Description
Technical field
The present invention relates to petroleum works and technology field, be specifically related to a kind of for in-situ combustion heavy oil recovery pitch oil reservoir physical simulation experiment device.
Background technology
Combustion in situ is one of important method improving oil recovery factor, belongs to heating exploitation technology.It utilizes the part pyrolysis product of oil reservoir itself to make fuel, heat-dissipating of constantly burning, and relies on the effect of heating power and other comprehensive driving force, realizes the object improving recovery ratio.Combustion in situ is conceived to be the oil recovery factor improving heavy crude reservoir at first.The method not only for improving viscous crude, oil-sand, pitch oil recovery, and is applicable to middle matter and light oil reservoirs crude oil production.
Situ combustion technology originates from 1911, and formally propose as far back as J.O. Levi's in 1917 method adopting heating power or note solvent, the crude oil in displacement stratum is to improve the concept of recovery ratio.
Nineteen twenty-three, Wolcott and Howard also recognized, air Injection to oil reservoir, made oil reservoir be burn a part of crude oil in the key of underground combustion process, produced heat to reduce viscosity, produced the driving force of displace crude oil simultaneously.Their this understanding has applied for United States Patent (USP) in nineteen twenty-three.Nineteen forty-seven starts laboratory in-house laboratory investigation.After entering the 1950's, the petroleum resources of the U.S. are day by day exhausted, and find exploration success ratio reduces, and this new technology is just paid close attention to widely.From nineteen fifty-one, each oil company expands a series of experimental study in oil field, situ combustion technology is obtained and develops fast.
A combustion in situ field trial is the earliest carried out in the Bert Le Siweier oil field of the U.S. Oklahoma nineteen forty-two in the world.After the fifties, according to statistics, the U.S. has carried out more than 70 combustion in situ project.More than 40 countries such as the former Soviet Union, Holland, Romania, Hungary, Germany, India are also had successively to carry out the related work of combustion in situ oil recovery in addition.
China was from 1958, successively in Xinjiang, Yumen, triumph, the oil field such as Jilin and the Liaohe River carried out combustion in situ experimental study, because of the restriction by prevailing condition, situ combustion technology makes way for steam injection recovery, in the application of the scene of China until also few in number at present.
For steam injection recovery, though combustion in situ oil-extraction method complex process, technical condition require harsher, show its distinctive superiority: (1) combustion in situ oil-extraction method has oil displacement efficiency high (generally reaching 80% ~ 90%); (2) oil reservoir wide accommodation (from oil sheet to thick oil pay, from shallow oil reservoir to deep fat, from thin oil to viscous crude, and developing oil reservoir); (3) injectant-air that it uses grows on trees; (4) what combustion in situ was burnt is in crude oil about 10% heavy constituent, improve residue oil properties; (5) heat of combustion in situ produces on the spot, higher than the heat utilization rate of steam injection, and can save the investment of ground and thermally insulating the borehole measure.
Because combustion in situ is a kind of oil production method with obvious technical advantage and potentiality, there is oil reservoir wide accommodation, thing source is sufficient, recovery ratio is high, cost is low advantage.But because combustion in situ mechanism is very complicated, also there is a lot of problem in the design of combustion in situ reservoir engineering and mining site dynamic management, particularly the burning occurred in reservoir and oil displacement process are lacked and be intuitively familiar with accurately, be difficult to take effective means accurately to judge underground combustion situation, monitor and forecast combustion in situ leading edge.In order to further investigate the inherent mechanism in oil layer ignition process, often will by laboratory physical simulation experiment device.The parameter such as unit volume oil-sand sedimentation of fuel amount, unit volume oil-sand oxygen demand, air/oil ratio in combustion in situ oil displacement efficiency and combustion process can be obtained by one-dimensional physical model experimental facilities, also data fltting speed, high-temperature oxydation (burning) reactive kinetics parameters of different combustion in situ stage burning band leading edge can be calculated by experiment, contrast experiment can also be carried out for responsive parameter such as gas injection speed, gas injection pressure, crude oil property, pore characteristics, optimize note and adopt parameter.
