| 摘 要： | 通过岩心观察、大量测井及相关测试资料分析统计,确定了大路沟二区长61油层的沉积类型为三角洲前缘亚相沉积,主要发育水下分流河道、河道侧翼、分流间湾及河口砂坝四种微相,分析了各种沉积微相的特征.研究表明水下分流河道微相是长61油层的主要沉积微相,水下分流河道砂为储集层骨架砂体.同时对长61油层各小层的沉积微相平面展布和砂体展布特点进行了分析,认为油气的聚集主要受沉积微相的控制,水下分流河道为长61油层良好的储集层,是研究区油气开发的方向 |

| Abstract: | According to the core observation,a large number of logging and relevant test material analysis,the sedimentary facies were determined to be the front-delta deposition.Four microfacies types were recognized including subaqueous distributary channel,sidewing of distributary ehannel,mouth-bar,subaqueous interdistributary embayment,analyzed the various characteristics of sedimentary microfacies.Research shows that the subaqueous distributary channel is the primarily microfacie of the Chang 61 reservoir and the distributary channel deposits is the main reservoir sands.The evolution and the distribution of the microfacies and sand body exhibition in every number have been studied,the accumulation of oil and gas are controlled by microfacies,the distributary channel deposit of Chang 61 is the good reservoir,and also is the direction of the developing in Jing’an oil field. |
