Talu ai nei, o le Roteri steerable PDC laʻititi ma downhole afi tutoʻatasi atinaʻeina e la matou kamupani ua maeʻa lelei faʻatasia ma le faʻaulu mai o loʻo faʻataʻavaleina faʻafoe mea faigaluega i le vaega lona tolu o le avanoa ma le faʻavaega vaieli vaega Wei202H2-10 (2936-4237m, Longmaxi faʻavae) viliina e le 'au 50022 o Great Wall Drilling Company. Ua ausia le faamoemoe faamoemoeina ma maua autasi viia e viliina kamupani ma faatonuga kamupani tautua.

O le rotary steerable PDC bit and downhole motor viliina i lalo faalua i le vavave faʻateleina vaega, ma le aofaʻi o ata o 1,301 mita, lea 700 mita na viliina faʻasolosolo. O le aofaʻiga o taimi e vili ai le 117 itula, o le aofaʻi o sikulima faʻaaoga taimi e 229 itula, ma o le averesi o le sao i totonu o le 11.12 mita i le itula. O se faʻaiuga o le suia o metotia masani o le toso mai i fafo ao faʻagaoioiga viliina, o le faʻaaogaina laititi o 95% o le muaʻi fou laʻititi.

 

O le Roteri uli uli PDC o se fou fou ituaiga o laʻitiiti faʻapitoa atiaeina e la matou kamupani mo fetuʻutuʻunaina le Roteri steerable meafaigaluega ma rotary faʻafouina downhole afi e faʻafetaui ai manaʻoga o shale kasa atinae ma faʻatulagaina faapitoa. Lenei ituaiga o laʻititi tuʻufaʻatasia ma la tatou tutoʻatasi atamai meatotino aia tatau o le faʻatonutonu faigofie-ia-faʻatonutonu tekonolosi, puipuia le faʻaaogaina o tekinolosi, Faʻaleleia atili tekonolosi ma vaʻaia maualuga-faatinoga PDC Cutters. E i ai uiga o le lelei azimuth pulea, maualuga rotary saosaoa, leai se pa'ū, fale o manu faʻagaioiga ma umi auaunaga ola ao viliina.

 

O le alualu i luma manuia ma le faʻaogaina o le rotary steerable PDC laʻititi ma downhole afi o se tasi tele aoga a le tatou kamupani i le tutoʻatasi suʻesuʻega ma atinaʻeina o mea viliina meafaigaluega. O lona faʻalauiloaina ma le faʻaaogaina e mafai ona suia ai oloa faʻaulufale mai, matua faʻaititia le viliina o tau, ma lona maketi vaʻaiga lautele.
