摘要
受盆地复杂的石油地质条件影响,珠江口盆地(西部)地震属性的地质含义异常复杂,难以表征储层及含油气性,基于此,文章总结了珠江口盆地(西部)地震属性难以有效应用三个方面:(1)盆地地层呈"千层饼"式互层发育,单层厚度小,难以达到地震分辨率;(2)受压实作用影响及低速泥岩的存在,砂泥岩岩石物理规律不清;(3)局部地区为含灰质地层,进一步复杂化该区砂泥岩岩石物理规律.文章指出了研究人员在该区地震属性应用中的几个误区,在此基础上,提出了针对该区复杂石油地质条件下的地震属性分析思路,并成功运用到预探井的含油气预测中,取得了一定的效果,研究思路值得进一步推广.
It ＇s too difficult to characterize the reservoir and hydrocarbon potential owing to complex petroleum geology conditions and difficult geological implication. Based on the above issues,the article summarizes the complexity of seismic attributes in the Western Pearl River Mouth Basin in the following three aspects：（1）It is difficult to achieve the seismic resolution because basin formation was ＂ pastry ＂ type characterized by interbedded development,small thickness.（2） physics law of mudstone and sandstone are unclear due to compaction affecting and low speed;（3）local area affected calcareous formation and further complicate the sand and shale rock in the area of physical laws. On this basis,the article points out a few errors of seismic attribute applications in the area,and proposed ideas for seismic attribute analysis under the area of petroleum complex geological conditions,and successfully applied to the hydrocarbon prediction and achieved some results,worthy of further promotion.
