A kind of practical effective thickness interpretation and evaluation method for glutenite reservoirs

Discrimination mode for effective thickness interpretation division of glutenite reservoirs with large differences between lithology and physical property is not simply based on criterions of siltstone reservoirs with similar lithology and physical property to use.Thus,aiming at geologic characteristics of glutenite reservoir in Nantun Formation of Huhenuoren oilfield of Hailaer Basin,various factors of influenced glutenite reservoirs containing oil property are analyzed,log response curve is reasonably optimized,and then standard plate of effective thickness electronic division of reservoir including several parameters,such as deep direction finding,lithologic denisity,acoustic travel time and micro-spherically focusing is developed.This plate breaks through traditional individual reservoir limitation interpretation mode and obviously advances accuracy.Meanwhile,according to reservoir two divisions which are better effective layers and worse effective layers,it provides a basis for reservoir description and production evaluation.
