利用井间地震技术优化钻井目标

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。

Using Crosswell Seismic Technology to Optimize Drilling Targets

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 attention 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.
