| 摘 要： | 从深部碎屑岩储层次生孔隙的溶蚀机理、溶蚀矿物的种类、影响因素3个方面总结了近年来深部储层次生孔隙的研究成果.深部储层次生孔隙的发育受众多因素影响,异常高压、断裂发育、深部热流体活动、流体交换等都会对次生孔隙的发育产生有益的影响.提出了应该重视深部与中浅层物理化学性质的差别,综合系统地研究深部碎屑岩储层次生孔隙的成因与分布,特别是模拟高温高压条件下矿物溶蚀和沉淀的机理及其影响因素,全面突破深部储层次生孔隙理论,指导勘探开发.

| Abstract: | Porosities, both primary and secondary, are the important places to reserve oil and gas. At present, the study in the genesis and distribution of clastic reservoir porosity almost concentrates on shallow and mid-depth zones. With deep oil and gas being discovered and developed, the mechanism and forecast of secondary porosity in deep zones becomes especially important. This paper, from the corrosion mechanism, variety of corroded minerals and corrosion influence factors, summarizes the advances in deep-reservoir secondary porosity during latest years. It is found that the generation of deep-reservoir secondary porosity can be promoted by many factors, such as abnormal pressure, fracture systems, deep-hot fluids and exchange of fluids. Importance should be attached to the difference in physics and chemistry between shal- low and deep reservoirs in order to make breakthroughs in the exploration and development. Also, every factor should be thought about synthetically and systemically. In addition, the erosion and precipitation of minerals especially needs to be simulated in high temperature and high pressure. |
