辽河油区以稠油为主，在SEC 储量评估方法中，尚未提及蒸汽吞吐稠油油藏的储量评估方法。因 此，在该区提出了一种基于累积产油量与累积注汽量来求取证实储量的新方法，同时引入了蒸汽吞吐稠 油油藏的注汽量和产油量2 个重要参数，并以辽河油区杜229 区块为例，证实了该方法的适用性和可行 性，对其他同类型油田提供了一定的借鉴作用。

Liaohe oil province is mainly of heavy oil. In the SEC reserves evaluation method, it has not mentioned the reserves evaluation method of steam huff and puff in heavy oil reservoir. This paper proposed a new method based on the cumulative oil production and cumulative steam injection volume to obtain the proved reserves. This method introduces steam injection volume and oil production of the steam huff and puff in heavy oil reservoir. Taking Du 229 block in Liaohe oil province as an example, the calculation result proves the applicability and practicability of this method, which can provide reference for other fields.
