随着石油勘探研究的不断深入,砂岩透镜体油藏日益受到重视。国内外学者提出了多种成藏机制,包括未知重力运动机制作用下,少数流体分子的个别特性控制透镜状砂岩油藏聚集;毛细管力作用下油气替换透镜体中的孔隙水;烃浓度差是油气向砂体运移的主要动力;流体压力差使油气首先沿着裂隙向砂岩透镜体中运移、聚集而成藏;差异突破作用使砂岩透镜体成藏等。成藏动力学、成藏模式及主控因素、定量研究、物理模拟实验、数值模拟及分布预测等将是今后发展的方向。
With the deepening of oil exploration research, sandstone lens reservoirs have received increasing attention. Domestic and foreign scholars have proposed a variety of accumulation mechanisms, including the unknown gravity movement mechanism, the individual characteristics of a small number of fluid molecules control the accumulation of lenticular sandstone reservoirs; oil and gas by capillary forces to replace the pore water in the lens body; hydrocarbon concentration difference is Oil and gas to the sand body migration of the main driving force; fluid pressure difference so that the oil and gas first along the fissure sandstone lens body migration, accumulation and accumulation; differential breakthrough sandstone lens body accumulation. Accumulation dynamics, reservoir forming modes and main controlling factors, quantitative research, physical simulation experiments, numerical simulation and distribution forecasting will be the future development direction.
