摘要:
用地球物理的方法对盖层进行评价和优选报道少见。在TNB地区,盖层条件是油气成藏决定性因素之一。尝试利用属性分析技术对该区膏盐岩盖层进行初步评价,利用波阻抗反演技术和多属性非线性分析技术量化盖层评价参数,成功获取了TNB地区盖层岩性和孔隙度资料,结合现有的勘探认识,确定了TNB地区有效盖层的孔隙度门限和分布范围。相对于测井预测方法,本次预测成果略显简单,但对于测井资料十分缺乏的地区,利用地震属性进行盖层有利区带预测是必要的。
Abstract:
Geophysical technique is seldom applied in caprock evaluation. In TNB area, caprock is one of the key factor in gas reservoir formation. Here, we try to evaluate salt caprock with seismic attributes. The acoustic impedance inversion technique and multi-attribute no-linear analysis were used to quantify stratum properties. The lithology and porosity of caprocks in TNB area were obtained successfully, and the porosity threshold and distribution range of the effective caprocks were further determinated. Compared with logging analysis, the forecast results have low accuracy, however, for the area lacking of logging data, the caprock forecast with seismic attributes analysis is very significant.
