基于多次注入剖面测井的储层状况评价技术及其应用

RESERVOIR EVALUATING TECHNIQUE BASED ON THE MULTIPLE INJECTED PROFILE LOGGING AND ITS APPLICATION

注入剖面测井资料是油田注水开发过程中分析储层吸水状况的主要依据。从注入剖面动用厚度和均匀程度两个方面,给出基于多次注入剖面资料评价储层动用状况的方法。利用动态监测数据库资源设计了包含储层状况各种动静态属性的新数据表,通过软件实现储层动用状况评价方法和新数据表,开发了一个高效、可视化的储层动用状况分析工具。该研究技术在指导区块或单井方案编制和措施选井选层及效果对比中得到广泛应用。

The injected profile logging data is the main evidence of analyzing the reservoir water absorption conditions during the process of the oilfield development. From the viewpoints of the developed thickness and uniformity of the injected profiles,the evaluating method of the reservoir produced conditions was established on the basis of the multiple injected profile data. Using the dynamic monitoring database resources,a new data table is designed,which contains the dynamic and static properties of the reservoir conditions,and moreover with the help of the software,the evaluating method and new data table were realized,thus the high-efficiency and visualized analyzing tool of the reservoir produced status was developed. The technique was widely applied to guide the program makings of both the individual wells and blocks,well or layer optimization and effects comparison of the stimulated wells.
