Abstract

Abstract

With the increasing exploration degree of shallow formations (mainly Meogene) in offshore China, middle⁃deep buried formations (mainly Paleogene), especially the Eocene and Oligocene, is one of the important exploration targets in the future. However, there is still a lack of systematic research on the characteristics and dissolution of the middle⁃deep clastic reservoirs in offshore China. In this paper, Liaozhong sag, Xihu sag and Baiyun sag were taken as target areas. Based on a large number of new drilling, physical property data and various tests, the petrological characteristics, physical property and pore types of paleogene clastic reservoirs in offshore China were systematically elucidated, and their dissolution regularities were analyzed and summarized. The results show that the Paleogene sandstone reservoirs in offshore China were mainly composed of feldspar⁃lithic sandstone or lithic⁃feldspar sandstone. Different structures and lithology varied significantly in the same sag, and the content of quartz and lithic varied slightly in different layers. The reservoir was mainly medium⁃low porosity and low permeability, and medium⁃high porosity and permeability reservoirs are mainly developed in the first and second member of Shahejie Formation and the upper member of Zhuhai Formation of Baiyun Sag. The primary pores only developed in the north of Pinghu slope in Xihu Sag, the fourth member of Shahejie Formation in Liaozhong Sag and the upper member of Zhuhai Formation in Baiyun Sag. The dissolution of feldspar, calcite and part of fragments was mainly by acidic fluid. The dissolution in Liaozhong Sag varied markedly between different formations, with significant dissolution in sandstone reservoirs controlled by shallow⁃buried deep volcanic host rocks and medium⁃deep rigid host rocks, while the West Slope of the Xihu Sag showed early succession calcite dissolution in a section of the Pinghu Formation and three sections of the Pinghu Formation, and the Baiyun Sag dissolution was mainly kaolinization of feldspar and illite lithification of kaolinite.This study aims to provide reference for exploration and development of paleogene clastic reservoirs in offshore China.
