摘　　要：王窑地区长611地层为三角洲前缘沉积,主要沉积微相为三角洲前缘水下分流河道、河道侧缘砂、分流河口砂坝、前缘砂席和分流间湾等。根据岩心描述结果和测井曲线,结合砂体形态对长611油层三角洲沉积微相和砂体展布进行综合表述,并提出开发调整意见。The origins of Chang-61^1 reservoir horizonsin Wangyao district of Ansal Olltleld are lnterpretea to be a delta deposited in lacustrin environment. The mains edimentary microfacies of Chang-61^1 reservoir horizons in Wangyao district include distributary channel, river＇s side sandsheet distributary mouthbar, sandsheet and inter distributary deposits. The deltaic microfacies are interpreted and delineated based on depositional sequence, log curves and sandbody geometry. Comprehensived escriptions of sedimentary microfacies and the distribution of sandbody are good methods to predict reservoir performance.
