Packers tuaj yeem muab faib ua peb hom: mechanical set, hydraulic set, thiab packers mus tas li.
Mechanical set packers yog teem siv tubing txav, xws li kev sib hloov los yog upward/downward motion. Lawv raug tso tawm los ntawm ib txoj hlua rub yooj yim thiab tsim nyog rau qhov dej ntiav, tsis tshua muaj siab.
Tension-set packers yog teem los ntawm rub nro ntawm lub raj, thiab tso cov nro tso tawm lub packer. Lawv tau siv hauv qhov dej ntiav nrog qhov sib txawv nruab nrab thiab feem ntau ua haujlwm hauv kev ua haujlwm stimulation.
Kev sib hloov-teeb packers yog teem los ntawm tubing rotation, qhov twg ib tug sab laug-tes tig packer thiab ib tug sab tes xis tig retrieves nws.
Hydraulic-set packers siv cov dej siab los tsav lub khob hliav qab ntawm cov ntawv hlais, thiab lawv nyob twj ywm los ntawm kev nkag siab los yog lub tshuab ntsuas phoo. Lawv raug tso tawm los ntawm kev khaws cov tubing thiab muaj txiaj ntsig zoo nyob rau hauv qhov sib txawv los yog nkhaus qhov uas cov tubing txav tau txwv.
Inflatable packers siv cov kua dej siab los ua kom lub raj roj hmab ntxiv thiab teeb tsa lub ntim khoom. Lawv feem ntau siv rau hauv qhov qhib qhov ntsuas thiab kev ruaj ntseg cement, tshwj xeeb tshaj yog nyob rau hauv qhov dej nrog kev txwv.
Cov packers tas mus li yog teem rau hluav taws xob xaim, laum yeeb nkab, lossis tubing. Lawv tau tawm tsam cov ntawv hla tebchaws uas kaw lub pob ntim hauv compression thiab tiv taus kev txav mus los ntawm ob qho tib si. Wireline packers siv hluav taws xob tam sim no los teeb tsa lawv, thaum lub thawv ntim khoom tuaj yeem teeb tsa los ntawm kev sib hloov lossis rub. Lawv haum rau cov qhov dej uas muaj qhov sib txawv siab los yog loj tubing load variations.
Cement packers koom nrog cementing cov tubing nyob rau hauv qhov chaw hauv lub casing los yog qhib qhov.
