1.Ukudonsa kwepayipi
Izinyathelo zokuvimbela ukwehluleka ukudonsa kabusha:
(1) Yenza ukuhlolwa okubonakalayo kwawo wonke amathuluzi okumba ngaphambiukumba okuqondayo okuqondileSebenza, futhi wenze ukuhlolwa kokuthola iphutha (y-ray noma i-x-ray (njll
. Ngokushesha, isikhathi sokuqina sethuluzi lokumba emgodini wendiza kufanele sifinyeze ngangokunokwenzeka, futhi akufanele ngedlule amahora angu-4. Uma kwenzeka kugxila, udaka luzofakwa emgodini ngezikhathi ezithile ukuze kugcinwe uketshezi lodaka emgodini.
(3) Ngaphambi kokuthi ipayipi lidonswe emuva, i-rigring rig, ithuluzi lokumba, uhlelo lokuxhaswa ngodaka neminye imishini izohlolwa futhi igcinwe (ngokulungiswa kwamarekhodi anamathiselwe) ukuqiniseka futhi uhlelo lwayo lwamandla nohlelo lwayo lusebenza kahle futhi lusebenza ngokujwayelekile. Flush umbhobho we-drill ngodaka ngaphambi kokubuyela emuva ukuze uqinisekise ukuthi ayikho into yakwamanye amazwe endaweni yokushayela; Uhlelo lwe-MUD lubushelelezi futhi ingcindezi ingahlangabezana nezidingo zokudonsa emuva. Ngesikhathi sokudonsa emuva, yenza isifutho sokuhlola ukuze uqinisekise ukuthi i-nozzle yamanzi ayivinjwanga. Ngesikhathi sokudonsela phansi, faka udaka olufanele ngokusho kwamapharamitha okumba, wehlise ukungqubuzana phakathi kwepayipi elidonsa kanye ne-hole wall rock, unciphise ukufudumala kwamapayipi, futhi uqinisekise impumelelo yokudonsa emuva.
Izinyathelo zokuqinisekisa ukuthi i-pipeline anti-corlosion coation ayilimali lapho umgodi unwetshwa futhi wadonswa emuva
. Lapho uhudula emuva, ububanzi be-reamer esetshenzisiwe bukhulu izikhathi ezi-1.5 bukhulu kunepayipi lokuwela ukunciphisa ukumelana nokudonsa phakathi kwepayipi nodonga lomgodi.
(2) Faka ukugeza umgodi ukuze uhlanze ukusikeka okwengeziwe emgodini futhi unciphise ukungqubuzana kwepayipi emgodini.
(3) Izilinganiso ze-MUD ziguquka ngezimo zezwe. Udaka luphathwa ngesikhathi sokudonsela emuva, futhi inani elithile le-lubricant lengezwa ukunciphisa ukumelana phakathi kwepayipi kanye nodonga lomgodi. I-viscosity yodaka kufanele ilungiswe nganoma yisiphi isikhathi ngokuya ngesimo sangempela. Ngokusho kwezinguquko zezwe, i-pud ratio viscosity kanye nengcindezi ziyalungiswa nganoma yisiphi isikhathi, futhi isilinganiso se-MUD sisetshenziselwa ukumisa okwesikhashana ipayipi odakeni ngesikhathi sokudonswa kabusha ukuze kuncishiswe ukuxabana.
(4) Ngemuva kokuthi u-Rinding uqediwe, qala uhlole ipayipi elingemuva. Ngemuva kokuqinisekisa ukuthi ungqimba lwe-anti-corriosion aluqinile futhi akukho ukuphazamiseka kwezenhlalo, ngokuya ngezimo zesayithi, ipayipi limisiwe ngokumba izimbumbulu zepayipi. .
. Ungqimba, nokulungisa umonakalo ngesikhathi lapho ukuklwebheka nokuvuza kutholakala, ukuze kugwenywe ukungena emgodini.
2.Indlela yokulingana, ukululama kanye
tIzindlela zokuphamba zodaka
Ukulungiselela udaka:
Isilinganiso sodaka sidlala indima enqumayo empumelelweni yokuwela. Ukuvunyelwa kokulungiswa kwe-pud yephrojekthi kuzosuselwa kwimidwebo ye-design kanye nedatha yokuthola indawo yezwe, ngokusho kokwabiwa kwe-vidcu ye-strata ehlukile ye-strata ehlukile, kufanele kuqinisekiswe ama-bhelo emfundo, ukusebenza kwe-lubricucation; Ngesikhathi sokuvuselela, ukuhlakanipha kodaka kuzolungiswa okungcono ngokuya ngerekhodi eliqondisayo ukuze kuqinisekiswe ukuthi udaka lunokusika okuqinile okuphethe umthamo kanye nokuvikelwa odongeni. Ngasikhathi sinye, esigabeni ngasinye sokuqondisa, ukwakhiwa kokwakha, ngokwemininingwane yangempela, engeza i-ejenti yokuqinisa udonga, ukuthuthukisa ukuwohloka kodonga, ukuthuthukisa izinga lephrojekthi, ukuqinisekisa ikhwalithi yephrojekthi eqediwe kahle. Izinto zodaka ikakhulukazi ze-Bentonite (zinobungani bemvelo), kanye nokucushwa kodaka kuncike ezimeni zenhlabathi ezibhekene lapho kudonsa khona ukumba. Kule phrojekthi ngokusebenzisa ukwakheka okuyinhloko, ukulungiselela udaka kwenkomba enkulu.
Ukululama nokwelashwa kwe-mud:
Ukuze ulawule ngempumelelo inani lodaka, vikela imvelo yemvelo, ngangokunokwenzeka ukuze usebenzise udaka olunobungane bemvelo, ukuvumelanisa kabusha, umkhawulo omkhulu wokunciphisa ukungcoliswa kwemfucumfucu, ngasikhathi sinye ukwelashwa kwemvelo, izindlela eziqondile zimi ngokulandelayo:
. Ngemuva kokuhlanzwa kokuqala, udaka lugeleza echibini lodaka ukuze lime. Ukuze usheshise imvula yezinhlayiya, i-axaffle isethwe echibini lodaka ukuze ushintshe iphethini yokugeleza futhi uchithe isakhiwo odakeni, ukuze kube lula ukwenziwa kwemvula kokusika kokumba.
. Kuyaqoqwa bese kudonswa ngeTank Truck kuya emgodini wodaka esizeni sokwakha.
.
3. Izindlela ezikhethekile zobuchwepheshe
I-Drilling Rig Anchloring System:
Enqubweni yokushayela okuqondayo, ngenxa yokungabi navimbelani kwesakhiwo sokwakha esingaphansi komhlaba, ukumba i-rig kuthinteka kakhulu ngamandla okuphendula wepayipi elidonsa emgodini ngesikhathi sokubuyela emuva. Ukwanda okungazelelwe kwengxabano kungadala ukungazinzi kwe-rig yokumba futhi ngisho nengozi yokugaya i-rig icofa ngaphezulu. Ngakho-ke, ukuqina kohlelo lwe-anchcoring lwe-rig yokumba kubaluleke kakhulu. Ngokusho kokuhlangenwe nakho kwale phrojekthi kanye nokwakhiwa kwangaphambilini, uhlelo lwe-anchloring lwe-rig yokumba selithuthukisiwe, ngokukhethekile ngokulandelayo:
(1) Beka i-anchor yomhlaba emgodini, futhi umugqa ophakathi kwebhokisi le-anchor ibhokisi elihambisana ne-axis yokuwela. Ingaphezulu le-Ground Anchor Box lifuhla umhlaba wemvelo, kanye nokucaciswa kokumbiwa kwebhokisi le-anchor lingu-6M × 2M × 2M.
. Ngemuva kokuthi i-anchor yomsila ixhunyiwe, umhlaba uyabuyiselwa emuva, futhi inhlabathi ezungeze ihange icindezelwa ngomshini nangokwezehlakalo. Khulisa umthamo wenhlabathi.
.
(4) Faka ipayipi lensimbi engu-6 × 0.8m ekugcineni kwesigxobo ukuze ukhuphule indawo yokucindezela yonke indawo futhi wehlise ingcindezi.
(5) Ngemuva kokufakwa, ipuleti lensimbi kufanele libekwe ohlelweni lwe-anchrong, futhi i-rig kufanele ipakwe ngenhla kwepuleti lensimbi.
Inkampani yezobuchwepheshe ye-gookma technology limitedibhizinisi le-hi-tech kanye nomenzi oholayo weumshini wokumba oqonde eqondileeChina.
