Izinto Ezichaphazela Umgangatho Nesantya Sokugrumba

1. Ekubeni isantya se-drill bit sokugrumba okudityanisiweyo siphindwe kabini kune-gear II ye-drilling rig, kwaye phantse siphindwe kane kune-gear I, kulula ukuyinyusa kakhulu i-ROP.

2. Isantya esiphezulu sokujikeleza sokugrumba okudityanisiweyo sifanelekile kwiimpawu zokusika ze-PDC bit xa kusenziwa i-shear.

3. Indlela yokuqhuba iWellbore igudile. Ukudibanisa ukubhola kwicala elithile kunye nokubhola okutyibilikayo ukuze kutshintshwe isithuba, kulula ukulawula i-engile ye-dogleg kunye nokuqinisekisa ukhuseleko lomngxuma ongaphantsi.

4. Ulwakhiwo lwesixhobo sokugrumba lwenziwa lula ngempumelelo. Ngexesha lokugrumba okudityanisiweyo, uxinzelelo lokugrumba ngokubanzi lungaphantsi kwe-100-120kN, kwaye iimfuno zokugrumba zinokugqitywa ngeekhola zokugrumba ezimbalwa okanye zingabikho kwaphela, kwaye amathuba okunamathela ancitshiswa kakhulu.

5. I-PDC drill bit esebenza kakuhle isebenzisane nesixhobo sokugrumba ngamandla ukugrumba imithombo, nto leyo ethintela ukusilela kwangethuba kwe-cone bearing ngesantya esiphezulu kwaye ayibangeli iingozi zokulahleka kwe-cone.

Impembelelo yeeParamitha zokuDrila kwisantya soMgangatho wokuDrila

Ngexesha lenkqubo yokugrumba, impembelelo yeeparamitha zokugrumba phakathi kwezinto ezilawulekayo kwisantya sokugrumba ayinakutyeshelwa, ezinje: uhlobo lwebhithi, ububanzi be-nozzle yebhithi, amandla amanzi ebhithi, uxinzelelo lwebhithi, isantya, uxinzelelo lwepompo, ukufuduka, njl. Kwimeko yeemeko ezithile ezijolise kuyo, i-ROP idla ngokwandiswa ngokulawula uxinzelelo lokugrumba, isantya sokujikeleza, uxinzelelo lwepompo kunye nokufuduka.

Impembelelo yolwelo lokubhola kuMgangatho kunye nesantya sokubhola

Ulwelo lokugrumba ligazi lokugrumba, ngoko ke ukusebenza kolwelo lokugrumba kubaluleke kakhulu ekugrumbeni. Izinto eziphambili ezichaphazela i-ROP kukuxinana kolwelo lokugrumba, ubuninzi bolwelo lokugrumba kunye nomxholo oqinileyo kulwelo lokugrumba. Ngenxa yokuba iarhente yonyango esetyenziswa kwinkqubo yolwelo olusezantsi ekhoyo ityebile kwii-ion ze-chromium kunye nezinye ii-ion zesinyithi esinzima ezinempembelelo enkulu kwindalo esingqongileyo, kuyacetyiswa ukuba kufundwe kwaye kusetyenziswe inkqubo yolwelo lokugrumba olujulile olunobuhlobo nokusingqongileyo ukuphucula inkqubo yolwelo lokugrumba olusilicate olusetyenziswa ngoku kuluhlu oluncinci eTshayina. Inkqubo yokwemba esisiseko yokwenziwa ukwenza uthotho lolwelo lokugrumba olukhuselekileyo nokusingqongileyo olufanelekileyo kwiimeko zejoloji kunye nobunjineli bendawo nganye yokugrumba.
