摘要
为了验证用地震资料、钻井钻遇断点资料组合出来的小断层结果是否正确，以注入示踪剂资料为依据，以相关理论为指导，利用油水井动态资料计算小断层附近油水井的注入量与产液量之间的相关系数。对砂体连通情况分析后计算出注入采出井之间的连通厚度比例，通过分析相关系数、连通比例与断层存在与否的关系，来验证断层组合的正确性。该方法证实在连通厚度比例大于50％的条件下，相关系数小于0．3的可视为油水井之间存在断层，相关系数大于0．3的则视为不存在断层。
In order to verify the correctness of minor fault identification by the combination of seismic data and breakpoints data from drilling, correlation coefficient of injection rate and liquid producing capacity of the oil wells and water injection wells near the minor faults is calculated by the performance data of oil wells and water injection wells according to the injected tracers data under the direction of correlation theory. The thickness ratio of connected sandstone between injection wells and production wells is calculated after the analysis of connectivity of sand body. The correctness of fault complex can be verified through the analysis of the relationship between correlation coefficient, connectivity ratio and the existence of faults. This method verifies that it is considered that under the condition that the connected thickness ration is larger than 50% , if the correlation coefficient is smaller than O. 3, there will exist faults between oil wells and water injection wells ; if the correlation coefficient is larger than O. 3, there will be no faults.
