大庆F油层岩石矿物含量对速敏的影响

Effect of Rock Mineral Content on Velocity Sensitivity in Daqing F Reservoir

F油层是大庆外围油田现阶段主力产油层之一,研究它的矿物含量对速敏的影响对高效开发该油层有很高的指导意义。使用X射线衍射、铸体薄片和偏光显微镜分析得出F油层天然岩心的各种矿物含量。通过速敏实验,得到岩心的速敏指数。在多种矿物影响下,使用SPSS分析软件确定多种矿物含量在控制变量下的相关性,得出F油层速敏的主控矿物,分析得出主控矿物与速敏指数之间的关系,拟合出一个矿物含量与速敏之间的数学模型,为高效开发该储层油气资源提供保证,并为速敏研究提出一种新的认识。

The F oil reservoir is one of the main oil producers in Daqing peripheral oilfield at present,so it is of great significance to study the influence of its mineral content on velocity sensitivity for efficient development of the F reservoir.Using X-ray diffraction,casting thin section,and polarizing microscope analysis,the mineral content of natural cores in the reservoir was obtained.Through the velocity sensitivity experiment,the velocity sensitive index of the cores was acquired.Under the influence of various minerals,SPSS analysis software was used to determine the correlation of various mineral contents under the control variables,the key controller minerals of the reservoir velocity sensitivity and their relationship with velocity sensitivity index were determined,and a mathematical model between mineral content and velocity sensitivity was fitted,which provides guarantee for the efficient development of oil and gas resources in the reservoir,and puts forward a new understanding for velocity sensitivity research.
