Abstract

Abstract

Founding lithologic reservoir is of greater potential as the exploration changing from the structural reservoir into the lithologic reservoir, while the reservoir analysis is the focus of the lithologic reservoir exploration.In the Liangjia area, Yitong basin, drilling shows that most of oil & gas reservoirs lie in the Sheling Formation, which belong to the fan delta facies deposited jointly by two provenances.A new method is needed to analyze this fan delta detail and its control on the reservoir because of the big space of wells in the study area.In this paper, a new analysis method and idea on the fan delta deposited jointly is presented on the basis of the interpretation of the sandstone in the impedance cube and the shape of the different layers of sandstone created on the map, then the details of fan delta are analyzed.Three major findings are as follows: (1) Fan deltas of four periods are identified in the Sheling Formation, expanding gradually in the area; (2) The fan deltas were deposited jointly by the two provenances, which controlled different layers of sandstone; (3) The application of impedance cube offers a new approach to interpret, analyze the different layers of sandstone, and to identify the fan delta facies.
