【摘要】：苏里格气田开发已全面进入稳产阶段,后备优质储量资源相对不足,对低于物性下限标准的储层进行潜力储层筛选并评价其开发可动用性,具有重要意义。面对气田致密砂岩储层分类不尽完善的问题,继承性开评展了储层系统性综合评价,将储层划分成5大类6种类型,并明确Ⅲ2类储层是未来最具有开发潜力的储层类型。潜力储层形成主控于同砂岩粒度密切相关的储层物性,即发育于高能心滩-辫状河道微相中上部、中-低能心滩-辫状河道微相主体及中下部物性较差的中-细粒岩相部分。总结了潜力储层的6种发育模式,提出了间接动用、组合动用和直接动用等3种开发动用方式。可动用性评价表明,直接和间接动用方式开发效果相对较好,潜力储层具备较好的开发前景。潜力储层特征及可动用性评价可为未来此类储层开发提供有力支撑。
[Abstract]:The development of Sulige gas field has entered the stage of stable production, and the reserve quality reserves are relatively insufficient. The reservoir below the lower limit of physical properties is screened for potential reservoirs and its development availability is evaluated. Facing the problem that the classification of tight sandstone reservoir in gas field is not perfect, the inheritance evaluation develops the comprehensive evaluation of reservoir system and divides the reservoir into 5 categories and 6 types. It is also clear that type 鈪，
