光刻显微模型是国外近几年来研究残余油形成机理使用的一种较先进的物理模型。目前国内外进行此类研究,主要是采用实际油层取心和模型实验(物理和数学模型)两种方法。用实际岩心作实验,比较接近油层实际,但研究成果是经验统计性的,往往只知其然不知甚所以然;模型实验虽与油层实际有一定差距,但它既可以直接观察流体的排驱过程,又可以将实际岩石的各种孔隙结构特征抽象出来,单独模拟。使我们有可能从驱油机理上去直观地研究流体的排驱过程。1986年我校地质系曲志浩副教授,在前几年进行的人工刻蚀模型实验研究成果的基础上,与航天部691厂工程师贾建国同志密切合作,经反复试验,制成了一种具有国内外先讲水平的粘结光刻显微模型。
Photolithography microscopy model is a more advanced physical model used abroad to study the formation mechanism of residual oil in recent years. At present, both domestic and international researches are mainly based on two methods of actual coring and model experiments (physical and mathematical models). Experiments with actual cores are relatively close to the reality of oil reservoirs, but the research results are empirical and often only known to some extent. However, although the model experiment has a certain gap with the reservoir, it can directly observe the process of fluid displacement , But also abstract the various pore structure characteristics of the actual rock and simulate it separately. It is possible to study the fluid discharge process intuitively from the mechanism of oil displacement. Associate Professor Qu Zhihao, Department of Geology, our school in 1986, based on the experimental results of artificial etching model conducted in previous years, worked closely with Comrade Jia Jianguo, engineer of 691 plant of the Ministry of Aeronautics and Astronautics. Through repeated experiments, At home and abroad to speak about the level of bonding photolithography microscopic model.
