GEOLOGICAL CHARACTERISTICS AND MODELS OF FAULT-FOLD-FRACTURE BODY IN DEEP TIGHT SANDSTONE OF THE SECOND MEMBER OF UPPER TRIASSIC XUJIAHE FORMATION IN XINCHANG STRUCTURAL BELT OF SICHUAN BASIN, SW CHINA

Geological characteristics and models of fault-fold-fracture body in deep tight sandstone of the second member of Upper Triassic Xujiahe Formation in Xinchang structural belt of Sichuan Basin, SW China

In the second member of the Upper Triassic Xujiahe Formation (T3x2) in the Xinchang area, western Sichuan Basin, only a low percent of reserves has been recovered, and the geological model of gas reservoir sweet spot remains unclear.Based on Dipping Powder a large number of core, field outcrop, test and logging-seismic data, the T3x2 gas reservoir

Strength, thermal conductivity and sound absorption of cellular lightweight high calcium fly ash geopolymer concrete

In this research, the effects of foam content on mechanical property, thermal property and sound absorption of cellular lightweight geopolymer concrete (CLGC) were studied.The geopolymer mixtures were made with 15 M NaOH solution, sodium silicate/NaOH ratio (NS/NaOH) of 1.00, sand/ash ratio of 1.25, liquid/fly ash ratio of 0.4.The foam contents wer
