摘　　要：试井技术是一项重要的油田开发技术,是注采开发方案调整、措施选井及评价、精细油藏描述的基础,被形象誉为油田开发者的"听诊器"。本文针对侏罗系均质油藏和三叠系人工压裂井,从试井曲线特征入手,结合储层特征分析其成因,认识低渗透油藏渗流规律;并将其应用于油田开发,除常规评价能量分布指导注采调整外,也可评价油田开发技术政策、识别水驱前沿及评价水驱效果、指导多层开发和各类措施挖潜与评价,逐步形成了配套的低渗透油藏试井技术应用模式,高效指导油田开发。Well testing is an important technology in oil field development, and it is also the foundation of the adjustment of injection and development program, of the evaluation and selection of the measure and of the fine reservoir description, which is considered as the ＂stethoscope＂ of the oil field. This paper is based on the heterogeneous reservoir of Jurassic and fractured wells of the Triassic, through the characteristics of the testing curves, combining with the characteristics of the reservoir to analyze the causes of it and recognize the law of low permeability reservoir; and applied to the oil field development, in addition to routine evalua- tion of energy distribution and the guidance of injection and adjustment, which can value the development and technology policy of oil field, besides it can also recognize the front and the effect of water injection; it can guide multi-storey explore and tap the potential and evaluation of various measures, which gradually form the application model of well testing in low permeability reservoir and guide the development of oil field effectively.
