 就稠油热采储层精细油藏描述的技术现状看：国外已经形成了完整的研究方法和技术体系，特别是在利用地震技术对油藏开发过程监测及剩余油分布规律的精细刻画等方面，具有相当高的研究水平；国内在储层单砂体的精细刻画、隔夹层研究以及储层在热采过程中的变化规律等方面，进行了大量的研究工作，取得了一定进步。稠油热采储层研究的关键问题为地层精细划分与对比、沉积微相研究、隔夹层发育规律描述、储层综合分类评价和地质建模研究等。在此基础上认为，稠油热采储层精细油藏描述研究的主要发展方向为井震结合断裂系统的精细刻画、地质体分类评价、稠油热采储层变化规律研究、剩余油分布规律的四维地震监测和隔夹层封隔能力的物理模拟与数值模拟验证等五大方面。

 Based on the current research status of fine reservoir description of the thermal recovery heavy oil reservoir, it is indicated that complete research methods and technique systems have formed abroad, among them the reservoir development process monitoring and fine characterization of remaining oil distribution with seismic technology have reached a high level; meanwhile the domestic researchers have done a lot of jobs and made certain progress on single body sand fine description, interlayer insulation and reservoir change rules in the thermal recovery process, etc. Based on the authors′ research experiences, it is believed that the main difficulties of the research of thermal recovery of heavy oil reservoirs are fine stratigraphic division and correlation, sedimentary microfacies study, interlayer insulation development rule description, reservoir classification evaluation, and integrated geological modeling research. Based on the formation above, the key research development directions of fine reservoir description of thermal recovery of heavy oil are fine description of fracture systems based on well-seismic data, classification evaluation of geological bodies, the reservoir change law of heavy oil thermal recovery, 4D seismic monitoring of remaining oil distribution law, and physical simulation and numerical simulation of interlayer insulation packer ability.
