    • A method for determining flow distribution in a formation having a wellbore formed therein includes the steps of positioning a sensor within the wellbore, wherein the sensor generates a feedback signal representing at least one of a temperature and a pressure measured by the sensor, injecting a fluid into the wellbore and into at least a portion of the formation adjacent the sensor, shutting-in the wellbore for a pre-determined shut-in period, generating a simulated model representing at least one of simulated temperature characteristics and simulated pressure characteristics of the formation during the shut-in period, generating a data model representing at least one of actual temperature characteristics and actual pressure characteristics of the formation during the shut-in period, wherein the data model is derived from the feedback signal, comparing the data model to the simulated model, and adjusting parameters of the simulated model to substantially match the data model.
    • 一种用于确定其中形成有井眼的地层中的流动分布的方法包括以下步骤:将传感器定位在井眼内,其中传感器产生表示由传感器测量的温度和压力中的至少一个的反馈信号;注入流体 进入井筒并进入与传感器相邻的地层的至少一部分中,在预先确定的关井周期中关闭井眼,产生表示地层的模拟温度特性和模拟压力特性中的至少一个的模拟模型 在关闭时段期间,生成表示在关闭时段期间地层的实际温度特性和实际压力特性中的至少一个的数据模型,其中数据模型从反馈信号中导出,将数据模型与 模拟模型,以及调整模拟模型的参数以基本匹配数据模型。
