API 152 hli PDC concave pob zeb ntsis 4 Hniav rau qhov dej drilling

Cov ntawv thov:
PDC concave laum ntsis yog ib hom laum me me puv ntoob, uas feem ntau yog siv rau hauv cov thee mine, kev khawb av, kev tshawb nrhiav geological, kev txuag dej thiab hydropower, txoj kev loj, kev tsheb ciav hlau, choj thiab kev tsim kho.
Lub laum no yog thawj qhov kev xaiv uas yuav tsum tau siv rau hauv kev khawb cov qauv nyuaj nrog kev ruaj khov zoo meej, kev ntws dej zoo thiab kev nkag mus sai.
• Hom:Hom ib txwm muaj; Hom muaj zog; Hom muaj zog heev.
• Cov xov:Txhua tus poj niam los yog txiv neej cov xov.

PDC sawv cev rau Polycrystalline Diamond Compact uas yog hais txog cov cutters ntawm cov laum no.

Cov ntsis PDC muaj cov nqi nkag mus zoo heev thaum drilling thiab tuaj yeem ua tau zoo dua lwm cov ntsis hauv cov xwm txheej zoo.

Cov txiav pob zeb diamond muaj zog dua li hlau 10 npaug tab sis lawv yog Brittle thiab tuaj yeem puas tsuaj rau hauv cov qauv tsis sib xws.

Cov khoom siv PDC nyiam tho qhov los ntawm cov pob zeb shale, cov pob zeb av nplaum ntsev, cov pob zeb ua vaj tse thiab cov xuab zeb. Tsis txhob siv cov xuab zeb thiab cov pob zeb xuab zeb.

PDC Bits yog ib qho kev xaiv zoo heev rau cov qhov dej kim lossis tob heev thiab tshwj xeeb tshaj yog thaum drilling hauv cov mos mos rau nruab nrab nyuaj formations.

Cov khoom me me PDC tuaj yeem tsim los ntawm cov hlau lossis cov khoom siv matrix.

Koj yuav tau txais lub qhov tob dua ntawm Matrix Body tab sis lawv tsis tuaj yeem kho lossis rov qab kho dua lawv yuav tawg yog tias lub tshuab driller cuam tshuam rau lub ntsis.

Lub ntsis PDC uas muaj lub cev hlau ruaj khov dua li lub cev matrix thiab yuav tsis tawg. Nws yuav tsis tho qhov tob heev tab sis nws tuaj yeem kho thiab rov qab tau.

Thaum siv ProDrill PDC bits los tho qhov, nws yog ib qho tseem ceeb kom paub thiab peb cov lus qhia txog qhov hnyav uas pom zoo rau ntawm lub pob zeb tho qhov thiab tswj qhov ceev ntawm kev tig.

Cov cuab yeej drilling tuaj yeem muab cov khoom PDC hauv qhov ntau thiab tsawg los ntawm 3.5 "(88.9mm) txog 12 1/4" (311.2 mm). Peb cov khoom PDC muaj 3 txog 6 tis, Jet Nozzles thiab kev tiv thaiv gauge.

kuj tsim cov khoom PDC rau RC drilling (rov qab ncig drilling) daim ntawv thov.
