| Exploration course of passing nearly 40 years of visiting area of Liao he, We have already entered meticulous seismic exploration at present, Exploration targets and goal to hide and shift with the deep layer direction to tiny geological body, complex rock, reservoir, so have high quality of the seismic date is important, Wu must meet high SNR, high resolution and hi fi (high fidelity) requirement of gathering materials while the seismic acquisition. Generally , The seismic date is relatively bad in the Liao he peripheral basin, The SNR of the three-dimensional seismic date is lower too, And it influences SNR every index of date collection directly to the quality of the shooting, to studying the old date, for example, Jiao li ge, Lu jia pu, Nai man, Systematic conclude of shooting condition in the Liao he peripheral basin area: 1 well depth, well depth on the comprehensive influence that should fully consider shooting frequency and refracting many times , chooses better shooting when stimulate the rock under one high speed layer (3-7)M, improve the materials SNR of single shot; 2. dynamite weight. Single well dynamite (2-6) kg (stimulate the factor specifically confirmed by the test). 3. combination well. Small dynamite in single well, the wavelet is mainly high frequently, guarantee the improvement of the resolution Analyze that shooting the quality of the recorder in the test, Summarize best definite method and principle which shooting parameter, shooting is very important. in low SNR area, there are corresponding characteristics to shooting factor. on the side, to the situation in the peripheral sand dune area in recent years, pointed out the sand dune shooting effective method and implementation step that ensures enough energy, have further directive significance to seismic record in the sand dune area in the future .
