Ukugrumba ibhulorho yesanti ibambekile kwaye unyango lwengozi

Ukuxinga kwebhulorho yesanti ikwabizwa ngokuba yintlabathi ebambekayo, indalo yayo iyafana nokudilika, kwaye ingozi yayo imbi ngakumbi kunokuncamathela.

1.Isizathu sokwenziwa kwebhulorho yesanti

(1) Kulula ukwenzeka xa kusogwa ngamanzi acocekileyo ngendlela ethambileyo;
(2)I-surface casing incinci kakhulu, kwaye i-stratum ethambileyo ibonakala kakhulu;
(3) Ukongeza i-flocculant egqithisileyo kulwelo lokomba;
(4)isantya sokomba oomatshini siyakhawuleza, ukugrumba ulwelo lokufuduswa alukwazi ukuqhubeka;
(5)Tshintsha inkqubo yolwelo lokuqala lokomba equleni, okanye utshintshe kakhulu ukusebenza kolwelo lokomba;

Ibhulorho yesanti yokuncamathela into

(1) Akukho lulwelo lokomba lubuyiselwa kwintloko yomthombo ngexesha lokomba okanye ulwelo lokomba lubuyiselwa umva kwi-tumba umbhobho;

(2) Ukuxhathisa kwezixhobo zokomba kukuxhathisa okuthambileyo, kwaye akukho ukuxhathisa okusisigxina pi-oint;

(3) Ukuba ibhulorho yesantie kwenzeka ngexesha lokugaya, inqanaba le-annulus liquid liyancipha, kwaye inqanaba le-liquid kumgodi wamanzi wesixhobo sokugaya lihla ngokukhawuleza;

(4) Emva kokuba isixhobo sokugaya singene kwibhulorho yesanti, ngaphambi kokuba ipompo iqaliswe, ukunyuka nokuhla kwentshukumo kunye nokujikeleza kukhululekile.Ukuba impompo iya kuqaliswa, uxinzelelo lwempompo luya kukhwelase, ubunzima obumisiweyo buya kuhla, kwaye i-drilling fluid ayiyi kubuya okanye ibuye incinci kakhulu kwi-wellhead;

(5) Ekubhobhozeni, okufana nokuchithwa kolwelo oluncinci okanye isanti ephetheyo, kwinkqubo yokujikeleza kwempompo, isixhobo sokubhoboza phezulu kunye nokuhla kwentshukumo yokujikeleza akukho kumelana, xa umpompo umisiwe, isixhobo sokugaya asinakuphakanyiswa, ngakumbi akukho lulwelo oluqinileyo lwesigaba sokomba, oku kwenzeka ngakumbi.

Ukuthintelwa kwebhulorho yesanti exingayo

(1) Kungcono ukuba ungombi ngamanzi;

(2)Kwicandelo lomngxuma ovulekileyo, ixesha lokuphumla kolwelo akufuneki libe lide kakhulu;

(3) Ukuphuculwa kwe-druyilo lolwelo olugulayo;

(4) Xa kusetyenzwag, ubungakanani obufanelekileyo bompompo kufuneka bukhethwe ngokweempawu zokubunjwa;

(5) Ukugcina uzinzo lwenkqubo ye-drilling fluid kunye nokusebenza.

Unyango lwebhulorho yesanti ebambekileyo

(1) Ukuba i-drilling fli-uid inokungena kuphela kwimpompo, isixhobo sokugaya sibambekile, kwaye asikwazi ukushukunyiswa, kufuneka sibalwe indawo yekhadi lekhadi, kwaye ixesha kufuneka liguqulwe ukusuka kufuphi nendawo yekhadi.

(2) Indawo yokubunjwa kwebhulorho yesanti ingaba kwindawo ephezulu okanye engezantsi, kodwa icandelo layo lomthombo alide kakhulu, kwaye akunakwenzeka ukungcwaba zonke izixhobo zokugaya.Ukuba ibhulorho yentlabathi ikwindawo ephezulu, nangona kungekho zixhobo ezininzi zokugaya ezigalelwe okokuqala, akunakwenzeka ukuba kusetyenziswe umkhono omde we-barrel ukuguba ukususa ibhulorho yesanti, kwaye ke isixhobo sokubhola sikwiqhosha ukubuyisela ukujikeleza, kwaye kamvaizinto kulula ukuzenza.Ukuba ibhulorho yesanti ikwindawo esezantsi, indlela yokuqhushumba i-backbuckle ekhululekileyo kufuneka isetyenziswe ukugalela isixhobo sokugrumba esingafakwanga ngexesha, kwaye esi sixhobo silandelayo se-drill sinokukhutshwa kuphela nge-milling backbuckle.

3iately kwiqhosha, isixhobo sokomba, kunokwenzeka ukukhulula ikhadi kumsebenzi.Ukuba siyakwazi nokujikeleza ulwelo lokomba, zonke iingxaki ziya kusonjululwa.

(4) Ukuba umtya wokubhola uxhotyiswe nge-centralizer, ibhulorho yesanti isoloko ingaphezulu kwe-centralizer yokugqibela, ngoko emva kokuba i-casing mill ukuya kwi-centralizer, akukho mfuneko yokubuyisela ukugaya i-centralizer, kwaye ingqayi inokuxutywa kwaye engabambekanga.
