Cov qauv thiab kev faib tawm ntawm Packer

Lub koom haum International rau Standardization (ISO) thiab American Petroleum Institute (API) tau tsim tus qauv [saib ISO 14310: 2001(E) thiab API Specification 11D1 npaj los tsim cov lus qhia rau cov tuam txhab thiab cov neeg siv kawg hauv kev xaiv, tsim khoom, tsim. , thiab kev soj ntsuam kuaj ntawm ntau hom packers muaj nyob rau hauv lub khw niaj hnub no. Tej zaum qhov tseem ceeb tshaj, cov qauv kuj tsim kom muaj qhov tsawg kawg nkaus ntawm cov kev txwv uas cov chaw tsim khoom yuav tsum ua raws li kev thov kom haum. Lub International Standard yog tsim nrog cov kev cai rau ob qho tib si kev tswj kom zoo thiab tsim kev txheeb xyuas nyob rau hauv rankings. Muaj peb qib, lossis qib, tsim los rau kev tswj kom zoo thiab rau qib (ntxiv rau ib qib tshwj xeeb) rau kev tsim qauv.

Cov qauv kev ua tau zoo nyob ntawm qib Q3 txog Q1, nrog qib Q3 nqa yam tsawg kawg nkaus uas yuav tsum tau muaj thiab Q1 qhia txog qib siab tshaj plaws ntawm kev tshuaj xyuas thiab kev tsim cov txheej txheem pov thawj. Cov kev cai tseem raug tsim los tso cai rau cov neeg siv kawg hloov kho cov phiaj xwm zoo kom tau raws li nws daim ntawv thov tshwj xeeb los ntawm kev suav nrog cov kev xav tau ntxiv raws li "kev xav tau ntxiv."

Rau cov qauv tsim-validation qib ntawm V6 txog V1. V6 yog qib qis tshaj, thiab V1 sawv cev rau qib siab tshaj plaws ntawm kev xeem. Ib qib tshwj xeeb V0 tau suav nrog kom ua tau raws li cov txheej txheem lees paub tshwj xeeb. Cov hauv qab no yog cov ntsiab lus luv luv piav qhia txog cov kev cai yooj yim ntawm ntau theem ntawm cov qauv kev lees paub.

Qib V6 tus neeg muag khoom / chaw tsim khoom txhais

Qhov no yog qib qis tshaj tsim. Qib kev ua tau zoo hauv qhov piv txwv no yog txhais los ntawm cov chaw tsim khoom rau cov khoom lag luam uas tsis ua raws li cov qauv ntsuas pom hauv qib V0 txog V5.

Qib V5 ua kua

Nyob rau hauv qib no, lub packer yuav tsum tau teem nyob rau hauv lub siab tshaj plaws puab txoj kab uas hla (ID) casing nws yog rated rau ntawm qhov siab tshaj plaws kev khiav hauj lwm kub. Cov kev ntsuas ntsuas yuav tsum tau teem nrog qhov tsawg kawg nkaus packoff quab yuam los yog siab raws li teev los ntawm cov chaw tsim tshuaj paus. Kev ntsuas siab yog ua nrog dej lossis roj hydraulic rau qhov siab tshaj qhov sib txawv-siab ntsuas ntawm lub ntim khoom. Yuav tsum muaj ob lub siab thim rov qab thoob plaws lub cuab yeej, txhais tau tias nws yuav tsum tau ua pov thawj tias lub pob yuav tuav lub siab ntawm ob sab saum toj thiab hauv qab. Lub sijhawm tuav rau txhua qhov kev xeem yuav tsum muaj tsawg kawg yog 15 feeb ntev. Thaum kawg ntawm qhov kev xeem, cov packers rov qab tau yuav tsum tuaj yeem raug tshem tawm ntawm qhov kev sim ntsuas los ntawm kev siv cov txheej txheem ntawm nws qhov kev npaj tsim.

Qib V4 kua ntsuas + axial loads

Hauv qib no, tag nrho cov tsis muaj nyob hauv Qib V5 siv tau. Ntxiv nrog rau kev dhau V5 cov qauv, nws kuj yuav tsum tau ua pov thawj tias cov pob khoom yuav tuav qhov sib txawv ntawm kev sib xyaw nrog compression thiab tensile loads, raws li tau tshaj tawm hauv lub hnab ntawv ua haujlwm.

Qib V3 kua ntsuas + axial loads + kub cycling

Txhua yam kev xeem uas tau txib hauv Qib V4 siv rau V3. Txhawm rau ua tiav V3 daim ntawv pov thawj, tus neeg ntim khoom kuj yuav tsum dhau qhov ntsuas kub ntawm lub voj voog. Nyob rau hauv qhov ntsuas kub ntawm lub voj voog, lub packer yuav tsum tuav lub siab tshaj plaws uas tau teev tseg ntawm qhov kub thiab txias txwv nyob rau hauv uas lub packer yog tsim los ua hauj lwm. Qhov kev ntsuam xyuas yog pib ntawm qhov kub siab tshaj plaws, xws li hauv V4 thiab V5. Tom qab dhau qhov ntu ntawm qhov ntsuas no, qhov ntsuas kub tau tso cai kom txias kom tsawg, thiab lwm qhov kev ntsuas siab raug siv. Tom qab ua tiav qhov kev ntsuas kub qis, tus ntim khoom kuj yuav tsum dhau qhov sib txawv-siab tuav tom qab qhov ntsuas kub ntawm tes tau tsa rov qab mus rau qhov siab tshaj plaws.

Qib V2 roj xeem + axial loads

Tib qhov ntsuas tsis siv hauv V4 siv rau Qib V2, tab sis qhov ntsuas nruab nrab yog hloov nrog huab cua lossis nitrogen. Kev xau tus nqi ntawm 20 cm3 ntawm cov roj hauv lub sijhawm tuav tau txais, txawm li cas los xij, tus nqi yuav tsis nce thaum lub sijhawm tuav.

Qib V1 roj xeem + axial loads + kub cycling

Tib qhov ntsuas tsis siv hauv V3 siv rau Qib V1, tab sis qhov ntsuas nruab nrab yog hloov nrog huab cua lossis nitrogen. Zoo ib yam li V2 xeem, tus nqi xau ntawm 20 cm3 ntawm cov roj hauv lub sijhawm tuav tau txais, thiab tus nqi yuav tsis nce thaum lub sijhawm tuav.

Qib Tshwj Xeeb V0 Gas Test + Axial Loads + Kub Cycling + Bubble Tight Gas Seal Qhov no yog qib tshwj xeeb validation uas tau ntxiv kom ua tau raws li cov neeg siv khoom tshwj xeeb uas yuav tsum tau muaj cov roj foob nruj. Cov kev ntsuas ntsuas yog tib yam li cov rau V1, tab sis tsis tso cai rau cov pa roj pa thaum lub sijhawm tuav.

Yog tias lub hnab ntim khoom tsim nyog rau kev siv qib siab dua, nws yuav pom tau tias tsim nyog rau kev siv hauv ib qho ntawm cov qib qis dua. Piv txwv li, yog tias kuaj rau qib V4, nws raug lees paub tias cov pob khoom ua tau raws li lossis tshaj qhov kev pabcuam ntawm V4, V5, thiab V6 daim ntawv thov.

Vigor's packers yog tsim nyob rau hauv nruj raws li API 11D1 cov qauv, thiab cov khoom zoo ntawm cov khoom tau lees paub los ntawm ntau tus neeg siv khoom thiab tau mus txog kev koom tes ntev nrog Vigor. Yog tias koj txaus siab rau Vigor's packers lossis lwm yam khoom siv rau drilling thiab ua tiav, thov tsis txhob yig tiv tauj peb rau kev txhawb nqa kev tshaj lij.
