Txheej txheem cej luam ntawm pob zeb diamond tho cov cuab yeej

Pob zeb diamond laum cov khoom siv tau siv rau kev tshawb nrhiav, thiab rho tawm hauv genology, metallurgy, catroleum, thiab tsim cov tshuab hluav taws xob, thiab tsim cov tshuab tsim khoom. Piv nrog tsoos hlau thiab tawv alloy laum cov khoom muaj cov txiaj ntsig zoo xws li kev siv hluav taws xob siab, cov khoom siv lub teeb tseem ceeb, kev sib tsoo yooj yim.

 

Cov ntaub ntawv ntxov tshaj plaws ntawm kev siv pob zeb diamond raws li lub tshuab ntim rau pob zeb drilling hnub rov qab mus rau 1751, thaum ntuj lub pob zeb diamond tau hais tias ua kom lub raj drilling zoo ib yam li lub laum me ntsis; Nyob ib ncig ntawm 1860, thawj lub pob zeb diamond drilling Rig tau tsim, loj hlob heev kev siv tshuab ntawm kev ua haujlwm. Tom qab ntawd lub pob zeb diamond laum me ntsis thiab cov tshuab tau txais txiaj ntsig tau txais kev lees paub thiab muaj qee lub tebchaws tsim tau xws li Tebchaws Asmeskas; Nyob ib ncig ntawm 1945, cov tib neeg tau pib kawm txog kev siv hmoov metallurgy los tsim cov pob zeb diamond laum cov khoom thiab ua tiav tiav. Nyob rau tib lub sijhawm, cov tshuab drilling ceev, thiab txij thaum ntawd los, Pob Zeb Diamond, tshwj xeeb tshaj yog siv tau siv hauv kev khiav tawm. Qhov tshwm sim ntawm cov hluavtaws hluavtaws hluavtaws hauv xyoo 1950 txuas ntxiv txhawb cov kev loj hlob ntawm tho cov khoom; Raws li cov txheeb cais tsis tiav, 60-80% ntawm tag nrho cov teb chaws tsim tau los ntawm pob zeb diamond laum khoom. Txij li xyoo 1960 txog xyoo 1967, Pob zeb diamond Low Bits account rau 20-30}% ntawm kev siv lub ntsej muag drilled qeeb hauv Tebchaws Meskas. Xyoo 1975, lub tshuab drilling ntawm geological pob zeb cores tau txog txog 5.5 lab meters; Tag nrho drilling qhov tob ntawm pob zeb diamond laum cov siv siv los ntawm lub qub Soviet Union hauv xyoo 1967 yog li 26 xyoo, thiab txog 4.8 lab meters xyoo 1970.

 

Thaum xyoo 1970, pob zeb diamond polycrrystalline thiab composite disc (PDC) laum khoom tau tsim. Xyoo 1973, Asmeskas Christensen cov tuam txhab uas koom tes nrog GE tuam txhab los tsim cov khoom lag luam PDC, uas tau hloov pauv dav hauv roj av, gEological kev tshawb nrhiav, lossis kev lim dej. Lub npe nrov geoset laum me ntsis yog ib qho nyuaj matrix tho kev ua los ntawm hmoov metallurgy siv cov muaju voos lossis polygonal diamond Lub Stratapax Laum cov menyuam roj av polycrystall lossis composite sib xyaw hauv lub taub lim dej hauv lub pob zeb nrog txoj kev txiav sib tshuam rau kev coj ua. Nws yog qhov tsim nyog rau drilling mos thiab nruab nrab tawv pob zeb, nrog drilling efficienty ntawm {2} cm / min thiab ib tho lub neej ntawm ntau dua 4000 meters. Lub sydrill series laum cov nplais ntawm de nphua yog ib qho zoo sib xws rau txoj kev stratapax.

 

 

Kev tshawb fawb thiab kev thov ntawm pob zeb diamond laum khoom hauv Suav teb tau pib lig (nyob rau hauv nruab nrab -1960 s), tab sis tsim kom sai. Xyoo 1970, lawv tau siv dav hauv kev lag luam xws li metallurgy, geology, centfield, thiab roj av. Tshwj xeeb tshaj yog nyob rau hauv cov roj av secor, kev tshawb fawb, thiab kev siv ntawm pob zeb diamond laum me ntsis tau hais txog lub sijhawm ntev, thiab tau ua tiav cov txiaj ntsig zoo. Piv txwv li, xyoo 1972, Shengli Oilfield siv hluav taws xob hluavtaws polycrerstalline (tsuas yog tsim nyog rau kev siv softer siab tshaj plaws nrog kev ua kom drilling ib qho zoo nrog ib laum me ntsis. Raws li cov txheeb cais tsis tiav, Shengli Oilfield tau qhia txog 3500 PDC Laum
