摘要
针对大港滩海张东地区"井少、井距大、以地震资料为主"的特点,提出地震地质精细预测的思路、内容、方法和技术,在地震地层学、层序地层学、地震沉积学理论指导下,综合运用地震、测井等多种技术手段是进行岩性油气藏储层准确预测和精细描述的关键。由于研究区目的层具有横向变化大、储层物性非均质性强的特点,所以本文采用拟声波随机阻抗反演并结合地震频谱分析技术进行精细的岩性储层预测。预测结果表明,砂体的预测效果与测井资料解释结果吻合较好,可以作为油气分布规律研究及其综合评价的基础。
Faced with the characters of 'less wells,larger well interval and taking the seismic data as major source'in Zhangdong area of Dagang beach,the paper presented the idea,content,method and technique of fine seismic-geologic prediction.Integrative application of geology,sedimentology and multiple technical tools such as seismic and logging is key to carry out accurate prediction and fine description of lithologic oil/gas reservoir.Based on the characters of large lateral variation and strong physical non-homogeneity of targets in the studied area,the paper adopted pseudo-acoustic random impedance inversion and combined with seismic frequency spectrum analysis to carry out fine prediction of lithologic reservoir.The results showed that the sand-body predicted results was coincident with interpreted results of logging data,which can be taken as basis of studying oil/gas distribution regularity and integrative appreciation.
