保定凹陷双复杂地区高精度地震采集关键技术
Key technology of high-precision seismic acquisition in bicomblex area of Baoding Sag
摘要
Abstract
The Baoding Sag is located in the western slope of Lixian County in the Jizhong Depression of the Bohai Bay Basin,with the Taihang Mountain front fault as the boundary on the west side.It is a dustpan shaped fault depression formed by the control of the Taihang Mountain eastern fault zone,with a western fault and an eastern overlap.The underground conditions in this area are complex,with not only shallow geological targets and thin lithological reservoirs,but also a large number and small scale of faults.At the same time,faults intersect with each other and frequently transform in space,posing high requirements for the vertical and horizontal resolution of seismic data.In addition,the complex surface conditions,diverse types of obstacles,and numerous prohibited excitation zones in the area pose significant challenges to seismic acquisition work.In the past,oil and gas seismic exploration in this region mainlyfocused on mid to deep geological targets,and relatively mature seismic exploration techniques have been developed domestically for this area.With the continuous deepening of geological research on new targets and fields in the old oil areas,a new understanding has been gained of the oil and gas enrichment in the Baoding area.It is believed that the oil and gas enrichment layers are mainly concentrated in the first section of the Shahejie Formation and the Guantao Formation in the middle and shallow layers.Therefore,in response to the complex exploration challenges of both surface and underground for the relatively shallow geological targets in the Baoding Sag,it is proposed to adopt wide-azimuth high-density three-dimensional seismic technology,and simultaneously support the geometer body coupling quantitative implementation technology,multi-domain complementary seismic acquisition implementation technology,and near-surface dual nvestigation technology.High quality seismic data and good geological effects have been obtained in the Baoding Sag,helping to achieve significant breakthroughs in oil and gas exploration and providing reference for seismic exploration work in similar areas.关键词
