Abstract
The utility model discloses an easily-drilling hybrid blind plate applicable for the oil drilling well completion field, comprising an upper part joint, a body, a glass structure, a cement structure, a glass structure and a lower part joint, wherein the components of the cement structure are added with a swelling agent and fiber; and the connection between the glass structure and the body is fixed through the upper part joint and the lower part joint. The easily-drilling hybrid blind plate has the advantages that: the maximum external diameter is the same as that of a casing collar, the normal descending of a pipe string is not influenced; the drilling is easy, no burr is left after drilling and the late working is not influenced; the structure is firm and the bearing capability is strong; and the adoption of the glass and cement mixing structure effectively prevents the fracture and has high reliability.
Description
Technical field
The utility model is that a kind of easy brill formula in oil drilling completion field that is applicable to is mixed blind plate.
Background technology
Blind plate is a kind of instrument commonly used in the completion practice, and the blind plate that uses mainly is the aluminum blind plate at present.In use there is following defective in the aluminum blind plate: at first, aluminum blind plate material is softer, in boring the mill process, if control improper, very easily form aluminium flake, the parcel drill bit, might cause the danger of bit freezing: in addition, after the aluminum blind plate bores and removes, because the characteristic of material itself, always can remaining burr, like this can to the later stage down in the pipe operation bring hidden danger, might cause the operation failure.
Summary of the invention
Blind plate is gone up at the scene as instrument commonly used in a kind of completion practice and is used more and more widely, and the easy brill of blind plate etc. also are the key factors that influences the horizontal well completion quality.The aluminum blind plate of using on the scene exists easy boring property poor, has bored defectives such as remaining burr.The purpose of this utility model be to provide have that drillability is good, bearing capacity is strong, be easy to bore remove, a kind of easy brill formula in oil drilling completion field that is applicable to of reliability advantages of higher mixes blind plate.
The utility model is achieved in that a kind of easy brill formula that is applicable to oil drilling completion field mixes blind plate and mainly be made up of top sub, body, cement structures, glass structure and bottom joint.Add expansion agent and fiber in the cement structures composition, body all adopts and is threaded with top sub, bottom joint, and there is sawtooth projection at the body middle part, and all there is screw thread top and the bottom, and glass structure was fixed with being connected by top sub and bottom joint of body.Adopt between body and the cement structures and be stained with sand and be connected.
The utlity model has following advantage:
(1) maximum outside diameter is identical with casing coupling, does not influence the pipe string and normally is lowered to;
(2) easily bore, do not stay burr behind the brill, do not influence the later stage operation;
(3) sound construction, bearing capacity is strong;
(4) adopt glass and cement mixing structure, effectively prevent to break the reliability height.
Description of drawings
Fig. 1 is that easy brill formula is mixed the blind plate schematic diagram.
1 top sub, 2 bodies, 3 glass structures, 4 cement structures, 5 glass structures, 6 bottom joints
The specific embodiment
Now the utility model will be further described in conjunction with Figure of description.
As shown in the figure, at body 2 upper and lower sides screw thread is arranged all, sawtooth projection is arranged on the inner headed face, be stained with sand between body 2 and the cement structures 4 and handle, glass structure 3,5 was fixed with being connected by top sub 1 and bottom joint 6 of body 2.
In the completion practice, this easily the brill formula mix blind plate with the completion tubular string be lowered to put in place after, carry out cementing job.Then, drilling rod is mixed and is sent drill bit to be lowered into the blind plate position, bores glass structure 3,5 and cement structures 4, makes up and down to be communicated with, and carries out subsequent job.
Claims (2)
1. an easy brill formula that is applicable to oil drilling completion field is mixed blind plate, constitute by top sub (1), body (2), glass structure (3), cement structures (4), glass structure (5), bottom joint (6), it is characterized in that: add expansion agent and fiber in cement structures (4) composition, body (2) all adopts with top sub (1), bottom joint (6) and is threaded, there is sawtooth projection at body (2) middle part, all there is screw thread top and the bottom, and glass structure (3), (5) were fixed with being connected by top sub (1) and bottom joint (6) of body (2).
2. a kind of easy brill formula in oil drilling completion field that is applicable to as claimed in claim 1 is mixed blind plate, it is characterized in that: employing is stained with sand and is connected between body (2) and the cement structures (4).
