多信息耦合的水平井井间隔夹层预测方法

综合利用岩心、常规测井、倾角测井、水平井测井和生产动态等资料,对塔里木盆地哈得逊油田东河砂岩隔夹层的静态地质特征、产状拾取、水平井测井响应特征、动态生产特征等进行系统研究。通过"静态模式指导、多测井系列解释、产状指向、水平井标定、导眼井与水平井匹配、动态预测及验证"的流程,建立有创新性和针对性的多信息耦合的水平井井间隔夹层预测方法。结果表明:研究区存在泥质、钙质和钙泥质隔夹层,从级次上分为层间、砂体间及单砂体内隔夹层;优选0. 2 m窗长、0. 02 m步长、30°探索角拾取隔夹层的产状,并进行产状转换;通过水平井段测井响应异常及深浅电阻率差异识别隔夹层的类型及位置;将研究区射孔及见效情况、含水率及日产液曲线进行分类,确立连续、半连续、不连续3类隔夹层展布范围及平行、倾斜两种隔夹层展布产状对应的注水区、边水区、底水区的单井生产动态特征。

多信息耦合的滨岸相单砂体划分方法——以哈得逊油田东河砂岩为例

塔里木盆地哈得逊油田是我国第一个亿吨级海相碎屑岩油田,主力产层是滨岸相东河砂岩,由于缺乏单砂体的精细划分研究,存在近距离内注水不受效,油水界面具有100多米的高程差等难以解释的问题（赵洪等,2014）。

Second-Order Consensus of Multiple Agents with Coupling Delay

In this paper, we investigate two kinds of second-order consensus algorithms for multiple agents with coupling delay under general fixed directed information topology. Stability analysis is performed based on Lyapunov- Krasovskii functional method. Delay-dependent asymptotical stability condition in terms of linear matrix inequalities （LMIs） is derived for the second-order consensus algorithm of delayed dynamical networks. Both delay-independent and delay-dependent asymptotical stability conditions in terms of LMIs are derived for the second-order consensus algorithm with information feedback.
