Sedimentary Facies Identification by Fuzzy Pattern,
Liao Mingguang, Zhou Nanxiang & Tan Dehui
Log facies analysis is a significant aspect of modern reservoir description. Because of sedimentary microfacies, an attempt was made at quantified analysis of sedimentary microfacies by fuzzy pattern and satisfactory result is obtained. An example shows how to use Pinluo Well No.1 in Sichuan Pinluoba Gas Field as a key well to identify the sedimentary microfacies of single - well profile in Pinluo Well N o. 2 by fuzzy pattern. Its result conforms to that of geological analysis.
