摘要:
鄂尔多斯盆地米脂气田太原组砂岩是致密气藏的主力产层,但砂体横向变化快。研究表明:古地貌是控制砂体沉积的重要因素,决定着砂体发育位置及分布规模。基于三维地震资料,结合完钻井数据,运用印模法与沉积学综合分析相结合的方法,采用三维地震地层水平切片、多属性融合技术,通过沉积厚度求取,恢复米脂气田二叠系太原组沉积期的古地貌,分析古地貌对三角洲前缘砂体及油气的控制作用,进而通过地震属性和神经网络技术预测太原组有利砂带的分布规律。研究成果优化井位部署,新井钻遇太原组砂岩的符合率达到90%,进一步证实了基于古地貌的储层预测技术的可靠性,对米脂气田的效益开发具有重要的指导意义。
Abstract:
The sandstone of the Taiyuan Formation in the Mizhi Gasfield of Ordos Basin is the main producing layer of tight gas reservoir,but the transverse change of sand body is fast. The results show that paleogeomorphology is a critical factor controlling the deposition of sand bodies,which determines the development location and distribution scale of sand bodies. Based on 3D seismic data,combined with drilling data,using the method of combining the impression method with sedimentology comprehensive analysis,3D seismic stratum horizontal slice and multi-attribute fusion technology are used to obtain the sedimentary thickness to restore the paleogeomorphology of Permian Taiyuan Formation in Mizhi Gasfield during the sedimentary period,and analyze the control effect of paleogeomorphology on the sand body and hydrocarbon of the front edge of the delta. Then the distribution of favorable sand zones in the Taiyuan Formation is predicted using seismic attributes and neural network technology. The coincidence rate of the new well drilling into the sandstone of the Taiyuan Formation is 90%,the research results further confirm the reliability of the reservoir prediction technology based on paleogeomorphology,which has important guiding significance for the beneficial development of Mizhi Gasfield.
