Upangiri Wathunthu Wosankha ndi Kugwiritsa Ntchito Tricone Drill Bit

Pobowola mozungulira, thekubowola pang'onoimagwira ntchito ngati chida choyambirira chophwanyira miyala. Ubwino wa pobowola ndi kuphatikizika kwake ndi mtundu wa mapangidwe, mawonekedwe a thanthwe, ndi mikhalidwe yobowola imakhudzanso liwiro la kubowola. Kusankha mtundu wabiti woyenera ndikubowola potengera momwe mapangidwe ake amapangidwira ndikofunikira pakuwongolera bwino pakubowola ndikutsitsa mtengo. Kubowola kwakuya kumakumana ndi mitundu ingapo yamiyala yokhala ndi zinthu zosiyanasiyana, kupangakubowola pang'onokusankha ntchito yovuta.

1. Epirical Bit Selection Njira

Imadziwikanso kuti Field Drilling Data Method, iyi ndi njira yothandiza komanso yogwiritsidwa ntchito kwambiri pakati pa akatswiri akumunda. Imadalira kusanthula deta yochokera ku zitsime zapafupi m'dera lomwelo, kuyang'ana kwambiri mitundu yaying'ono yomwe idakwanitsa kujambula bwino kwambiri komanso kulowera kwapakati pamikhalidwe yofananira ndi yakuya. Njirayi ndi yosavuta, yothandiza, komanso yoyenera kumadera omwe ali ndi mapangidwe ofanana.

2. Njira Yosankha Bit Yotengera Zotengera

Kuti athe kuthana ndi malire a njira zoyeserera, njira iyi imaphatikizanso deta yodula mitengo mwamayimbidwe ngati chizindikiritso chosalunjika, kukulitsa kulondola kwasayansi. Imadziwika kuti "Reference Method," imafunikira ogulitsa pang'ono kuti afanizire magawo opangidwa kuchokera kumitengo yama coustic yokhala ndi ma tempulo osankhidwa okhazikika, ndikupangitsa malingaliro olondola.

3. Zofanana Zotheka Kusankha Pang'onoNjira

Njirayi ikutsatira njira yokhazikika:

• Pezani data yoyeserera poyesa kapena njira zolosera.
• Gwiritsani ntchito kusanthula kwazomwe zasonkhanitsidwa pakubowola miyala kuti mudziwe kuthekera kwapakati pa kubowola (Kd) ndi zolakwika zokhazikika (S) pamapangidwe aliwonse.
• Ndi tchati chosankha pang'ono khodi ya IADC, fananizani ndi luso la kubowola kuti muzindikire mitundu yoyenera pakupanga kulikonse.

4. Analimbikitsa Kubowola Parameters kwa Onse Formations

Kuchita bwino kwa akubowola pang'onozimadalira kusankha mtundu wa bitti yoyenera ndikugwiritsa ntchito zoboola zoyenera.

5. Drillability Profile ndi Bit Selection kwa Puguang Formation

Pogwiritsa ntchito chidziwitso cha geological ndi kudula mitengo kuchokera m'zitsime za ku Puguang, magwiridwe antchito adawunikidwa ndikugawidwa molingana ndi magawo a geological ndi kukula kwa boreholes kudzera mu "Drill Bit Technical Efficiency Index" (JX=VL=avereji yamakina olowera × pang'ono).

• Mapangidwe ndi Lithology Mbiri: Tsatanetsatane wa mayina osanjikiza, makulidwe, ndi mitundu ya miyala yomwe idakumana nayo mdera la Puguang.
• Drillability Profile ndi Kusankhidwa Kwa Bit Kovomerezeka: Kumayika mapangidwe ndi ma IADC ma code kutengera milingo yobowola.
• Malingaliro a Epirical Bit Selection: Kutengera ndi data yogwiritsiridwa ntchito kwa zigawo, izi zimapereka masinthidwe ang'onoang'ono ovomerezeka amitundu yofanana.
• Malangizo a Engineering Parameter: Kuwerengera kulemera kwapang'onopang'ono (WOB), RPM, hydraulic power index, ndi poyambira WOB kutengera kukumba miyala.

6. Malangizo pa Kusankha Bwino Kwambiri Kubowola ndi Kugwiritsa Ntchito

(a) Kusankha Motengera luso la Lithology ndi Kubowola: Kusankha kobowola kuyenera kuyang'ananso kapangidwe ka luso lobowola, ndikusintha motengera mbiri yaubongo yomwe amakumana nayo pakubowola.

(b) Mfundo Zazikulu zaZithunzi za PDC: Nthawi zambiri,Zithunzi za PDCndizoyenera kupanga zofewa mpaka zapakati.

• Kwa mapangidwe ofewa okhala ndi pulasitiki wapamwamba, gwiritsani ntchito ma bits okhala ndi mainchesi akuluPDCocheka ndi mawonekedwe a highcutter kuti apititse patsogolo kuswa miyala.
• Pamapangidwe apakati-olimba okhala ndi pulasitiki yotsika, sankhani tizidutswa tating'ono tating'onoting'ono ta PDC ndi mawonekedwe otsika kuti mupewe kusweka kwa odula ndikukulitsa moyo wa zida.

(c) Kupititsa patsogolo Kubowola Parameters Kutengera Mapangidwe Ang'onoang'ono ndi Mapangidwe Apangidwe: Konzani magawo-monga WOB, RPM, ndi mphamvu ya hydraulic-kutengera kapangidwe kake ndi mapangidwe ake, ndikuwonetsetsa kuti akukhalabe m'magulu ovomerezeka.

(d). Kusankha Njira Mwa Kuzama Kwa Chitsime ndi Kapangidwe:

• Pamapangidwe akuya, phatikizani ma PDC okhala ndi ma motors otsika kuti muwonjezere kuthekera kwakukulu kwa RPM.
• Pakuzama kwapakati, zokhala ndi mainchesi akulu, onjezani WOB ndikuchepetsa RPM ngati koyenera kuti mukwaniritse bwino pobowola.
