岩性油气藏地震勘探若干问题讨论(Ⅰ)
|
摘要
20世纪90年代以来,中国的石油勘探已进入岩性油气藏的勘探开发阶段。在岩性油气藏勘探过程中,遇到了一些新的、令人困惑的难题。该文对地震反射同相轴与沉积等时面的关系作了讨论,认为在岩性油气藏勘探追踪砂体时必须重视波阻抗反演,并对钙质致密砂岩的波阻抗解释也作了进一步的讨论。
Since the 1990's, petroleum exploration in China has come to a stage of lithologic reservoirs. Nevertheless, during the course of the lithologic reservoir exploration, some new and puzzling problems emerged. The relationship between the pseudo line-ups events and isochronous sediment surface is discussed. It is put forward that acoustic impedance inversion must be taken seriously for lithologic reservoir exploration when you were tracing the deeper sand bodies. The acoustic impedance interpretation of calcareous compacted sandstone is also discussed.
