Zomwe Zimakhudza Ubwino Wobowola ndi Kuthamanga

1. Popeza kuthamanga kwa kubowola kwapawiri kuwirikiza kawiri kwa zida II za pobowola, ndipo pafupifupi kanayi kuposa gear I, ndikosavuta kukulitsa kwambiri ROP.

2.Kuthamanga kwapamwamba kwapawiri kubowola ndi koyenera kwa makhalidwe odula a PDC bit mu kupanga kukameta ubweya.

3.Wellbore trajectory ndi yosalala. Kuphatikiza kubowola kolowera ndi kubowola kotsetsereka kuti musinthe kwakanthawi, ndikosavuta kuwongolera mbali ya dogleg ndikuwonetsetsa chitetezo chapansi.

4.Chida chobowola chimapangidwa bwino. Pobowola pawiri, kuthamanga kwa kubowola kumakhala <100-120kN, ndipo zofunika pakubowola zimatha kumalizidwa ndi makola obowola ochepa kapena opanda, ndipo mwayi womamatira umachepetsedwa kwambiri.

5. Kubowola kwapamwamba kwa PDC kumagwirizana ndi chida chobowola mphamvu pobowola zitsime, zomwe zimapewa kulephera koyambirira kwa cone kunyamula pa liwiro lalikulu ndipo sizimayambitsa ngozi zotayika.

Kukokera kwa Ma Parameters Kubowola pa Kubowoleza Kuthamanga Kwambiri

Pa kubowola ndondomeko, chikoka cha pobowola magawo pakati zinthu controllable pa liwiro pobowola sangathe kunyalanyazidwa, monga: pang'ono mtundu, pang'ono nozzle awiri, pang'ono madzi mphamvu, pang'ono kuthamanga, liwiro, mpope kuthamanga, kusamutsidwa, etc. Pankhani ya zolinga zina, ROP nthawi zambiri imachulukitsidwa poyang'anira kuthamanga kwa kubowola, kuthamanga kozungulira, kuthamanga kwa pampu ndi kusamuka.

Mphamvu ya Kubowola Madzi pa Kubowola Ubwino ndi Kuthamanga

Kubowola madzimadzi ndi magazi pobowola, choncho ntchito pobowola madzimadzi n'kofunika kwambiri pobowola. Zinthu zazikulu zomwe zimakhudza ROP ndi kukhuthala kwamadzi obowola, kuchuluka kwa madzi obowola komanso kulimba kwamadzi obowola. Poona kuti mankhwala omwe amagwiritsidwa ntchito m'chitsime chakuya chamadzimadzi omwe alipo ali ndi ma chromium ions ndi ayoni ena olemera kwambiri omwe amakhudza kwambiri chilengedwe, tikulimbikitsidwa kuti tiphunzire ndikugwiritsa ntchito madzi obowola bwino zachilengedwe. dongosolo kukonza silicate pobowola madzimadzi dongosolo panopa ntchito ang'onoang'ono osiyanasiyana ku China , Synthetic mfundo pobowola dongosolo kupanga zakuya bwino chilengedwe pobowola madzimadzi mndandanda oyenera geological ndi umisiri zinthu m'dera lililonse pobowola.
