摘要
对稠油油藏而言,注蒸汽热采已成为勘探阶段的主要试油方式和开发阶段的主要生产方式,准噶尔盆地通过注蒸汽开采的稠油已占年度石油总产量的1/3以上。通过剖析准噶尔盆地已投入开发的部分典型稠油油藏,研究探讨稠油油藏的经济极限油汽比(储量起算标准)、初步建立了不同埋深、不同开采方式、不同油价的工业油汽比标准,在稠油油藏储量计算中得到成功应用。
For Heavy Oil Reservoir,thermal recovery by steam injection is the main testing method and mode of production during development stage,and more than one third of annual oil total output is the steam injection recovery in Junggar Basin.Through analysis of some typical heavy oil reservoirs of Junggar Basin that have just been exploited,ratio of the economic limit oil-steam of heavy oil reservoir(indicator of reserves estimation),the standard of industrial oil-steam ratio of different buried depth,recovery method and oil price have been preliminarily established,and have been successfully used in reserve calculation of heavy oil reservoir,which also has important significance for assessment of heavy oil reservoir.
