Sab hauv kev ua haujlwm ntawm Drilling Equipment li qub: Kev tswj xyuas thiab kev nyab xeeb

Qhia:

Nyob rau hauv lub complex ntiaj teb nocov khoom siv drilling , ntau yam tseem ceeb ua hauj lwm seamlessly ua ke los xyuas kom meej kev ua haujlwm du. Ntawm lawv, li qub ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej ntws, tswj lub siab, thiab txawm tswj cov xwm txheej kub ntxhov. Qhov blog no yuav saib xyuas qhov tob ntawm cov tshuab thiab kev ua haujlwm ntawm li qub, nrog rau qhov tshwj xeeb ntawm lawv qhov tseem ceeb hauvwellheads thiab tswj zoo.

Valves hauv cov khoom siv drilling:

Lub valve yog cov cuab yeej siv los tswj cov dej ntws, roj lossis slurry. Hauv cov khoom siv drilling, lawv yog qhov tseem ceeb rau kev tswj cov dej ntws ntawm cov av nkos, cov kua tshwj xeeb uas pab hauv kev ua haujlwm drilling. Cov noli qub raug rau huab cua siab, kub siab thiab corrosive tshuaj; Yog li ntawd, lawv yuav tsum tau ruaj, txhim khu kev qha thiab tiv taus hnav thiab tsim kua muag.

Lub taub hau thiab li qub:

Cov cuab yeej Wellhead yog ib feem tseem ceeb ntawm qhov chaw ntawm cov roj lossis roj qhov dej thiab muab qhov tsim nyog tswj xyuas thaum drilling. Ntawm lub taub hau dej, li qub ua lub luag haujlwm tseem ceeb hauv kev tswj hwm thiab tiv thaiv kev puas tsuaj los yog tsis muaj kev tswj hwm kev tso tawm ntawm hydrocarbons. Ob hom li qub feem ntau siv rau hauv lub qhov taub yog "qhov rooj li qub" thiab "qhov valves."

1. Rooj vag valve:

Arooj vag valve yog linear motion valve uas qhib los ntawm kev nqa lub rooj vag tawm ntawm cov kua dej ntws. Nws muab kev tswj xyuas zoo ntawm / tawm ntawm lub qhov dej thiab feem ntau yog siv thaum lub sijhawm drilling. Lub rooj vag li qub yog tsim los tiv thaiv kev kub ntxhov thiab tiv thaiv cov kua dej rov qab. Lawv feem ntau nyob hauv qab ntawm lub qhov dej thiab ua qhov cuam tshuam rau txhua qhov kev npaj txhij txog surges.

2. Throttle valve:

Acaj npab valve , tseem hu ua lub valve tswj, pab txwv thiab tswj cov dej ntws los ntawm lub qhov dej. Nws tuaj yeem ua haujlwm nyob rau hauv ntau txoj haujlwm kom tswj tau qhov xav tau ntws thiab siab thaum lub sijhawm drilling. Hom valve no ua lub luag haujlwm tseem ceeb hauv kev txo cov xwm txheej tswj tau zoo, tiv thaiv kev kub ntxhov ntau dhau, thiab tiv thaiv cov cuab yeej tsis ua haujlwm.

Zoo tswj thiab Valve muaj nuj nqi:

Kev tswj xyuas zoo yog cov txheej txheem ntawm kev tswj xyuas lub siab thiab cov dej ntws tsis pub dhau kev txwv kev nyab xeeb thaum lub sijhawm ua haujlwm drilling. Ntawm no, lub valve tuaj rau hauv kev ua si kom ua tiav ob lub luag haujlwm tseem ceeb:

1. Blowout Preventer (BOP) valve:

BOP li qub tau suav hais tias yog kab kawg ntawm kev tiv thaiv tiv thaiv tsis muaj kev tswj hwm. Cov li qub no tau teeb tsa saum lub qhov dej, muab kev nyab xeeb ntxiv. Lawv thaiv cov roj qhov dej thaum muaj xwm txheej ceev, tiv thaiv kom tsis txhob tawg. Hydraulic actuators tuaj yeem kaw lub tshuab hluav taws xob tiv thaiv lub valve kom cais lub qhov dej ntawm cov khoom siv saum npoo av.

2. Annular blowout tiv thaiv valve:

Annular BOPs siv cov elastomeric hloov tau yooj yim los kaw qhov chaw nruab nrab ntawm cov yeeb nkab laum thiab lub qhov dej. Cov li qub no pab tswj lub siab thiab tseem ceeb heev rau kev tswj xyuas kev ua haujlwm zoo, feem ntau thaum drilling thiab ua tiav cov haujlwm.

Hauv kev xaus:

Valves hauv cov khoom siv drilling, tshwj xeeb tshaj yog nyob rau hauv lub taub hau thiab kev tswj kom zoo, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib tsoo, tswj kom muaj lub siab xav tau thiab tswj cov dej ntws. Nkag siab txog nws txoj haujlwm thiab ua kom ntseeg tau tias nws yog qhov tseem ceeb rau kev nyab xeeb thiab ua haujlwm zoo drilling. Raws li kev siv thev naus laus zis txuas ntxiv mus, cov li qub yuav tsis ntseeg tau txuas ntxiv mus ntxiv kom muaj kev tswj hwm ntau dua, kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
