Ukukhetha umboneleli wentambo ofanelekileyo kwizicelo ze-downhole sisigqibo esiphezulu-sempembelelo esichaphazela ngokuthe ngqo ukuthembeka kwenkqubo, ukhuseleko, kunye neendleko zizonke zobunini. Iintambo zomgobo ophantsi zisebenza kwiimeko ezinzima kakhulu-ubushushu obuphezulu, uxinzelelo oluphezulu, kunye nemekobume enobunkunkqele bekhemikhali{3}}apho nemiba yobulunga emincinci inokukhokelela kwixabiso eliphantsi okanye ungenelelo olungcono. Esi sikhokelo sicacisa indlela amaqela okuthenga kunye nobunjineli anokuvavanya ngayo ababoneleli esebenzisa ubuchule obucacileyo, urhwebo, kunye neendlela zokuthobela ukuqinisekisa{5}}ukusebenza kwexesha elide kunye nokunciphisa umngcipheko wokusebenza.
Yintoni kanye kanye "iintambo zomhobo" - kwaye kutheni ukhetho lomthengisi lubalulekile?
Iintambo ze-Downhole (izixhobo, amandla, i-fiber okanye i-hybrid designs) zakhiwe ukuze ziphile kumaqondo obushushu aphezulu, uxinzelelo oluphezulu lwe-hydrostatic, iikhemikhali ezinobundlobongela, ukukrazula kunye nobomi obude benkonzo. Ukusilela kubiza amashumi okanye amakhulu amawaka kumsebenzi, imveliso elahlekileyo, kunye nomngcipheko wokhuseleko - ngoko ke amava omboneleli, ukhetho lwemathiriyeli kunye novavanyo olubhaliweyo lubalulekile{2}}. Iinkokeli zeshishini (abavelisi beentambo ezikhethekileyo kunye neenkampani zenkonzo ye-oyile esekiweyo) ziyila imingxunya echongiweyo eyaziwayo kwaye zineembali zeemeko zamaqula afanayo.
Yeyiphi imigangatho kunye neziqinisekiso ekufuneka umthengisi wakho azithobele?
Funa ubungqina bokuthotyelwa kwemigangatho yoshishino olusebenzayo kunye nezenzo ezicetyiswayo ezifana neenkcukacha ze-API zamacandelo ombane angaphantsi komhlaba, i-API ecetyiswayo yezenzo zovavanyo lwentambo ye-ESP, kunye nemigangatho ye-ISO esebenzayo esetyenziswa kwi-petroleum/geothermal applications. Iikopi okanye amanani ereferensi yeengxelo zovavanyo kunye nomgangatho womthengisi{1}izatifikethi zenkqubo (umzekelo, ISO 9001, kunye nayo nayiphi na i-NDT/uxinzelelo{5}}iirekhodi zovavanyo) kufuneka zinikwe ngaphambili. Sebenzisa la maxwebhu ukuthelekisa iiapile{7}}kunye{8}}neeapile phakathi kwabathengisi.
Yeyiphi imiba yokusingqongileyo kunye nombane ebaluleke kakhulu (ubushushu, uxinzelelo, amandla ombane, ukuthomalalisa)?
Amanqaku aphambili bubushushu obuphezulu bokusebenza, ukukala koxinzelelo lwe-hydrostatic (kunye nawaphi na ukuwa/amanani agqabhukileyo oyilo olugqunyiweyo), ukuhambelana neekhemikhali (ukumelana nekrwada, i-brines, i-H2S, i-CO₂), i-voltage kunye ne-ampacity (kubandakanywa nokulinganisa ukuhla kwamandla ombane phezu kobunzulu bequla), kunye nokunciphisa idatha ye-fiber/instrumentation cores. Kwimithombo egqithisileyo ye-geothermal okanye ye-EGS,{2}}iintambo zobushushu obuphezulu ezibekwe ngaphezu kwe-150℃zingafuneka; Uyilo oluthile lweHT lukhona ukuya kuthi ga kwi ~232℃kunye nophando lovavanyo luphonononga 250–320℃degree. Tshatisa usapho lwemveliso yomthengisi neyona mvulophu yakho imbi{8}} kwaye ufune ubungqina bovavanyo.
Izinto zokwakha kunye nolwakhiwo - loluphi ukhetho loyilo oluchaphazela ubomi obude?
Ukhetho loyilo olubalulekileyo lubandakanya i-metallurgy ye-conductor kunye ne-stranding (ukumelana nokudinwa), ukugquma okuphambili (EPR, XLPE, abicah, PTFE variants for temp high), layering (isikrweqe, amalungu adityanisiweyo okuqina, okanye ukuyila kwetyhubhu/TEC), iibhatyi zangaphandle (i-chem/abrasion resistant polymers okanye iityhubhu zetsimbi ze-encapsulation), nokuba (intambo ejikelezileyo ithande ukungqukuva) eziphezulu{{0}zoxinzelelo/ezinzulu izicelo). Umbhobho-kwi-kwityhubhu okanye kwityhubhu{4}}uyilo lwefayibha egqunyiweyo kunye nejacket ekhethekileyo (ye-H₂S kunye neehydrocarbons) zisetyenziswa ngababoneleli abanamava.
Intambo ye-JSH, i-AFL kunye nezinye iingcaphephe zomngxunya onjalo zibonelela ngolwakhiwo olunjalo - thelekisa i-database kwaye ucele{1}}imizobo yecandelo kunye nespekthi zemathiriyeli.
Abaxhasi kufuneka bavavanye njani - kwaye kobuphi ubungqina bovavanyo ekufuneka unyanzelise kubo?
Uvavanyo olubalulekileyo lubandakanya ukuqhubeka kunye nokumelana nokugquma, uvavanyo oluphezulu -lokusenokwenzeka (ihipot), ukukhutshwa okungaphelelanga -kumoya we-voltage cores, umqhubi we-DC onganyangekiyo, uxinzelelo kunye novavanyo lokudilika (kwizoyilo ezigqunyiweyo), ubushushu{2}}ukuguga, ukomelela/ukwandiswa kunye nokuguquguquka{3}}kunye novavanyo lokudinwa kokusingqongileyo/ukudinwa. I-API RP 11S6 (uvavanyo lwentambo ye-ESP) kunye namaphepha ovavanyo lwefektri yomthengisi yindawo yokuqala yokuqala; Gxininisa kuthotho{7}}izatifikethi zovavanyo ezinamanani ezinokulandelelwa kubude bentambo nganye. Iimvavanyo zokwamkelwa kwentsimi (ezibonwayo, i-megger, ukuxhathisa kwe-DC, kunye noxinzelelo / ukuhlolwa kokucwiliswa) kufuneka kube yinxalenye yokuhanjiswa kunye nokugunyaziswa.
Imiba yorhwebo - amaxesha okukhokela, i-MOQ, izinto ezisetyenzisiweyo, kunye nexabiso lilonke lobunini
Qwalasela ixesha lokukhokela (ixesha elide-uyilo lomngxunya oqhelekileyo oluqhelekileyo), ubuncinci bomyalelo (MOQs), nokuba umthengisi ubambe{1}}impahla egqityiweyo, ukupakishwa kwenqanawa yohambo lwaselwandle/uhambo olude, kunye nokubakho kobude obungasetyenziswayo okanye izixhobo zokulungisa. I-Factor kwimiqathango yewaranti, imigaqo-nkqubo yokubuyiswa / yokulungisa, kunye nokukwazi umthengisi ukuhambisa izinto ezingxamisekileyo okanye ukulungiswa kwendawo. Ixabiso lilonke lobunini (TCO) kufuneka liquke ixabiso lexesha lokuphumla-nge{5}}ukusilela, ulungiselelo kunye nogcino, kunye nezithuba zokubuyisela ubomi bomjikelo - hayi nje ixabiso lokuqala. Ababoneleli abanee-ofisi zasekuhlaleni okanye -amaqela enkonzo anciphisa ixesha lokuphendula kwaye bahlala bezisa ubomi obungcono{9}}kuqoqosho lomjikelo.
Uvandlakanywa njani ubuchule bomthengisi kunye nenkxaso
Khangela: izixhobo zobunjineli ezabelwe iprojekthi yakho; izifundo ezibhaliweyo kwiimeko ezifanayo (ubushushu, ubunzulu, ikhemistri); kwi-uqeqesho lofakelo lwesiza; isitokhwe sasekuhlaleni okanye{1}}amaqabane enkonzo; kunye nobungqina be-R&D eqhubekayo (umz., iinkqubo zentambo zeHT). Cela ukufikelela kuphicotho-zincwadi lwasefektri okanye{5}}iingxelo zophicotho lweqela lesithathu kwaye ucele iireferensi zabaxumi onokuthi ubafowunele. Ababoneleli ababonelela ngobunjineli besicelo (ubalo lokuhla kwamandla ombane, umzila wentambo kunye nesikhokelo sokugoba kwiradiyasi,{7}}ekugunyazisweni kwesiza) banciphisa iimpazamo zofakelo.
