摘要: 在对吐哈盆地红台地区进行以岩芯铸体薄片和普通薄片为基础的储层微观特征研究过程中,发现在许多井中发育分布较广的粒内裂缝。针对工区内断层下盘裂缝发育区的范围和裂缝的发育程度均明显比上盘要小,并且离断层越远,裂缝发育越少,在宽度和条数上也有变小的趋势等特点,经过分析和论证认为此种裂缝不是由正常的地层沉降压实产生的,而是挤压环境下逆冲断层作用产生的。经统计分析发现裂缝带发育的宽度与断层的断距存在密切的关系。利用统计和回归等方法提出了一种预测裂缝带发育的宽度与断层的断距关系的方法,可以定量预测裂缝发育带的宽度。

Abstract:

In the process researching the reservoirs in Hongtai area,which is based on the casting and conventional thin section inspection data,many intragranular

fractures are found.Because the development scope and degree of fractures in the downdip block are lower than the ones in hanging wall in the research area,the further the

distance from the wall is,the lower the development degree,and the width and length of the fractures decrease with the distance increasing,after researching and

analyzing the fractures,it is recognized the origin of the fractures is not by normal compaction,but the influence of reverse slip fault.Because there is an close

relationship between the width of the intergranular fractures and the distance from the wall,a method by using regression and statistics is put forward to forecast the

relationship between the width of fracture development belt and the distance from the wall,which can qualitatively forecast the scope of fracture development.

Key words: Tuha Basin, Hongtai area, intragranular fracture, regression analysis, quantitative forecast
