Abstract

Abstract:

During implementing the recent “High-Quality and Efficient Exploration” strategy, evaluation and optimization of seismic exploration have attracted extensive attention. In processing and interpretation of the seismic data from the lithologic reservoirs in Junggar basin, a “Three Lists and One Countermeasure” method and its evaluation system are put forward based on a goal-oriented integrated workflow, and remarkable results have been achieved in field application. However, this evaluation system does not cover seismic data acquisition and mainly consists of some qualitative description methods. Therefore, by taking seismic data with effective bandwidth as a key indicator, a corresponding index system of seismic acquisition is proposed, then evaluation and optimization of seismic acquisition plan are contained in the evaluation and optimization system for seismic exploration, and finally the “Three Lists and One Countermeasure V2.0” is established. The optimized seismic evaluation system has been applied in multiple projects for lithologic reservoir exploration and remarkable results have been obtained. The methods proposed in this paper can be references to evaluating and optimizing seismic exploration for lithologic reservoirs in similar areas.

Key words: Junggar basin, seismic exploration, integration, evaluation and optimization, acquisition plan, high-quality and efficient exploration, effective bandwidth
