Abstract
A side passing automatic mud flow fill bushing float collar belongs to one mechanical device of the petroleum industry field, which is an automatic mud flow fill bushing installation in the shaft drilling construction and the well cementing operation of petroleum development and geological exploration. The improvement is a side passing automatic mud flow fill bushing float collar, in which the circular channels are made inside the body and between the large ball holder and the body. The body inside is provided with the large ball holder, a sealing ball as well as a Toland closing sleeve. A small ball holder, a movable base, pins and baffles are installed above the body. The main advantage of the utility model is that the mud flow can be automatically filled in the casing process. At the same time the bonding and locking between the bushing and the well wall which usually occur during the casing process can be eliminated. Thus, the operation accidents are reduced and the casing speed is enhanced. Moreover the labour intensity and production cost are reduced as well.
Description
One, technical field: the utility model belongs to a kind of mechanical device in petroleum industry field, is the casing bit of mud grouting automatically in wellbore construction such as oil field development and geological prospecting and the well cementing operation.
Two, technical background: do not have the float collar of automatic mud grouting device on the used market of past, when setting of casing, because of the outer mud of sleeve pipe because the effect of float collar can not be returned in the sleeve pipe, cause that mud is excessive, sleeve pipe is emptied too much, transfers resistance and increases, it is excessive easily to produce the sleeve pipe external resistance, sleeve pipe produces distortion, and intensity is influenced, for this reason, every 1～2 mark mud down, needing had both influenced setting of casing speed toward the interior mud grouting of sleeve pipe, increased labour intensity and cost again.
Three, summary of the invention: the utility model makes and realizes automatic mud grouting in the production for addressing the aforementioned drawbacks, and improves to make to be the automatic mud grouting casing float collar of side general formula.Mainly in body, make annular flow path between big ball seat and body; Mud by lower bottom base upper-side hole, Toland and little ball seat, enters upper sleeve, to reach automatic mud grouting again by lower bottom base lower-side hole and annular flow path in the setting of casing process.This casing float collar mainly is to be equipped with big ball seat, ball sealer and Toland to close cover in body, and little ball seat and movable pedestal and pin, baffle plate etc. are installed above body.
Use the main effect of this covering device to be: automatic mud grouting in the setting of casing process, can eliminate the sticking card between recurrent sleeve pipe and the borehole wall in the setting of casing process simultaneously, reduce work accident; Replace artificial mud grouting operating type, improve setting of casing speed, reduce labour intensity and cost of production.
Four, description of drawings:
As figure is the automatic mud grouting casing float collar of side general formula structural representation
Explain: 1, body 2, spring 3, ball sealer 4, pin 5, joint hoop 6, baffle plate 7, lining 8, movable pedestal 9, bead seat 10, Toland close cover 11, big ball seat 12, lower bottom base
Five, accompanying drawing implementation:
Assembled body 1 in joint hoop 5, in body 1 above mounting bush 7 and movable pedestal 8 and bead seat 9, be fastened on lining 7 one sides by pin 4 baffle plate 6 be housed.Below body 1, be shaped on lower bottom base 12 and big ball seat 11, make annular flow path between lower bottom base 12, big ball seat 11 and the body 1; Ball sealer 3 and spring 2 are installed in the body 1; Between movable pedestal 8 and big ball seat 11, the Toland is installed and closes cover 10.In the work operations, instantly behind the intact sleeve pipe, normal turn on pump circulation is when preparing well cementation, one Metal Ball is dropped in the sleeve pipe, when treating that ball arrives bead seat 9, the pressure of spraining is cut off pin 4 outer surface of shear, it is descending that movable pedestal 8 is closed cover 10 together with the Toland, by-pass prot is closed in the pass, pins from dog chart, stops automatic mud grouting.The pressure of spraining is again cut off surface of shear in the pin, and bead seat 9 goes downwards to Toland 10, and device is connected the back pressure valve of tubing string bottom, the operation of beginning conventional cementing.
