影响稠油油藏底水锥进的主要参数研究

Main parameters affecting bottom water coning in heavy oil reservoir

为提高中深层底水油藏的开发效果,并为编制注水开发调整方案提供地质依据,利用正交设计方法对高246断块影响底水锥进的典型参数进行了敏感性分析,应用解析法和数值模拟法剖析了各参数对该区块开发效果的影响。结果表明,避射厚度、生产压差、临界产量等是影响底水锥进的关键参数。

In order to improve development in mid - deep bottom water reservoir and provide geological basis for formulating adjustment plan of water flooding, the sensitivity of typical parameters affecting bottom water coning in Gao 246 fault block has been analyzed through orthogonal designing method, and the influence of each parameter on development effect has been analyzed by analytical method and numerical simulation. The result is that key parameters affecting bottom water coning are thickness of unperforated interval, producing pressure differential and critical output.
