Cov Lus Qhia Txog Cov Lus Qhia - Los Ntawm Ntu thiab Ntau - ntu cov khoom siv kab rov tav, thiab cov ntaub ntawv pov tseg tau siv ntau yam - cov ntaub ntawv cov ntaub ntawv tsuas los tsim cov mapping relationship between the block reconstruction effect and the geology - engineering sweet - spot index parameters, and has been widely used in reservoir reconstruction. This paper aims to construct a data - driven model based on drilling and logging data to realize the intelligent optimization of section - by - section and multi - cluster differential fracturing parameters for shale gas horizontal wells.
Kev tshuaj xyuas cov ntaub ntawv nyob rau hauv cov ntaub ntawv tsis zoo Ntaus - 2 fuzzy logic overcomtoms Cov kev txwv ntawm cov kev ua tswv cuab. gisussian Foose Cov Tswv Cuab Ua Haujlwm tau muab faib ua tus thawj xibfwb sib txawv, thiab cov Kev ua tswv cuab Matrix yog tsim .} Kev ntsuas lub cev ua haujlwm thiab tsim qhov hnyav matrix matrix tau txais los ntawm compounding qhov hnyav matrix thiab cov tswv cuab matrix, thiab cov k - medows clustering algorithm yog siv los ua kom zoo ntawm fracturing kev siv.
Kev ua kom txawj ntse ua kom zoo ntawm kev siv tshuab - Kev kawm cov txheej txheem ua qauv thiab muaj kev tshaj tawm cov txheej txheem thiab muaj qhov hnyav thiab kev tsis ncaj ncees tshiab.} fracturing parameter Cov qauv ntse optimeedize PDAMS (particle optimization) yog qhov ntsuas pom tau zoo li cov hom phiaj, raws li cov phiaj xwm dnological yog qhov zoo tshaj plaws yog qhov kev ua kom zoo tshaj plaws yog cov phiaj xwm, thiab cov ntaub ntawv - cov ntaub ntawv tsim nyog ua kom tau zoo rau Seem - los ntawm - ntu thiab pawg - los ntawm txoj haujlwm siv thiab kev tsim kho cov tsis tau ntawm cov pob txha pob zeb loj tau tsim.
Daim teb thov noj lub tob tob - txheej Shaale ReservoSirs ntawm cov neeg kho tshuab Los ntawm kev tsom xam ntawm cov qauv ntaub ntawv, kev ntseeg tau ntawm cov kev tsim kho cov khoom siv, thiab cov khoom siv Swarmericy Opecture, thiab cov khoom siv hluav taws xob nruab nrab ntawm thawj lub teb chaws thib 8 ntu raws li tau nce ntxiv 73 {{. 1%, qhia tau tias hom kev ua tau zoo ntawm cov roj qab zib uas muaj txiaj ntsig zoo ntawm cov roj av zoo nkauj thiab cov ntaub ntawv sau cia.
Cov Lus Qhia Txog Qhov Tseeb - Engineering txhais tau tias kev ntsuas tus qauv ruaj khov, thiab muaj peev xwm muab cov khoom ua ntej ntawm cov ntaub ntawv - los ntawm ntu thiab pawg - los ntawm kev sib txuas ntawm kab rov tav Wells thiab optimization ntawm kev siv tsis muaj. Cov ntaub ntawv ntawm cov lus qhia tshiab ntawm cov qauv kev ua kom zoo nkauj rau shale roj kab rov qab rau kev tho thiab Cov ntaub ntawv nkag siab muaj cov ntawv thov siab thiab cov kev txhawb nqa cov zeem muag thiab muab cov kev tshawb fawb tshiab rau shale gas.
