abrasionproof lining 1.
A kind of monolithic abrasionproof lining of the present utility model, when putting drilling tool and normally creeping into, can be located step protection to boll-weevil hanger, also can realize the protection of bottom pressure test plug being located to step.
By specific embodiment, the utility model is further described above; but it should be understood that; here concrete description; should not be construed as the restriction to essence of the present utility model and scope; one of ordinary skilled in the art to the various amendments that above-described embodiment is made, belongs to the scope that the utility model is protected after reading this specification.
