江汉油田未动用储量分类评价实践

Classification evaluation of non-producing reserves in Jianghan oilfield

江汉油田未动用储量评价工作是老区持续稳产的重要组成,整个江汉油田的未动用储量分布在三个油区,占已探明储量的20%左右。未动用储量的特点是平面上分布零散,层系上分布较集中,油藏类型以稠油油藏和低渗透油藏为主,主要从地质和工艺两方面开展评价工作。

The evaluation of non-producing reserves in Jianghan Oilfield is an important portion of the continuous and stable production in the old area.The non-producing reserves in Jianghan oilfield as a whole are distributed in three oil areas,accounting for about 20%of the proven reserves.The non-producing reserves are scattered horizontally and concentrated vertically.The reservoir types are mainly heavy oil reservoirs and low permeability reservoirs.The evaluation is mainly carried out from the geological and technological aspects.
