Abstract

Abstract: The deep clastic rocks of Triassic Xujiahe Formation in Northwest Sichuan are important areas for natural gas exploration,and reservoir quality is very important to the development scale of gas reservoirs. The reservoir characteristics and main controlling factors of Triassic Xujiahe Formation in northwestern Sichuan Basin were analyzed by using core,outcrop,seismic and logging data,and the favorable reservoir development areas were evaluated. The results show that:(1)The deep effective reservoirs of Triassic Xujiahe Formation belong to low porosity and low permeability reservoirs,which are mainly developed in delta underwater distributary channel and estuarine bar. The lithologies are mainly coarse sandstone and pebbly fine sandstone,and the reservoir space mainly includes primary pores,intragranular and intergranular dissolved pores and fractures.(2)The development of effective reservoir is mainly controlled by sedimentary microfacies,diagenesis and structural fracturing. The underwater distributary channel sand bodies are most favorable. The dissolved pores formed by dissolution and the transformation of primary pores effectively improve the porosity and permeability of sand bodies. The structural fractures produced by fracturing play an important role in the formation of effective reservoirs.(3)A large area of sand bodies are developed in the underwater distributary channel of delta front of Xujiahe Formation in the study area,and many primary pores were preserved in the early rapid burial process. In the process of late burial diagenesis,the organic acids produced in the process of hydrocarbon generation caused a large number of dissolved pores. A large number of fractures formed by Himalayan tectonic movement improved the reservoir physical properties.(4)The relatively high-quality reservoirs of Triassic Xujiahe Formation in northwestern Sichuan Basin are mainly distributed in Laoguanmiao-Wenxingchang-Zhebachang,Zhongtaishan,Liyamiao and Jianmenguan area.

Key words: underwater distributary channel, estuarine bar, low porpsity and low permeability, deep reservoir, Xujiahe Formation, Triassic, northwestern Sichaun Basin
