KZ区块白垩系过路井补孔改层均表现出良好的生产能力,具备一定的开发潜力,但目前补孔改层措施潜力论证以单井测井资料为主,缺乏系统研究.通过对KZ区块白垩系开展构造描述、精细地层对比、储层展布特征及油气分布规律研究,结果表明:KZ区块白垩系主要发育断鼻圈闭,"反向"断层更容易形成断层遮挡油气藏,微幅度构造控制油气的富集,油气成藏模式为他源断控、垂向及侧向输导.
Characteristics of Cretaceous reservoir formation in KZ block of Tahe Oilfield
The Cretaceous pass-through wells in KZ block show good production capacity and have certain development potential.However,at present,the potential demonstration of reservoir improvement measures based on single well logging data is lacking of systematic research.Through structural description,fine stra-tigraphic correlation,reservoir distribution characteristics and oil and gas distribution,the results show that the Cretaceous system in KZ block mainly develops faulted-nose traps,"reverse"faults are more likely to form fault-blocked oil and gas reservoirs,micro-amplitude structure controls oil and gas accumulation,and oil and gas reservoir formation modes are isolated fault-controlled,vertical and lateral transport.
