Yuav ua li cas xaiv thiab tswj cov roj laum yeeb nkab?

Roj laum yeeb nkab yog ib qho tseem ceeb hauv cov roj drilling, thiab nws cov kev xaiv thiab kev saib xyuas yog qhov tseem ceeb rau kev ua tiav thiab kev nyab xeeb ntawm kev ua haujlwm drilling. Cov hauv qab no yuav qhia ob peb lub ntsiab lus tseem ceeb hauv kev xaiv thiab kev saib xyuas cov kav dej tho roj.

Xaiv cov roj laum yeeb nkab

1.Material xaiv: Petroleum laum kav feem ntau yog ua los ntawm high-strength alloy steel, uas carbon steel, alloy steel thiab stainless hlau yog cov kev xaiv. Xaiv cov khoom tsim nyog raws li qhov chaw ua haujlwm thiab xav tau.

2.Qhov yuav tsum tau muaj zog: Txiav txim siab lub zog yuav tsum tau ua ntawm lub laum yeeb nkab raws li qhov tsis xws li drilling qhov tob, qhov zoo inclination, thiab txoj kab uas hla. High-strength steel yuav ua rau kom lub load-bearing muaj peev xwm ntawm lub laum thiab ncua lub neej kev pab cuam ntawm lub laum yeeb nkab.

3.Drill yeeb nkab specifications: Txoj kab uas hla thiab ntev ntawm lub laum yeeb nkab yuav tsum tau txiav txim raws li qhov yuav tsum tau qhov tob tob thiab zoo hom. Feem ntau hais lus, qhov tob tob yuav tsum muaj txoj kab uas hla loj dua thiab cov kav dej ntev dua.

4.Corrosion resistance: Drilling operations feem ntau koom nrog qee yam corrosive, xws li dej ntsev, kua qaub, thiab lwm yam, yog li lub laum yeeb nkab yuav tsum muaj kev tiv thaiv corrosion zoo kom ntev nws lub neej kev pab cuam.

Roj laum yeeb nkab tu

1.Kev ntxuav thiab tiv thaiv xeb: Cov kav dej laum yuav raug corroded los ntawm cov av nkos, roj thiab lwm yam khoom siv thaum siv. Yog li ntawd, lawv yuav tsum tau ntxuav nyob rau hauv lub sij hawm tom qab siv los tiv thaiv kev puas tsuaj rau lub laum yeeb nkab los ntawm residual tshuaj, thiab kev kho los tiv thaiv xeb yuav tsum tau nqa tawm.

2 Kev tshuaj xyuas thiab kho: Tsis tu ncua xyuas cov yeeb nkab laum thiab kho lossis hloov nws raws sijhawm yog tias pom muaj kev puas tsuaj, tawg thiab lwm yam teeb meem. Tshwj xeeb tshaj yog rau qhov txuas threaded ib feem, xyuam xim rau kev soj ntsuam kom tsis txhob muaj teeb meem xws li roj to thiab dethreading.
3. Lubrication thiab txij nkawm: Lub threaded txuas ib feem ntawm lub laum yeeb nkab yuav tsum tau greased tsis tu ncua kom muaj lubrication zoo. Tsis tas li ntawd, cov kav dej laum yuav tsum tau khaws cia tsis tu ncua los tiv thaiv corrosion thiab oxidation.
4. Kev ntsuam xyuas lub zog: tsis tu ncua kev ntsuas lub zog ntawm cov kav dej laum kom ntseeg tau tias lawv yuav tsis raug cov yas deformation lossis tawg thaum ua haujlwm.
