国外“连续型”油气藏研究进展

Progress in the research of "continuous" petroleum accumulations abroad

国外非常规油气藏的勘探开发已经初具规模,部分非常规油气藏的地质特征具备连续性。对近年来国外"连续型"油气藏文献进行了大量调研与研究,总结了国外"连续型"油气藏的提出背景以及具体含义;概括了"连续型"油气藏的地质与开发特征,认为"连续型"油气藏圈闭界限不明确,大面积普遍连续含油气,浮力不是油气运聚主要动力,资源评价使用不同于常规油气藏评价方法的FORSPAN评价模型。

The exploration and development of unconventional oil and gas abroad have made significant progress, some unconventional oil and gas reservoirs have continuous geological features. It is meaningful to summarize the geologic features of continuous petroleum accumulations for guiding domestic hydrocarbon exploration. The background, definition and characteristics of the ＂continuous＂ petroleum accumulations were depicted through studying a number of related foreign papers. It shows that ＂continuous＂ petroleum accumulations have large spatial dimensions and indistinctly defined boundaries, and exist more or less independent water column, and can be assessed with FORSPAN methods different from conventional accumulations resource-assessment.
