According to the research on sand control technology for shallow gas reservoirs in this area,integrating the formation pre-treatment by alcoholic and mud acidizing process to improve reservoir circulation,this paper presents a matching technology of sand control for Yanjia gasfield,which is reliable for the development of shallow gas reservoirs.

The condition of extracting pigment from purple wheat bran with acidified alcohol were optimized through single-factor and orthogonal designed experiments.

A study of the characteristics and mechanisms of soil acidification in the Dongting Lake region in Hunan Province,South China;

The incubation experiment studies on the influence of soil acidification on greenhouse gases emission;

The factors of influence accelerating soil acidification under acidic deposition;

Effect of simulated acid rain and its acidified soil on lipid peroxidation of wheat seedlings;

In such acidified soil,the generation of biomass and physiological activities of wheat(Triticum aestivum)seedlings were reduced.
