Impregnated Core Bit
Tsim kom muaj ROP siab dua hauv kev sib sib zog nqus thiab sib zog ua haujlwm, PDC xyaum me ntsis ib txwm xyaum los ntawm hauv av mus rau hauv qab ncaj qha nrog tsawg lossis txawm tias ib zaug khiav, txuag ntau qhov kev siv sijhawm thiab tus nqi.
Sib txawv los ntawm tricone ntsis, PDC laum me ntsis khiav nrog WOB qis dua tab sis siab dua RPM, yog li nws feem ntau ua haujlwm nrog lub tshuab qis qis kom tuaj yeem nrawm nrawm.
Kev ua tau zoo ntawm PDC laum me ntsis nyob ntawm ntau ntawm PDC cov tshuab txiav, peb muab cov kev daws teeb meem tshwj xeeb rau qhov xav tau tshwj xeeb ntawm cov ntawv sib txawv.
Drilling nyob rau hauv cov txheej txheem nyuaj Nws yog qhov tsim nyog rau kev sib tsoo hauv cov txheej txheem nyuaj heev, xws li cov xuab zeb.

Tshuab
◆ Tus kheej-sharpening impregnated ntxig
Qhov ua kom pom tseeb tus kheej ntxig rau ntxig rau ua kom txiav ntse thaum drilling.
◆ Cov cim matrix tshwj xeeb
Cov qauv sib txawv matrix ua rau matrix sib phim hnav thiab tsim, ua kom zoo dua txiav
Taw qhia:
Nws yog qhov tsim nyog rau coring hauv cov txheej txheem nyuaj heev, xws li xuab zeb.
Nta
1.Kev khoov crown: Cov yas nkhaus muaj cov tub ntxhais du

Impregnated Core Bit Complete Core Service
Hauv Kev Tsim Nyuaj Tshaj Plaws thiab Sib Sib Zog
HNUB NYOOG
Nyuaj heev thiab txhuam tsim
Qhov tob yog li 4,000 meters
Thov kom tus nqi rov zoo
DAWS
Txhawm rau daws cov teeb meem no, DeepFast muab Impregnated Core Bit 8 1/2 "x 4" DIC280 kom ua tiav lub hom phiaj no hauv kev sib sib zog nqus thiab nyuaj.
XAUS
Nrog cov tub ntxhais txiav 1 15 meters hauv ob qhov kev sib tw. uas yog los ntawm 3805 txog 3920 meters
Lub sijhawm kho yog kwv yees li 20 teev, thiab ROPIS 5.75 m/h
Tus nqi rov qab yog ntau dua 85%
Txheej txheem cej luam
Hauv Liaohe Oilfield hauv Suav teb, tus neeg ua haujlwm Liaohe Oilfield Coring Technology Services tau npaj los ua qhov dej tob tob ntawm 3805 meters. Kev tsim yog ib qho nyuaj heev thiab lithology yog granite nrog lub zog sib zog ntau dua 24000PSL. Nws lub hom phiaj yog ua lub hauv paus 8 1/2 "ntu ntu ntawm lub qhov dej kom rov ua tau cov tawv tawv. Qhov PDC cov tub ntxhais ib txwm muaj tsuas yog tus nqi rov zoo thiab txo cov tub ntxhais txiav. Yog li Deepfast muab nws qhov tshiab tsim Impregnated Core Bit kom ua tiav lub hom phiaj no hauv kev sib sib zog nqus thiab nyuaj.

Cov txiaj ntsig
Tus neeg teb xov tooj qhuas qhov haujlwm no yog txoj haujlwm zoo heev. Qhov Impregnated Core Bit 8 1/2 "x 4" DIC280 ua tiav 115 meters cov tub ntxhais txiav tsuas yog ob txoj hauv kev tob ntawm 3805 txog 3920 meters. Tag nrho lub sijhawm tseem ceeb tsuas yog 20 teev uas txuag ob txoj haujlwm thiab 24 teev uas txhais tau tias txuag 128,000 RMB. Ntxiv mus, qhov nruab nrab ROP yog 5.75 m/h thiab tus nqi rov zoo yog ntau dua 85, uas tseem dhau qhov kev cia siab. Cov yuam sij kom ua tiav qhov kev ua tau zoo no yog qhov tsim me ntsis thiab txhim kho kom nws tuaj yeem ntsib qhov nyuaj thiab txhuam cov ntawv. DeepFast tsis tsuas yog txhim kho lub zog ntawm cov cuab yeej sib dhos tau npaj rau ntau hom pob zeb, nws tseem tau kho qhov ntxig tsis tau ntxig thiab nkhaus crown tsim kom nce ob qho rov qab thiab ROP.
