1. Lub hauv paus ntsiab lus
Qhov rov qab tau tshauv-squeezing choj txuas muaj lub rooj sib khi thiab thauj tog rau nkoj mechanism, lub xauv thiab unsealing mechanism, zawv zawg lub tes tsho hloov thiab ib qho kev tiv thaiv nplaum, ib qho intubation thiab khaws cia mechanism.
Cov cuab yeej teeb tsa hluav taws xob lossis roj yeeb nkab hydraulic qhov chaw tuaj yeem siv los xa cov txuas txuas txuas mus rau qhov chaw ua ntej rau kev teeb tsa thiab muab pov tseg, tom qab ntawd tshem tawm qhov chaw thiab cov cuab yeej pub mis, ntxig cov cuab yeej intubation rau hauv qhov rov qab tau tshauv squeezing choj ntsaws, thiab ua haujlwm ntawm cov tshauv squeezing, Tom qab nyem cov tshauv, tsa lub intubation raj thiab rov qab ntxuav lub qhov dej.Tom qab pib qhov chaw ntawm lub mortar, lub overshot tuaj yeem raug txo kom ntses tawm ntawm tus choj ntsaws.
2. Cov txheej txheem ua haujlwm
1. Kev teeb tsa thiab kev ua haujlwm tsis sib khi yog tib yam li kev sib khi ua ke.
2.Tom qab cov hmoov tshauv-squeezing choj ntsaws yog teem, txuas cov tshauv-squeezing cannula mus rau hauv qab ntawm lub tubing hlua thiab txo nws mus rau hauv lub wellbore, ntxig rau nws mus rau hauv lub mandrel ntawm lub rov qab-hom tshauv-squeezing choj plug, thiab thawb. lub swb valve.
3.Hloov cov cement slurry nrog lub tsheb cement rau cov hmoov tshauv squeezing.
4.Tom qab cov tshauv yog nyem, tam sim ntawd nqa cov yeeb nkab hlua, rub tawm cov yeeb nkab intubation los kaw lub swb valve, thiab tam sim ntawd rov qab ntxuav lub qhov dej kom ntxuav cov cement mortar ntau dhau ntawm lub qhov dej.Vim tias qhov swb valve raug kaw, cov cement slurry sab nraum qhov tsim los yog cov yeeb nkab tsis tuaj yeem ntws rov qab mus rau hauv qhov dej, uas ua kom cov cementation zoo thiab ntsaws cov nyhuv ntawm cov cement slurry, shortens lub sij hawm nyob ntawm cov cement slurry nyob rau hauv qhov dej, thiab txo. cov cement slurry solidification yeeb nkab hlua.
5.Yog tias cov txheej txheem sab saud raug siv, Retrievable Choj Plug ntawm Cement Squeeze yog siv los ua ib qho txuas txuas txuas txuas thiab tuaj yeem muab tso rau hauv kev tsim khoom ncaj qha;Yog hais tias cov txheej hauv qab yog mined, cov hlua khi tsis tau muab tso rau hauv qhov dej kom tshem tawm cov choj ntsaws.Tom qab tus choj txuas tau rub tawm, muab cov khau sib tsoo hauv lub qhov dej kom tho tawm cov cement ntsaws.Txij li thaum tsis muaj hlau qhov chaw, drilling thiab sib tsoo yog ib qho yooj yim.
3. Technical nta
1. Txoj kev teeb tsa yooj yim: Lub choj txuas tuaj yeem xa mus rau hauv qhov chaw los ntawm cov khoom siv cable-hom chaw lossis cov cuab yeej hydraulic, thiab cov cuab yeej tsim nyog tuaj yeem xaiv tau raws li qhov tshwj xeeb ntawm qhov dej.
2. Kev tswj xyuas qhov tseeb: Qhov chaw quab yuam ntawm tus choj ntsaws yog tswj los ntawm qhov nro pas nrig (ntiv nplhaib), uas ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm tus choj ntsaws.Nyob rau tib lub sijhawm, nws ua kom ntseeg tau tias cov cuab yeej teeb tsa tuaj yeem raug tshem tawm ntawm lub qhov dej hauv qhov chaw nyuaj.
3. Txhim khu kev ruaj ntseg los tiv thaiv jamming tsim: Lub hauv pliaj ib feem tau txais cov qauv hauv kev ua haujlwm, thiab tus choj ntsaws tsis yooj yim los ntsib kev tiv thaiv thiab jamming thaum nws yog lifted thiab txo qis hauv cov ncej.Tom qab teeb tsa, tus choj ntsaws ntsaws thiab lub raj roj hmab yog qhov nruab nrab, thiab tuaj yeem siv tau zoo nyob rau hauv qhov dej nrog txhua qhov inclination thiab kab rov tav qhov dej.
4. Cov txheej txheem tshwj xeeb anchoring: tus choj txuas siv kev sib xyaw ua ke ntawm cov hlais, cov kab nrib pleb, thiab cov cylinders sab nraud.Nws muaj peev xwm zoo bidirectional siab bearing thiab tuaj yeem siv rau cov casings ntawm ntau qib.
5. Safe unsealing mechanism: Lub unsealing ntawm tus choj ntsaws yog ua los ntawm cov kauj ruam nyob rau hauv qhov kev txiav txim ntawm lub xauv mechanism, lub sealing mechanism, thiab plam mechanism.Txawm hais tias lub siab thiab qis qis ntawm tus choj ntsaws yog sib npaug, qhov yuav tsum tau muaj zog unsealing tsawg heev.
6. Nws yog ib qho yooj yim rau laum thiab zom cov hmoov tshauv ntsaws: tom qab cov hmoov tshauv squeezing lub lag luam ntawm cov ntoo tshauv-squeezing choj plug, tus choj ntsaws tuaj yeem rub tawm, thiab nws yooj yim rau laum thiab zom cov hmoov tshauv ntsaws.
7. Muaj qee yam drillability: tus choj plug muaj cov qauv compact, lub sab sauv qauv yog ua los ntawm cov ntaub ntawv nrog zoo drillability, thiab lub internal locking mechanism yog nyob rau sab saum toj ntawm tus choj plug, txawm yog hais tias tus choj plug tsis tau fished tawm vim vim li cas txawv txav, nws tseem tuaj yeem yooj yim rau kev xyaum.
