摘要: 辽东凹陷东南缘古近系沙二段发育砂砾岩沉积。利用井壁取心、薄片鉴定、元素分析等资料,从母岩性质、沉积特征以及成岩作用等方面对辽东凹陷东南缘古近系沙二段砂砾岩储层特征及控制因素进行了分析。研究结果表明:①研究区砂砾岩储层孔隙度为3.5%~19.0%,平均值为10.1%;渗透率为0.9~120.6 mD,平均值为39.8 mD,整体表现为低孔低渗特征,自北向南物性逐渐变好;②裂缝发育的砂砾岩为研究区的优质储层,其母岩为变质石英岩,远源辫状河三角洲同向断阶坡折带的下部发育成分成熟度较高的优质储层,泥质收缩缝及溶蚀作用对研究区南段储层物性具有改善作用,碳酸盐胶结对研究区北段储层物性具有破坏作用;③缓坡带同向断阶坡折带有利于形成裂缝继承型砂砾岩储层,近岸古地貌局部高点易形成混积滩型优质储层,为下一步岩性油气藏勘探的潜力区。

Abstract: Sandy conglomerate is developed in the second member of Paleogene Shahejie Formation(E2s2)in the southeastern margin of Liaodong Sag. Based on the data of sidewall coring,thin section identification and element analysis,the reservoir characteristics and controlling factors of sandy conglomerate of E2s2 in southeastern margin of Liaodong Sag were analyzed from the aspects of parent rock properties,sedimentary characteristics and diagenesis. The results show that:(1)The porosity of sandy conglomerate reservoirs in the study area ranges from 3.5% to 19.0%,with an average of 10.1%,and the permeability is 0.9-120.6 mD,with an average of 39.8 mD. The overall physical properties are characterized by low porosity and low permeability,and gradually improve from north to south.(2)The sandy conglomerate with fracture developed is a high-quality reservoir in the study area,and its parent rock is metamorphic quartzite. High-quality reservoirs with high composition maturity are developed in the lower part of concordant fault slop-break zone of distal braided river delta. Argillaceous shrinkage fractures and dissolution can improve the physical properties of the reservoirs in the south section of the study area,and carbonate cementation is destructive to the physical properties of the reservoirs in the north section of the study area.(3)The concordant fault slop-break zone in gentle slope zone is conducive to the formation of inherited fracture sandy conglomerate reservoirs,and the local high parts of nearshore ancient landform are easy to form mixed beach high-quality reservoirs, both of which are potential areas for next lithologic reservoir exploration.

Key words: sandy conglomerate, low porosity and low permeability, fractures, gentle slope zone, lithologic reservoir, the second member of Shahejie Formation, Paleogene, Liaodong Sag
