随着垂直地震剖面(VSP)技术的持续发展进步,在不同探区完成的VSP项目越来越多.根据油田公司勘探的需要,少量钻井进行了不同时期的两次VSP采集,个别井存在多次采集的情况,这为研究井筒附近各种地球物理属性随时间变化提供了宝贵的研究资料.以准噶尔盆地、塔里木盆地各一口有代表性的井为实例,分析了井旁目的层的地震反射特征、地球物理属性特征等随时间的变化情况,并结合相应的钻采资料,分析了引起储集层发生变化的主要因素,为油气储层研究和油气田勘探开发提供了依据. With the continuous development of vertical seismic profile (VSP) technology, more and more VSP projects are completed in different exploration areas.According to exploration needs of oilfield companies, a small number of drilling carried out two times of VSP acquisition in different periods, and there are many individual wells This provides valuable research data for studying various geophysical properties near the wellbore with time.A typical well in Junggar basin and Tarim basin is taken as an example to analyze the seismic reflection Characteristics and geophysical characteristics of the reservoir over time, combined with the corresponding drilling data, analyzes the main factors that cause the reservoir to change, and provides the basis for the study of oil and gas reservoirs and exploration and development of oil and gas fields.
