摘要
塔里木盆地塔中地区奥陶系属于碳酸盐储集层发育有大量的裂缝和微裂缝,有着良好的勘探前景。对塔里木盆地塔中地区奥陶系段进行了裂缝发育情况的分析,并对储层的裂缝特征进行了研究。不同类型裂缝的成因、产状、规模、以及对油气的孔、渗能力都各不相同,对裂缝的研究有助于寻找油气的聚集与富集规律。在塔中地区裂缝的发育与断裂和褶皱有密切的关系,通过对塔中I号断裂带和塔中5、10井井区的裂缝的统计,再结合各种测井方法对塔中地区的裂缝发育的特征进行描述和评价。
The Ordovician of tazhong area in talimu basin belongs to carbonate reservoir which delvelops a lot of fractures and micro-fractures.The layer has great exploration foreground.The development of the fracture and studys the character of fracture in the Ordovician of tazhong area in talimu basin are described in this paper.The development of the fracture is relation to rupture and fold.This paper stats Irupture and the fractures of well of 5,10 in tazhong area and describes the distribution of fracture and estimates the character of fracture through well log.
