Taw qhia
Sucker rodsyog ib qho tseem ceeb ntawm cov khoom siv roj ntau lawm. Lawv yog siv los xa hluav taws xob los ntawm qhov chaw mus rau lub twj tso kua mis downhole, uas nqa cov roj lossis roj rau saum npoo. API 11B yog ib qho kev qhia tshwj xeeb uas tau siv dav hauv kev lag luam roj thiab roj.
Txuj
API 11B qhia txog qhov ntev, kam rau ua, thiab kev ua tau zoo rau cov pas nrig. Tus qauv npog cov hauv qab no:
Khoom siv:API 11B nqus cov pas nrigFeem ntau yog ua los ntawm cov hlau muaj zog, xws li 4130, 4142, lossis 4330.
Qib: Muaj nyob rau hauv ntau qib, txhua tus muaj lub zog sib txawv thiab kev qaug zog tiv thaiv.
Loj: Ntau qhov ntau thiab tsawg, xws li 5/8 "mus rau 1 1/8" inch.
Length: Los ntawm 25' mus rau 30'.
Nqe
Tus nqi ntawmAPI 11B nqus cov pas nrigNws txawv nyob ntawm cov yam ntxwv hauv qab no:
(1) Txuj: API 11B pas nrig feem ntau kim dua lwm hom pas nrig.
(2) Khoom siv
Cov khoom siv los ua nws yog qhov tseem ceeb cuam tshuam rau tus nqi. Cov hlau muaj zog, xws li 4130, 4142, lossis 4330, yog cov khoom siv ntau tshaj plaws siv rau API 11B rods. Cov ntaub ntawv no muaj zog thiab ruaj khov, tab sis lawv kuj tseem kim dua lwm cov ntaub ntawv, xws li cam khwb cia hlau lossis txhuas.
(3) Qib
Nws qib hais txog nws lub zog thiab qaug zog ua haujlwm. Cov pas nrig qib siab yog kim dua li cov khoom qis dua. Qib C yog qib feem ntau rau API 11B rods. Qib D, HL, HY, thiab KD muaj rau cov ntawv thov uas yuav tsum muaj zog dua lossis qaug zog.
(4) Loj
Qhov loj yog hais txog nws txoj kab uas hla. Cov pas nrig loj yog kim dua cov pas nrig me. Qhov no yog vim cov pas nrig loj xav tau cov khoom siv thiab kev ua haujlwm ntau dua los tsim.
(5) Daim ntawv thov
Daim ntawv thov uas tus pas nrig yog npaj tuaj yeem cuam tshuam tus nqi. Qws rau cov khoom siv roj ntau lawm feem ntau kim dua li cov khoom siv rau lwm yam kev siv. Qhov no yog vim cov khoom siv roj ntau lawm yuav tsum tau xav tau ntau dua li lwm yam kev siv.
Tus nqi ntawmAPI 11B nqus cov pas nrignws txawv nyob ntawm ntau yam. Yog tias koj xav tau kev daws teeb meem, thov hu rau peb ntawminfo@vigorpetroleum.com.
