摘要
近年来,头屯河组已成为准噶尔盆地腹部地区勘探主要目的层系.该区头屯河组主要为河流相沉积,储层以岩屑砂岩和长石砂岩为主,含高岭石、绿泥石等粘土矿物.主要储集空间类型为粒间孔隙、粒内孔隙和微裂缝.通过分析,确定该组段储层为低渗-中渗型储层,影响物性主要因素有原始沉积作用、后生成岩作用和构造作用等.
Nowadays, Toutunhe Formation has become one of the main prospected target stratas in central Zhunger Basin, Toutunhe Formation in this region was mainly fluvial facies sedimentation, and its reservoirs were mainly lithic sandstone and feldspar-porphyry sandstone, including many kinds of clay minerals such as kaolinite and chlorite. The pore in this formation was mainly intergranular pore, intragranular pore and microfracture. Through the analysis of sandstone properties in this formation, we confirmed the reservoir in this group is low-middle permeable reservoir, the main facters affecting the sandstone properties of the reservoir were primary sedimentation, epidiagenesis and tectogenesis and so on.
