【摘要】：探讨杂卤石定量预测的技术方法流程。四川盆地三叠系是杂卤石矿的主要产出层段,但因埋藏深(1~4km)、厚度薄(单层厚度1m),勘探难度大。针对杂卤石的特征,从地震勘探角度出发,采用层拉平技术、"印模法"、地震多属性分析技术、井震协同反演技术相结合,进行各种地震勘探技术研究,总结出一套适用于杂卤石定量预测的技术方法流程。杂卤石的成因、运移以及与断层的关系复杂,通过采用高分辨率AFE技术对其进行叠后裂缝预测,认为川东地区杂卤石与裂缝有关。
[Abstract]:This paper discusses the technical process of quantitative prediction of mixed halides. Triassic is the main producing section of the complex halogenite deposits in Sichuan Basin, but because of the buried depth of 1km ~ (-1) and thin thickness (single layer thickness of 1m ~ (-1)), it is difficult to explore. In view of the characteristics of mixed halides, this paper sets out from the point of view of seismic exploration. With the combination of leveling technique, impression method, seismic multi-attribute analysis technique and well seismic co-inversion technique, various seismic exploration techniques are studied, and a set of technical methods for quantitative prediction of mixed halogen are summarized. The migration and the relationship with faults are complicated. By using high-resolution AFE technique to predict post-stack fractures, it is considered that the heterohalite in East Sichuan is related to fractures.
