在系统收集和整理下寺湾泉54区块长2储层资料的基础上,利用大量的分析化验资料,通过对储层沉积特征、岩石学特征、物性特征、孔喉特征、生储盖特征、油藏特征及成藏主控因素的分析,表明该区块属于三角洲前缘亚相沉积,储层具低孔特低渗特点;具有良好的生储盖组合,油气成藏主要受沉积微相和鼻隆构造或构造相对高部位控制。
Based on the systematic collection and collation of Chang2 reservoir data of Block Siwanquan 54, a large amount of analytical laboratory data are used to analyze the characteristics of reservoir sedimentary, petrological, physical, pore-throat, , Reservoir characteristics and main controlling factors of hydrocarbon accumulation indicate that the block belongs to the delta front sedimentary facies and the reservoirs have the characteristics of low porosity and low permeability. It has a good reservoir-cap assemblage and hydrocarbon accumulation is mainly caused by sedimentary micro Phase and Nose Long structure or structure of relatively high parts of the control.
