摘要： 苏里格庙气田二叠系盒8段内的主力储集层为一套中砂、粗砂和细砾岩,其复杂的成岩演化过程导致了储集层内孔隙演化的复杂性。为了指导该区下一步的深入勘探,本次研究运用多元逐步回归的分析方法,对苏里格庙气田孔隙发育的主要控制因素进行了分析。结果表明,研究区内砂岩储集层的孔隙度主要受沉积和成岩双重因素的控制。这种方法在该地区的成功应用不仅对在该地区寻找有利储集层提供了指导,也为同类问题的解决提供了参考。

Abstract: The major reservoir of Permian He-8 section in Suligemiao gas field is a deposit with medium sands, coarse sands and fine conglomerate. The complicated course of Diagenesis results in the complexity of pore development in the reservoir. This paper presents the analysis of major controlling factors of the pore development by means of multiple stepwise regression analysis in order to guide the further exploration. The result shows that the porosity of sandstone reservoir in the studied area is mainly controlled by both sedimentation and diagenesis. This method and conclusion could not only be as a guide for further exploring the favorable reservoir, but also offer positive basis for reference for similar study of other areas.

Key words: Suligemiao gas field, Permian, reservoir rock, porosity, controlling factor, multiple stepwise regression analysis
