自济阳坳陷中生代地层发现油气藏以来,对其勘探日益活跃。该地层为陆相碎屑沉积,夹有发育的火成岩和煤。由于成岩后生作用使砂岩、火成岩的矿物成分、孔隙结构、渗透性等发生很大变化,从而具有十分复杂的地质特点。按常规的数字处理进行解释,将存在如何检查与评价所设计的解释模型和算出的各项地质参数的可靠性,以及如何合理地选择与调整带有经验性的计算参数等问题。这正是常规处理方法的弱点。
Since the discovery of oil and gas reservoirs in Mesozoic strata in Jiyang Depression, their exploration has been increasingly active. The formation is continental clastic sediments, with developed igneous rocks and coal. Due to diagenesis, the mineral composition, pore structure and permeability of sandstone and igneous rock have greatly changed, which has very complicated geological characteristics. As explained by conventional digital processing, there will be problems of how to check and evaluate the interpretation model and the calculated reliability of each geological parameter, and how to reasonably select and adjust parameters with empirical calculation. This is the weakness of the conventional approach.
