疏松砂岩油藏大孔道形成机理及判别方法

The Macroscopic Throats Forming Mechanism of Unsolidated Sand-reservior and Their Identyfying Method

动用填砂玻璃板模型对疏松砂岩油层大孔道形成机理进行物理模拟 ,探讨了沉积特征、油层物性、开发过程等因素对大孔道形成的影响 ,归纳了大孔道形成的因素模型及大孔道形成过程中的产量压力特征 .以渗流力学原理和油气工程方法为指导 ,提出了描述大孔道的数学模型 ,运用灰色关联理论和常规动态资料识别描述油层大孔道 。

In the thesis,sand packed glass plate model was applied to physical simulation of the macroscopic throats forming mechanism, studied effects of these factors a ssedimental characteristics, petrophysical property,production process etc. ont he forming of macroscopic throats. Guided by dynamics of fluids through porou s m edia and oil reservior engineering, macroscopic throats mathematical model w as p ut formard, and by employing grey correlation correctly on the computer.
