1深层天然气理论与技术创新支撑克拉苏大气区的高效勘探开发。主要创新包括:通过模拟实验与地震剖面精细解译,建立了同一应力机制下含盐前陆冲断带的构造样式,确定了深层盐下叠瓦冲断构造特征;建立了储集层发育模式,创新认识了盐下白垩系砂岩4 500 m以下储集层成因机理,并预测有效储集层深度超过8 000 m;建立了巨厚膏盐层下高效聚气的成藏模式和超深超高压气藏高效开发模式;形成了含盐前陆冲断带宽线大组合地震采集、三维各向异性叠前深度偏移、山前超深超高压高温钻井提
Deep gas theory and technological innovation support the efficient exploration and development of the Karasu atmosphere. The main innovations include: The structural model of the salt-bearing foreland thrust belt under the same stress mechanism is established through the detailed interpretation of simulation experiments and seismic profiles, the tectonic features of deep sub-salt shoal thrust faults are established, and the reservoir development model , And discovered the genesis mechanism of reservoirs below 4 500 m in Cretaceous sandstone of the submarine and predicted that the effective reservoir depth is more than 8 000 m. High-pressure gas reservoir high-efficiency development model; formation of the salt-bearing foreland thrust belt broad line seismic acquisition, three-dimensional anisotropy prestack depth migration, piedmont ultra-deep high pressure high temperature drilling
