| 中文摘要: |
| 阜康凹陷为准噶尔盆地富烃凹陷之一，其北部斜坡带为有利油气聚集区，早侏罗统三工河组发育辫状河三角洲，因其储集砂体面积大、厚度大受到较大关注。由于油气仍有较大挖掘潜力，同时油井水驱效果逐渐变差等问题逐渐显现，需要对研究区三工河组储层非均质性进行综合研究。利用岩心、录井、测井和地震资料，通过层内、层间和平面非均质性的详细研究，发现三工河组储集层的宏观非均质性很强，三工河组二段最强。利用压汞、核磁共振、恒速压汞、粒度、薄片分析和扫描电镜等资料，通过对三工河组储集层的孔喉、颗粒以及填隙物非均质性进行详细研究，发现三工河组储集层的微观非均质性很强。储集层非均质性受控于沉积背景、成岩作用和异常压力，综合认为三二段相较于三一段更有利于成藏。 |

| The Fukang sag is abundant in hydrocarbon in Junggar Basin, the north of which is a favorable block for oil and gas accumulation. The Sangonghe Formation of Early Jurassic hosts braided river delta, which receives much attention for large area and thickness of reservoir sand. Because of great potential of exploration as well as the water-flooding effect in oil wells getting worse gradually, comprehensive research is required on reservoir heterogeneity of the Sangonghe Formation in the slope area. This work made a detailed study on interbedded, intraformational and planar heterogeneity using cores, well logging, logging and seismic data. The results show that the whole Sangonghe Formation has strong macroscopic heterogeneity, especially its second member. Its microscopic heterogeneity is also revealed by analyses of pore throats, grains, mercury injection, nuclear magnetism, rate-controlled mercury penetration, SEM, and microscope images. Such reservoir heterogeneity was controlled by sedimentary background, diagenesis and abnormal pressure, and the second member of the Sangonghe Formation is more favorable for reservoir generation with respect to the first member. |
