鸭儿峡油田L油藏难采区储集层特征

针对鸭儿峡油田L油藏难采区储集层的特点,在分析难采区构造形态、沉积特征、试油、试采效果的基础上,采用砂岩储集层的常规研究手段,通过对该区测井资料进行二次解释,建立了储集层的分类、有效层划分标准，表述了储集层非均质性，对储集层的孔隙度、渗透率、原始含油饱和度和有效厚度、储集层的敏感性进行了定量描述,为难采区的有效开发提供了依据。

Reservoir Characteristics of Difficult-to-Produce Area in L Oil Pool,Ya'erxia Oilfield

In view of reservoir feature in difficult-to-produce area of L oil pool in Ya 'erxia oilfield, this paper analyzes the structural style,sedimentary character,formation testing and production test fects, based on which establishes standards for reservoir classification andnet pay thickness recognition, describes the reservoir heterogeneity, and quantitatively determines the porosity, permeability, initial oilsaturation, net pay thickness and reservoir sensitivity, by using conventional study method for sandstone reservoir and re-interpretation ofwell test data. The sound bases could be as a guide for effective development of this dfficult-to-produce area.
