海上稠油油藏多元热流体吞吐开采技术优化研究

Research on optimized multiple thermal fluids stimulation of offshore heavy oil reservoirs

针对我国渤海A油田稠油油藏原油粘度高、冷采效果差的问题,在分析多元热流体吞吐开采机理的基础上,开展了多元热流体吞吐数值模拟研究,对多元热流体吞吐参数进行了优化,并针对该油田进行开发井网部署,制定多元热流体吞吐整体开发方案,预测开发效果。现场先导试验表明:对稠油油藏进行多元热流体吞吐开发,可以有效提高油井产能,改善开发效果,对海上稠油油藏开发模式的转变具有重要的指导意义。

Heavy oil reservoir in Bohai A oilfield has the characteristics of high viscosity and poor efficiency of cold production. Based on the analysis of multiple thermal fluids stimulation, numerical simulation of it has been carried out and the parameters have been optimized. Aiming at the deployment of development well pattern, the whole FDP has been established which can make a prediction of the development effect. The field pilot testing indicates the optimized multiple thermal fluids stimulation can efficiently improve oil well productivity and therefore provides guidance for development modes change of offshore heavy oil reservoirs.
