致密砂岩气藏具有低渗透、连通性差的特点,储层评价研究水平是有效开发该致密砂岩气藏的关键因素。我国在致密砂岩气藏储层特征以及有效储层的识别方面积累了大量的经验。致密砂岩气藏主要指发现与盆地中心以及连续分布大面积的天然气藏。本文主要阐述了致密砂岩气藏储层特征以及有效储层的识别技术。
Tight sandstone gas reservoirs are characterized by low permeability and poor connectivity. The research level of reservoir evaluation is the key factor for the effective development of this tight sandstone gas reservoir. China has accumulated a great deal of experience in the characterization of tight sandstone gas reservoirs and the identification of effective reservoirs. Tight sandstone gas reservoirs mainly refer to the discovery and basin centers and the continuous distribution of large-area natural gas reservoirs. This paper mainly expounds the reservoir characteristics of tight sandstone gas reservoirs and the identification technology of effective reservoirs.
