川南地区五峰组-龙马溪组黑色页岩储层特征
Characteristics of black shale reservoir of Wufeng-Longmaxi Formation in the Southern Sichuan Basin
摘要
Abstract
Using a series of analyses including core observation,conventional polarization microscope,X-ray diffraction,SEM,and well log,this research studied the mineral composition,organic geochemical features,storage space,physical property and gas-bearing,and categorized the black shale in the study area.The key factors that affect shale gas reservoirs were analyzed,and the favorable area was recognized.The results show that fourteen lithofacies are identified based on our classification.The black shale has a high total organic matter content and high maturity.With a high free gas content,the siliceous shale has the best physical properties and gas-bearing;the next is the mixed shale,and thc calcareous shale has the least favorable physical properties and gas-bearing,in which almost no free gas is contained.Free gas is the main factor that affects the total gas content.SEM observations show that interparticle pore mainly develops along quartz in the siliceous shale;and the development of interparticle pore is the key factor that lead siliceous shale to be the best shale reservoirs with better physical property,gas-bearing and high free gas content.In the study area,TOC and lithofacies are the major factors affecting the shale gas reservoir.The transitioning area mainly develops siliceous shale,the total thickness of type Ⅰ and type Ⅱ reservoirs can reach 44.7 m,which is the most favorable exploration region.关键词
