留北地区二次三维地震资料采集方法研究
|
摘要
作为华北油田主要产油区的冀中地区,三维地震已经基本连片,勘探程度相当高。通过精细的地质论证, 认为冀中留北地区具有精细勘探和增储上产的潜力,有必要进行二次三维采集。实践中,应用了多种模型的观测系统设计、精细表层结构调查和多种方法联合调查、提高控制点精度等技术,提供了准确的激发井深、表层结构模型和静校正方法等参数资料。应用效果表明,所得资料的分辨率和信噪比均满足该区当前构造精细解释和岩性勘探的要求。
Jizhong area, the main oil producing area of North China Field, has been in high degree of exploration at present. 3-D seismic prospecting blocks have been connected. It is believed that there is large potential capacity of increasing oil reserves and production at Liubei area according to fine geological argumentation. The second 3-D acquisition was carried out at Liubei area. With multi-model based layout design, fine investigation of near surface structure, joint investigation of various methods, and improvement of control point precision, we determined not only the accurate shooting depth, but also the near surface structure model and static correction method. The resulted data can meet the requirements of fine structure interpretation and lithologic exploration in terms of resolution and S/N in this area.
