华池油田华152井区长_3~3砂组沉积微相研究

SEDIMENTARY MICROFACIES STUDY OF CHANG_3~3 SAND GROUPIN HUA-152 WELL BLOCK IN HUACHI OILFIELD

通过对华池油田华152井区10口井岩心的观察和对200多口井单井沉积相、剖面相、平面相的分析研究,查明该区长33砂组为一套曲流河三角洲沉积,可见到曲流河三角洲前缘和前三角洲两个亚相,从中还识别出了水下分流河道、支流间湾、河口砂坝、远砂坝和前三角洲泥等5个微相。

In H-152 well block in Huachi Oilfield, there were drilling cores of 10 wells been detailed observed and single well sedimentary facieses, profile facieses and plane facieses of over 200 wells been analyzed. It was held that the Chang^3_3 sand group is a suit of meandering stream's delta deposition system. And two subfacies including meandering stream's delta front and prodelta could be found. And its sedimentary microfacies were also deep studied.
