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.
