枣北地区火山岩油藏勘探历程及开发实践

Exploration history and development practice in volcanic reservoirs of Zaobei area, Huanghua depression

应用二维地震高分辨率处理、岩心精细描述与系列分析、测井单井解释、地震资料精细解释、储层横向预测与含油气检测、综合油藏描述及火山岩工程工艺等多项技术,对黄骅坳陷枣北地区火山岩油藏的勘探历程及开发实践进行了研究;对该油藏在不同勘探、开发阶段的技术应用情况及勘探研究思路进行了论述。针对其油藏特征,采用掺水降粘、加深泵挂及酸化等工艺改善开发效果,为类似油藏的勘探,开发提供了借鉴。

This paper studies the exploration history and development practice of volcanic reservoirs in Zaobei area of Huanghim depression by applying high resolution 2D seismic processing, accurate core description and series analysis, single well logging interpretation, accurate interpretation of seismic data, reservoir lateral prediction and oil and gas detection, integrated reservoir description, and volcanic engineering technique. The application of techniques and the strategy of exploration are also discussed for different exploration and development stages. According to reservoir characteristics, techniques such as water blended viscosity reduction, deepening pump setting depth, and acidizing have been used to improve development effect, thus providing reference for exploration and development of similar reservoirs.
