火山岩气藏三维地质模型不确定性分析
|
摘要
通过影响三维地质模型不确定性诸多因素的分析,提出了"定源→定体→定旋回"火山岩成因层次描述方法。合成地震记录与叠加速度联合构建三维空变速度场方法、多属性协同随机模拟方法和储层预测不确定性分析方法,突出了火山岩成因和成储、成藏机制,客观反映了三维地质模型中包含的不确定性,最大限度降低了构造和储层预测不确定性。通过优选构造和储层发育的有利部位,部署并实施了多口水平井,取得了较好的实际应用效果。
By analyzing the influential factors to the uncertainty in the 3D geological models,a series of methods and technologies are presented including volcanic reservoir genesis description of "Source,Body,Cycle",3D velocity field establishment with combination of synthetic seismograms and stacking velocity,stochastic simulation constrained by multi-attributes,and uncertainty estimation.The 3D structure and reservoir models established by the methods and technologies above can highlight the genesis and the reservoir-forming mechanism of volcanic,can objectively reflect the uncertainty in the 3D geological model,and can decrease the uncertainty of structure and reservoir prediction in volcanic to greatest extent.By optimizing the favorable positions of structure and reservoir,the horizontal wells are deployed and implemented,and give a good application effect.
