地震沉积学由于受地震分辨率的限制,往往不能定量刻画沉积体的特征,高精度的反演突破了地震传统分辨率的极限,将其引入到地震沉积学的研究领域,能够解决复杂地质条件下的隐蔽圈闭识别问题,从而拓展了地震沉积学的应用范围、改善应用效果。本文采用地震相控非线性随机反演作为核心技术,以地震沉积学理论为主体思路,应用于胜利油田车镇凹陷Es 3段砂砾岩体储层预测,编制了多期砂砾岩体的厚度分布图与沉积微相图,预测了多个隐蔽圈闭目标,经钻探后得到证实,取得了好的应用效果。
Due to the limitation of seismic resolution, seismic sedimentology often can not quantitatively characterize sedimentary bodies. The high-precision inversion breaks the limit of traditional resolution of seismic and introduces it into the research field of seismic sedimentology, which can solve complex geological conditions Under the hidden trap identification problems, thus expanding the scope of application of seismic sedimentology, to improve the application effect. In this paper, seismic phase-controlled nonlinear stochastic inversion is used as the core technology. With the theory of seismic sedimentology as the main idea, this paper is applied to the prediction of the Es 3 member glutenite reservoir in Chezhen depression, Shengli Oilfield. The thickness distribution of multi-period glutenite bodies Figure and sedimentary microfacies map, predict a number of hidden trap target, confirmed by drilling, and achieved good results.
