多元热流体吞吐技术在海上稠油油藏开发中的应用

摘要

Seventy percent of offshore oil has been discovered in China is heavy oil. The heavy oil's viscosity is high, mobility is poor. With the use of conventional development methods, the well productivity is low, oil production rate is small and recovery is low. In or- der to obtain more oil, putting offshore heavy oil to use sufficiently and effectively is becom- ing more and more important. Complex thermal fluid huff and puff technology is a new tech- nology of developing offshore heavy oil in recent years, with significant stimulation and good application effect. With the constant development of complex thermal fluid huff and puff technology, it will be large-scale used in offshore heavy oil reservoir development and ex-ploration well testing. And it can make a significant contribution to China's offshore oil field development, and provide energy security for China's sustainable development.%中国海上已发现原油储量中稠油占70％，稠油粘度高、流动性差，采用常规开发方式油井产能低，采油速度小，采收率低。为了获得更多的石油，将海上稠油、特稠油充分、有效的动用起来，显的越来越重要。多元热流体吞吐技术是近几年来开发海上稠油油藏的新技术，增产效果明显，取得了良好的应用效果。随着多元热流体吞吐技术的不断发展，将大规模应用于海上稠油油藏开发以及海上稠油探井测试，可为我国海上油田开发做出重大贡献，为我国可持续发展提供能源保障。
