I-MPD (uxinzelelo olulawulwayo lwe-drilling) Inkcazo ye-IADC yinkqubo yokomba eguquguqukayo esetyenziselwa ukulawula ngokuchanekileyo iprofayili yoxinzelelo lwe-annular kuwo wonke umthombo.Iinjongo kukuqinisekisa imida yoxinzelelo lwe-downhole kunye nokulawula iprofayili yoxinzelelo lwe-hydraulic annular ngokufanelekileyo.I-MPD yenzelwe ukuphepha ukungena ngokuqhubekayo kolwelo lokubumba ukuya kumphezulu.Nakuphi na ukuthontelana okunokwenzeka kumsebenzi uya kugcinwa ngokukhuselekileyo kusetyenziswa iinkqubo ezifanelekileyo.
Inkampani yethu njengomboneleli wenkonzo ofanelekileyo weMPD (i-Managed Pressure Drilling) itekhnoloji kwi-CNPC kunye ne-CNOOC, okoko kwasungulwa iinkonzo zetekhnoloji ze-Halliburton zeMPD e-China ngo-2010, siye saqokelela inani elipheleleyo le-25 yeenkonzo zobugcisa ze-MPD ze-CNPC kwixesha elidlulileyo le-13. iminyaka, kuquka 8 amaqula nobunzulu obudlula 8000 yeemitha.
Okwangoku, inkampani yethu ineqela lenkonzo yobugcisa yabasebenzi abangaphezu kwama-60, kuquka iinjineli ezili-17 ezineminyaka engaphezu kwe-10 yamava kwiinkonzo zeMPD kunye neenjineli ezingama-26 ezineminyaka engaphezu kwe-5 yamava e-MPD.Ime njengomnye wababoneleli benkonzo yobuchwephesha beMPD eTshayina.
