Isetshenziselwani I-Sucker Rod?

A induku yokuncelaisetshenziselwa ukudlulisa ukunyakaza nokulayisha ukusuka kudrayivu engaphezulu kuya empompini ye-downhole kusistimu{0}}yokuphakamisa. Endongeni-empontshwa kahle, intambo yenduku iye phezulu naphansi ngaphakathi kweshubhu bese ishayela i-pump plunger, ephakamisa uketshezi olukhiqiziwe luye phezulu. Ngalowo mqondo, induku ayiyona nje insimbi emthonjeni; iyisixhumanisi esisebenzayo phakathi kweyunithi yokumpompa phezulu kanye nepompo engezansi. I-SLB ichaza intambo ye-rod njengokuxhumana phakathi kwesistimu engaphezulu kanye nepompo ye-downhole, futhi iphawula ukuthi ama-rod-amasistimu amaphampu ahlala engenye yezindlela ezivame kakhulu zokwenziwa{6}}zokuphakamisa emithonjeni kawoyela.

Ekusetshenzisweni kwendawo yamafutha,ukukhetha induku ye-suckerkusekelwe kokungokoqoborod-umsebenzi weyunithi yezinhlamvu. Okuguquguqukayo okubalulekile kuhlanganisaukujula kwesilungiselelo sephampu, usayizi weshubhu, usayizi wephampu, umthamo wamanzi, umthwalo wenduku ophucuziwe, ubude be-stroke, imivimbo ngomzuzu, futhiizinga lokukhiqiza eliqondiwe. Umklamo nawo kufanele ucabangeleukuchezuka kahle, ukuxhumana namashubhu, igesi-isilinganiso soketshezi, isihlabathi, upharafini, isikali, kanye nemidiya ezonakalisayo njengeCO2futhiH2S. Lezi zici zinquma ukuthi iyunithi yezinhlamvu kufanele ibe yini-ububanzi obubodwanomatapered, okuthiibanga lendukufuthiububanzikufanele isetshenziswe, noma ngabe aphezulu-induku yamandlakuyadingeka, futhi kanjaniukuhlanganafuthiiponi izindukukufanele ifaniswe.

Ekuphakanyisweni kwenduku okuphindaphindayo, intambo ye-sucker rod iguqula ukunyakaza okuphindaphindayo okungaphezulu kube ukunyakaza kwepompo ye-downhole. Iyunithi ye-beam iphakamisa futhi yehlise intambo; i-pump plunger ilandela lokho kunyakaza futhi ihambisa uketshezi ngeshubhu. Kusevisi ye-PCP, intambo ye-rod futhi iyilungu le-torque{2}}yokudlulisela, ngakho ayisebenzi kuphela ku-axial tension. Yingakho ukukhetha kwenduku kungenakuhlukaniswaimodi yokumpompa, kahle geometry, futhiumjikelezo wokulayisha.

Landa:Standard vs High Strength Sucker Rod Reference

Umehluko awukona nje ukuthi induku eyodwa "inamandla." Umehluko owusizo kakhulu uyasebenza: izinduku ezijwayelekile ngokuvamile zanele kusevisi evamile yokuphindaphinda, kuyilapho{1}}izinduku zamandla eziphakeme zikhethwa lapho iyunithi yezinhlamvu kufanele iphile.umthwalo ophezulu, ukukhathala okukhulu, i-torque eyengeziwe, noma i-geometry efunwa kakhulu.

Isevisi ye-sucker rod kufanele iqondwe ngomsebenzi wangempela womthombo kunokuba ngamalebula embonini abanzi.Ekusebenzeni kwenkambu, iyunithi yezinhlamvu zenduku ikhethwa ngokumelene nethizeindlela yokumpompa, ukujula kahle, umthamo wamanzi, kahle trajectory, futhiiphrofayili yokugqwalakomthombo. Umbuzo wobunjiniyela awukona nje ukuthi umthombo ukhiqiza uwoyela, kodwa ukuthi intambo yenduku isebenza ngaphansi kwayoumthwalo obuyiselayo, umthwalo we-torsional, ukulayisha okuseceleni kusuka ekuphambukeni, uketshezi oluphezulu-isisindo sekholomu, noma isistimu ye-fluid ekhiqizwa amakhemikhali{0}enamandla. Leyo mibandela inquma ukuthi iyunithi yezinhlamvu kufanele ihlale ngaphakathi kwemvilophu yezinga le-API evamile noma iye kwehlukileinduku ububanzi, i-string taper, ikilasi lokuhlanganisa, noma-uchungechunge lwenduku yamandla aphezulu.

Ama-sucker rod avame ukusetshenziswa ezimweni zemithombo elandelayo:

Izibonelo zenkambu ezimbalwa zenza umqondo wesevisi ucace kakhudlwana:

• Phakathi kuokujulile kuphendulana kahle, izingxenye zenduku engenhla zibona okuphindaphindiwehigh tensile umthwalokuwo wonke ama-stroke. Kulesi simo, ukukhathazeka kokuklama akukona nje amandla okuqamba amagama, kodwa futhiimpilo yokukhathala ekuxhumekeni okucasulayo nokwentambo, ukuhlanganisa ubuqotho, nokuthi i-string taper igcina-ingcindezi ephezulu yeyunithi yezinhlamvu ngaphakathi kwebanga elamukelekayo.
• Phakathi kuwaphambuka kahle, intambo ingase ingahlali igxile kushubhu.Ukuhlanganiswa kwe-ODingathinta udonga lwamashubhu, futhi intambo yenduku engezansi ingase ihambe iye ekucindezelekeni engxenyeni ye-stroke. Ngaphansi kwalezo zimo,ama-sinker bar, ama-stabilizer bar, imihlahlandlela yezinduku, nokukhetha kokuhlanganisayo kuba yingxenye-yesu lokulawula ukugqokwa kunezinsiza ozikhethela zona.
• Phakathi kuPCP kahle, intambo yenduku ayisebenzi ngaphansi komthwalo we-axial wodwa. Kumele idlulisei-torque ephezulu yokushayelaku-rotor ye-downhole ngenkathi futhi iphethe isisindo sentambo emgodini womthombo. Ngenxa yalokho, uhlelo lwezinduku lungaphansi kokuhlanganisaukucindezeleka kwe-torsional, i-axial tension, ukulayisha nge-cyclic, futhi, emithonjeni echezukile, eyengeziweukuxhumana namashubhufuthigqoka. Kule sevisi, ibanga lenduku, ububanzi, isistimu yokuxhuma, nokukhetha kokuhlanganisayo kufanele kufundwe ndawonye.
• Phakathi kuukugqwala kahle, umbuzo wokuklama awukona nje kuphela ukuthi intambo ingathwala umthwalo. Kuphinde futhi ukuthi izinga lenduku ekhethiwe lingakwazi yini ukuligcinagijima impiloebukhoneni beamanzi akhiqiziwe, CO2, H2S, kanye nohlelo lwangempela lwe-inhibitor. Kule mithombo,-idizayini yeyunithi yezinhlamvu kufanele icabangele ingozi yokugqwala, ukusebenzisana kokukhathala, kanye nokuthi izinga elikhethiwe lihlala lifanelekile yini phakathi nesikhathi esigcwele sesevisi.

Izindukuzixhunywe nguukuhlangana, kanye nokukhethiweikilasi lokuhlanganisakuthinta kokubilirod-ubuqotho beyunithi yezinhlamvufuthiukugqoka amashubhu.
