Cov khoom
Ib-pass Combined Hom Cement Retainer
Kev siv tseem ceeb
ZPO - 110
Ib qho kev sib xyaw ua ke Cement Retainer feem ntau yog siv rau ib ntus thiab mus tas li ntsaws lossis cov cementing theem nrab ntawm cov roj, roj thiab dej txheej. Cov cement slurry yog nyem rau hauv qhov chaw annular los ntawm qhov tuav thiab yuav tsum tau muab kaw. Cov seem cemented zoo los yog cov pob txha thiab cov pores nkag mus rau hauv kev tsim yog siv los ua kom tiav lub hom phiaj ntawm kev ntsaws thiab kho cov xau.
Qauv thiab Txoj Cai Ua Haujlwm
Qauv:
Nws muaj cov txheej txheem kev teeb tsa thiab kev tuav pov hwm.
Txoj Cai Ua Haujlwm:
Teem lub foob: Thaum cov roj yeeb nkab yog pressurized rau 8-10MPa, tus pin pib raug txiav tawm, thiab ob-theem piston thawb lub tog raj kheej thawb rau hauv lem, thiab tib lub sij hawm ua rau lub sab sauv, lub khob hliav qab, roj hmab raj. thiab lub khob hliav qab qis qis, thiab lub zog tsav tsheb mus txog li ntawm 15T, tom qab kev teeb tsa tiav, tus pin poob raug txiav tawm kom paub tias poob. Tom qab cov tes poob lawm, cov yeeb nkab hauv nruab nrab tau rov ua dua rau 30-34Mpa, lub pob lub rooj zaum tus pin txiav tawm cov roj yeeb nkab kom tso tawm lub siab, thiab lub rooj zaum pob poob mus rau lub pob tawb tau txais, thiab tom qab ntawd cov yeeb nkab kab yog nias. poob los ntawm 5-8T. Cov roj yeeb nkab yog pressurized rau 10Mpa thiab yog nyem los xyuas lub foob, thiab nws yuav tsum tau nqus dej thiab nyem qhov txhaj tshuaj.
Cov kev ceev faj
①Txoj hlua cov yeeb nkab no tsis raug tso cai los txuas cov cuab yeej bypass sab nraud.
②Qhov kev teeb tsa cov pob hlau tsis raug tso cai rau preset, thiab qhov drilling ceev yog nruj me ntsis txwv tsis pub lub siab los ntawm kev ceev ntawm drilling ntau dhau, kom cov txheej txheem nruab nrab tuaj yeem teeb tsa.
③ Scraping thiab yaug dej yuav tsum tau ua rau thawj zaug ua haujlwm kom ntseeg tau tias cov phab ntsa sab hauv ntawm lub casing tsis muaj nplai, xuab zeb thiab cov khoom, kom tiv thaiv kev teeb tsa tsis ua haujlwm los ntawm cov xuab zeb thiab cov khoom thaiv cov channel ntawm cov cuab yeej teeb tsa. ④ Tom qab qhov kawg ntawm qhov tuav tau raug nyem, yog tias qhov kawg yuav tsum tau nyem, sab sauv kawg ntawm tus tuav yuav tsum tau nyem tom qab cov cement ntawm qhov qis kawg yog solidified.
Technical nta
1. Qhov chaw thiab extrusion ntawm cov yeeb nkab hlua yog ua tiav nyob rau hauv ib lub sij hawm, uas yog ib qho yooj yim rau kev khiav lag luam thiab muaj ib tug me me workload. Tom qab kev ua haujlwm extrusion, qhov qis tuaj yeem raug kaw.
2. Kev qhib tsim ntawm lub raj intubation thiab qhib tsim ntawm cov cement retainer tuaj yeem tiv thaiv kev thaiv cov xuab zeb thiab av, thiab tiv thaiv kev hloov ntawm kev ua haujlwm tsis zoo.
