压裂水平对致密气藏开采的影响及优化研究

摘要

Due to different reservoir properties of gas reservoirs in different regions of the gas layer, production methods and percolation mechanism are also very different. In this paper, taking tight gas reservoirs as the object of study, impact of fracturing level on the production was investigated, and optimization programs were put forward. Using Eastern Sulige gas reservoir as an example, in-depth research and analysis of the various parameters were carried out, and then optimization measures were designed. Through the research, it’s pointed out that the permeability and other properties of the formation can affect drainage capacity of fractures in horizontal wells.%由于不同气藏地区的储气层的储物性不同，因而开采方式及渗流机理也存在很大的差异。以致密气藏为研究对象，主要研究压裂水平对其排采的影响，并提出优化方案，以苏里格东区气藏为例，深入研究和分析其各种参数，并以此为基础设计优化措施。可以看出，地层的渗透率及其各向性能都能影响压裂裂缝的在水平井中的排采能力，压裂水平对致密气藏开采的影响及对开采进行优化对未来致密气藏的开采起着重要的意义。
