摘　　要：通过分析中国石化稠油油藏未开发储量动用情况,总结出主要油藏类型的开发技术应用现状及动用条件,并开展基于开发技术适应性的油藏分类评价,把未开发稠油油藏技术需求分为三大类:①现有开发技术可以动用的薄互层普通稠油和浅薄层特/超稠油两类油藏,但经济效益较差;②需要进一步开展技术攻关试验的特深层低渗透稠油、强敏感稠油、强边底水稠油以及超浅层超稠油油藏;③攻关难度较大、难以动用的油藏类型为超深层低渗透稠油油藏、极强敏感稠油油藏、水油体积比大于9的强边底水稠油油藏以及薄层底水稠油油藏。By analyzing the utilization of undeveloped reserves in Sinopec heavy oil reservoirs,the current application status and utilization conditions of development technologies for major reservoir types are summarized,and then the reservoir classification evaluation based on the adaptability of development technologies is carried out.The technical requirements for undeveloped heavy oil reservoirs are divided into three categories.①The existing development technology can utilize two types of reservoirs:thin interbedded ordinary heavy oil and shallow thin layer extra/ultra-heavy oil,but the economic benefits are poor.②It is necessary to further carry out technical breakthrough tests for ultra-deep low-permeability heavy oil,strong sensitive heavy oil,strong edge and bottom water heavy oil and ultra-shallow ultra-heavy oil reservoirs.③The types of reservoirs that are difficult to tackle and difficult to develop include ultra-deep low permeability heavy oil reservoirs,highly sensitive heavy oil reservoirs,strong edge and bottom water heavy oil reservoirs with a water oil volume ratio greater than 9,and thin layer and bottom water heavy oil reservoirs.
