The utility model, which is the core of a a physical simulation device for in-situ combustion, has the characteristics of a real combustion process of simulation strata, heat transfer conditions of the simulation strata and the uniform propulsion of a fire front edge. The utility model is used in the in-situ combustion production practice.
Description
One, technical field
The utility model relates to petroleum thermal recovery combustion (of oil) in site process unit, relates in particular to a kind of combustion (of oil) in site physical simulating device firing chamber.
Two, background technology
Present combustion (of oil) in site physical simulating device firing chamber of using, generally adopt the metal basket, because the metal heat-conducting coefficient is far longer than the rock core coefficient of heat conductivity, adopt such physical model to carry out indoor combustion (of oil) in site experiment, be easy to cause that heat preferentially transmits along the rock core tube wall in the ignition process, thereby make the combustion process distortion.In experiment, such basket the rock core coking also repeatedly occurs near the metal pipe-wall and causes the coke zone permeability phenomenon that significantly descends, because the preferential heat conduction of metal and the decline of core permeability often make experimental result lack authenticity.
Three, summary of the invention
The technical matters that the utility model solves provides a kind of improved combustion (of oil) in site physical simulating device firing chamber, it can solve above-mentioned problems of the prior art effectively, can the true combustion process of simulated formation, avoid that heat preferentially transmits along the rock core tube wall in the ignition process, cause the rock core tube wall coking phenomenon to occur; The coefficient of heat conductivity of described basket coefficient of heat conductivity and understressed sand is close, eliminates the influence of radial and axial strong heat conduction, the simulated formation heat transfer condition, and cross-section temperature field evenly distributes; Described temp measuring system is characterized in that thermopair is evenly distributed on inner 13 of basket vertically, can monitor the basket inside temperature variation of diverse location vertically.
Combustion (of oil) in site physical simulating device described in the utility model firing chamber, comprise shell, basket, rock core seat, temp measuring system and lighter, the temp measuring system thermopair of basket of installing in the described shell and interior axial distribution thereof, the lighter that rock core seat of installing under the shell and cover top portion are installed.
Wherein, described temp measuring system comprises 4～20 temperature sensors of axially installing the thermopair in basket and being electrically connected with it.Described basket is the tubular structure that nonmetallic materials such as pottery or aluminium oxide ceramics are made, and Qi Bishang is provided with the side opening of installing thermopair.
The utility model has following advantage compared with prior art:
1, the basket material is nonmetal as pottery or aluminium oxide ceramics, and the coefficient of heat conductivity of coefficient of heat conductivity and understressed sand is close, eliminates the influence of radial and axial strong heat conduction, the simulated formation heat transfer condition, and cross-section temperature field evenly distributes.
2, temp measuring system can be described the Temperature Distribution of whole core axis to diverse location, has realized burning the detailed description of temperature in the frontal movement process.
3, the true combustion process in experimentation analogue simulation stratum, data are accurate.
