Kev tswj hwm profile thiab dej plugging tus neeg sawv cev

Nws yog qhov siab - molecular - qhov hnyav tshuaj ua los ntawm kev hws - polymerization ntawm cov tshuaj tiv thaiv tsawg - molecular - cov tshuaj hnyav. Cov feem ntau siv thermosetting resins suav nrog cov khoom siv phenolic suav nrog Resin Phenolic, epoxy cob, epea - formaldehyde cob, thiab lwm yam.

Nws tuaj yeem raug txhaj rau cov hws tsim thiab muaj lub zog txaus los thaiv cov hws, pob txha av pob txha av, qhov, channel thiab perforations. Tom qab kho, lub resin yog nruab nrab thiab tsis hnov ​​mob nrog cov dej downhole, yog li lub sijhawm zoo yog ntev. Txawm li cas los xij, tus nqi yog qhov siab thiab nws yog tsis yog - xaiv. Nws feem ntau yog txwv rau hauv lub vojvoog ntawm 30 cm nyob ib ncig ntawm hauv qab ntawm lub qhov dej. Ua ntej siv, lub tsev ntug kev kho mob yuav tsum tau kuaj thiab cais. Ua ntej kho, lub resin yog rhiab rau cov pa phem ntawm dej, surfactants, alkalis thiab acids.

Raws li cov kev sib txawv ntawm cov duab sib txawv thiab kev tswj hwm qhov hnyav, tus neeg sawv cev ntawm kev ncua ntev, uas tuaj yeem sib txuas, ua ntej hla kev sib txuas, thiab kev sib txuas ntxiv.
