Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water.
The middle oil-member is characterized by medium-sized sandstone and pebbled sandstone, with fair sorting and subangular sphaericity.Rock types mainly were feldspar debris sandstone.
Nonsandstone reservoirs between salt beds of Qianjiang Formation in the Qianjiang Sag of the Jianghan Basin are mainly composed of dolomicrite,glauberite rock,mudstone and their peperite.
The sandstones of the Turpan Basin belong mostly to graywacke and their compositional and textural maturity are generally low,indicating a strong erosional and rapid transportational environment.
Fluorinated polymers were applied to sand stone heritage in order to increase its compressive strength and consolidation as well as to enhance its resistance to desegregation by water.
