MPD (inotungamirwa kudhiraivha) IADC tsananguro ishanduko yekuchera inoshandiswa kunyatso kudzora iyo annular pressure profile mukati metsime.Zvinangwa ndezvekuona iyo downhole pressure nharaunda miganho uye kubata annular hydraulic pressure profile zvinoenderana.MPD inoitirwa kudzivirira kuenderera kwemvura yekugadzira pamusoro.Chero kuwanda kunoitika pakuvhiya kuchachengetwa zvakachengeteka uchishandisa maitiro akakodzera.
Kambani yedu seanopa masevhisi ane hunyanzvi weMPD (Managed Pressure Drilling) tekinoroji kuCNPC neCNOOC, kubvira pakaunzwa Halliburton's MPD tekinoroji masevhisi kuChina muna 2010, takaunganidza huwandu hwemakumi maviri neshanu akamisikidzwa eMPD tekinoroji masevhisi eCNPC mumakore gumi nematatu apfuura. makore, kusanganisira 8 matsime ane kudzika kunodarika 8000 metres.
Parizvino, kambani yedu ine tekinoroji sevhisi timu yevanopfuura makumi matanhatu evashandi, kusanganisira gumi nemanomwe mainjiniya ane anopfuura 10 makore echiitiko muMPD masevhisi uye makumi maviri nematanhatu mainjiniya ane anopfuura makore mashanu eMPD ruzivo.Inomira seimwe yeakanyanya simba MPD tekinoroji sevhisi vanopa muChina.
