Abstract
The utility model relates to a vehicle-loaded well-cementing and batch-mixing pipe of a petroleum and natural gas well-cementing device. Four identical electrical controlled proportioning valves mutually connected to form an electrical control ring structure are added to an input pipe formed by a slurry-mixing pot, a conduit and a batch-mixing pot. And, four identical pneumatic controlled butterfly valves mutually connected to form a pneumatic controlled ring structure are added to an output pipe formed by a batch-mixing pot, a conduit and a slurry-filling pump. Continuous slurry mixing and batch mixing can be realized through the pipe device disclosed in the utility model. A filling centrifugal pump and a circulating centrifugal pump are replaceable with each other. Moreover, the pipe device meets the well-cementing requirements on cement slurry and is suitable for vehicle-loaded well-cementing and batch-mixing pipe arrangement.
Description
Technical field
The utility model relates to oil, natural gas facility, particularly relates to well cementing operation equipment.
Background technology
Well cementation batch mixing equipment be for cement the well continuously, the equipment of the high quality water that is mixed out in enormous quantities mud.Present well cementation batch mixing equipment all is skid and drags assembling structure, can be bigger for the space of its line arrangement, and piping installation is more open, and the car installing is equipped with country strict dimensional requirement is arranged, skid and drag the dress well cementation batch mixing equipment can't be in car dress layout.
The circular centrifugal pump line road of the pipeline setting of existing well cementation batch mixing equipment and perfusion centrifugal pump pipeline are two independent each other and disconnected pipelines, during well cementing operation, if wherein the centrifugal pump on pipeline breaks down, cement paste can not be mixed smoothly and cause well cementing operation to stop, even make whole well cementing operation failure.
Summary of the invention
The purpose of this utility model is to provide a kind of well cementation batch mixing device of car dress, and it is improved original well cementation batch mixing equipment, is suitable for the equipment of car dress.
The technical solution of the utility model is:
The utility model is made up of a high-pressure injection centrifugal pump, ejector, slurry mixing tank, two batch-handling mixers, a perfusion centrifugal pump and circular centrifugal pump, a conduit, its high-pressure injection centrifugal pump, conduit, ejector, slurry mixing tank are formed cement and are mixed the slurry pipeline, slurry mixing tank, conduit, circular centrifugal pump are formed circulation line, slurry mixing tank, conduit, a batch-handling mixer are formed intake line, and another batch-handling mixer, conduit, perfusion centrifugal pump are formed output pipe; Set up 4 identical electronically controlled proportional valves that are interconnected into automatically controlled circular ring structure on the described intake line, set up 4 identical gas control butterfly valves that are interconnected into the gas control circular ring structure on the output pipe.
The utility model has the advantages that:
1, the utility model can be realized continuously mixed slurry, mixed slurry also can be regulated the cement slurry volume of batch-handling mixer in batches.
2, automatically controlled circular ring structure of the present utility model and gas control circular ring structure can solve the problem of the exchange function of jar notes centrifugal pump and circular centrifugal pump, when promptly wherein a centrifugal pump breaks down, another centrifugal pump can substitute and use and guarantee that well cementing operation normally carries out, and makes two centrifugal pumps have the function of mixing slurry, plasma discharge.
3, dwindle the line arrangement space, be suitable for the car dress and arrange.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing embodiment, the utility model is described in further detail.
Among Fig. 1: high-pressure injection centrifugal pump 28, conduit, ejector 16, slurry mixing tank 9 are formed the cement slurry mixed pipe line; Slurry mixing tank 9, conduit, circular centrifugal pump 19 are formed the circular centrifugal pipeline, and slurry mixing tank 9, conduit, 4,17,4 identical electronically controlled proportional valves 24,25,26,27 that are interconnected into automatically controlled circular ring structure of batch-handling mixer constitute intake line; Slurry mixing tank 9, conduit, 4,17,4 identical gas control butterfly valves 20,21,22,23 that are interconnected into electric control circular ring structure of batch-handling mixer constitute output pipe.When mixing slurry continuously, clear water offers ejector 16 after being pressurizeed by high-pressure injection centrifugal pump 28 through Hand-operated butterfly valve 1 or 2, carry out just mixing at ejector 16 with cement by the compressed air input, circular centrifugal pump 19 sucks cement paste through gas control butterfly valve 7 from slurry mixing tank 9, reach gas control butterfly valve 12 by the road, 11 enter ejector 16 secondary mixing slurry, or more thus the bar pipeline repeatedly circulate and mix slurry, cement paste is by 3 " the non-radioactive densometer is to slurry mixing tank 9; after its density meets well cementation and requires; by perfusion centrifugal pump 5 cement paste via gas control butterfly valve 8; 6, manual butterfly valve 14 or the 15 supplies pump suction sides of cementing the well.
During toward batch-handling mixer 4,17 slip castings, its perfusion centrifugal pump 5 sucks cement paste from slurry mixing tank 9, cement paste is by gas control butterfly valve 8, perfusion centrifugal pump 5, electronically controlled proportional valve 26, gas control butterfly valve 3 injects cement paste to batch-handling mixer 4, also can inject cement paste to batch-handling mixer 17 by gas control butterfly valve 8, perfusion centrifugal pump 5, electronically controlled proportional valve 25, gas control butterfly valve 18.Batch-handling mixer 4 or 17 output cement pastes: promptly when well cementation pump input cement paste, cement paste is through gas control butterfly valve 20, perfusion centrifugal pump 5 sucking-off cement paste from batch-handling mixer 4 in the annulus.Export to well cementation pump suction side through gas control butterfly valve 6, manual butterfly valve 14 or 15; Also can be by sucking-off cement paste in the batch-handling mixer 17 after in the annulus gas control butterfly valve 22, perfusion centrifugal pump 5, gas control butterfly valve 6, manual butterfly valve 14 or 15 flow to well cementation pump suction side.
Circular centrifugal pump 19 is from batch-handling mixer 4 sucking-off cement pastes, gas control butterfly valve 21 and gas control butterfly valve 13, Hand-operated butterfly valve 14 or 15 flow to well cementation pump suction side in annulus, perhaps circular centrifugal pump 19 is from batch-handling mixer 17 sucking-off cement pastes, and gas control butterfly valve 23, gas control butterfly valve 13, manual butterfly valve 14 or 15 flow to well cementation pump suction side in annulus.
