摘　　要：长庆油田低渗透储层发育,随着勘探开发的不断深入,储层渗透性逐渐变差,需要开展更加精细的地质研究工作。储层物性是油藏各种因素的综合表征,主要受沉积环境、胶结物含量、微观孔隙结构等因素影响。明确影响延长组储层物性的主要因素,可为油田开发部署及开发政策制定提供可靠的帮助。With the development of the petroleum exploration in Changqing Oilfield, the reservoir permeability gradually becomes poor, so fine geologic research is necessary for the further development. The reservoir properties are mainly affected by depositional settings, cement content and micro-pore structure, etc. To definite the main influencing factors for the reservoir property could take a significant part in guiding the exploration and development in Changqing Oilfield.
