Iinkonzo zePakethe
Ngokusekwe kwiprofayili yomthombo, idatha ye-geological stratification kunye nedatha ye-lithology, iimpawu zoyilo lweemotor zangaphantsi kunye neziphumo zesicelo sangaphambili, i-DeepFast iya kwenza uyilo lweemoto eziwela kulwakhiwo lwezixhobo zekhompyuter.
Ngaphezu koko, siqinisekisa ukuba zonke iimoto ezisezantsi ziyangqinelana nobuchwephesha obuchanekileyo kwaye zithunyelwa ngexesha ngokweemfuno. Inkampani yethu izimisele ukwenza oku kulandelayo:
Phambi kwentengiso:
1.Ukulawula ngokungqongqo umgangatho weemoto ezisezantsi ukuthintela i-NPT ngenxa yeengxaki zomgangatho.
2. Phambi kokuba kusombiwa, siya kulungisa iinjini ezihamba phantsi komhlaba size sizithumele kwindawo efanelekileyo yequla ngokwesicelo somsebenzisi.
3.Ngokweemfuno zobuchwephesha zokuhlolwa nokwamkelwa, ii-OD motor, uhlobo, isiqinisi kunye nomgangatho we-welding ziya kuhlolwa ngokungqongqo kwaye zamkelwe ngaphambi kokuthunyelwa.
Inani elaneleyo leemoto ezisezantsi ligcinwe kwiqela lokomba xa kunokwenzeka ukuba ixesha eliguqukileyo kunye neemeko zendlela.
Ngexesha lokuthengisa:
Ukuhanjiswa kwe-1 kubuchwephesha bokubonelela ngeenkonzo zobuchwephesha iiyure ezingama-24 abancedisa ukucebisa iiparameter zokomba ezifanelekileyo, ukuqokelela idatha yokusetyenziswa, ukunika ingxelo kwangexesha kumasebe ezobuchwephesha kwinkampani ekuphuculeni iinjini eziwela ezantsi kunye nokuthintela ukhetho olungalunganga lweemoto ezisezantsi ezikhokelela kwangoko ukusilela.
2. Emva kokugqitywa kokutyikitywa kwesiza, iimoto ezingasetyenziswanga neziphume emthonjeni ziya kukhunjuzwa.
Siza kwenza amanyathelo okulawula umngcipheko kwaye sazise abasebenzisi xa umxholo wenkqubo yoyilo kunye neskimu sobugcisa sitshintsha.
Emva kwentengiso:
Ukusombulula nokusombulula iingxaki ezivela ekusetyenzisweni kweemveliso kwangexesha.
Emva kokusetyenziswa kweemveliso zenkampani yethu, ukuba abasebenzisi banethemba lokuyilungisa, inkampani yethu iya kuyenza kuvavanyo lobuchwephesha lweemveliso emva kokuyisebenzisa kwaye inike ikowuteshini entsha ngokwezinto zokugcina kunye nezinto ezinokutshintsha. Ukongeza kutshintsho lwemilomo kunokuhanjiswa kwangexesha kunye nokutshintshwa kwesiza, ezinye izinto ezinje ngokusika kunye nentambo zonxibelelwano kufuneka zilungisiwe.
Uyilo olwahlukileyo kunye neeNkonzo:
1.Eipip kunye neengcali ezininzi zobugcisa, eziqhelekileyo ngesakhiwo se-geological, kunye neepropati ezinamanzi kwiindawo eziphambili zeoli
Iinkonzo 2.Offer elungelelanisiweyo
Khulisa ukusebenza kwemveliso kunye nesiqinisekiso sokungalahli into ngexesha elinye.
Iimpawu ezininzi ezihamba phambili
Iimoto ezisezantsi zonyusa i-torque ngama-50-100% xa kuthelekiswa nezinye iimveliso kunye nobude bokuphila bonyuka ngamaxesha angama-1-2
Iimveliso ze-4 ezipheleleyo
Sinikezela ngeentsimbi zeDayimani, iimoto eziwela ezantsi, izixhobo zokomba ngokukhawuleza, iibheringi ze-TC, iimveliso zoomatshini zerabha eziphezulu.
5. I-7700m kunye ne-Well Well
Iikhontrakthi zokomba zinzima kakhulu kwaye zinobunzima eSichuan Basin, kuMazantsi mpuma e China. Uninzi lwamaqula akulo mmandla ziimitha ezingama-6,000-7,000 ubunzulu.
I-Rotary Steerable PDC Bit kunye ne-Downhole Motor
zisetyenziswe ngempumelelo kwibhlokhi yerhasi yomnatha
IINGXAKI
Kwirhasi engathethekiyo ye-shale, umqhubi wokumba angathanda ukunciphisa ukugunyaziswa kweNkcitho (i-AFE) ngokususa iihambo ezineendleko kunye nezixhobo ezongezelelekileyo ezinxulunyaniswa neendlela ezininzi zokubaleka.
ISISOMBULULO
Ukuzila ngokukhawuleza kunika izixhobo zokudibanisa i-PDC Drill Bit kunye ne-Downhole Motor kwiNkqubo yeRotary Steerable System yokwandisa ukubhola kwesikhokelo ngesantya esiphezulu sokujikeleza, ukuzinza kunye nobomi benkonzo ende.
IZIPHUMO
Ngemifanekiso eqokelelweyo yeemitha ezili-1301. zeemitha ezingama-700 zagrunjwa ngokuthe tyaba
Ixesha lokusebenzisa iimoto ezantsi ziiyure ezingama-229 kwaye inqanaba lokungena li-11 leemitha ezili-12 ngeyure
Isuntswana elisetyenzisiweyo ligcina i-95% o njenge-bit entsha yoqobo
Ushwankathelo
Kutshanje, isantya se-PDC esine-rotary motor kunye ne-downhole motor ngokuzimeleyo ephuculwe yinkampani yethu ziye zatshatiswa ngempumelelo kunye nezixhobo ezijikelezayo zangaphandle ezijikelezayo kwithambeka lokuvula lesithathu kunye necandelo lequla elithe tyaba le-Wei202H2-10 (2936-4237m, ukubunjwa kweLongmaxi). Inkampani yeGreat Wall. Ifezekisile ukusebenza okulindelweyo kwaye ngamxhelo mnye banconywa ziinkampani zokomba kunye neenkampani zenkonzo yokuyalela.
Ukusebenza
Isuntswana le-PDC elitshatayo kunye ne-downhole motor yokugrumba phantsi kabini kwicandelo elonyukayo. ngemifanekiso eqokelelweyo yeemitha ezili-1301 apho iimitha ezingama-700 zagrunjwa ngokuthe tyaba. Ixesha lilonke lokomba ziiyure ezili-117. Ixesha elipheleleyo lokusetyenziswa kweemoto ezihamba ezantsi ziiyure ezingama-229, kwaye inqanaba lokungena eliphakathi li-11.12 yeemitha ngeyure. Njengomphumo wokutshintsha indlela yesiqhelo yokukhupha isuntsu ngelixa kusombiwa ulwalathiso, isuntswana elisetyenzisiweyo yi-95% njenge-bit entsha yentsusa.
Ushwankathelo
Kwi-2018. Ukuyilwa kubunzima obuphakathi kodwa bukrwada eSichuan yase China, i-DeepFast ibonelela ngenkonzo ehlangeneyo (izixhobo ezantsi zokuqeshisa iinkonzo) zomsebenzisi wokugqibela. Kwibhlokhi yeSichuan, kukho ezimbini ezifanayo ezifanayo ze-JY-66-1 HF kunye ne-JY-66-2 HF. Ukuzila ngokukhawuleza kunika izixhobo zokudibanisa ukudibanisa kunye neemoto ezihamba phantsi ukukhuphisana nenye inkampani enika kuphela i-drill bit okanye i-motor kuphela.
Umsebenzi wokuSebenza
| Kulungile Hayi. | Imifanekiso (m) | Iindleko zeDril Bits (RMB) | Ixabiso leZithuthi ezihamba ezantsi (RMB) | Ixesha lokomba | Umndilili weROP | |
| Enye inkampani (iibhithi ezisi-7 zokumba + iinjini ezi-4 ezantsi) | IJY-66-1HF | 1698 | 676000 | 385000 | Iintsuku ezingama-26 | 6.5 m / h |
| I-DeepFast (i-5 drill bits +4 i-downhole motors) | IJY-66-2HF | 1909 | 531900 | Iintsuku ezingama-22 | 8.67 m / h |
Iziphumo Thelekisa
Ngokunikezela ngokuphuculwa kweebhithi zokomba kunye neenjini eziwela ezantsi, i-DeepFast iphuhlisa izixhobo zokomba ngokudibanisa netekhnoloji yayo. Isuntswana le-PDC ekumgangatho ophakamileyo kunye nexesha elongezelelekileyo lobomi beemoto ezihamba phantsi ziyaphumelela ukukhuphisana nesinye isixhobo sokuqhuba kunye neemoto ezantsi.
Okona kubaluleke kakhulu, i-DeepFast ibonelela ngesixhobo sayo sokuyila kunye neemoto ezihamba ngokudibeneyo kwaye zisetyenziswe kakuhle. ezisebenza ngokukuko kunenkampani yabanye ezinikezela kuphela nge-drill bit okanye iimoto ezihamba ezantsi.
Ngaphaya koko, i-Deep Fast ibonelela ngeenjineli zokugrumba kwinkonzo yasentsimini kwindawo ekuncedeni ukusebenza. Ngenxa yokudityaniswa kwezi zixhobo, i-DeepFast inceda abathengi ukugcina iintsuku ezi-4 kunye ne-50% yeendleko zemali. Ngapha koko, iphucula i-33% ROP.
