稠油油藏蒸汽吞吐注入能力影响因素研究

蒸汽吞吐作稠油油藏开发的主力技术，为稠油开发作出了巨大的贡献，但是目前对于蒸汽吞吐稠油油藏注汽能力影响因素以及各个因素影响程度的研究还不充分。为防止汽窜、 超覆等，提高蒸汽的热利用率，通过室内实验，在考虑油藏渗透率、注汽速度、注汽温度以及原油黏度的情况下，研究了蒸汽吞吐稠油油藏的吸汽规律，基于均一化研究，分析了上述影响因素对吸汽能力的影响程度，明确了不同注采参数的影响规律，为油田稠油油藏蒸汽吞吐开发方案制定提供指导。

Research on influencing factors of steam huff and puff injection capacity in heavy oil reservoir steam

Steam huff and puff is the main technology for the development of heavy oil reservoirs and has made a great contribution to the development of heavy oil.However，the current research on the factors affecting the steam injection capacity of steam huff and puff heavy oil reservoirs and the degree of influence of each factor is insufficient.In order to prevent steam channeling，overriding，etc.，and to improve the heat utilization rate of steam，through laboratory experiments，considering the reservoir permeability，steam injection rate，steam injection temperature and crude oil viscosity，the steam stimulation of heavy oil reservoirs was studied.Steam absorption law，based on homogenization research，the degree of influence of the above-mentioned influencing factors on steam absorption capacity was analyzed，the influence law of different injection-production parameters was also clarified，whch has provided guidance for the formulation of steam stimulation development plans for heavy oil reservoirs.
