    • A method and associated apparatus continuously optimizes reservoir, well and surface network systems by using monitoring data and downhole control devices to continuously change the position of a downhole intelligent control valve (ICV) (12) until a set of characteristics associated with the "actual" monitored data is approximately equal to, or is not significantly different than, a set of characteristics associated with "target" data that is provided by a reservoir simulator (32). A control pulse (18) having a predetermined signature is transmitted downhole thereby changing a position of the ICV. In response, a sensor (14) generates signals representing "actual" monitoring data. A simulator (32) which models a reservoir layer provides "target" data. A computer apparatus (30) receives the "actual" data and the "target" data and, when the "actual" data is not approximately equal to the "target" data, the computer apparatus (30) executes a "monitoring and control process" program code which changes the predetermined signature of the control pulse to a second and different predetermined signature. A new pulse having the second predetermined signature is transmitted downhole and the above process repeats until the "actual" data received by the computer apparatus (30) is approximately equal to the "target" data.
    • 一种方法和相关设备通过使用监测数据和井下控制装置连续地改变井下智能控制阀(ICV)(12)的位置,直到与“实际” 所监视的数据大约等于或不显着不同于由油藏模拟器(32)提供的与“目标”数据相关联的一组特征。 具有预定签名的控制脉冲(18)在井下传输,从而改变ICV的位置。 作为响应,传感器(14)产生表示“实际”监视数据的信号。 对储层进行建模的模拟器(32)提供“目标”数据。 计算机装置(30)接收“实际”数据和“目标”数据,当“实际”数据近似等于“目标”数据时,计算机装置(30)执行“监视和控制处理 “程序代码,其将控制脉冲的预定签名改变为第二和不同的预定签名。 具有第二预定签名的新脉冲在井下传输,并且上述处理重复,直到由计算机装置(30)接收的“实际”数据近似等于“目标”数据。
