东濮凹陷开发地震的应用及前景

东濮凹陷码维地震覆汪面积约3600km^2，已实现了全凹陷含油气区的三维连片，三维地震、VSP技术和井间地震技术应用较为广泛。根据东濮凹陷目的层地质特点，开展了井约束地震反演、深层开发地震、构造复杂区地震，井地联合勘探试验，井间地震技术试验等开发地震技术应用研究，取得了良好效果。随着地震勘探技术及硬件的发展，在东濮凹陷油气田开发后期急需解决的小断块构造精细解释、储集层精细预测、油藏开发过程中油、气、水分布的监测，储集层裂缝识别、油气层识别等问题的应用前景方面，开发地震技术具有巨大的应用潜力。图3参6

The application and prospect of production seismic technique in the Dongpu Depression

The covered area of the 3D seismic in the Dongpu Depression is about 3600km~(2) where 3D linking is completed and 3D seismic, VSP and crosshole seismic technique are widely used. On the base of geologic feature of the Dongpu Depression, production seismic technique, such as borehole restraining seismic conversion, deep production seismic, seismic in complex structure area, borehole-ground combinating exploration test, crosshole seismic technique test, etc, are practically used and the good effectiveness have been achieved. With the developments of seismic exploration technique and hardware, production seismic technique will have a great potential and future for structure interpretation of small block, reservoir prediction, and monitor of the distribution of oil-gas-water in the process of production, reservoir fracture of reservoir production and reservoir fracture analysis.
