中文摘要:洼38块稠油油藏为辽河小洼油田主力区块。截至2018年,该区块已连续开发27年,主要开发方式为蒸汽吞吐及蒸汽驱。结合开发效果及综合效益,洼38块在今后一段时期将继续以热力采油为主要开发方式,而蒸汽驱依然是区块最重要的上产措施。目前,仅在洼38块东三段采用蒸汽驱开发。结合前期先导试验取得的成果,考虑继续扩大蒸汽驱范围。本文主要针对洼38块外扩的3个蒸汽驱井组实际特征,深入刻画地质体,开展油藏数值模拟研究,优化蒸汽驱操作参数。提高蒸汽驱扩大方案的增产效果,确保油田产量规模。

The reservoir numerical simulation study of steam flooding extended well groups in Wa-38 block
Abstract:Wa-38 heavy oil reservoir is the main block of Liaohe Xiaowa oilfield. By 2018, the block has been continuously developed for 27 years, mainly through steam stimulation and steam flooding. Combined with the development effect and comprehensive benefits, thermal oil recovery will continue to be the main development mode of Wa-38 block in the future period, and steam flooding is still the most important production measure. At present, steam flooding has been only used in the third section of Dongying group of Wa-38 block. Combined with the results of previous pilot test, the scope of steam flooding is considered to be extended. This paper based on the actual characteristics of the three steam flooding well groups with the expansion of Wa-38 block, further depicting the geologic body, carrying out the study of reservoir numerical simulation, and optimizing the operating parameters of steam flooding. Trying to improving the production increase effect of the steam flooding expansion scheme, ensuring oil field production scale.
