长庆气田靖边区井位优选地震技术

Earthquake Technology for Optimizing Well Positions in the Qingbian Area of Changqing Gas Field

为提高开发井钻探成功率,长庆气田在开发阶段充分利用该区物探地震地质解释成果即较成熟的奥陶系顶部侵蚀沟谷解释等地表储层横向预测技术,结合储层波形特征优选确定开发井位,取得明显成效。

In order to develop the success rate for well drilling and exploration,at its primary stage,Changqing Gas Field tried to make full use of the explanation for earthquake technology in this area.In another word,it tried to make use of the landscape orientation forecasting technology of the storing layer on the earth's surface.By com- bining the feature of waving shapes in storing layer,it optimized the position for developing wells and has got obvi- ous effect.
