Raws li cov khoom tsim nyog ntawm kev ua haujlwm drilling,drilling stabilizersyog qhov tseem ceeb rau cov roj thiab roj sector. Cov cuab yeej no yog tsim los txo kev vibrations thiab tswj txoj hlua laum txoj hauv kev, uas txhim kho kev ua haujlwm drilling 'kev ua tau zoo, precision, thiab kev nyab xeeb.
Drilling stabilizers Hom
①Integral blade stabilizers: Lawv yog tsim los ua ib daim nrog lub cev thiab cov hniav tsim los ntawm tib yam khoom. Cov stabilizers no tshwj xeeb tshaj yog haum rau cov xwm txheej nyuaj drilling thiab muaj lub neej ntev. Lawv zoo meej rau cov ntawv thov uas xav tau kev hnav zoo heev vim lawv cov qauv tsim muaj zog.
②Replaceable hniav stabilizers: Lawv muaj lub cev nrog cov hniav tshem tau. Qhov no stabilizer tus tsim ua rau nws yooj yim los tswj thiab sib pauv cov hniav uas hnav tsis tas yuav hloov tag nrho. Los ntawm tsuas yog hloov cov hniav, cov stabilizers tuaj yeem raug kho rau ntau qhov ntau thiab tsawg thiab cov ntaub ntawv, ua rau lawv ob qho tib si hloov tau thiab tus nqi tsim nyog.
③ Roller stabilizers: Lawv siv cov khoom sib hloov tsis yog cov hniav ruaj khov. Cov stabilizers yog tshwj xeeb tshaj yog pab tau nyob rau hauv deviated thiab kab rov tav qhov dej vim hais tias lawv tau ua kom tsawg torque thiab kev sib txhuam thaum lub sij hawm drilling. Nyob rau hauv cov formations nyuaj, cov menyuam stabilizers muaj txiaj ntsig zoo rau kev txo cov nplaum nplaum thiab txhim kho tag nrho cov kev ua haujlwm drilling.
④ Lub tes tsho stabilizers: Lwm lub npe rau cov uas tsis yog-rotating stabilizers, yog ua kom nyob rau hauv qhov chaw nyob rau hauv relation mus rau lub borehole phab ntsa txawm thaum lub laum txoj hlua rotates. Cov stabilizers no yog qhov zoo rau kev tsim cov rhiab heev lossis kev ua haujlwm ntev ntev vim tias lawv txo qis hnav thiab kev sib txhuam ntawm phab ntsa borehole. Txhua hom stabilizer muaj cov yam ntxwv tshwj xeeb thiab ua haujlwm zoo tshaj plaws hauv cov xwm txheej tshwj xeeb.
Txoj Cai Ua Haujlwm
Lub luag haujlwm tseem ceeb ntawmdrilling stabilizersyog tswj kev xyaum txoj hlua vibration thiab tswj qhov xav tau laum me ntsis trajectory. Lawv ua tiav qhov no los ntawm ntau yam mechanisms:
◆ Kev tswj kev vibration: Stabilizers ua raws li cov ntsiab lus hauv nruab nrab ntawm txoj hlua xyaum, txo qis kev txav mus los thiab txo qis kev puas tsuaj. Los ntawm kev muab ntau cov ntsiab lus sib txuas nrog cov phab ntsa borehole, stabilizers pab faib cov load thiab dampen vibrations uas tuaj yeem ua rau cov cuab yeej ua tsis tiav ntxov lossis lub qhov tsis zoo.
◆ Kev saib xyuas txoj hauv kev: Stabilizers ua lub luag haujlwm tseem ceeb hauv kev tswj lub laum me ntsis thiab tswj txoj hauv kev uas xav tau. Los ntawm kev ua haujlwm zoo ntawm txoj hlua laum hauv qhov borehole, stabilizers pab tiv thaiv qhov nyiam ntawm txoj hlua xyaum kom sib txawv ntawm qhov kev npaj ua haujlwm vim muaj kev cuam tshuam los yog lub ntiajteb txawj nqus.
◆ Hloov qhov hnyav: Stabilizers pab hloov qhov hnyav ntawm txoj hlua laum mus rau me ntsis zoo dua. Qhov kev hloov pauv qhov hnyav no pab tswj qhov hnyav ntawm me ntsis (WOB), ua rau kom zoo dua ntawm kev nkag mus (ROP) thiab tag nrho kev ua haujlwm drilling.
◆ Qhov zoo ntawm lub qhov dej: Los ntawm kev tuav cov hlua tho qhov nruab nrab, cov stabilizers pab txhawb kev tsim cov borehole zoo dua, zoo dua qub. Qhov kev txhim kho qhov zoo no tuaj yeem ua rau kom cov cementing zoo dua thiab ua haujlwm yooj yim dua.
Txoj hauj lwm ntawm Drilling stabilizers hauv Drilling String
◆ Nyob ze-ntsis stabilizer: Muab tso rau tam sim ntawd saum lub laum me ntsis, qhov stabilizer no pab tswj me ntsis qaij thiab txhim kho qhov hnyav hloov mus rau me ntsis. Nws plays lub luag haujlwm tseem ceeb hauv kev tswj cov kev taw qhia thiab txo qis me ntsis wobble.
◆String stabilizers: Cov no tau muab tso rau ntawm qhov kev sib tw zoo raws li txoj hlua tho kom muab kev txhawb nqa ntxiv thiab txo qis tag nrho txoj hlua deflection. Lawv qhov kev tso kawm yog ua tib zoo xam los ua kom zoo dua qhov kev xyaum ua txoj hlua dynamics thiab kev tu lub qhov.
◆Rotary steerable system (RSS) stabilizers: Nyob rau hauv cov kev taw qhia drilling daim ntawv thov siv RSS, tshwj xeeb stabilizers tau koom ua ke rau hauv lub cev los txhim kho lub peev xwm thiab tswj kev ruaj ntseg zoo.
Cov kev npaj tshwj xeeb ntawm stabilizers nyob ntawm ntau yam, nrog rau qhov zoo profile, tsim cov yam ntxwv, thiab lub hom phiaj drilling. Piv txwv li, nyob rau hauv ntsug drilling, tusyees spaced stabilizers yuav siv tau los tuav lub qhov ncaj. Nyob rau hauv kev taw qhia drilling, lub stabilizer configuration yuav raug kho los tsim ib tug fulcrum nyhuv, ua kom yooj yim rau qhov xav tau sib txawv.
