摘要: 苏里格气田某井区作为本区块水平井整体开发试验区,实施38口水平井2年建成10亿方产能,开发效果显著,对本区的精细地质研究已形成了一套行之有效的研究思路和方法。通过针对区块低孔、特低渗,发育河流相砂体的储层特点,综合各种静态资料,建立精细气藏三维可视化地质模型,刻画了本区河道砂体展布,为水平井整体开发和水平井地质跟踪实施提供了地质保障,同时研究得出的区块剩余气分布规律,为水平井分步实施提供了依据;对水平井整体开发的各部署参数的合理取值进行了研究,在利用非结构网格刻画压裂水平井地层裂缝系统的基础上,通过气藏数值模拟对水平井井网井距等部署参数的优化论证,得出适合的参数值,结果表明本研究可对气田的整体开发提供指导,效果显著,同时为同类气藏的研究提供了有利的借鉴。

Abstract: A borefild in Sulige gas field, as the development experimental zone of this block, has built 1 billion square production after more than two years' pilot development. In this area, a set of effective thinking and method of research has formed about the fine geologic research. On the one hand, according to the characteristics of low porosity, low permeability and fluvial facies sand body developed, synthesizing all kinds of static and dynamic development data. The fine reservoir 3D visualized geological model was established and the areal channel sand body distribution was carved, which provide geological guarantee for the overall development of horizontal well and horizontal well geologic trace and implementation. Meanwhile, the regional distribution rule of remaining gas was gained, providing the reference for implementing horizontal wells step by step. On the other hand, based on unstructured grid used for depicting fracture system, through the gas reservoir numerical simulation, deployment parameters of horizontal well pattern, well spacing etc., are optimized and demonstrated, and reasonable values of parameters are gained, which provides reference to similar other fields for overall development.
