摘要
根据川西松华镇 -白马庙地区各井裂缝发育特征 ,结合声发射资料 ,指出区内存在构造缝和区域性裂缝类型 ,区域性裂缝在构造平缓区所起的作用较大 ;指出岩性、结构面和应力场强度是控制裂缝发育的地质因素 ;讨论了区域应力场方向和裂缝走向 ,初步评价了区域性裂缝相对发育区 ,并根据砂层厚度对裂缝间距进行了估计。
The authors classify fractures into the construction fracture and regional fracture according to the character of each fracture and AE data of wells. They point out that lithology, structural plane and stress field intensity are geological factors which control the fracture development. They also discuss the regional stress field directions and fracture cross pitch. At last they evaluate the developing regions of fractures and estimate spaces between fractures according to the sandlayer height.
