复杂底水型气藏储层发育控制因素及气水分布模式--以四川盆地龙岗礁滩型碳酸盐岩气藏为例
Study on the controlling factors of reservoir development and gas/water distribution pattern of complex gas reservoir with bottom water：A case study in Longgang reef lfat carbonate gas ifeld, Sichuan Basin
摘要
Abstract
Controlled by the deposition and diagenesis, the reservoir heterogeneity of carbonate gas reservoir is serious and the gas water distribution is also complex. This ifeld shows scattered bottom water characteristics. The paper takes the Longgang gas reservoir as an example to analyses the controlling factors of reservoir development, gas water distribution and gas well development characteristics. Results showed the ifeld of Longgang is controlled by sedimentary facies, dolomitization, dissolution and fracture. The favorable sedimentary facies is the material basis in the development of reservoir. The dolomitization is a plus factor. The dissolution is a key factor and the fracture is an effective way to increase permeability. Gas water analysis indicated Longgang gas reservoir hadfour gas water distribution patterns which included thin formation edge water, thick massive bottom water and layered gas reservoir. Gas water distribution and enrichment regulation were controlled by structure, reservoir permeability body morphology, physical properties, fracture, the tight layer updip direction of reservoir permeability body, and the degree of gas supply in the process of gas accumulation. The wells which have different gas water distribution pattern have different development characteristics. According to these characteristics, we can make the development strategies so as to improve the effect of gas reservoir development.关键词
