泌阳凹陷老区地震采集技术探讨

泌阳凹陷经过近30年的地震勘探．大的构造和圈闭已基本查明．但未查明的资源量仍还很大。近年来随着勘探开发的不断深入，勘探目标越来越隐蔽．越来越复杂。为了寻找新的突破点．河南油田先后在泌阳凹陷的不同地区应用新技术新方法进行了高分辨率试验和高精度开发地震采集，总结出一套适合该凹陷地震地质条件的高精度地震勘探的资料采集方法．解决了该探区的一些勘探难题。在泌阳凹陷北部斜坡带具体落实了一批小断块、小构造．控制了一些地质储量，取得了较好的地质效果。

Discussion on seismic acquisition at mature exploration areas in the Biyang Depression

The Biyang Depression is the main oil producing area of Henan Oilfield. Major structures and traps have almost been found out after nearly 30-year seismic exploration. To detect new prospects, several high-resolution seismic tests and high-precision production seismic acquisition projects with new technologies and methods have been carried out successively in different areas of the Biyang Depression, which leads to a suite of seismic exploration methods. A batch of minor faults and structures were discovered in the northern slope zone of the Biyang Depression, which controls certain amount of geological reserves.
