【摘要】：頁(yè)巖儲(chǔ)層的儲(chǔ)集空間主體為納米級(jí)孔隙-裂隙系統(tǒng),僅在局部發(fā)育微米—毫米級(jí)孔隙。隨著以頁(yè)巖油氣、致密油氣為代表的非常規(guī)油氣資源成為全球油氣勘探開發(fā)的新熱點(diǎn),納米尺度下的液體流動(dòng)機(jī)理研究引起了國(guó)內(nèi)外學(xué)者的廣泛關(guān)注。通過大量的文獻(xiàn)調(diào)研,對(duì)納米尺度下液體的流動(dòng)特征進(jìn)行了系統(tǒng)總結(jié),分析了目前常用的物模實(shí)驗(yàn)、分子動(dòng)力學(xué)模擬和直接Monte Carlo模擬等研究手段的基本原理和優(yōu)缺點(diǎn),并從實(shí)驗(yàn)和模擬兩大方面介紹了納米孔隙內(nèi)液體流動(dòng)機(jī)理研究的最新進(jìn)展及成果。在此基礎(chǔ)上,探討了納米尺度下液體流動(dòng)機(jī)理研究對(duì)頁(yè)巖油勘探開發(fā)的啟示,指出分子動(dòng)力學(xué)模擬方法是開展頁(yè)巖儲(chǔ)層納米級(jí)孔隙系統(tǒng)內(nèi)原油流動(dòng)機(jī)理研究的必然選擇,同時(shí)需要進(jìn)一步推進(jìn)納米尺度流動(dòng)的實(shí)驗(yàn)方法研究。
[Abstract]:The main reservoir space of shale reservoir is nanometer porosity-fracture system, and only micrometer pore is developed in the local area, along with shale oil and gas. Unconventional oil and gas resources represented by dense oil and gas have become a new hot spot in global oil and gas exploration and development. The study of liquid flow mechanism at nanometer scale has attracted extensive attention of domestic and foreign scholars. The characteristics of liquid flow in nanoscale are summarized systematically, and the commonly used physical model experiments are analyzed. The basic principle, advantages and disadvantages of molecular dynamics simulation and direct Monte Carlo simulation. The latest progress and achievements in the study of liquid flow mechanism in nano-pore are introduced from two aspects of experiment and simulation. On this basis, the enlightenment of the study on the mechanism of liquid flow in nano-scale to the exploration and development of shale oil is discussed. It is pointed out that molecular dynamics simulation method is an inevitable choice to study the flow mechanism of crude oil in shale reservoir nanoscale pore system, and it is necessary to further advance the experimental study of nano-scale flow.

【正文快照】： 0引言目前,世界石油工業(yè)正在由常規(guī)油氣資源向非常規(guī)油氣資源跨越。以頁(yè)巖油氣、致密油氣為代表的非常規(guī)油氣資源逐漸成為全球油氣勘探開發(fā)的新熱點(diǎn)[1-3]。與常規(guī)油氣藏相比,泥頁(yè)巖、致密砂巖、致密碳酸鹽巖等非常規(guī)儲(chǔ)集層具有特殊的微納米級(jí)孔喉-裂隙系統(tǒng),因而表現(xiàn)出強(qiáng)烈的非
