SBIR Phase I: Variable Azimuth Wave-Equation Imaging (VAWEM)

该小型企业创新研究（SBIR）一期项目旨在研究一项关键技术的可行性，该技术旨在利用变方位角波动方程偏移（VAWEM）提高深水复杂地质构造的地震分辨率和成像。VAWEM将提供比目前拖曳海洋拖缆数据更高的分辨率和精度，并且计算成本显着降低。这种先进的成像方法将提高新油田发现的成功率和成本效益，并提高现有油田开发的采收率。这项技术在业内尚不存在，但它是一项根本性的革命性进步，是任何地震处理系统的必要组成部分，该系统使用波动方程方法对三维叠前数据进行成像，以成像深水、盐下复杂地质构造，这是现代油气勘探的重点。

This Small Business Innovation Research (SBIR) Phase I project proposes to investigate the feasibility of a key technology designed to enhance seismic resolution and imaging of deep-water complex geologic structures by using variable azimuth wave-equation migration (VAWEM). VAWEM will provide much greater resolution and accuracy than what can be accomplished today for towed marine streamer data, and at significantly less computational cost.This advanced imaging methodology will improve success rate and cost effectiveness for new field discoveries and increase recovery efficiency for the development of existing fields. This technology does not exist in the industry, it is a fundamental revolutionary advance, and is a necessary building block in any seismic processing system that images 3-D prestack data using wave-equation methods for imaging deep water, under-salt complex geological structures which are the focus of modern oil- and-gas exploration.
