Abstract
The utility model relates to a circulating head for a cementing well. The circulating head is characterized in that the circulating head comprises a circulating head body and a connector with a pipe union concave head which are produced into a whole. The circulating head has the advantages that the connector with the pipe union concave head and the circulating head body are processed into a whole, the structure is simple, the service life is long, the processing cost is saved, labors are safer during the construction particularly, and the construction quality is higher.
Description
Technical field
The utility model relates in recover petroleum and the natural gas process, and when needing circulating mud when well cementing operation, the circulating mud instrument of use particularly relates to a kind of well cementation hydraulic circulating head.
Background technology
In recover petroleum and natural gas process, well cementing operation is a very important ring, and the quality of well cementing operation directly has influence on the quality of oil well.Circulating mud is the snap joint by cementing head the earliest, come circulating mud with cementing head, though this method also can reach the purpose of circulating mud, owing to will employ cementing head than large equipment, therefore, expense height and lay day are long, working strength of workers is big.Occur a kind of instrument that is named as hydraulic circulating head afterwards, during use hydraulic circulating head had been connected in the snap joint of cementing head, be connected to circulating mud on the sleeve pipe of oil well by snap joint.Come circulating mud compared with providing cost savings greatly with hydraulic circulating head, alleviated working strength of workers with the cementing head circulating mud.But, yet carrying out machine to joint that has the recessed head of union and hydraulic circulating head body respectively, present hydraulic circulating head couples together by taper thread, this hydraulic circulating head exists problem such as safety weak point in relatively poor, application life when trouble, construction of processing.
Summary of the invention
The utility model provides a kind of construction safety, processing, easy-to-install well cementation hydraulic circulating head for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of well cementation hydraulic circulating head, comprise hydraulic circulating head body and the joint that has the recessed head of union, and described hydraulic circulating head body manufactures one with the joint that has the recessed head of union.
Advantage and the good effect that the utlity model has are: the joint and the hydraulic circulating head body that have the recessed head of union are processed into one, and simple in structure, long service life has been saved processing cost; Prior when construction personnel safer, construction quality is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-1, hydraulic circulating head body; 1-2, joint.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of well cementation hydraulic circulating head, the joint 1-2 and the hydraulic circulating head body 1-1 that have the recessed head of union are processed into one, keep in its work progress the hydraulic circulating head body that has block teeth formula structure that links to each other with snap joint in the cementing head, with the joint that has the recessed head of union that is connected with pipeline, yet it partly links by taper and connects being processed as two originally, improves as a whole.Hydraulic circulating head body and the joint that has the recessed head of union are manufactured one.
Usually hydraulic circulating head mainly contains two parts composition: joint and hydraulic circulating head body two parts of having the recessed head of union are formed.
The joint that has the recessed head of union above the hydraulic circulating head that uses is connected with the hydraulic circulating head body by taper thread at present, hydraulic circulating head will bear the high pressure of several 10MPa and not allow seepage in work progress, tapered thread is undoubtedly part the weakest on the hydraulic circulating head, therefore require not only requirement of strength height of tapered thread, and sealing to be got well.If in construction, not only constructor's safety is constituted a threat in case leakage takes place, and directly influence cementing quality, may cause scrapping of whole well when serious, no matter therefore from personal security, or cementing quality does not allow hydraulic circulating head to go wrong in work progress.May go wrong in the hydraulic circulating head work progress for fear of tapered thread, the utility model provides that a kind of structure is simple, safety is better, longer New Cycle head of life-span.This hydraulic circulating head has been cancelled the joint that has the recessed head of union and the tapered thread between the hydraulic circulating head body and both are made of one them.This hydraulic circulating head is simple in structure, not only significantly reduced processing cost, what is more important has been avoided owing to screw thread is often dismantled the life-span that influences hydraulic circulating head, and is safer to personnel in the work progress, construction quality is more guaranteed, has also prolonged the application life of hydraulic circulating head simultaneously.
Claims (1)
1. a well cementation hydraulic circulating head comprises hydraulic circulating head body and the joint that has the recessed head of union, it is characterized in that: described hydraulic circulating head body manufactures one with the joint that has the recessed head of union.
