摘要
江汉油区盐间非砂岩储层结构类型多,主要有孔隙型、孔隙-裂缝型和裂缝型;粘土矿物含量较高;这种储层主要是泥岩,含盐和白云石,裂缝发育,并且岩性变化大。决定盐间非砂岩储层敏感性相当复杂。本文结合多种室内分析资料和开发试验技术,对盐间非砂岩储层的敏感性进行了综合评价,指出各种敏感性对储层的影响程度和影响机理,为盐间非砂岩油层进行增产措施提供试验研究依据。
There are various reservoir structure types of the insert salt layers non-sandstone reservoirs in Jianghan Oil Region,mainly including porous type,porous-fracture type and fracture type,and high mineral contents of clay. These reservoirs are mainly contained mudstone,with salts and dolomite,fracture growth,and variational reservoir lithology,which determine reservoir sensitivities are very complicated. Combined with various laboratory analysis data and development and experiment technology, this paper has evaluated synthetically the sensitivities of the insert salt layers non-sandstone reservoirs and indicated the influence degree and mechanism of various sensitivities on reservoir,and provided experiment and investigation bases of stimulation for increasing oil production.
