【摘要】 以辽河油田龙10块沙三段下亚段为例,结合开发中后期密井网条件下对宽度、厚度和体积分数等各沉积微相参数的认识,利用波阻抗与沉积微相之间的概率关系,应用序贯指示同位协同模拟算法,建立了储层沉积微相模型。实践结果证实,该方法能够对相变较快的陆相储层井间沉积微相的不确定性进行表征,提高模型预测的可靠性。更多还原

【Abstract】 Applying the analog algorithm of coordinate collaboration by sequential indicating establish sedimentary microfacies model in lower Es3 of Long 10 block in Liaohe Oilfield with the probability relation of acoustic impedance and sedimentary microfacies. Its foundation is the knowledge of each sedimentary microfacies parameter of width, thickness and volume content in the condition of close spacing in middle and later period of oilfield development. The practice proves that using this method could characterize the uncertainty of sedimentary microfacies changed soon a-mong wells in continental reservoirs, and enhance the reliability of model forecast.更多还原
