Bulu loyikidwa
Kupanga kwa ROP wapamwamba pobowola mawonekedwe ozama komanso ovuta, kubowoleza PDC nthawi zonse kumaboola kuchokera pansi mpaka pansi mwachindunji kapena kuthamanga kamodzi, kupulumutsa nthawi yayitali ndi mtengo.
Kusiyanitsa ndi tricone bit, PDC kubowola pang'ono kumayenda ndi WOB yotsika koma RPM Yapamwamba, chifukwa chake imagwira ntchito ndi mota yotsikira kuti ikwaniritse liwiro lozungulira.
Magwiridwe a PDC kubowola pang'ono zimadalira kwambiri pa odulira PDC, timapereka yankho lapadera pazofunikira pamitundu yosiyanasiyana.
Mpweya wa Daimondi Phula uli ndi tsamba la Cylindrical lomwe lili ndi ROP wokwera pamaulalo olimba komanso olimba olumikizana ndi pulasitiki.
Mawonekedwe
Zojambula Zojambula:Ili ndi kapangidwe kake kakuzindikira kwamphamvu komanso kapangidwe kake. Ndioyenera denser shale ndi argillaceous s ndi mwala, ndipo quartzs ndi mwala wokhala ndi abrasiveness yayikulu, miyala yamatope ndi miyala yamchenga yolumikizana ndi miyala ndiyabwino.
Kapangidwe kapangidwe kake kakang'ono: Masamu apadera ndi makonzedwe amkati mwa koboolera amakongoletsa magwiridwe antchito pakatikati pobowola kuti atalikitse moyo wonse wa kubowola.
Ukadaulo
Njira yapaderadera: Kapangidwe ka ufa wa matrix wokhala ndi ufulu wodziyimira payokha waluso komanso ukadaulo wapamwamba wopanga sintering wapangitsa kuti makina a matrix afike pamlingo wapadziko lonse lapansi.
Makina ambiri otaya: Njira yozungulira komanso yozama ikuyenda bwino pakutsuka ndi kuyendetsa cuttings ndikupewa kuponyera pang'ono.
Mawonekedwe
1. Makonda apakati amakona a kondomu: Chulu chamkati cha chidacho chimakhala ndi mawonekedwe ndi mawonekedwe apadera, omwe amalimbitsa magwiridwe antchito a gawo lapakati la phula ndikuwonjezera moyo wonsewo.
2.Kapangidwe kakang'ono komanso kozama kothamanga: Chozungulira chachikulu komanso chothamanga kwambiri, chomwe chimathandizanso kuyeretsa ndikusuntha kwa cuttings ndikupewa kubowola matope.
3. Khola lamkati losungidwa: Kutalika kwauzimu ndikutetezera kutalika kwa chipu chakuchotsa poyambira komanso kapangidwe ka mano odula omwe angathenso kulandidwa.
Ukadaulo
1. Matrix osakanikirana ndi zigawo za diamondi mwa mankhwala apadera kuti agwirizane ndi mapangidwe, kukhathamiritsa mdulidwe wa diamondi, mphamvu zomata ndi kuvala kukana kuti mupeze ROP wabwino.
2. Makina Osakanikirana Osakwanira
Kapangidwe kakang'ono konse kameneka kamakhala ndi kuwunika kwamphamvu kwamadzimadzi kowonetsetsa kuti kugaya ndikubwezeretsanso kachidutswa kamadulidwa kumachotsedwa.
Pang'ono pathu pathupi pathu pathunthu timatha kuboola mapangidwe kuchokera ofewa mpaka ovuta.
3.Mitengo imakhala ndi zigawo zopangidwa ndi zosakaniza zapadera za diamondi ufa wamitundu yosiyanasiyana ndi aloyi. Kuphatikizika kumatha kupangidwira kuboola munjira zosiyanasiyana.
Chida Chosindikizidwa Chinali ndi magwiridwe antchito apamwamba a Turbine Xiwang Oilfield
MAVUTO
Tinthu Tomwe Tili PDC ndi Tricone
Tinthu sitingathe kugwira bwino ntchito popanga zovuta kwambiri pomwe Limestone ndi Dolomites
CHINTHU
Kuti mukwaniritse bwino, kapangidwe kokhazikika kalimbitsa Impregnated Bit 8 1/2 ”DI705 kuyika chopangira turbine.
Zotsatira
Ndi zowerengera zowerengeka za 103. nthawi yonseyi ili pafupifupi maola 37. 5, ndipo ROP ndi 2.75.
Chidule
Mu Xiwang Oilfield ku China, mapangidwe ake ndi ovuta kwambiri omwe ndi miyala yamiyala / ma dolomite ndipo mphamvu ya compress ndi 24000PSI -32000PSI. Wogwiritsa ntchito amafunika kuboola dzenje la 8 1/2 ”ndi chopangira mphamvu. PDC Bit kapena Tricone Bit yabwinobwino sinayende bwino mgawoli. Kutengera izi, Deefast imapereka zotsimikizika za Impregnated Bit (8 1/2 ”DI705) kuti ipake chopangira mphamvu ndikukwaniritsa zolinga zabwino.

Magwiridwe
The Impregnated Bit (8 1/2 "D1705) ndichinthu chatsopano chomwe chimapangidwa kuti chikhale chosinthira makina opangira ndi kupanga molimba.
Ndi mawonekedwe apadera amakona amakono ndi kulimbitsa thupi la matrix, zakulitsa mphamvu ndi kukhazikika kwa pobowola mu lithology ya abrasive. Ndi zowerengera zowerengeka za 103, nthawi yonseyi ili pafupifupi maola 37.5, ndipo ROP ndi 2.75 mita / ola. Kasitomala amakhutira ndi magwiridwe ake ndikuthandizira kupulumutsa nthawi ya 30% komanso pafupifupi 50% mtengo poyerekeza ndi yankho lakale.
