| 摘 要： | 冀东油田老爷庙地区地震工作始于1976年。由于目的层反射弱、多次波发育,地震资料品质差,为此二次三维采集时选择了近似全三维的观测系统;采取检波器下井单点接收,中密中爆速炸药激发;科学合理的现场设计,完善的质量监督体系及严密的施工使得所采集资料的覆盖次数、偏移距、方位角分布基本均匀,保证了高质量的剖面。

| Abstract: | Seismic exploration in Laoyemiao area of Jidong Oil Field was started in 1976. The quality of seismic data was poor because complex and special geological conditions make the reflectivity of the objective formations weak and multiples strong. Therefore, apparent true 3D geometrics was selected in second 3D seismic survey. Geophones were located in borehole for single point receiving. The dynamite with middle density and shoot speed were adopted. The rational site design, perfect quality control system and serious field operation make the distribution of fold, offset and azimuth basically even so that the qualified seismic sections were obtained. |
