以川西新场地区须二段致密砂岩储层为研究对象，运用大量薄片资料及物性数据，对储层特征进行分析，利用岩心、测井及地震手段进行裂缝和流体的识别及展布预测，进而达到对储层进行综合评价及优选有利开发区的目的。研究表明须二段次生孔隙及微裂缝发育，裂缝以低角度缝为主，主要沿断层及构造两翼的膝褶带分布。有效储层主要受控于沉积相、成岩、构造及成藏作用，其中溶蚀作用和构造的破裂作用是最重要的控制因素。Ⅰ类储层发育区主要位于上亚段Tx22和中亚段Tx42砂组构造高部位或者大的断裂带附近。结论认为：中、上亚段F3断层两侧为最有利的开发区，其次为上亚段的F1断层南段两侧和中亚段的新10-川科1井区。研究结果可以指导川西新场须二段气藏的有效开发。

In the study of dense sandstone reservoir in the Second Member of Xujiahe Formation in Xinchang area,the reservoir characteristics were analyzed using approved slice and properties data acquired with test methods.Fractures and fluid were identified and predicted using core,logging and seismic methods,to guide the synthetic evaluation of reservoir and the favorable block optimization.It is indicated that secondary pore and micro-fracture develop mostly in target formation,and fractures are mainly low-angle fractures,spreading along fault and fold-belt in structural limbs.The effective reservoir are mainly controlled by sedimentary facies,dia-genesis,structure and petroleum accumulation,however,corrosion and crack are the main control factors.The blocks of reservoirⅠ locate in high structural place or nearby faults in Tx22 and Tx42 .It is concluded that the areas of two sides of F3 fault in middle and up sub-segments are the most favorable blocks,while two sides of southern edge of F1 fault in up sub-segment and Xin10-Chuanke1 well area in middle sub-segment are the sec-ondary.The study results are significant in effective development of the Second Member of Xujiahe Formation in Xinchang area.
