Iimveliso
Isixhobo sokugaya iCandelo le-API 7-1 Casing
Iprofayili yemveliso
I-Section mill luhlobo lwesixhobo sokuvula iifestile zekhava esidibanisa imisebenzi yokusika iikhava kunye nokugaya. I-section mill ingena kwikhava kunye ne-BHA, kwaye isike i-casing kwindawo echaziweyo kuqala. Emva kokuba i-casing inqunyulwe ngokupheleleyo, iya kugaywa ngqo ukusuka kule ndawo. Emva kokufikelela kubunzulu obuthile, umsebenzi wokuvula iifestile zekhava ugqityiwe. I-section mill inezibonelelo zesakhiwo esilula, ukusebenza okulula ukuyenza ibe sisixhobo sokuvula iifestile zekhava esisebenzayo kakhulu.
Okwangoku, i-section mill ingacinezela ize ifake isamente xa isetyenziswa ekushiyeni imisele, nto leyo enokwenza isamente idibane ngqo nolwakhiwo kumgama omde ngaphakathi kwe-360 degrees. Isamente ingangena kwidama ngokwemibhobho ekhoyo kunye nokuqhekeka kolwakhiwo, kwaye isiphumo sokuvala singcono kakhulu kuneso sokucinezela isamente emva kokugqobhoza.
Umgaqo wokusebenza
Emva kokuba i-section mill ithotywe yaya kwindawo ekhethiweyo kwi-casing kunye ne-BHA, qala itafile ejikelezayo, uvule ipompo, i-piston kwisixhobo ityhalelwa ezantsi luxinzelelo, ikhowuni esezantsi yepiston ityhala ii-cutting blades zivuleke kwaye zilungise umngxuma ovulekileyo. Xa ii-cutting blades zivuleka ukuya kububanzi obuphezulu, ukulungiswa komngxuma ovulekileyo kugqityiwe. Phantsi koxinzelelo lwepompo oluqhubekayo, i-blade ingavulwa kwaye ilungiswe umngxuma ngokuthe ngqo. Emva kokuba ipompo imisiwe, i-piston iphinda isetyenziswe phantsi kwesenzo sentwasahlobo kwaye ii-cutting blades ziya kurhoxiswa ngokuzenzekelayo.

(5) Ubunzima bezinto ezikrwada buphezulu kwaye isakhiwo sifanelekile. Xa sisebenza, sisika isinyithi endaweni yokusila isinyithi.
2. Ukuhlolwa okungqongqo kwezinto zokwenza imveliso
I-tungsten carbide ekhethwe yinkampani yethu iya kuthunyelwa kwi-arhente yovavanyo lobuchwephesha ukuze ihlolwe emva kokuba ibhetshi nganye ifikile. Ukuqinisekisa ukuba ubunzima be-alloy kunye nezinye izalathisi ziyahlangabezana neemfuno zemveliso yenkampani.
3. Inkqubo yokuwelda egqibeleleyo
Siqesha owayesakuba ngumwelisi omkhulu kaBaker Hughes kwaye sikhetha izixhobo ezifanayo zokuwelda kunye nezixhobo ezincedisayo kwiworkshop kaBaker Hughes ukuze sivelise ubuchwepheshe bowelding bukaBecker kwiinkqubo nakwizixhobo.
Ukuze sinciphise ukuguquguquka kwezixhobo ngenxa yotshintsho lobushushu ngaphambi nasemva kokuwelda, siseka inkqubo yokugquma ukuwelda ukuqinisekisa uzinzo lwejiyometri yemveliso kunye nokusebenza kakuhle.
Inkqubo yokusebenza kwesixhobo sokugaya icandelo le-IV.
Ukulungiswa komngxuma:
1. Lungisa i-casing. Lungisa i-downhole casing nge-taper mill okanye i-casing shaper.
2. Ukucoca iMithombo. Hlamba ioyile eluhlaza okanye ezinye izinto eziphuma emthonjeni ngamanzi acocekileyo.
3. Ukukrwela ikheyiji okanye i-wellbore. Ukukrwela kunye nokukhuhla imibhobho kufuneka kwenziwe nge-scraper eqhelekileyo kunye nobubanzi bokukhuhla ukuya kwiimitha ezingama-20 ngaphantsi kwendawo yokusila yecandelo.
4. Lungisa ulwelo lokusila. Iimpawu zalo ezahlukeneyo zinokuqinisekisa ukuba luyakwazi ukuthwala inkunkuma ngendlela ezinzileyo.
Uvavanyo lomhlaba:
1. Vavanya ukuthembeka kwezixhobo;
2. Utshintsho loxinzelelo lwepompo luyavavanywa xa kuvulwa iiblade zokusika, nto leyo enika isiseko sokugweba ukuba isingxobo esingaphantsi komhlaba sinqunyulwe ngokupheleleyo na.
Ukukhetha indawo yokugaya:
1. Isamente engaphandle kwebhokisi yokusila yecandelo kufuneka ifakwe isamente kakuhle.
2. Kuphephe indawo apho i-casing ikhutshiwe kwaye iguquguquka khona. Ukuba kukho indawo enjalo, umsebenzi kufuneka wenziwe kwi-30-40m ngaphezulu kwendawo. Kwaye indawo yokuqala yokusebenza kokusika mayibe yi-1-3m ngaphezulu kwendawo ekufutshane.
3. Ipokotho mayigcinwe phantsi komngxuma. Ngokubanzi, ubude bepokotho bufanele bube ngaphezu kwe-100m.
Ukusika ikesi:
① Emva kokudibanisa isixhobo kwi-BHA uze uqhubele ezantsi kwindawo yokugaya icandelo, qala itafile ejikelezayo ukuze ubone indawo yokudibanisa ikheyisi ngokwerekhodi yekheyisi (ukuloba), uze wehlise isixhobo siye malunga ne-1-3m ngaphezu kwekheyisi kunye nebhuleki ekufutshane.
② Qala itafile ejikelezayo kuqala, yonyusa isantya sokujikeleza siye kwi-50-60r / min, qala ipompo, yonyusa kancinci kancinci ukufuduka, ukuze uxinzelelo lwepompo lunyuke. Ngeli xesha, uxinzelelo lwepompo luyanda ukusuka kuncinci ukuya kukhulu, lunyuka kancinci ukuya kwi-10-12mpa.
③ Qhubeka usika isingxobo imizuzu engama-20-45. Xa uxinzelelo lwepompo luhla ngequbuliso nge-2-5mpa, isingxobo siyanqunyulwa. Ukuze umzimba wesikhi uvulwe ngokupheleleyo, gcina indawo yokusika kule ndawo imizuzu engama-30 emva kokusika, kwaye wonyuse kancinci kancinci ukufuduka ukuqinisekisa ukwakheka okupheleleyo kokuqhekeka.
Ibhokisi yokusila:
I-WOB inokwandiswa kancinci kancinci emva kokuba i-casing inqunyulwe. Elawulwa phakathi kwe-10-25kn, isantya esijikelezayo siyandiswa siye kwi-80-120r / min, kwaye uxinzelelo lwepompo lulawulwa ngaphakathi kwe-10MPa ukuqinisekisa ukuba ukuhanjiswa okujikelezayo kunokuthwala inkunkuma yesinyithi. Xa icandelo ngalinye limalunga ne-0.5m, lingagrunjwa nge-1m ukuze kujikelezwe kwaye kujikelezwe, ukuze kube lula ukuba inkunkuma yesinyithi egayiweyo ukusuka kwicandelo ibuye kakuhle nge-annulus. Emva kwemijikelo yemijikelo eyi-1-2, gqobhoza kwakhona ukuze uqhubeke nokwenza kunye nokugaya.
[Kwinkqubo, kuyimfuneko ukulungisa ngokufanelekileyo ukusebenza kodaka ngelixa unyusa ukufuduka; kwangaxeshanye, hambisa ngokufanelekileyo isixhobo sokubhola kwaye ulungise ukujikeleza kwegazi ukuze wenze iitships zesinyithi zibuye ngokupheleleyo kwaye kuthintelwe ukuqokelelwa kobumdaka]
