1.Pipe pullback
Njira zopewera kulephera kwa pullback:
(1) Yendetsani kuyang'ana zida zonse zobowola musanagwire ntchito, ndikuyang'ana zolakwika (kuwunika kwa Y-ray kapena X-ray, etc.) pazida zazikulu zobowola monga mapaipi obowola, ma reamers, ndi mabokosi osamutsa kuti muwonetsetse kuti pali palibe ming'alu ndipo mphamvu imakwaniritsa zofunikira zomanga.
(2) M'mimba mwake yomaliza ya chitoliro ndi chachikulu kuposa nthawi 1.5 za chitoliro chokokera kumbuyo. Kulumikizana kwa payipi pullback: mutu wa mphamvu - mutu woteteza mawere - chitoliro chobowola - remer - cholumikizira chozungulira - mphete yooneka ngati U - mutu wa thirakitala - Mzere waukulu, womwe ungathe kuonetsetsa kuti mphamvu zambiri za kubowola zimagwiritsidwa ntchito pa mphamvu yokoka panthawi ya pullback ndikuwonetsetsa kupambana kwa pullback.Poyimitsa kubowola, chida chobowola chiyenera kugwirizanitsidwa mwamsanga, ndi nthawi yopuma ya pobowola. chida mu dzenje woyendetsa ayenera kufupikitsidwa mmene ndingathere, ndipo sayenera upambana 4 hours.Mucikozyanyo, matope alakonzya kubikkwa mucibeela camusyobo ooyu kwaciindi cili mbocibede kubikkilizya abube bwamusyobo ooyo.
(3) payipi isanabwezedwe, chobowolera, chida chobowolera, chothandizira matope ndi zida zina ziyenera kuyang'aniridwa ndikusamalidwa bwino (ndi zolemba zosungira ndi kukonza) kuti zitsimikizire kuti chobowola ndi mphamvu zake zikuyenda bwino. ndikugwira ntchito bwino.Tsukani chitoliro chobowola ndi matope musanakoke kumbuyo kuti muwonetsetse kuti palibe chinthu chachilendo mu chitoliro chobowola;Dongo lamatope ndilosalala ndipo kupanikizika kungathe kukwaniritsa zofunikira za pullback.Panthawi ya pullback, yesetsani kutsitsi kuti muwonetsetse kuti mphuno yamadzi yatsekedwa.Pokoka, bayani matope oyenerera malinga ndi mmene kubowola, chepetsani kukangana pakati pa chitoliro chobowola ndi thanthwe la khoma la dzenje, onjezerani mafuta a mapaipi, kuchepetsa kutentha kwa chitoliro chobowola, ndi kuonetsetsa kuti chibowocho chikuyenda bwino.
Njira zowonetsetsa kuti zokutira zotsutsana ndi dzimbiri siziwonongeka dzenje likakulitsidwa ndikubwezeredwa.
(1) Pobowola dzenje loyendetsa ndege, gwirani ntchito yomangayo molingana ndi zofunikira za mapangidwe kuti muwonetsetse kuti dzenje loyendetsa ndege ndi losalala komanso lathyathyathya, ndipo pewani ngodya zambiri.Mukakokera m'mbuyo, m'mimba mwake wa reamer wogwiritsidwa ntchito ndi wokulirapo kuposa 1.5 kuposa m'mimba mwake wa chitoliro chowoloka kuti muchepetse kukana kukokera ndikuchepetsa kukwapula pakati pa chitoliro ndi khoma la dzenje.
(2) Onjezani pochapa mabowo kuti muchotse zodula zambiri mu dzenje ndikuchepetsa kugundana kwa payipi mu dzenje.
(3) Chiŵerengero cha matope chimasintha malinga ndi mmene zinthu zilili.Matope amathandizidwa panthawi ya kukoka, ndipo mafuta ochulukirapo amawonjezeredwa kuti achepetse kukana kwapaipi pakati pa payipi ndi khoma la dzenje.Kukhuthala kwamatope kuyenera kusinthidwa nthawi iliyonse malinga ndi momwe zilili.Malinga ndi kusintha kwa geological, kukhuthala kwa matope ndi kupanikizika kumasinthidwa nthawi iliyonse, ndipo chiŵerengero cha matope chimagwiritsidwa ntchito kuyimitsa payipi mumatope panthawi yopuma kuti achepetse kukangana.
(4) Kukonzanso kukamalizidwa, choyamba yang'anani payipi yokokera kumbuyo.Pambuyo potsimikizira kuti anti-corrosion layer ili bwino ndipo palibe kusokoneza kwa chikhalidwe cha anthu, malinga ndi momwe malowa alili, payipi imayimitsidwa pofukula maenje otumizira ndi milu ya dothi kuti ateteze anti-corrosion wosanjikiza wa payipi..
(5) Pamene payipi ibwezeredwa mmbuyo, ikani malo oti muzindikire kuti payipi ya anti-corrosion layer mita 30 isanalowe mubowo (kapena molingana ndi momwe zilili pamalowo), ndi kukonza antchito apadera kuti ayeretse pamwamba pa anti- corrosion layer pamaso pa malo ozindikira, kuti zikhale zosavuta kwa ogwira ntchito pamalo ozindikira kuti agwiritse ntchito EDM kuti adziwe ngati pali zipsera kapena zowonongeka pa anti-corrosion wosanjikiza, ndikukonza zowonongeka pakapita nthawi pamene zokopa ndi zotuluka zimapezeka. , kuti apewe kulowa m'dzenje.
2.Njira yofananira, kuchira ndi
tzoyezera matope
Kukonzekera kwa dothi:
Chiŵerengero cha matope chimakhala ndi gawo lalikulu pakuchita bwino kwa kuwoloka.The mamasukidwe akayendedwe a matope kasinthidwe ntchito adzakhala zochokera kamangidwe zojambula ndi deta geological ziyembekezo, malinga ndi Kugawilidwa kwanthaka osiyana matope mamasukidwe akayendedwe osiyana strata, m`kati pobowola mabowo kalozera, ayenera kuonetsetsa katundu wabwino rheological, kondomu ntchito;Pa reming, ndi matope mamasukidwe akayendedwe adzakhala kusinthidwa makamaka malinga ndi mbiri kutsogolera kuonetsetsa kuti matope ali amphamvu cuttings kunyamula mphamvu ndi chitetezo khoma.Pa nthawi yomweyo, mu gawo lililonse la kutsogolera, reaming ndi backtowing zomangamanga, malinga ndi deta yeniyeni, kuwonjezera khoma kulimbitsa wothandizira, viscosifier, lubricant, Chip kuyeretsa wothandizila ndi wothandiza wothandizila, kuonjezera matope mamasukidwe akayendedwe ndi simenti, kuonjezera bata la dzenje, kuteteza dzenje khoma kugwa, slurry kutayikira ndi zochitika zina, kuonetsetsa ubwino wa polojekiti anamaliza bwino.The matope zakuthupi makamaka bentonite (chilengedwe ochezeka), ndi matope kasinthidwe zimadalira zinthu nthaka anakumana pobowola.Pakuti polojekiti kudzera waukulu mapangidwe, matope kukonzekera waukulu index.
Kubwezeretsa ndi kuchiza matope:
Kuti bwino kulamulira kuchuluka kwa matope, kuteteza chilengedwe chilengedwe, mmene ndingathere ntchito zachilengedwe wochezeka matope, yobwezeretsanso, malire pazipita kuchepetsa m'badwo wa zinyalala matope, pa nthawi yomweyo kuteteza slurry kuipitsa, yake yobwezeretsanso kunja. chithandizo chachilengedwe, miyeso yeniyeni ndi iyi:
(1) Atsogolere matope ochezeka ndi chilengedwe omwe abwerera kuchokera pansi kupita kumayendedwe ozungulira, ndipo kudzera mumtsinje wozungulira ndi thanki yamatope, zodula zobowola zidzayendetsedwa kuti zitheke kuyeretsa.Pambuyo pa kuyeretsedwa koyamba, matope amathamangira mu dziwe lamatope kuti ayime.Pofuna kufulumizitsa mpweya wa particles, baffle amayikidwa mu dziwe lamatope kuti asinthe mawonekedwe otaya ndi kuwononga dongosolo mumatope, kuti atsogolere mpweya wobowola cuttings.
(2) Konzani antchito apadera kuti ayang'ane mzere, kulimbikitsa masomphenya oyendera, ndipo ngati pali slurry leakage point, konzekerani ogwira ntchito kuti amange cofferdam pamalo omwe slurry akutuluka kuti akhale ndi kuyeretsa mwamsanga, monga kuletsa matope kuti asasefukire komanso kukula kwa slurry kusafalikire.Amasonkhanitsidwa kenako amakokedwa ndi galimoto ya tanki kupita ku dzenje lamatope lomwe lili pamalo omangapo.
(3) Ntchito yomangayo ikatha, matope a m’dzenje lamatope pamalo omangapo amasiyanitsidwa ndi matope ndi madzi, ndipo matope otsalawo amawatengera kunja kuti atetezere chilengedwe.
3. Miyezo yapadera yaukadaulo
Drilling Rig Anchoring System:
Pobowola molunjika, chifukwa cha kusakhazikika kwa mapangidwe apansi panthaka, chobowolacho chimakhudzidwa kwambiri ndi mphamvu ya chitoliro chobowola mu dzenje panthawi yokonzanso ndi kubwezeretsanso.Kuwonjezeka kwadzidzidzi kwa mikangano kungayambitse kusakhazikika kwa choboolera komanso ngozi ya chobowola chodutsa.Chifukwa chake, kukhazikika kwa dongosolo lokhazikika la chobowola ndikofunikira kwambiri.Malinga ndi zomwe zinachitikira pulojekitiyi komanso zomangamanga zam'mbuyomu, njira yolumikizira makina obowola yasinthidwa, makamaka motere:
(1) Ikani nangula wapansi mu dzenje, ndipo mzere wapakati wa bokosi la nangula pansi umagwirizana ndi njira yodutsa.Pamwamba pa bokosi la nangula pansi ndi lonyowa ndi nthaka yachilengedwe, ndipo mafotokozedwe ofukula a bokosi la nangula ndi 6m×2m×2m.
(2) Nangula ya mchira wa tubular imayikidwa mamita 6 kumbuyo kwa bokosi la nangula pansi, ndipo bokosi la nangula pansi ndi nangula wa mchira zimagwirizanitsidwa ndi ndodo zogwirizanitsa.Pambuyo pa nangula wa mchira, dziko lapansi limabwereranso kumbuyo, ndipo nthaka yozungulira nangula imakanizidwa mwamakina komanso mwachinyengo.Wonjezerani mphamvu yobereka nthaka.
(3) Ikani mlongoti wautali wa mamita 6 kumbali zonse za bokosi la nangula kuti thupi lalikulu lisapendekeke.
(4) Ikani chitoliro chachitsulo cha 6 × 0.8m kumapeto kwa mtengo kuti muwonjezere malo opanikizika kulikonse ndikuchepetsa kupanikizika.
(5) Pambuyo poikapo, mbale yachitsulo iyenera kuikidwa muzitsulo zoyimitsa, ndipo chotchingacho chiyenera kuyimitsidwa pamwamba pa mbale yachitsulo.
