当前,石油天然气资源勘查开发研究的关键问题集中在提高地震勘探分辨率和信噪比、确立实用的裂隙性储层弹性波模型和发展新技术勘查深层油气田三个方面。这些研究促进了应用地球物理学理论和方法的深入发展。本文根据出访西欧及自己的研究实践对以上三方面的进展作一评述。 At present, the key problems in the exploration and development of oil and natural gas resources are concentrated on improving seismic resolution and signal-to-noise ratio, establishing practical elastic reservoir model for fractured reservoirs and exploring new technologies for exploration of deep oil and gas fields. These studies have promoted the in-depth development of applied geophysical theories and methods. This article gives a commentary on the progress of the above three areas based on his visit to Western Europe and his own research practice.
