引言振幅与炮检距关系分析(AVO),对得克萨斯州墨西哥湾沿岸地区的勘探产生了令人瞩目的影响。在成熟探区和降低钻井风险方面,开辟了新的方向。因此,即使是小的单井勘探目标,在经济上也变得更具有吸引力。从1987年到1991年间,利用AVO分析始新统Yegua和Cook Mountain走向带的岩性圈闭内发现,天然气地质储量约为300亿ft~3。与此同时,在得克萨斯州陆L地区,对始新统/古新统间的Wilcox层应用AVO的尝试却似乎是失败的。根据该区对AVO异常进行钻探的大
Introduction Amplitude vs. Offset Analysis (AVO) has had a dramatic impact on exploration in the Texas Gulf Coast. In the mature exploration and reduce drilling risk, has opened up a new direction. As a result, even small, single-well exploration targets have become more economically attractive. From 1987 to 1991, using AVO to analyze the lithologic traps in the Eocene Yegua and Cook Mountain strike zones, it was found that the geological reserve of natural gas is about 30 billion ft 3. At the same time, attempts to apply AVO to the Wilcox layer between the Eocene / palaeocene strata in the L region of Texas seem to have failed. According to the area on the abnormal AVO drilling large
