在加利福利亚重油砂蒸汽驱的早期阶段,就已经用S波、P波以及泊松比层析成象来解释岩石和流体特性的三维分布。在四天里,布置了四条测线,炮检距范围从287～551英尺,以围绕高温水泥接收电缆的径向排列方式采集到高质量的井中地震数据。尽管在长测线与短测线之间存在着与偏移距有关的数据质量偏差,我们还是完成了数据处理,初至波拾取,并重建了高质量的层析图象。在对比油藏模型、测井、岩芯、温度,以及蒸汽注入数据的基础上,进行了数据解
In the early stages of California heavy oil sands steam flooding, S-wave, P-wave and Poisson ratio tomographic imaging have been used to account for the three-dimensional distribution of rock and fluid properties. In four days, four survey lines were deployed with offset distances ranging from 287 to 551 feet to obtain high-quality well bore seismic data around the radial arrangement of high-temperature cement receiving cables. Despite skewed data quality deviations between long and short lines, we completed data processing, first-arrival pick-up, and reconstructed high quality tomograms. Based on the data of reservoir model, logging, core, temperature, and steam injection, the data solution
