裂缝型油气藏勘探评价面临的挑战及发展方向

The present situation and research direction of evaluation methods in fracture type reservoir

裂缝型油气藏,即致密砂岩裂缝、碳酸盐岩裂缝、泥岩裂缝、火山岩或变质岩裂缝等储层形成的复杂油气藏,已经成为国内外油气勘探开发的焦点,常规勘探理论和方法在裂缝型油气藏评价中面临许多挑战,常常显得无能为力.本文从裂缝型油气藏储层评价出发,分析各种常规预测裂缝有利发育带方法的优势和局限性,提出裂缝性油气藏勘探评价新理论新方法的基本出发点和思路,并给出了具体的应用实例.

In recent years, Evaluation of fracture type reservoir, namely dense sandstone fracture, carbonate fracture, mudstone fracture, volcanic fracture or metamorphic fracture etc, is one of the focuses of oil and gas exploration. The conventional reservoir evaluation methods face the challenge in fracture reservoir. Based on the research of the evaluation methods of fracture reservoir, the advantage and disadvantage of conventional methods to predict the favorable fracture zone is reviewed in this paper. According to the advancement of the research, the new idea in the special reservoir evaluation is discussed. Some examples were presented.
