Abstract
The utility model relates to an auxiliary tool for a casing for petroleum drilling and completion, in particular to a circulating pressurization disc, which comprises a body, wherein a female buckle is machined on the upper end of the body, a pressurization disc is designed on the body, the lower end of the body is sleeved with a sealing ring, the position of the body, positioned at the lower end of the sealing ring, is sleeved with a space bush, and the bottom end of the body is connected with a guide shoe. According to the utility model, the friction during the installation of the casing is reduced, the difficulty of the installation of the casing is reduced, the safety is improved, and the defect that the existing completion casing has large friction and difficulty during the installation is overcome.
Description
Technical field:
The utility model relates to a kind of oil drilling completion setting of casing aid, particularly a kind of circulation pressurization disk.
Background technology:
At present, in the oil drilling field, the enforcement of exceptional well types such as directional well, horizontal well, extended reach well and shallow seated groundwater horizontal well is more and more; And in the completion setting of casing process of these exceptional well types; Because drilling well well segment length, the completion tubular column rigidity is big and the shaft bottom desilting is more, causes the resistance of setting of casing mill to increase; And the drill string self gravitation is difficult to overcome and bores down the mill resistance, causes completion casing to be lowered to that difficulty increases even can't be down to design finishing drilling well depth.
The utility model content:
The technical problem that the utility model will solve provides a kind of circulation pressurization disk, and this device has been realized the resistance of reduction setting of casing mill, reduces the setting of casing difficulty, improves safety.Overcome existing completion casing and be lowered to the mill resistance greatly, the deficiency that difficulty is big.
The technical scheme that the utility model is taked is: a kind of circulation pressurization disk comprises body; The body upper end is processed with box, is designed with pressurization disk on the body, and the body lower end is set with sealing ring, on the body of sealing ring lower end, is set with spacer, and the body bottom is connected with guide shoe.
The beneficial effect of the utility model is: the utility model is owing to adopted the mode of design pressurization disk on body; Thereby can't descend fashionable at sleeve pipe; Can pressurization disk be acted on the casing coupling through transferring the utility model, drive pressurization through the top; Realize sleeve pipe continue be lowered to, reduce the setting of casing difficulty; Owing to adopted mode at body lower end suit sealing ring; Thereby guarantee the sealing between circulation time the utility model and the sleeve pipe, make drilling fluid in confined space, set up circulation, and then the desilting in shaft bottom is suspended; With drilling fluid upwards migration leave the shaft bottom; Reduce the resistance of setting of casing mill, guaranteed that well is unobstructed, improve the safety that sleeve pipe is lowered to.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing, a kind of circulation pressurization disk comprises body 1; Body 1 upper end is processed with box, is designed with pressurization disk 2 on the body 1, and body 1 lower end is set with sealing ring 3, on the body 1 of sealing ring 3 lower ends, is set with spacer 4, and body 1 bottom is connected with guide shoe 5.
The main body one of the utility model processes, and intensity is high, and body 1 upper end is processed with box, and is furnished with the protection joint, can drive with the top to be connected, and realizes being communicated with.Can realize in the work progress being in the milk at any time, during the situation that in the setting of casing process, occurs being lowered to, can the utility model be put into sleeve pipe through transferring action, through pressurization disk 2 contact casing couplings, pressurization downwards realizes that casing string continues to be lowered to; Under the more situation of down-hole desilting, can realize the sealing between the utility model and sleeve pipe by the sealing function of sealing ring 3; Carry out the turn on pump circulation; The shaft bottom desilting is left the shaft bottom with the drilling fluid migration, and then reduce because the frictional resistance that desilting causes helps being lowered to smoothly of sleeve pipe.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
