The reflected wave of Lei-1 seismic profile measured during the high resolution exploration in 1991 is characterized by poor continuity and weak energy. Aimed at overcoming these weaknesses and solving three geological problems(thin oil,-gas-bearing layer, low porosity and the relationship between the oil-,gas-producing capacity and the development of fissures in Sichuan basin), the authors carried out the test of high resolution seismic exploration technique in 1997 so as to find out the structural form and the distribution of faults along Lei-1 profile and, as a result, obtained the collection equipment disposition and the field working technique related to the high resolution seismic exploration, thus broadening the field of oil gas exploration in Sichuan basin.
