Cov khoom siv sib xyaw siv hauv Composite Choj ntsaws thiab Frac Plug

Lub ntsiab lus ntawm cov khoom sib xyaw yog ib yam uas yog tsim los ntawm ntau tshaj ib yam khoom. Rau peb lub hom phiaj, composite yog hais txog fiberglass. Tag nrho cov ntsaws ruaj ruaj yog feem ntau ua los ntawm cov khoom siv fiberglass, uas yog kev sib xyaw ntawm cov iav fibers thiab cov khoom siv cob. Cov iav fibers yog nyias nyias, 2-10 npaug me dua tib neeg cov plaub hau, thiab yog tas li thiab mob / woven rau hauv cov resin los yog tws thiab molded rau hauv cov resin. Cov khoom siv cob yog dab tsi khi cov iav ua ke, ua kom nws zoo li qub. Hauv paus, iav fibers thiab resin yog ua ke ces kho rau hauv ib qho khoom. Nyob rau hauv tas li ntawd, cov khoom yog machined rau hauv cov duab uas yuav siv tau. Muaj ntau txoj hauv kev los ua ke cov resin thiab iav kom ua tiav lub hom phiaj xav tau. Qee cov txheej txheem kev tsim khoom siv sib xyaw siv hauv kev tsim cov khoom sib txuas yog cov kab mob filament, convolute qhwv, thiab resin hloov cov khoom sib xyaw. Txhua hom no muab cov cob thiab iav hauv txoj hauv kev kom ua tiav cov khoom sib txawv.

Filament Qhov txhab

Nrog filament qhov txhab sib xyaw, cov iav txuas txuas txuas ntxiv yog rub los ntawm cov kua nplaum los pleev xim rau lawv. Tom qab ntawd cov fibers raug mob nyob ib ncig ntawm lub mandrel hlau los tsim ib lub raj ntawm cov khoom sib xyaw. Thaum qhov xav tau sab nraud txoj kab uas hla (OD) ntawm kev sib xyaw ua tiav, cov raj sib xyaw & hlau mandrel raug tshem tawm ntawm lub tshuab winding thiab kho hauv qhov cub kom tsim tau cov khoom sib xyaw. Tom qab kho, cov hlau mandrel raug tshem tawm thiab cov raj txuas ntxiv tuaj yeem ua rau cov khoom sib txawv.

Filament wound composite yog qhov zoo heev rau cov khoom siv tubular. Lawv tuaj yeem tsim kho nrog cov iav tshwj xeeb, hom resin, thiab cov qauv cua ntawm cov iav fibers. Cov kev hloov pauv no tuaj yeem hloov kho kom ua tiav cov hom phiaj sib txawv nrog rau kev sib tsoo ntau dua, siab dua tensile, siab dua qhov ntsuas kub, yooj yim milling, thiab lwm yam. Tag nrho cov no muaj txiaj ntsig rau kev tsim cov khoom sib xyaw frac plugs vim peb ua haujlwm hauv ib lub raj thiab yuav tsum tau teeb tsa hauv ib lub raj. (casing).

Tsis tas li ntawd, cov tshuab filament winding tuaj yeem cua mus txog 30 'cov raj ntawm cov khoom sib xyaw, qee qhov tuaj yeem cua 6 ntawm cov raj no ib zaug. Nws yog ib qho yooj yim los tsim cov ntim ntawm filament qhov txhab sib xyaw nrog cov nqi qis ntawm kev ua haujlwm. Qhov no qiv nws tus kheej los tsim cov khoom ntim ntawm tus nqi qis.

Convolute

Thaum lub tshuab filament siv cov iav txuas ntev ntev los qhwv cov iav iav rau hauv cov raj, convolute composite yog tsim los ntawm cov iav ntaub uas twb impregnated nrog resin. Cov ntaub ntawv "pre-preg" no yog mob nyob ib ncig ntawm lub mandrel los tsim ib lub raj, thiab tom qab ntawd kho kom khov rau hauv cov khoom sib xyaw. Qhov txiaj ntsig ntawm kev siv cov ntaub ua los ntawm iav, es tsis yog cov hlua txuas ntxiv, yog tias koj tau txais lub zog ntawm iav hauv ob qho kev qhia. Qhov no ntxiv zog ntxiv rau cov khoom sib xyaw rau tensile thiab compressive daim ntaub ntawv.

Resin Hloov

Nrog hloov molding lub iav ntaub yog stacked los yog tsim nyob rau hauv ib tug pwm rau hauv ib tug tshwj xeeb zoo. Tom qab ntawd cov ntaub yog impregnated nrog cov resin los ntawm kev hloov cov txheej txheem. Cov resin tuav ntawm qhov kub thiab txias hauv ib lub nkoj thiab cov iav ntaub yog tuav hauv lub tshuab nqus tsev. Cov resin yog ces tso rau hauv lub tshuab nqus tsev ib puag ncig ntawm iav, yuam cov resin rau hauv lub voids ntawm cov iav fibers nyob rau hauv cov ntaub. Cov kev sib xyaw yog tom qab ntawd kho thiab machined los tsim qhov kawg.

Moulded Composite

Moulded composites siv Bulk Molding Compounds (BMC) los tsim cov duab sib xyaw siv los txhaj lossis compression molding. BMC yog iav ntaub los yog tws fibers uas yog tov nrog ib tug resin. Cov tebchaw no yog muab tso los yog txhaj rau hauv pwm thiab tom qab ntawd thermoset lossis kho nyob rau hauv qhov kub thiab txias. Cov txiaj ntsig ntawm molded composite yog muaj peev xwm ua kom sai sai tsim cov duab nyuaj hauv ntim.

Muaj ntau txoj hauv kev sib txuas cov resin nrog cov iav thiab cov no tsuas yog ob peb txoj hauv kev siv hauv kev tsim cov khoom sib xyaw frac plugs. Dab tsi yog qhov tseem ceeb yog qhov sib xyaw yog yooj yim millable rau hauv me me. Tsis tas li ntawd, kev sib xyaw ua ke ntawm iav thiab resin ua rau lub ntiajteb txawj nqus ntawm 1.8-1.9 tsim cov khoom uas yooj yim nqa los ntawm lub qhov dej thaum lub sijhawm milling.

Npuag Khoom

Thaum teeb tsa cov ntsaws ruaj ruaj, cov cuab yeej tau muab tso rau hauv qhov dej nrog cov "slips". Nyob rau hauv qhov tseeb, muaj ib tug cone ua ke nrog ib tug wedge. Lub npoo yuav muaj cov tawv tawv tawv uas thaum yuam kom lub khob hliav qab yuav "tom" rau hauv lub casing, tsim kom muaj lub thauj tog rau nkoj uas muaj peev xwm kaw lub ntsaws rau hauv qhov chaw thiab tiv thaiv cov rog ntau tshaj 200,000 lbs. Rau lub plam mus rau "tom" rau hauv lub casing lub hardened cheeb tsam los yog cov khoom yuav tsum nyuaj tshaj lub casing nws tus kheej, uas yog feem ntau ~ 30 HRC.

Composite lub cev Slips nrog Inserts

Qhov thib ob feem ntau siv configuration ntawm ib daim tiab hauv qab yog lub cev sib xyaw nrog cov nyees khawm tawv los muab cov khoom thauj.

Hlau Khawm

Qee cov plugs muaj cov nyees khawm ua los ntawm cov hlau, txawm tias tag nrho cov cam khwb cia hlau los yog hmoov hlau. Hmoov hlau nyees khawm yog tsim los ntawm sintering metallic hmoov rau hauv cov duab xav tau los ntawm lub pob. Thaum cov hmoov hlau zoo li nws yuav yooj yim dua rau zom / zeb nws tag nrho yog nyob ntawm cov hmoov hlau, kev kho cua sov, thiab kev tsim khoom.

Ceramic Khawm

Qee cov plugs sib xyaw siv cov khoom sib xyaw nrog cov nyees khawm ceramic los muab qhov tom rau hauv lub casing. Txawm hais tias cov khoom siv ceramic yog tawv heev, nws kuj yog nkig heev. Qhov no tso cai rau cov nyees khawm ceramic kom tawg tau zoo dua thaum lub sijhawm milling thaum piv rau lub pob hlau. Ceramic muaj SG ntawm 5-6, ua rau lawv yooj yim me ntsis tshem tawm thaum lub sij hawm milling uas lawv cov hlau counterparts.

Slip Millability

Kev tsom xam ntau yog muab tso rau ntawm lub sij hawm milling rau ib qho kev sib txuas uas lub hom phiaj ntawm milling lub plugs qee zaum yuav tsis nco qab. Lub hom phiaj kawg ntawm kev ua haujlwm milling yog tshem tawm cov plugs ntawm lub qhov dej. Yog, nws yog ib qho tseem ceeb kom ua tiav sai thiab rau cov khoom me me. Txawm li cas los xij yog tias koj rhuav tshem lub ntsaws sai sai thiab txawm tias tau txiav me me, tab sis koj tsis tshem cov khib nyiab los ntawm lub qhov dej lub hom phiaj tseem tsis tau tiav. Xaiv lub ntsaws nrog cov hlau nplaum lossis cov nyees khawm yuav ua rau nws nyuaj rau tshem tawm tag nrho cov khib nyiab los ntawm cov plugs vim yog qhov tshwj xeeb ntawm cov khoom siv.

Vigor's Composite Bridge Plug thiab Frac Plug yog tsim los ntawm cov khoom siv sib xyaw ua ke, nrog rau kev xaiv rau ob qho tib si cam khwb cia hlau thiab cov khoom sib xyaw tsim raws li cov neeg siv khoom tshwj xeeb. Peb cov khoom tau ua tiav nyob rau hauv cov roj av thoob plaws Tuam Tshoj thiab thoob ntiaj teb, tau txais cov lus pom zoo los ntawm cov neeg siv khoom. Kev cog lus rau kev ua tau zoo thiab kev tsim kho, peb xyuas kom meej tias peb cov kev daws teeb meem ua tau raws li qhov tshwj xeeb xav tau ntawm txhua qhov project.
