| 中文摘要: |
| 研究区位于松辽盆地大庆长垣以东地区安达凹陷北部,由于该地区勘探程度较低、钻井数量较少,造成了该区块油气地质方面的研究水平相对较低。为了落实对该区块下一步勘探目标,通过对沉积相分析、测井相分析、地震属性预测以及井震结合等技术方法,精确识别研究区扶余油层的沉积微相类型及其特征研究,认为该区发育2种亚相6种微相。在沉积微相横向与纵向展布规律的基础上,充分应用地震属性预测技术,实现了沉积微相平面展布规律的精确刻画,为储层砂体预测及勘探有利区优选奠定了良好的基础。 |
| 英文摘要: |
| The study area is located in the northern part of the Anda Depression, east of the Daqing Placanticline. Due to the low exploration level and the small number of drilling in this area, the research level of oil and gas geology in this block is relatively low. In order to implement the next exploration target of the block, this study accurately identified the types and characteristics of sedimentary microfacies in the Fuyu oil layer in the study area through sedimentary facies analysis, well logging facies analysis, seismic attribute prediction, and well-seismic combination. It is believed that there are 2 subfacies and 6 microfacies in this area. On the basis of the horizontal and vertical distribution of sedimentary microfacies, the seismic attribute prediction technology is fully applied to achieve the accurate description of the planar distribution of sedimentary microfacies, which lays a good study for the prediction of reservoir sand bodies and the selection of favorable exploration areas basis. |
