Kana chitubu chekugadzira kana kumhanya kwematanda kuchipisa tembiricha yakanyanya, high pressure, corrosive fluids kana kudzokororwa mechanical stress, kusarudza tambo kunova basa-rakakosha. Gwaro iri rinoongorora magadzirirwo etambo epamusoro, anotsanangura kuti ndezvipi zvekushandisa uye bvunzo zvine basa, uye inopa cheki chekutenga chinobatika kuitira kuti zvikwata zvekutenga zvisarudze tambo dzinoderedza nguva yekudzikira, kudzivirira zvemagetsi uye yakaderera mutengo wevaridzi (TCO). Shandisa izvi paunenge uchitsanangura matende, kuongororaJSH tambovatengesi vanonyanya kukanganisa kuzere kumashure.
Ndedzipi mhando dzetambo dzepasi dzakagadzirirwa matsime akaoma?
Tambo dzepazasi dzinowira mumhuri shoma dzakanyatsozivikanwa: tubing-encapsulated magetsi conductor (TEC), faibha-optic downhole tambo (tube-mu-tube TEF magadzirirwo), simbi-tambo dzemagetsi jeketi uye specialized high-temperature fluoropoly{6}in. TEF/fiber magadzirirwo akajairika kune fiber telemetry uye kugoverwa kunzwa; simbi-mabhachi uye masitaera eTEC anoshandiswa panodiwa dziviriro yemuchina uye kusamira nesimba. Sarudza mhuri nekuti unoda telemetry, simba, kana hybrid (simba + data).
Ndezvipi zvinhu uye zvivakwa zvinopona kupisa kwakanyanya, makemikari uye kudzvanywa? (sainzi pfupi)
Zvinhu zvakakosha uye zvivakwa zvinosimbirira pa:
Fluoropolymer uye engineered fluoropolymers (PTFE, FEP, PFA, specialized fluoropolymers):yakanakisa makemikari kuramba, yakaderera hydrolysis uye yakagadzikana dielectric kuita patembiricha yakakwirira; inoshandiswa mu premium downhole insulated waya.
Mabhachi esimbi / chubhu-mu-chubhu (simbi/aluminum):kupa kupwanya kuramba, axial simba uye kumanikidza kutendeseka (zvakajairwa muTEF uye TEC magadzirirwo).
Yepamusoro-zvekuvharisa uye mafirita (SiO₂, -maceramic ekupisa / mapolymer akakosha):inoshandiswa apo tembiricha inodarika yakajairwa polymer miganhu; SiO₂ zvivakwa zvinoshandiswa munzvimbo dzine hutsinye.
Nhengo dzezvombo uye simba (galvanized steel, Stainless):dzivirirai kubva pakupwanya uye kurema panguva yekumhanya-mukati.
Ndeipi tembiricha uye kudzvanywa ratings yandinofanira kuda mune specs?
Rondedzera zvidiki zvakaperera zvichienderana nemamiriro emutsime pamwe nechengetedzo margin. Yakajairika kutengeserana ratings iwe yauchaona uye inofanirwa kudikanwa mune zvinyorwa zvinyoro:
Standard downhole cables:rated ~kusvika150 degreekune akawanda mafuta & gasi downhole application.
Yepamusoro-tembiricha TEC / madhizaini akasiyana:rated to200 degree(uye dzimwe mhinduro dze bespoke dzinoti dzakakwirira). Kana tsime rako riine mafambiro ekupisa ari pamusoro pe150 dhigirii, inoda kuti vatengesi vatumire yakasimbiswa bvunzo data pane yakanangana tembiricha.
Zvekumanikidza/kupwanya: kumbira mugadziri kumanikidzwa / kupwanya data rekuyedza, pamwe nezvinyorwa zvekuputika/kupwanya zviyero (kana kudzvanywa-yakaenzana axial load curves) uye mu-kusimbisa tsime kana bvunzo mishumo.
Ndeapi zviyero uye bvunzo dzinoratidza kuti tambo ichararama mutsime? (chii chokukumbira)
Inoda izvi zvinhu zvekufanirwa mumabhidhi ekutengesa:
Manufacturer test reportkune yakakwira tembiricha soak, thermal cycling, hydrolysis/chemical exposure, uye pressure/crush.
Material certificates(insulation compound batch data, metallurgy).
Kukurumidza kuyedza hupenyuuye zvidzidzo zvemumunda / mareferensi kubva kumatsime ekudzika kwakaenzaniswa, tembiricha uye kemisitiri yemvura.
bvunzo{{0}dzebato rechitatu kana{1}mumbaye dielectric performance mushure mekuchembera kwekupisa (uye kune fiber tambo, optical attenuation mushure mekunyorova). Bvunza vatengesi vebvunzo maprotocol uye maitiro ekugamuchira anoshandiswa.
Ndivanaani vanovimbika vatengesi uye chii chinovasiyanisa? (mepu yevatengesi inokurumidza)
Mahombe, akasarudzika tambo maOEM ane akapupurirwa downhole chigadzirwa mitsara uye yepasirese sevhisi huwandu ndiyo yakajairika sarudzo yakachengeteka yematsime akakosha. Mienzaniso yevatengesi uye masimba ekufunga nezvawo:
Prysmian Group- -yakanyorwa zvakanaka pasi pehole/fiber TEF nemitsara yeTEC, tsigiro yeinjiniya yepasi rose uye yakadhinda zvinyorwa zveTEF zvemhando yepamusoro-yekushandisa. Yakanakira mapurojekiti makuru uye panodiwa tekinoroji traceability.
AFL / nyanzvi fiber suppliers- maassemblies akadzikama emaziso/fiber ane madhizaini anozivikanwa epamusoro- e tembiricha.
GORE (specialized insulated waya)- fluoropolymer wire inyanzvi yekunyanyisa makemikari/kupisa kwekudzivirira; kazhinji inoshandiswa kune yakakosha tambo wiring.
Nyanzvi tambo dzimba (Rochester Cable, GeoPSI, Meggitt, Weatherford tech zvinopihwa)- inopa magadzirirwo ezvivakwa, metallurgy uye maprofid field hardware kuitira kushandiswa kwakanyanya.
