Description
Technical field
The utility model relates to a kind of manufacturing technology field of sleeve grouting circulant solution card device, particularly a kind of manufacturing technology field of valve assembly of sleeve grouting circulant solution card device.
Background technology
When boring the completion setting of casing, in order to guarantee the casing string internal and external pressure balance, drilling technology requires every following 1～2 sleeve pipe all will fill drilling fluid in tubing string, originally drilling fluid charge is to draw the sebific duct operation by driller, and is very inconvenient, and labour intensity is very big, and often leak filling, influence the setting of casing quality.In addition, when setting of casing is hampered, also need whole taking-up of sleeve pipe changed the rod bit drifting, again one one of sleeve pipe is connected G.I.H again, very trouble has also had a strong impact on the drilling well timeliness.
In order to address this problem, abroad some big drilling tool companies have developed setting of casing grouting circulant solution card device as Halliburton Company, Wei Defu company.This instrument was equipped with as must being equipped with of drilling contractor abroad, and China just began imitated this product, small lot batch manufacture at present in 1997.Sleeve pipe drilling fluid charge release device is made up of tool joint, glue envelope assembly, valve assembly, guiding tube assembly 4 parts, and valve assembly is partly tied enough complexity, and is difficult in maintenance.
The utility model content
Big in order to solve artificial drilling fluid charge labour intensity, with the valve assembly complex structure in the existing sleeve pipe drilling fluid charge release device, problem such as difficult in maintenance, it is a kind of simple in structure that the utility model provides, the valve assembly of new casing grouting circulant solution card device easy to use.
The utility model comprises the valve urceolus, one way valve, in described valve urceolus, valve body is set, in described valve body, spool is set, in the upper surface of spool one pipe plug is set, in the upper surface of described pipe plug one pad is set, described pad and pipe plug are by being bolted to the upper surface of spool, upper end at described valve body is provided with one way valve, rubber hose coupling is threaded in the lower end of described valve urceolus, the latter half of described spool is arranged in the rubber hose coupling, at the interior end of described rubber hose coupling step surface is set, and the outer wall at described spool middle part is provided with a radial projection, at spring of described spool overcoat, the two ends of described spring are separately positioned on radial projection and the step surface.
During use, the tool joint of installing is connected with power swivel central tube lower external thread joint; During normal casing job, the guiding tube of device bottom has been inserted in the endoporus of single sleeve pipe, single sleeve pipe is with after tubing string connects, get final product the turn on pump drilling fluid charge, drilling fluid is filled the back termination of pumping, again power swivel and release device are carried on together, the opening device valve can be sealed device with the drilling fluid in the upper center tube post, can not pollute rig floor, if be hampered in the process middle and lower part of trapping, no matter in any position, all the glue envelope assembly of release device can be lowered in the sleeve pipe tubing string, make glue envelope seal lip enter sleeve pipe top endoporus, the turn on pump circulating fluid, glue is enclosed under the drilling liquid pressure effect, seal aperture, sleeve pipe top, make the pressure drilling fluid act on the position that is hampered, bottom, circulate, to reach the purpose of separating the resistance unfreezing, the utility model is with valve body, spool, rubber hose coupling is set to one whole, be in order to make this device easy to loading and unloading, be arranged to one and also help leakproof, sleeve grouting circulant solution card device is simple in structure, easy to use, can solve the automatic drilling fluid charge of sleeve pipe effectively and be hampered and separate the problem of resistance, improve the drilling well timeliness greatly, guaranteed cased quality.
One way valve described in the utility model is made up of steel ball, spring, pressure cap, seal washer, in the upper end of described valve body one through hole is set, the interior end at described through hole is provided with step surface, described pressure cap is threaded in the through hole, between described pressure cap and step surface, steel ball is set, spring and seal washer is set respectively at the two ends up and down of described steel ball.
This one way valve is set is for complete when stuck in the sleeve pipe bottom, also can't de-plugging by drilling liquid pressure, this moment can termination of pumping, discharge the drilling liquid pressure in central tube and the standpipe, the one way valve of valve assembly discharges in the device simultaneously, the drilling liquid pressure in the casing string is discharged thereupon, the pressure cap of one way valve is arranged on the top, both made things convenient for installation, can reduce machining accuracy again, cut down finished cost.
In order to improve spring-supported stability, between described radial projection and spring, spring pad is set.
