Hauv kev ua haujlwm hydraulic fracturing, "plaub-nti plunger" feem ntau txhais tau hais tias 4-nti (kwv yees li 10.16 cm) txoj kab uas hla hauv lub twj tso kua mis frac. Raws li ib qho ntawm cov khoom tseem ceeb ntawm hydraulic ib feem ntawm lub twj tso kua mis high-pressure plunger, nws yog ib feem ntawm lub siab-siab foob thiab xa system nrog rau lub tog raj kheej liner, gland seal thiab li qub. Nws txoj haujlwm thiab daim ntawv thov muaj feem cuam tshuam nrog cov kev cai yooj yim ntawm kev ua haujlwm hydraulic fracturing.
Muaj nuj nqi ntawm Plaub Nti Hydraulic Fracturing Plunger
Muab cov kua dej siab siab: Lub plunger reciprocates nyob rau hauv lub tog raj kheej liner, converting mechanical zog los ntawm tus tsav kawg rau hauv hydraulic zog los ntawm kev hloov lub ntim ntawm lub foob chamber. Vim nws qhov loj hla ntu ntu, plaub-nti plunger tuaj yeem tso cov kua dej ntau ntawm qhov siab (feem ntau dhau ntawm 100 MPa), ua qhov tseem ceeb ntawm lub zog kom ua tiav qhov tawg.
Muab kev ruaj khov pulsating txaus: Cov theoretical ntws ntawm lub twj tso kua mis plunger nyob ntawm lub plunger txoj kab uas hla, stroke ntev thiab reciprocating zaus, tsis hais lub siab tawm. Qhov no ua kom muaj qhov nruab nrab ntws tsis tu ncua. Txawm hais tias instantaneous flow exhibits pulsations, kev siv ntau lub tog raj kheej configurations (xws li peb-lub tog raj kheej systems) zoo smoothes tus khiav, xyuas kom meej continuation thiab stability ntawm fracturing ua hauj lwm.
Kho kom haum rau qhov hnyav hnyav thiab qhov chaw corrosive siab: Fracturing fluids muaj cov khoom tseem ceeb, xws li silica xuab zeb, uas ua rau muaj kev cuam tshuam loj ntawm cov khoom siv sab hauv. Plaub-nti plungers feem ntau yog tsim los ntawm lub zog siab, cov khoom siv siab hnav (xws li ceramic-coated steel) los tiv thaiv kev kub ceev reciprocating motions thiab abrasive ib puag ncig, muab cov cuab yeej siv lub neej ntev thiab kev ntseeg siab.
Daim ntawv thov ntawm 4-nti plungers rau hydraulic fracturing
Raws li cov khoom siv tseem ceeb hauv cov tsheb thauj khoom frac (lossis frac cov tsheb thauj khoom), 4-nti plungers ua haujlwm hauv qab no lub hom phiaj tseem ceeb:
Hydraulic Fracturing Operations: Ua haujlwm raws li cov khoom tseem ceeb ntawm hydraulic fracturing twj tso kua mis, lawv ncaj qha mus rau lub twj tso kua mis high-pressure, high-volume hydraulic fracturing kua (muaj xws li dej, proppant thiab tshuaj additives) rau hauv av reservoirs. Cov txheej txheem no ruptures pob zeb, tsim cov kab nrib pleb, yog li ua kom cov hydrocarbon ntau lawm.
Haum rau ntau yam kev siv roj av: Cov pistons loj no tau siv dav hauv hydraulic fracturing ua haujlwm hauv cov roj av loj, suav nrog Daqing, Changqing, Shengli thiab shale gas teb. Lawv yog ib qho tseem ceeb tivthaiv rau kev ua tau zoo ntawm unconventional hydrocarbons xws li shale gas thiab nruj roj..Plunger
Ua hauj lwm hauv kev sib koom ua ke nrog cov khoom siv ntxiv: Plaub-nti plunger yuav tsum muaj kev sib koom ua ke nrog lub tog raj kheej kheej kheej, ntim khoom (cov khoom sib khi) thiab lwm yam khoom. Lub caj pas foob kaw qhov sib txawv ntawm lub plunger thiab lub tog raj kheej liner, tiv thaiv kom tsis txhob muaj kuab paug siab kom ntseeg tau tias lub twj tso kua mis ua haujlwm thiab kev nyab xeeb ntawm kev ua haujlwm. Peb txais tos koj cov lus nug txog kev muab khoom.
