- 摘要:
- 为解决稠油热开采中存在的蒸汽波及效率低、储层能量匮乏等难题，文中研究了多介质暂堵增能技术在高轮次稠油热采中的应用。在注入颗粒暂堵剂、凝胶暂堵剂、瓦斯增能剂的基础上，对高渗透通道进行高效封闭，提高蒸汽波及范围，并为储层提供能量，增强其可流动性。经现场应用和油藏动态监测数据分析，证明了该工艺在提高注汽吞吐能力、降水增产等方面有显著效果。研究成果表明，利用多介质暂堵增能技术可以实现高循环吞吐稠油油藏的高效开发，具有良好应用前景。
In order to solve the problems of low steam sweep efficiency and lack of reservoir energy in heavy oil thermal recovery,this paper studies the application of multi-media temporary plugging and energy enhancement technology in high round heavy oilthermal recovery. On the basis of injecting particle temporary plugging agent, gel temporary plugging agent and gas energyenhancer, the high permeability channel is effectively sealed to improve the steam sweep range, provide energy for the reservoir andenhance its fluidity. Through on-site application and analysis of reservoir dynamic monitoring data, it has been proven that thisprocess has significant effects in improving steam injection throughput capacity, reducing precipitation and increasing production.The research results indicate that the use of multi-media temporary plugging and energy enhancement technology can achieveefficient development of high cycle heavy oil reservoirs, which has good application prospects.
