【摘要】：通过采用岩心观察、薄片鉴定、扫描电镜观察、压汞实验等技术手段,利用储层特征定性描述与成岩改造孔隙量定量表征相结合的研究方法,对红层储层沉积成岩特征和储集空间成因类型进行研究,明确红层储层物性的主控因素。结果表明:红层沉积时期发育冲积扇—洪水-漫湖—盐湖沉积体系;储层主要发育在冲积扇、漫湖坪、漫湖席状砂、漫湖滩坝中,储层中主要发育原生粒间孔、残余粒间孔、粒间溶孔、粒内溶孔等4类孔隙;红层储层受控于沉积作用和成岩作用,其中沉积作用表现为岩石粒径和成熟度对储层孔隙结构和物性的影响,而成岩作用对储层物性起到明显的控制作用,压实减孔量主要受控于深度和填隙物含量控制,胶结减孔量受控于早期碱性成岩环境的强弱,溶蚀增孔量受控于中晚期酸性成岩环境的强弱,离湖盆中心越近,胶结减孔量、溶蚀增孔量越高,反之则越低。
[Abstract]:By means of core observation, thin section identification, scanning electron microscope, mercury injection experiment technique, the reservoir characteristics of qualitative and quantitative research methods to characterize rock pore volume transformation combination, the red layer reservoir sedimentary characteristics and reservoir space types are studied, the main control reservoir clear red factor of reservoir property. The results show that the alluvial fan and flood Lake - Saline Lake sedimentary system of red sedimentary period; the main reservoirs in the alluvial fan, over Lake Ping, over Lake sand sheet, diffuse lake dam, the reservoir mainly developed primary intergranular pores, residual intergranular pores. Intergranular dissolution pores, intragranular dissolved pores and other 4 types of pore; red reservoir controlled by sedimentation and diagenesis, the sedimentary rock is the size and maturity of reservoir pore structure and physical properties of the influence of diagenesis to control effect on Reservoir since the reduction of hole compaction The amount is controlled by the depth and filler content control, cement porosity reduction is controlled by the early alkaline diagenetic environment is weak, increasing of pore volume is controlled by dissolution in late acidic diagenetic environment is weak, from the center of the basin near the cement porosity reduction, dissolution pore increasing Liangyue high, and vice versa.
