Researches on Hydro-frac Induced Reservoir Damage to Anthracite Coal Seams of Southern Qinshui Basin
There are over 600 CBM wells in southern Qinshui basin, which account for more than 50％ of the number in China. Anthracite ranked coal seams of southern Qinshui basin feature high adsorption capacity, low pressure and low permeability, therefore, selection of hydro-frac liquid and proportion of organic additives of the liquid are the top important things of reservoir protection. As a reference for CBM practitioners, this article outlines reservoir properties of southern Qinshui basin and research achievements on mechanism of hydro-frac induced reservoir damage, characteristics and sensitivities of the damages.
