Pup pob qij txhayog ib hom tubular khoom siv nyob rau hauv cov roj thiab roj drilling thiab kev ua haujlwm ntau lawm. Lawv yog cov ntev ntev ntawm cov yeeb nkab, feem ntau yog li ntawm 2 ko taw mus rau 10 ko taw ntev, uas yog siv los ua kom muaj qhov sib txawv ntawm qhov ntev thaum sib sau cov ntu ntev ntawm cov yeeb nkab lossis cov kav dej.
Nws tau txais nws lub npe los ntawm qhov tseeb tias lawv luv dua li "niam txiv" cov pob qij txha ntawm cov yeeb nkab laum los yog casing uas ua rau feem ntau ntawm cov hlua. Zoo li tus menyuam dev me me dua li tus dev loj hlob, qhov sib koom ua ke luv dua li qhov ntev 30-40 ko taw ntev ntawm cov yeeb nkab.
Ntev npaum li cas Pup Joint?
Raws li tau hais los saum no, nws feem ntau luv luv, txij li 2 ko taw (24 ntiv tes) mus txog 10 feet ntev. Txawm li cas los xij, tsis muaj qhov ntev ntev. Lawv tau tsim nyob rau hauv ntau qhov ntau thiab tsawg los muab qhov ntev ntev uas yuav tsum tau ua kom muaj qhov ntev ntawm cov yeeb nkab uas xav tau rau ib daim ntawv thov tshwj xeeb.
◆ Qee qhov ntev tshaj plaws yog:
- 2 ko taw (24 ntiv)
- 3 ko taw (36 ntiv)
- 5 ko taw (60 ntiv)
- 10 ko taw (120 ntiv)
Qhov ntev yuav tsum tau nyob ntawm tag nrho qhov ntev ntawm txoj hlua laum los yog cov hlua casing tau sib sau ua ke thiab cov qauv ntev ntawm cov pob qij txha siv tau. Cov pob qij txha pab cov drillers ua tiav txoj hlua ntev uas xav tau thaum cov pob qij txha ib leeg yuav ua rau qhov ntev me ntsis luv dua li qhov zoo.
Pup Joint luj
Nws qhov hnyav nyob ntawm nws qhov loj - ntev, sab nraud txoj kab uas hla, thiab phab ntsa thickness. Cov pob qij txha me me tuaj yeem hnyav 100 phaus lossis tsawg dua. Cov pob qij txha loj uas siv hauv qhov tob tob yuav hnyav 2,000 phaus lossis ntau dua.
Feem ntau, lawv yog tsim los ntawm tib qib ntawm cov yeeb nkab steel raws li tus qauv laum yeeb nkab thiab casing pob qij txha. API qib yeeb nkab yog feem ntau. Cov yeeb nkab tsuas yog txiav kom luv luv. Yog li ntawd, phab ntsa thickness thiab cov khoom siv zog yog tib yam li kev sib koom ua ke.
Qhov hnyav ib ko taw ntawm steel laum yeeb nkab thiab casing nce nrog cov yeeb nkab loj dua thiab cov phab ntsa thicknesses. Daim ntawv qhia kwv yees rau qhov hnyav ib ko taw ntawm qhov ntau thiab tsawg ntawm oilfield yeeb nkab yog:
- 2 3/8" OD laum yeeb nkab - nyob ib ncig ntawm 9 lbs/ft
- 4 1⁄2" OD laum yeeb nkab - nyob ib ncig ntawm 19 lbs/ft
- 5 1⁄2" OD casing - nyob ib ncig ntawm 29 lbs/ft
- 7" OD casing - nyob ib ncig ntawm 49 lbs/ft
Yog li ib 5-ko taw sib koom ntawm 5 1⁄2" casing yuav hnyav ib ncig ntawm 145 phaus (5 x 29 lbs/ft). Thaum ib tug 10- ko taw ntev ntawm tib qhov loj yuav yog ob npaug. hnyav nyob ib ncig ntawm 290 phaus.
Nws qhov hnyav yuav tsum raug coj mus rau hauv tus account thaum tsim cov hlua tho thiab cov hlua khi kom ntseeg tau tias tag nrho qhov hnyav tsis tshaj crane nqa lub peev xwm thiab tiv thaiv kev ntxhov siab ntau dhau ntawm cov yeeb nkab sib txuas.
Pup Joint Sizes
Cov pob qij txha muaj nyob rau hauv ntau yam ntawm sab nraud diameters thiab phab ntsa thicknesses kom phim cov specifications ntawm tus qauv laum yeeb nkab thiab casing qhov ntau thiab tsawg. Qee qhov loj tshaj plaws yog:
◆ Drill Pipe Pup Joints:
- 2 3/8" OD
- 2 7/8" OD
- 3 1⁄2" OD
- 4" OD
- 4 1⁄2" OD
- 5" OD
◆ Casing Joints:
- 4 1⁄2" OD
- 5" OD
- 5 1⁄2" OD
- 6 5/8" OD
- 7" OD
- 8 5/8" OD
- 9 5/8" OD
Lub laum yeeb nkab thiab casing siv nyob rau hauv ib tug muab qhov dej yuav dictate lub sab kab thiab qib uas yuav tsum tau rau tej pob qij txha. Cov kev cai luv luv tuaj yeem tsim tau raws li qhov xav tau rau cov ntawv thov tshwj xeeb. Nws qhov kawg yog threaded kom tso cai rau kev sib txuas rau cov pob qij txha tsis tu ncua.
Pup pob qij txhayog cov ntu luv ntawm tubular steel yeeb nkab siv hauv kev lag luam roj kom ua tiav qhov ntev ntev thaum ua cov hlua tho thiab cov hlua casing. Xav tau kev cai pob qij txha rau koj tom ntej drilling lossis ua tiav txoj haujlwm? Peb cov khoom yog tsim los rau cov qauv siab tshaj plaws thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg kom phim koj cov specifications. Txawm hais tias koj xav tau luv luv 2 ft pob qij txha lossis ntev 10 ft ntev, peb tuaj yeem muab qhov ntev npaum li cas koj xav tau los kho koj cov hlua hlua, Thov koj xav tiv tauj peb ntawminfo@vigorpetroleum.com.
