基于流动单元用多参数方法预测火山岩渗透率
Volcanic Reservoirs Permeability Prediction Using Multi-parameter Approach Based on Hydraulic Flow Units
摘要
Abstract
Fast changes of the volcanic reservoirs lithology,varieties of mineral components,development of fractures and dissolution pores,complexity of pore structures and strong non-homogeneity lead to the great difficulties in the volcanic reservoirs quantitative evaluation.We use core data of several wells in the same area to divide hydraulic flow units (HFU) of the formation,and establish the permeability model for each HFU by cluster analysis method.In the uncored wells,we establish regression relationship of hydraulic flow index (IFz) with several logging parameters to find the discriminant function for the division of HFU.We determine the effective porosity of the volcanic reservoirs by density-NMR porosity method.And then we verify this method with volcanic reservoir data in Changling,Yingtai fault depression of southern Songliao basin,the result of which is much better.关键词
