致密火山岩物性影响因素分析与储层质量预测——以马朗-条湖凹陷条湖组为例

摘要/Abstract

摘要： 在三塘湖盆地马朗-条湖凹陷条湖组二段晶屑玻屑沉凝灰岩致密储层中发现了工业油流。为了研究致密油的分布规律，通过研究岩相和成岩作用对火山岩储层物性的影响，进行了成岩作用数值模拟，结合条湖组二段的岩相图，预测了4类储层在平面上的分布。结果表明，角砾岩和凝灰岩的物性最好，玻屑晶屑沉凝灰岩和火山碎屑沉积岩的物性次之，熔岩的物性最差；随成岩作用的增强，储层的物性变差，储层物性是岩性和成岩作用综合作用的结果。常规储层（孔隙度≥9%）分布在马朗-条湖凹陷的南部，低致密储层（7%≤孔隙度<9%）和高致密储层（4%≤孔隙度<7%）分布在凹陷的中北部。在常规储层分布区，以寻找有效圈闭为主；而在致密储层分布区，则应注重储层和烃源的研究。

Abstract: Commercial oil flows were tested in the tight vitric and crystal sedimentary tuff reservoirs of the 2nd Member of Tiaohu Formation(P₂t²)in Malang-Tiaohu Sag,Santanghu Basin.In order to reveal the distribution pattern of tight oil,we studied the influences of lithofacies and diagenesis on physical properties of volcanic reservoirs.And plane distribution of four types tight reservoir of P₂t² were predicted through numerical modeling of diagenesis and in combination with lithofacies map.The results show that the quality volcanic reservoir decreases with increasing levels of diagenesis;Pyroclastic rock and tuff are optimal reservoirs,followed by vitric and crystal sedimentary tuffs and pyroclastic rocks,and lavas show the worst reservoir property.The conventional reservoirs(porosity≥9%)distribute in the southern Malang-Tiaohu Sag,and slight tight reservoirs(7%≤porosity<9%)and strong tight reservoirs((4%≤porosity<7%)are located in the central-northern of Malang-Tiaohu Sag.Effective traps are the main exploration targets in area with conventional reservoirs,while the reservoirs and hydrocarbon source should be the focuses of study in area with tight reservoirs.
