Abstract:

As oil field exploration technology develops, 3D seismic data have been covering the vicinity of Daqing oilfield. In order to understand the structure, lithology in this area and to look for new reserve, it is necessary to process and interpret the oil exploration data. This paper, taking Putaohua and Fuyang oil-bearing sequences as target beds, processes and interprets the 3D seismic data in Sanzhao area in high resolution. Combined with geology, logging, oil testing data, sedimentary facies, prioritizes the favorable oil-bearing areas, discovers a few oil-bearing blocks, which have been put into production. The joint processing technology has been proved for its validity.

Key words:

摘要：

随着油田勘探技术的不断发展，大庆外围三维地震勘探区块逐年增加，并已连接成片。为了加深对本地区地下构造特征、岩性发育情况进行整体认识和评价，加快未动用储量的动用步伐，寻找今后的打井区块，连片处理、解释、统一成图已是油气田勘探开发的必然趋势。以葡萄花和扶杨油层为目标层，本文对三肇地区1 470 km2的三维地震资料进行了高分辨率连片处理，同时对重新处理的三维地震资料进行了精细解释。结合地质、测井、试油等资料，在沉积相和沉积微相的控制下，参考储层预测图，进行了含油富集区和有利布井区的优选。在原来没有提交石油探明储量的地区，发现了多个含油富集区，现已投入钻井开发，并取得了较好的开发效果。通过对连片处理解释技术的分析和总结，肯定了连片处理解释的效果。
