沾车地区沙四段湖相碳酸盐岩的地震识别与预测
|
摘要
本文以沾车地区沙四段湖相碳酸盐岩为研究对象,在沉积环境分析的基础上,提出了沾车地区沙四段湖相碳酸盐岩的三类亚相分类方案,即该区湖相碳酸盐岩可分为三类亚相:生物礁、颗粒滩、灰泥。根据发育部位将生物礁分为盆缘断阶型生物礁、斜坡高部位型生物礁、坡折带高能型生物礁。在以上沉积亚相研究的基础上,通过湖相碳酸盐岩模型特征的定量识别,明确了不同亚相储层与关键地震参数的定量关系;通过高精度地震古地貌恢复技术和波形分类技术预测了湖相碳酸盐岩的亚相发育区;通过分频地震属性技术和裂缝预测技术等综合地球物理手段,对该区碳酸盐岩有利储层及裂缝发育区进行了预测。钻井验证了预测结果的正确性。
In this paper the lacustrine carbonate at Es4 in Zhanche Area is the study object,based on the analysis of sedimentary environment,three subfacies classification schedule was presented in this paper,the three subfacies are the reef,the granular beach and the lime-mud.Based on development areas,the reef subfacies can be divided into the basin-marginal fault terrace,the height of slope,and the high productivity slope break.Based on the subfacies studies above,the quantitative relationship between different subfacies and key seismic parameters was determined through the quantitative identification for the model characteristics of the lacustrine carbonate,and the subfacies development areas of the lacustrine carbonate were predicted through high precision paleogeomorphology recovery technique and waveform classification technique,while the prediction of the favorable reservoir and fracture development areas were conducted through frequency division attribute technique and fracture prediction technique.The drilling for the targets proved the effectiveness of the studies.
