摘要:
甘谷驿油田长6油层为低孔、特低渗透细喉型碎屑岩储层。根据地面相似露头裂缝观测、岩心 裂缝描述、镜下薄片裂缝观测、地层倾角裂缝解释及注水开发生产动态表明,长6油层是地面以东西和 南北向宏观构造裂缝发育为主、地下主要以东西向为主的微裂缝。这种裂缝在地下大部分呈孤立、闭合 状,在现今北东向80°的最大水平主应力背景下,油井压裂投产使东西向微裂缝连通并优先开启,其次为 北西向裂缝。南北向微裂缝始终处于挤压状态而闭合,因此,造成油田注水开发注入水沿东西向裂缝油 井水串,南北向油井见效差。
Abstract:
The Chang 6 reservoir belongs to low porosity and excessively low permeability micro throat clastic rock reservoir. By field investigation, rock core and slices observation, and the dip log interpretation, it is found that, in the Chang 6 reservoir, the frac- tures are extend in the direction of near EW and SN on the ground surface and orientated east-west underground and most of the fractures are alone and closed. Due to the present action of the greatest horizontal stress with an orientation NE80°, EW-NW tren- ding fractures are connected and opened successively by the oil well fracture. However, the SN trending fracture is closed due to compression. Therefore, during the water injection, water is going forward along the EW trending fracture, but the result of water injection of SN trending oil well is bad.
