Abstract


Two boundary ditches , Liaohe transitional zone with strong oil and gas resource base and huge potential for exploration . Area located between the the Western Depression eastern depression , while blocks of three-dimensional joints , the relatively low level of exploration ; very complex natural and geographical conditions , land surface conditions , sea waves , and the development of the mariculture industry factors construction environment is very poor , largely affecting the quality of the data in the area , has the region still 85km ~~ 2 blank area of the three - dimensional acquisition ; past exploration by capacity limitations of the technology and equipment , resulting in poor quality of seismic data , it is difficult to meet the needs of the reservoir description and reservoir prediction ; Therefore , the need for further exploration , for richer geological information , the implementation of the region buried hill structural form of fracture zone and sand body morphology and distribution . Relying Liaohe Petroleum Exploration Bureau, technical innovation and scientific research projects Liaohe sea transition zone two boundary ditch 3D seismic acquisition \Analysis of the sea beach area complex natural environment of seismic acquisition 's impact ; on this area in the past acquisition method to a single shot and profile quality and seismic geological conditions conducted a comprehensive analysis to find affecting Tanhai data quality ; according to two boundary ditch area earthquake characteristics of geological conditions , the specific surface classification ; surface classification based on different surface conditions of excitation and reception technology research ; transition zone seismic exploration amphibious observing System and its docking . Relying on the actual seismic exploration project , the research field trials . From the results of test data analysis , data quality has greatly improved compared to the past and old , the study achieved the desired results , and laid the foundation for further work .
