Abstract

There are many factors restrict the exploration and development of subtle reservoir in the deep lake area. The accurate description of reservoir distribution is the important factors of oil and gas exploration and development. Taking the exploration in Yingzijie area as an example, through the research of seismic facies division and sand body identification, we formed the “five steps” method for reservoir description of lithologic reservoirs in fan delta, which includes using seismic frequency extension to identify reservoir, using seismic response to show characteristics, using seismic facies to define zones, using multi-well joint constrained inversion to determine fine sand bodies and using frequency divider to interpret boundary. The exploration practice shows that this technology has good effect, and can be used to establish models of seismic wave form for different type of sand bodies, show the contact relationship of crosswise sand, confirm the facies configuration of delta front and prodelta, and predict favorable zones of lithologic reservoir.
