The combustion characteristics of water-in-oil emulsion droplet and the effects of environment condition and contents of water in the emulsion on the micro-explosion are investigated by analyzing the heat and mass transport processes in the gas phase, the heating processes of droplet and the gasification of oil at the gas-liquid interface. The optimum conditions of micro-explosion are determined. Results show that the burning rates are increased due to micro-explosion of droplet, thus reducing total time of droplet burning. The adiabatic flame tempereture and the tempereture at the droplet surface are lowered because of the presence of water in the droplets. The liquid phase cracking reactions and the formations of earboneeous particules are suppressed. Both NOx and SOx emissions are reduced. It is further indicated that the rises in ambient tempereture and pressure and full-oxygen burning are of benefit to micro-explosion of the droplet. The certain difference of boiling point between oil and water is the necessary condition of micro-explosion. The suitable content of water in the emulsions is 10% wt to 30% wt.

在液体燃料中掺入一定量的水,制成乳状液,作为代用燃料,这种新技术正受到普遍重视。其优点是由于在一定条件下的“微爆”效应,将加快燃烧速度,减少总的燃烧时间,节省燃料,同时水起了部分的催化作用,能抑制碳颗粒的生成,减少NO_x和SO_x等在排气中含量。 实用的乳状液为油包水型(W/O型),即油是连续相,水是分散相,本文分析油包水型乳状液单滴在燃烧过程中气相的热量和质量输运、液滴的加热过程,研究了水含量和环境条件对微爆的影响,为使用乳状液提供合理的参数。

In this article,the effects of scaling factor ■ (the ratio of velocity in fractures to the imbibition velocity of the rock matrix) and w_g (the ratio of gravity to the driving force in fractures) upon the mechanism of imbibition in a medium with double porosity,are studied by numerical simulation.The most important factor affecting the displacement efficiency in rock matrix is ascertained,and the distribution limits of the region where the quasi-piston displacement of two phases in fractures takes place. In this paper,the general model is developed on the basis of identifying the condition necessary for the quasi-piston displacement of two phases in fractures.It is indicated for the first time,that in a bottom water drive carbonate oil reservoir the movement of oil and water interface can be expressed in the form of a linear integral equation,and can be solved analytically by integral transformation.The result obtained has been used in the Renqiu oil field. An expression describing the term representing the imbibition in rock matrix used in the numerical simulation model is formulated in the a more sound theoretical basis and to be calulated easily.
