【摘要】：正頁巖作為一種非常規(guī)油氣儲集巖,它的孔隙狀結(jié)構(gòu)特征與常規(guī)儲層差異較大,因此常規(guī)孔隙結(jié)構(gòu)表征方法對其孔隙的刻畫往往并不準(zhǔn)確。近年來發(fā)展的核磁共振技術(shù)在測井以及表征孔隙結(jié)構(gòu)等油氣勘探領(lǐng)域有著廣泛的應(yīng)用,逐漸成為重要的儲層評價方式。核磁共振法測定孔徑分布是根據(jù)巖石飽和單相流體的核磁共振T_2譜可以反映其孔隙內(nèi)部結(jié)構(gòu),并通過孔徑與其中流體的馳豫時間T_2的正相關(guān)關(guān)系來進(jìn)行換算獲得。巖石孔隙流體的T_2與孔隙
[Abstract]:As a kind of unconventional oil and gas reservoir, the pore structure of normal shale is quite different from that of conventional reservoir, so the characterization of pore structure by conventional pore structure is often inaccurate. Nuclear magnetic resonance (NMR) technology developed in recent years has been widely used in oil and gas exploration fields such as logging and characterization of pore structure and has gradually become an important reservoir evaluation method. The determination of pore size distribution by nuclear magnetic resonance (NMR) method is based on the NMR T _ 2 spectrum of saturated single-phase fluid, which can reflect the pore structure of rock saturated single-phase fluid, and can be obtained by the positive correlation between pore size and relaxation time T _ 2 of the fluid in it. T _ 2 and pore of pore fluid in rock
