一种新的蒸汽吞吐稠油油藏证实储量计算方法

A new proved reserves calculation method of the steam stimulation in heavy oil reservoir

以辽河油区蒸汽吞吐稠油生产数据为基础,在研究其累积注汽量与累积产油量之比(累积汽油比)与累积产油量关系的基础上,提出了一种适合蒸汽吞吐稠油油藏证实储量计算的新方法,并以曙光油田杜229块为例,其计算结果与SEC储量评估方法计算结果对比,相对误差为2.36%,符合石油行业标准。证实了该方法的适用性和可行性,对其他油田有一定的借鉴意义。

Based on the production data of the steam stimulation in heavy oil reservoir in Liaohe oildom and the relations of the ra- tio of cumulative injeetied steam and cumulative oil production （cumulative oil ratio） and cumulative oil production, this paper pro- posed a new proved reserves calculation method which is suitable for the steam stimulation in heavy oil reservoir. Taking block Du- 229 in Shuguang oilfield as an example, compared its computed result with that of SEC reserve estimation method, the relative error was 2.36 % and kept with oil industry standard. It is proved that this method is applicable and feasible to provide reference to other oil fields.
