摘要
元素俘获谱测井(ECS)是在组成特定矿物的元素种类含量相对固定的储层条件下,通过测量矿物元素确定矿物的含量和类型。在介绍该测井仪器结构、测井原理以及氧化物闭合模型求解矿物原理的基础上,介绍了它在确定矿物类型和含量、估算储层岩石骨架属性、确定地层渗透率,储层沉积环境以及评价储层污染损害等储层综合评价中的应用。尽管该项新型专利技术存在一定的缺陷,但它几乎测出了岩石骨架的全部成份,能够连续准确地确定储层岩性。
Elemental capture spectroscopy (ECS) is used to identify the contents and types of the minerals by measuring the elemental contents of reservoir under the reservoir condition that mineral components are fixed. Introduced are structure, logging principle of ECS tool and principle of getting mineral contents with oxide closure model. On the basis of the above, the types and contents of the minerals can be got and the matrix properties and permeability of reservoir can also be estimated. In addition, the deposit environment and contamination of the reservoir can be appraised. Although the new technology has disadvantage, but it can measure all components of rock framework, identify lithology of reservoir continually and accurately.
