Abstract Surface microseismic monitoring is an effective method to evaluate the fracturing effect of horizontal well. By adopting the rectangular observation system, shallow-depth embedment and soil-covering coupling compaction acquisition techniques of high sensitivity geophones, obvious fracturing microseismic signals are obtained in shale reservoir in the horizontal interval of SYY-2HF well below 2000 m. The application of key processing technology including data normalization, noise suppression, velocity modeling and seismic source localization has effectively improved the imaging precision of low-frequency signals in shale reservoir. Through high-precision inversion positioning and interpretation technology, the paper objectively evaluates the fracturing effect of SYY-2HF well and puts forward suggestions for fracturing optimization.

Key words： microseismic monitoring fracturing shale oil horizontal well Songliao Basin
