烃源岩孔隙流体介质对石油初次运移的影响
Effect of fluid medium in source rock porosity on oil primary migration
摘要
Abstract
With the self⁃designed simulation instrument for hydrocarbon generation and expulsion in formation porosity under controlled heating and pressuring conditions, a series of experiments was made with different sys⁃tems such as nitrogen-water vapor, water vapor-liquid water, liquid water, and anhydrous. Oil discharge effi⁃ciency was compared to study the effect of the fluid medium in source rock porosity on oil primary migration. In the oil and gas generation phase, pore space in the source rock was charged by fluids ( hydrocarbon gas, non⁃hy⁃drocarbon gas, oil, formation water) with certain temperature and pressure. Liquid water was an indispensable transport carrier in oil primary migration process. Water might adsorb onto the surface of minerals, preventeding the adsorption of hydrocarbon and was favorable for hydrocarbon migration. CO2 associated with hydrocarbon generation easily dissolved in oil, which reduced the interfacial tension between the oil and water, oil viscosity and oil migration resistance, and promoted oil primary migration.关键词
