Abstract

Abstract

In order to reveal the distribution pattern of the Archaeozoic buried hill reservoirs in the Bozhong 19-6 condensate field, integrated study is carried out with cores, well logs, well testing data, seismic data in addition to outcrops. The Archaeozoic buried hill reservoir consists of weathered crust reservoirs and internal rock reservoirs, which have obvious differences in controlling factors and distribution patterns. The formation of weathered crust reservoir mainly depends upon structural deformation and weathering, of which the thickness is dependent on the ancient landform. It usually becomes thinner from the paleosrtuctural high to the structural low. Rock types, local faults, microreliefs and topographic slopes are also the controlling factors needed to be considered. However, the inner part reservoir is mainly controlled by the high-angle faults, and the main reservoir space is provided by structural fractures.
