梨树断陷高精度三维地震勘探效果分析
|
摘要
针对梨树断陷的断块小、断裂带复杂、断陷深度大,火山岩发育等特点,吸取老三维地震资料的采集经验,采取目标观测系统优化技术、以精细表层结构调查为重点的最佳激发参数优选技术、以检波器类型与组合选择为特色的接收参数优选技术等,在梨树断陷进行了高精度三维地震采集,取得了品质较好的地震资料,资料的信噪比和分辨率大幅度提高。高精度三维地震勘探的实施发现并落实了一批构造,实施了多口钻井,其中十屋8井在沙河子组首次获得高产油流。
The Lishu Fault Depression has the characteristics of small faulted blocks,complicated faulted belt,deep fault depression and developed volcanic rock.Based on the acquisition experience of old 3D seismic data,by adopting target geometry optimization technique, optimal shooting parameters selecting technique focusing on detail surface structure investigation,receiving parameter optimization technique featuring on the selection of geophone type and array pattern,high-precision 3D seismic data acquisition was carried out in Lishu Fault Depression.Through the data acquisition,good-quality seismic data was achieved characterized by large improvement of S/N and resolution of the seismic data.Meanwhile,a batch of structures were discovered and identified,and some wells were deployed and drilled.For the first time,well Shiwu8 obtained high-production oil flow.
