Abstract

Abstract:

In order to meet geological needs of oil and gas exploration and development, new progress has been made in the research and development of prestack depth migration and integrated forecast of seismic reservoir. Seismic migration imaging technology has gotten the historic spanning from poststack to prestack, from time domain to depth domain, from integral difference method to difference method and from one-way wave to two-way wave. Development and use of Lightning pre-stack depth migration software have significantly enhanced the pre-stack migration processing capacity and imaging accuracy. Reservoir forecasting technological means have been enriched and improved constantly with extraction and analysis of curvature, texture and other new seismic attribute and development of prestack elastic inversion technique. The predicting targets have changed from conventional reservoirs to special and unconventional reservoirs. Forecasting technology have developed from prestack, single to poststack, integrated. Forecasting capability has improved from qualitative to semi-quantitative and quantitative and the forecasting parameters have evolved from the geometry to pore permeability and fluid bearing. Applying the new prestack depth migration and reservoir forecast techniques to the area where they are necessary can enhance imaging results of complex trap targets, such as piedmont, subsalt, carbonate rock and low-relief trap, so that forecast accuracy of non-homogeneous carbonate rock, thin sand layer and other complex reservoirs can be improved. In summary, the progress of the techniques mentioned has played an important role in the exploration and development of complex hydrocarbon reservoir.

Key words: pre-stack depth migration, reverse time migration, seismic attributes, prestack inversion, reservoir forecast
