随着几年石油天然气的发展,带动了各行各业的发展和进步,天然气领域在其中起到了重要作用。其中我国的西气东输工程就是一个很好的例子和创新突破,在西气东输中的苏里格气田就起到了至关重要的作用,它是主力气源地。苏里格大气田的发现,为进一步扩大向北京、天津以及整个华北地区、东部地区、陕甘宁地区和中原地区的天然气供应,奠定了可靠的资源基础。由于苏里格气田是罕见的“三低”气田(低渗、低压、低丰度)气田,储层致密、薄而分散,储层非均质性强,单井控制储量小;稳产期短,平均单井采出量小。开发难度在世界上独一无二。所以在油气田的开发上对我国天然气企业来说是一次挑战和攻克性的难题。本文谈论了苏里格气田南区气藏储层特征并对其进行了评价和研究这对于天然气企业是一个指导是一个理论根据。
With the development of several years of oil and natural gas and the development and progress of all walks of life, the field of natural gas has played an important role in it. Among them, China’s West-East Gas Pipeline project is a good example and a breakthrough in innovation. It plays a crucial role in the Sulige gas field in the west-east gas transmission and is the main gas source. The discovery of the Sulige Gas Field has laid a solid foundation for further expanding the supply of natural gas to Beijing, Tianjin, the entire North China region, the eastern region, the Shaanxi-Gansu-Ningxia region and the Central Plains region. Because the Sulige gas field is a rare gas field with low permeability, low pressure and low abundance, the reservoirs are dense, thin and dispersed with strong reservoir heterogeneity and small single-well controlled reserves. Stable production Short period, the average single well recovery is small. The difficulty of development is unique in the world. Therefore, in the development of oil and gas fields for China’s natural gas enterprises is a challenge and overcome the problem. This article discusses the characteristics of the gas reservoirs in the southern area of the Sulige gas field and evaluates and studies them. This is a theoretical basis for the guidance of natural gas enterprises.
