RESERVOIR CHARACTERISTICS AND EVALUATION OF DENGLOUKU FORMATION IN CHANGLING-1 GASFIELD
摘要
Abstract
Changling-1 Gasfield is located in Harjin Structural Belt of the middle uplift of Changling Fault Depres sion of South Songliao Basin. The reservoir characteristics of Denglouku Formation are analyzed from the aspects of the petrology, AS type, pore textures, physical properties and so on in this gasfield. In addition, the reservoir are classified by means of fuzzy clustering method, and the distributions of each reservoir are determined with the help of comprehensive adoption of multi-attribute matching and modeling method. The study shows that reservoir litholog ic types are mainly characterized by feldspathic litharenite and lithic arkose with high content of unstable minerals, medium-maturity of textures and low-maturity of compositions; types of AS are complex and diverse and mainly fea tured by secondary intergramilar and intragranular dissolved pores; The AS is small and low-connectivity and strong heterogeneity, belonging to low-porosity and low-permeability reservoirs. The classification and evaluation of the reservoirs results show that No. I and II-class reservoirs are well-developed and pretty thicker in Harjin Structural Peak Zone of the middle operational area taking Chang Deep 1 -1 Well and other 4 wells as boundary. These reser voirs are the favorable regions for future exploration and development.关键词
