Hydraulic fracture, as a stimulation treatment, has been widely used in process of oil exploring in oil well. But in tight sandstone reservoir, it still exist many problem due to compactness, low-permeability, hardness and brittleness characters of the sandstone. To resolve the problem above-mentioned, this text considering the low natural productivity status of tight sandstone reservoir in Yanji Basin, to analyze the reservoir characters of tight sandstone reservoir base on density testing and mechanic parameters testing of the stone. The results shown that the special reservoir characters of tight sandstone sand lead to high fracture pressure of formation, poor connectivity of fracture, filtration and backflow problems of fracturing fluid. So we put forward reasonable recommendations for fracturing to resolve the problem above-mentioned. Through the application of oriented perforating technology, improvement of fracture fluid system and fracturing technology, provide a new effective technological measure for fracturing in tight sandstone, and promoting the development of fracturing technology in tight sandstone reservoir.
