With the progress made in exploration, Daqing exploration area has entered the exploration stage of thin interbedding lithologic oil and gas reservoirs with low-permeability and compact gas layers, and the fracturing and stimulation techniques are becoming the conventional techniques for increase of production and reserves.

In order to know the conditions of shallow tight sand gas reservoir formation,the gas-source rock was studied in Dongliang district in the Fuxin basin on the basis of organic petrological and geochemical study.

Aimed to the problems of the abnormal high fracturing pressure,un-conspicuous operating measures effect and the short valid date during the fracturing process of deep compacted gas reservoirs in western Sichuan,blasting-acid fracturing complex technology was proposed.
