辽河稠油油藏火驱辅助重力泄油技术探索及实践

为了改善辽河油田稠油的开发效果,以S块大凌河油藏为研究对象,分析了应用火驱辅助重力泄油开发稠油的技术可行性,运用物模、数模和油藏工程等方法对开发参数进行了优化设计,根据设计结果,部署了试验井组5个,目前第1个火驱辅助重力泄油先导试验井组已成功点火,并见到初步效果。

Combustion assisted gravity drainage technology exploration and practice of Liaohe heavy oil reservoirs

In order to improve heavy oil development effects of Liaohe oilfield,based on S block of Dalinghe oil reservoir,the technical feasibility of the combustion assisted gravity drainage has been analyzed.By using physical model,numerical model,reservoir engineering methods and etc,the develop parameters have been designed and optimized.According to the design results,5 test well groups have been deployed.At present,the first well group with combustion assisted gravity drainage has been successfully ignited and has achieved preliminary effects.
