摘要

利用高压压汞技术对页岩油储集层微观孔喉进行表征,并在此基础上建立页岩油储集层分级评价标准及成储下限,建立基于测井资料进行页岩油流动单元划分的新方法。依据进汞曲线的拐点及分形特征,提出了适合于页岩油储集层的分类新方案:微孔喉(小于25 nm)、小孔喉(25~100 nm)、中孔喉(100~1 000 nm)、大孔喉(大于1 000 nm),进一步按照页岩所含不同类型微观孔喉的数量将其分为Ⅰ级、Ⅱ级、Ⅲ级和Ⅳ级储集层,分级点对应的孔喉平均半径分别为150,70,10 nm。利用渗透率与孔喉半径的相关关系,建立了储集层分级评价的渗透率标准门槛分别为1.00×10-3,0.40×10-3,0.05×10-3 μm2。利用同一水力流动单元内孔隙度、渗透率良好的指数关系,构建了由测井资料评价储集层流动带指数、划分页岩油流动单元的新方法。在东营凹陷的应用表明,所建立的标准可以应用于页岩油储集层的分级评价。图7表3参27

Abstract

On the basis of the characterization of microscopic pore-throats in shale oil reservoirs by high-pressure mercury intrusion technique, a grading evaluation standard of shale oil reservoirs and a lower limit for reservoir formation were established. Simultaneously, a new method for the classification of shale oil flow units based on logging data was established. A new classification scheme for shale oil reservoirs was proposed according to the inflection points and fractal features of mercury injection curves: microscopic pore-throats (less than 25 nm), small pore-throats (25-100 nm), medium pore-throats (100-1 000 nm) and big pore-throats (greater than 1 000 nm). Correspondingly, the shale reservoirs are divided into four classes, Ⅰ,Ⅱ, Ⅲ and Ⅳ according to the number of microscopic pores they contain, and the average pore-throat radii corresponding to the dividing points are 150 nm, 70 nm and 10 nm respectively. By using the correlation between permeability and pore-throat radius, the permeability thresholds for the reservoir classification are determined at 1.00× 10-3 μm2, 0.40×10-3 μm2 and 0.05×10-3 μm2 respectively. By using the exponential relationship between porosity and permeability of the same hydrodynamic flow unit, a new method was set up to evaluate the reservoir flow belt index and to identify shale oil flow units with logging data. The application in the Dongying sag shows that the standard proposed is suitable for grading evaluation of shale oil reservoirs.
