摘要
在注水开发过程中,由于储层平面矛盾突出,含水上升速度较快。在总结研究区长8油层组见水现状基础上,通过见水介质的矿化度指标,研究认为研究区见水类型为注入水;通过示踪剂监测、动态验证、干扰试井综合方法,对见水方向进行分析,研究认为研究区长8油层组主要见水方向为NE75°。研究区天然裂缝发育,以北东方向裂缝较为发育,微裂缝发育是Z252区块见水的主控因素。
Water rises rapidly in the process of water flooding due to flat contradiction of reservoir. The type of water out is confirmed as injected water by use of salinity indicators of the aqueous medium based on the status of water out in Chang 8 reservoir.The direction of the water out has been analyzed by tracer monitoring,dynamic authentication,and integrated approach of interference well test. The results suggest that the main water out direction in Chang 8 reservoir is NE75°. Natural fractures in the area are more developed in the north of the east. The micro-fractures are main factor contributing to the water out of Z252 block.
