摘要
地震反演技术一直是地震勘探中的一项核心技术,其目的是用地震资料,反推地下波阻抗或速度分布,估算储层参数,并进行储层预测和油藏描述,为油气勘探提供可靠的基础资料。随着油气勘探程度的不断提高和勘探难度的加大,应用反演技术研究储层以及寻找隐蔽油气藏,提升为与应用地震来寻找构造油气藏同等重要的地位。本文简述了几种地震反演技术的原理和技术流程,进一步完善和丰富地震反演技术,使其成为一项成熟的岩性处理技术,在勘探开发工作中发挥重要作用。
The seismic inversion has always been a key technique in the seismic exploration, its target is that the distribution of the subsurface wave impedances or velocities are inverted to evaluate the reservoir parameters, implement the reservoir prediction and description by using the seismic data and provide the reliable data for the oil and gas exploration. Along with the increase of the difficulty and deepen the degree of the exploration, the seismic inversion techniques are used to study the reservoirs and explore the subtle reservoirs, thus make the technique as important as seismic in finding structural hydrocarbon reservoir. The principles and flowcharts of several seismic inversion techniques are discussed in the paper and seismic inversion techniques are further improved and made to be a mature processing techniques for lithology, therefore it can play an important role in the oil and gas exploration and development.
