Abstract:

This paper, aiming at the narrow sand body and thin oil-bearing bed in Putaohua reservoir in eastern Daqing area, introduces a seismic interpretation software and applies the seismic technology to recognize small faults, small sand bodies and small structures, which has increased the drilling efficiency. To the complicated reservoirs and oil-water relation, the author employs fine structure interpretation, undee aberration technology, fuzzy NN, multi-well inversion, reservoir modeling and forecast, seismic facies interpretation and 3D visualization to increase the descriptive precision of complicated reservoir, and applies the stacked processing technology of 3D seismic data to provide a technical support for the drilling development in the eastern Daqing area.

Key words:

摘要：

针对大庆外围东部地区葡萄花油藏为窄砂体、薄油层复杂岩性油藏的地质特点，本文简要回顾了通过引进并学习先进的地震解释软件，应用开发地震技术，精细识别小断层、小砂体及微幅度构造的“三小技术”，实现了钻井成功率逐年提高的开发效果。并针对油田开发难度逐年增大，储层条件和油水关系日趋复杂的情况，综合应用精细构造解释、波形畸变技术、模糊神经网络技术、多井约束反演、储层正演技术、储层预测技术、地震相解释技术及三维可视化技术，提高了复杂岩性油藏的描述精度，并应用三维地震资料连片处理技术，为大庆外围东部地区后继的钻井开发提供技术保障。
