Collective Technology Research Of 3D Seismic In Sea-land Transitional Zone In Er Jie Gou Area Of Liaohe

Er Jie Gou Area in the Sea-land Transition Zone of Liaohe has very rich hydrocarbon resources base and great exploration potential. Since the area was located between western concave and eastern concave, it is also every 3D area edge palace, its degree of exploration is relatively low; Complex physical geography conditions, for example, surface situation and sea stormy waves and sea water breed development etc, bring on atrocious exploration environment, and considerably affect seismic data quality, So there are 85 sq km2 of blank 3D acquisition area; Previous exploration , limited by temporal technique and equipment capability , causes to get the seismic data of bad quality, and it is difficult to satisfy the requirement of reservoir description and reservoir[0] forecast ; so it is necessary to do further exploration so that we can gain more abundant geological information and ascertain structural attitude of burial hill in the area and sand body morphology and distribution range of fracture development band.In this paper,according to the scientific research project Collective Technology Research of <3D Seismic Acquisition Technology In ErJie Gou in Liaohe Sea-land Transition Zone> of LHPEB, we mainly research the stimulating, receiving and observation system installation technology etc. of 3D seismic data acquisition in Sea-land Transition Zone of Liaohe. On the base of researching and analyzing seriously about seismic acquision technology in domestic other Sea-land Transition Zone, integrating the trait of seismo-geological condition in Sea-land Transition Zone, and regarding the practical condition of seismic construction carried out by Geophysical Exploration Company in Sea-land Transition Zone of Liaohe, we analyze the effect on seimic acquisition of the complicated natural environment in the Sea-land Transition zone,analyze synthetically previous acquisiton means, single shot record, section quality and seismo-geological condition in this area, and find the casue of affecting the data quality in Sea-land Transition Zone. According to the feature of seismo-geological condition in Er Jie Gou zone of Liaohe, we classify the earth surface with strong pertinence, and based on the classification of the earth surface, we carry out the research of stimulation and reception technology in the different earth surface condition;and research the water-land observation system of seismic exploration in the Sea-land Transition zone, the interface mode of different observation systems.Based on the practical seismic explorative engineering, we carry through spot test for research fruit. Through the analysis result of experiment data, the data quality has more improvement than ever . Our research gets the prospective effect ,and we research and find some means to resolve some problems, establish the base for further research.
