Abstract
The utility model provides a general sleeve grouting device. The device comprises a grouting device, a general cover plate, a fixing screw spike, a sleeve coupling, a sleeve and an union; a stepped inner hole is formed in the general cover plate; an inner hole that is matched with the sleeve coupling by the outside diameter, of the cover plate, is mounted in the sleeve coupling; the grouting pipe passes through the general cover plate to be inserted into the sleeve; a transverse screw hole is formed in the general cover plate; threads of the fixing screw spike are connected with the transverse screw hole; the sleeve coupling is ejected by the front end of the fixing screw spike; the union is connected to the upper end of the grouting pipe; an exhaust hole is formed in the upper end of the general cover plate. According to the general sleeve grouting device, the grouting pipe does not fall into the sleeve, the stepped inner hole is formed in the cover plate, thus the general cover plate can sleeve the sleeve coupling of different specifications, and as a result, a set of devices is applied to a plurality of kinds of sleeves; the grouting operation is convenient and safe, efficient drilling can be realized, and obvious economic benefit is brought.
Description
Technical field
The utility model is the wellhead equipment of oil field welldrilling, is sleeve grouting device, concrete a kind of universal sleeve grouting device.
Background technology
In oil drilling completion practice, before well cementing operation, need to be lowered in advance and in well, just can to carry out well cementing operation with the bunch tube of well cementation back-pressure valve.Because back-pressure valve is arranged at bunch tube bottom, be lowered in process at bunch tube, drilling fluid in well can not enter in bunch tube, the inside of bunch tube is empty, under buoyancy, bunch tube is descending very difficult, sometimes also because pipe string inside and outside differential pressure is large, cause the cementing tool such as back-pressure valve, packer, hanger, sizing collar that is connected to bunch tube bottom to damage, cause and cement the well unsuccessfully.Therefore, ensure that bunch tube is lowered to and puts in place smoothly, need constantly to cover ipe grout, with the pressure inside and outside balance set pipe string.Current grouting way is that rubber pipeline is inserted in bunch tube, and slush pump pours into mud in bunch tube by rubber pipeline.This mode is in the milk operate miss is easily occurred, and rubber pipeline is fallen in sleeve pipe, and also rubber pipeline throws away and hurts sb.'s feelings under pressure, produces heavy economic losses.
Summary of the invention
The purpose of this utility model is a kind of universal sleeve grouting device of design, makes its grouting operation convenience, safety, realizes efficient drilling well.
The purpose of this utility model is achieved in that and comprises grout pipe, general cover plate, setscrew, casing coupling, sleeve pipe, the oily ninth of the ten Heavenly Stems, casing coupling is connected with sleeve pipe, in general cover plate, be provided with step endoporus, the endoporus that the external diameter of general cover plate and casing coupling matches is arranged on casing coupling, grout pipe inserts in sleeve pipe through after general cover plate, on general cover plate, there is horizontal screw, the screw thread of setscrew is connected with described horizontal screw, the front end of setscrew withstands casing coupling, and the upper end of grout pipe connects the oily ninth of the ten Heavenly Stems.
The upper end of general cover plate is provided with steam vent.
The beneficial effects of the utility model are: grout pipe can not fall in sleeve pipe, in general cover plate, be provided with step endoporus, can be sleeved on the casing coupling of different size, one covering device adapts to multiple sleeve pipe, therefore, the utility model grouting operation is convenient, safety, can realize efficient drilling well, has significant economic benefit.
Brief description of the drawings
Fig. 1 is the utility model example structure figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, embodiment of the present utility model comprises grout pipe 1, general cover plate 3, setscrew 4, casing coupling 5, sleeve pipe 6, the oily ninth of the ten Heavenly Stems 7, casing coupling 5 is connected with sleeve pipe 6, in general cover plate 3, be provided with step endoporus, general cover plate 3 is arranged on casing coupling 5 with the endoporus that the external diameter of casing coupling 5 matches, and is provided with three grades of endoporus in accompanying drawing of the present utility model, and first order diameter of bore equals 5, and " " on casing coupling, second level diameter of bore equals 5 to the external diameter of casing coupling, can be sleeved on 5
1/
2" external diameter of box cupling can be sleeved on 5
1/
2" on casing coupling, third level diameter of bore equals the external diameter of 7 box cuplings, can be sleeved on 7 " on casing coupling, grout pipe 1 is through in the rear insertion sleeve pipe 6 of general cover plate 3, grout pipe 1 is welded on general cover plate 3, on general cover plate 3, there is horizontal screw, the screw thread of setscrew 4 is connected with described horizontal screw, can make the front end of setscrew 4 withstand casing coupling 5 by rotary fixing screw silk nail 4, thereby general cover plate 3 and grout pipe 1 are fixed on to well head, suppressing Shi Buhui is thrown out of, can not fall in sleeve pipe yet, the upper end of grout pipe 1 connects the oily ninth of the ten Heavenly Stems 7, can be connected grouting with the cementing truck of grouting.The macropore place of the junction of setscrew 4 and general cover plate 3 in general cover plate 3, can ensure that setscrew 4 withstands on the casing coupling of different size.The upper end of general cover plate 3 is provided with steam vent 2, and the gas in can drain sleeve 6, pours into cement paste smoothly.
Setscrew 4 has multiple being evenly distributed on general cover plate 3, can make general cover plate 3 stressed evenly, fixation.
