Laum dab tshos Connection & Manufacturing Features
Hom xov:Rotary Shouldered Connections (NC, REG, thiab qee zaum IF).
Txias Rolling:Cov hauv paus hniav yog txias- dov rau compress cov hlau thiab ua rau kom qaug zog.
Phosphate Txheej:Cov xov yog phosphated lossis tooj liab-plated los tiv thaivsiab(xov puas) thaum pleev.
Bore Alignment:Precision sib sib zog nqus- qhov tho txawv kom ntseeg tau tias txoj kab uas hla sab hauv (ID) yog nyob nruab nrab kom tswj tau qhov sib npaug thaum sib hloov.
Nthuav Kev Nyuaj Siab Nta:API nyem grooves (Pin) thiab bore backs (Box) feem ntau machined rau hauv kev sib txuas los faib kev ntxhov siab.
Classification los ntawm Surface Design
Slick Drill dab tshos:Ib tug du, uniform cylindrical nto. Siv rau cov qhov dej ntsug thiab cov qauv tsim.
Spiral Drill dab tshos:Nta peb helical grooves machined rau hauv OD.
Spec:Txo qhov chaw sib cuag los ntawm40%.
Lub hom phiaj:Tiv thaivDifferential Stickinglos ntawm kev cia cov av nkos mus ncig ntawm cov yeeb nkab txawm tias nws tau so tawm tsam phab ntsa ntawm lub qhov dej.
Tsis yog -Magnetic Drill Collar:Tsim los ntawm tshwj xeeb siab -Mn, qis-C stainless hlau.
Spec:Sib nqus Permeability μ Tsawg dua lossis sib npaug rau 1.010.
Lub hom phiaj:Tsev MWD/LWD cov cuab yeej los xyuas kom meej cov lus qhia kev nyeem ntawv.

FAQ
Qhov luaj li cas yog ib tug laum dab tshos?
Sab nraud txoj kab uas hla ntawm cov tho dab tshos feem ntau yog li ntawm 3-1 / 8 "mus rau 11" (79.4-279.4 mm), nrog rau qhov ntev tshwj xeeb xaiv raws li lub qhov tsim thiab cov kev xav tau drilling. Tus qauv ntev yog feem ntau 9.15 meters lossis 9.45 meters.
Qhov ntev ntawm lub dab tshos laum yog dab tsi?
Laum dab tshos feem ntau yog 9.15 meters lossis 9.45 meters ntev, uas yog tus qauv tshwj xeeb tsim los ua kom haum nrog cov kav dej tho (kwv yees li 9.14 meters ib leeg), txhim kho kev sib koom ua ke kev sib txuas thiab kev ruaj ntseg hauv qhov chaw.
