【摘要】 塔河油田塔中K1区块石炭系碎屑岩是该区的优质储层。储集砂体在工区内广泛分布,根据地震反演、钻井、沉积岩石特性分析得出卡拉沙依组砂岩在剖面上主要表现为透镜状,砂体中间厚向两边变薄,巴楚组砂泥岩互层段在该工区的沉积相主要表现为扇三角洲-冲积扇沉积体系及滨岸河口湾沉积,储层主要集中于砂泥岩和生屑灰岩段。储集层特征的研究对寻找该区岩性油气藏扩大油气勘探有着重要意义。更多还原

【Abstract】 Carboniferous clastic rocks in Block K1 of Tahe Oilfield was a good quality reservoir in the area.Sands were widely distributed there,according to the seismic inversion,drilling,sedimentary rock analysis,it was indicated that sandstones in Kalashayi Formation were mainly in lens shape with thickness in the middle and thinning on both sides,Bachu group and the interbeds of glutenite were presented mainly as fan-delta-alluvial fan depositional systems in the work area.Sedimentary coastal estuaries were mainly concentrated in glutenite and bioclastic limestone.It is of great significance to study the reservoir characteristics for expanding oil and gas explorationin lithologic reservoirs.更多还原
