Abstract

Abstract:

Characteristics of Kezilesu Group sandstone reservoirs and factors controlling their development are investigated based on the analysis of routine thin-sections,cast thin-sections,physical property and grain sizes.The results show that the reservoir rocks are dominanted by feldspathic litharenite and lithic sandstones with low porosity and permeability,and the pore types are mainly secondary pores including intragranular dissolved pores,intergranular dissolved pores and micropores.The mercury intrusion curve has high displacement pressure,indicating that the sorting of pore throats is poor and the pore structure feature in small pores and fine throats.The development of Kezilesu Group sandstone reservoirs in Akemomu gas field has strong correlation with grain sizes,debris content and diagenetic compaction,cementation and dissolution.For reservoir rocks were deposited under the control of braided rivers,their quality improves with grain size enlarging,debris content increasing and enhancing of dissolution.On the contrary,compaction and cementation of carbonate,clay and siliceous mineral formed during the post-diagenesis have adverse effects on reservoir rocks.

Key words: diagenesis, sedimentary facies, sandstone, reservoir characteristics, Akemomu gas field, northwest Tarim Basin
