【摘要】 渤海海域旅大油田油水井注采实践表明,北东—北北东方向注采井网为优势受效方向,这与储层砂体呈北西—南东向展布的以往认识相矛盾。具右旋走滑性质的辽西一号断层由分段的弧形断层相接而成,构造转换带控制了油田储层展布,这一认识获得了地震属性、重矿物分析的支持。重新编制了主要油组的沉积体系图。旅大油田的储层展布方向为北东—北北东向,这一新认识对储层精细描述、水淹规律分析及剩余油挖潜等具有一定指导意义。更多还原

【Abstract】 The NE-NNE orienting pattern of injection-to-production wells is preponderant in practice in offshore Lüda Oil Field, Bo Hai. This orientation is discrepant with the past standpoint that the Oligocene Dongying sandbody reservoirs were regarded as NW-SE distribution. It is shown that the Fault Liaoxi-1 with dextral strike-slip is comprised of connecting arcuate faults so that the distribution of reservoirs is controlled by the structural transfer zone. This cognition is supported by seismic attributes and heavy minerals analysis. The plots of sedimentary system that are re-established by major oil formation groups have demonstrated the reservoirs with NE-NNE distribution in this oil field. This recognition is significant for reservoir elaboration, flood-out rule analysis and remaining-oil development.更多还原
