摘要
传统的测井方法和仪器由于径向探测范围很小,不能很好满足油藏描述和监测方面的需要。井间测量是通过直接测量井间地层与油藏特征,来弥补测井横向探测能力不足,解决井孔与井间采集信息类型和信息丰度不平衡的问题。把地面和井中的地球物理测量结合起来,改变了单纯根据测井资料推演并预测井间油藏属性的传统研究模式。介绍了井间示踪、井间地震和井间电磁成像等测井技术的方法、原理及应用情况。
Traditional well-logging methods and apparatuses fail to meet the need of reservoir description and monitoring due to limited detection range. Cross-hole survey measures the characters of formation and reservoir between two boreholes directly. It can compensate the incapability of well-logging, resolve the inconsistence of information type and information redundancy between wellbore and cross-hole survey, and deduce crosswell reservoir properties by joint surface and wellbore geophysical data. This paper introduced the methodology and applications of cross-hole survey technologies such as crosswell tracing,crosswell seismic, and crosswell electromagnetic imaging.
