提高石油开采设计的三维地震监视(Three-dimensional Seismic moni-toring of an enhanced oil recoveryproject)R.J.Greaves,eto (S16.1) 我们在提高石油开采设计中。采用了三维地震勘探监视这一过程,该过程是通过现场注入天然气进行燃烧来促进的。在最初的燃烧步骤开始之前,就已经记录了基本测线的三维数据。燃烧了一段时间之后,再反复进行三维测量。由于追踪燃烧步序效应的基础是作比较,因而要特别注意重复的野外观测系统,记录参数,以及数据处理。还要记录垂直地震剖面数据,用它可精确地确定目的砂岩层的反射时间和特征。在进行三维数据分析之前,采用某些模
Three-dimensional Seismic moni-toring of an enhanced oil recovery project R.J.Greaves, eto (S16.1) We are in the process of improving the design of oil extraction. The 3D seismic surveying and monitoring process was used and the process was facilitated by injecting natural gas into the field for combustion. Three-dimensional data of the basic survey line has been recorded before the initial combustion step begins. Burning for some time, and then repeated three-dimensional measurements. Due to the comparisons on the basis of tracking the effects of combustion steps, special attention should be paid to repeated field observations, recording parameters and data processing. Vertical seismic profile data is also recorded, which can be used to accurately determine the reflection time and characteristics of the target sandstone formation. Some modules are used before three-dimensional data analysis
