松辽盆地双城地区登娄库组储层特征及控制因素
|
摘要
为深化松辽盆地登娄库组储层特征及发育主控因素认识,以沉积相带研究为基础,利用双城地区登娄库组的岩心、薄片鉴定、电镜扫描、粒度分析及流体包裹体分析等方法,深入分析储层的沉积学、岩石学特征,并结合地史分析,探讨双城地区登娄库组储层的储集空间类型及演化规律。研究结果表明:储层孔隙度为15%～20%,渗透率一般为(10～500)×10~(-3)μm~2,储层岩性以长石砂岩和岩屑长石砂岩为主,分选中等,储集条件较好;登娄库组经历了冲积扇到三角洲的沉积充填序列,储集层主要发育在三角洲河道砂体内,渗透率与体积分数具有明显的负相关性;储层空间主要以原生孔隙为主,随着青山口组末期区内烃类的大量注入,形成大量的次生溶孔,有效改造了储层空间。研究成果可为下步双城地区的井位部署及松辽盆地深层勘探提供理论依据。
In order to deepen the understandings of the reservoir characteristics and main controlling factors of Denglouku Formation in Songliao Basin, based on the research on the sedimentary facies belt, with the help of the methods including core observation, thin section identification, scanning electron microscope, grain size and fluid inclusion analyses etc, the reservoir sedimentology and petrology characteristics were deeply figured out, and moreover combined with the geohistory analysis, the types of the reservoir accumulation space and the evolution regularity were discussed. The study results show that the porosity of the reservoir is from 15% to 20%, the permeability is generally(10-500)×10~(-3)μm~2, the lithology of the reservoir is dominated by feldspar sandstone and lithoclastic feldspar sandstone, which are moderately sorted and the accumulating conditions are pretty better; Denglouku Formation has experienced the alluvial fan and delta sedimentary sequence, the reservoirs are mainly developed in the delta channel sandbodies, the permeability and shale content have significant negative correlation; reservoir accumulating space is mainly composed of primary pore, as a large amount of the hydrocarbon injected into the reservoir at the end of Qingshankou Formation, a large number of the secondary solution pores were developed, thus the accumulating space was effectively transformed. The study results can provide the theoretical evidences for the well location arrangement in Shuangcheng area and furthermore the exploration of the deep layers in Songliao Basin in the next step.
