井间示踪测试中筛选示踪剂的方法

Method of selecting tracer in the inter-well tracer test

井间示踪测试的研究对象是井间关系,它的研究成果反映了更大范围内的油层特性和油水井间的关系,因此示踪剂的开采动态反馈了油藏非均质特征及开发过程中注入流体分布的信息,是油田管理及动态调整的重要依据。示踪剂的物理化学特性及其与油层岩石和流体的相互作用程度,直接影响示踪剂的流动特性,它直接关系到示踪剂能否跟踪注入流体,反馈注入流体的流动特性,并对最终解释结果产生影响。因此,选择出适合本油田示踪测试的示踪剂,是井间示踪测试的重要环节。本文阐述了示踪剂的分类及其应用,根据最终目的选择示踪剂的标准,并结合实例,介绍了最后确定选用示踪剂的方法。

The study object of inter-well tracer test is the relationship between wells, and its research reflects a greater range of reservoir characteristics and the relationship between the oil wells, so the development of tracer exploitating feedbacks the heterogeneity of the reservoir and the information of injected fluid distribution in the developing process, and it is an important basis of field management and dynamic adjustment. The physical and chemical properties of tracer and its interaction level of reservoir rock and fluid directly affect the flow characteristics of tracer, it is directly related to the ability of the tracer to track injected fluid, feedback the flow characteristics of intejected fluid, and impact the final interpretation. Therefore, choosing a suitable tracer in this field tracer test is the important part of inter-well tracer test, In this paper, the classification of tracer and its application, and the criteria of selecting tracer in accordance with the ultimate goal are expounded, also combining with examples, the method of final selection tracer is introduced.
