利用井间地震技术优化钻井目标

Using Crosswell Seismic Technology to Optimize Drilling Targets

井间地震反射波的主频大约是地面地震反射的2-10倍,因而井间地震具有更高的分辨率,同时对成像精度的要求也就更高;井间地震技术作为油气田勘探开发领域的一项新技术,在最近几年中得到了长足发展。本文详细介绍了国外油气田利用井间地震技术预测高孔、高产的砂体位置,以及在油气藏开发阶段如何利用井间地震技术优化钻井目标的过程。

The main frequency in the crosswell seismic reflection is 2--10 times more than that in the surface seismic reflection, so the crosswell seismic technology has much more high resolution, and at the same time, it requires more precision for image. As being a new technology, it has been paid more attentio＇n in oil and gas exploration and development and has made much progress in recent years. This paper introduces two practical case studies. one is to use crosswell seismic technology to predict high porosity and high channel sand production; the other one is to use the technology to optimize drilling targets in oil and gas exploration and development.
