Description
Technical field
The present invention relates to the exploitation method of a kind of viscous crude and super-heavy oil deposit, particularly a kind of for the viscous crude of buried depth more than 1000 meters and the underground hydrogenation catalyst method for modifying of super-heavy oil deposit, belong to technical field of petroleum extraction.
Background technology
Viscous crude and super-heavy oil deposit adopt steam injection development usually, but buried depth is greater than to the heavy crude reservoir of 1000 meters, although employing insulated tubing, but because steam is larger along journey steam quality loss, for guaranteeing that there is certain steam quality in shaft bottom, need the steam injecting high mass dryness fraction at well head, the energy consumption of therefore exploiting is comparatively large, and exploiting economy benefit is poor.
The heavy crude reservoir of 1000 meters is greater than, in extraction process, because the temperature from shaft bottom to well head reduces gradually for buried depth, viscosity of thickened oil sharply raises, and condenses on internal surface of sleeve pipe, causes oil pumper extraction difficult, pump efficiency is lower, often needs wellbore heating or mixes rare exploitation.It can thus be appreciated that, seek a kind of exploitation method that significantly can reduce viscosity of crude, can effectively improve producing well pump efficiency and output.
Viscosity reduction mode for viscous crude comprises physics viscosity reduction and chemical modification viscosity reduction.Physics viscosity reduction comprises high-temperature heating viscosity reduction, injects the modes such as the molten oily viscosity reduction of solvent, and because viscous crude molecular structure after physics viscosity reduction does not change, extraction ground still needs high temperature refinery.For chemical modification viscosity reduction, generally include high temperature water thermal cracking and high temperature situ combustion technology.
High temperature water thermal cracking occurs in injection steam course, and early stage, a large amount of report showed, hydrothermal cracking upgrading effect is poor, and strand restructuring and condensation reaction will occur the viscous crude of viscosity reduction after temperature reduces, and viscosity of crude can rebound.
Situ combustion technology is the irreversible viscosity reduction technology of viscous crude, but application number is 201210587241.1 application discloses " in a kind of oil underground low temperature controlled catalytic oxidation upgrading exploitation method ", it points out that combustion in situ has following deficiency: the carrying out of (1) system reaction and the heat of generation are determined by oxygen concentration, cannot realize controlling comparatively accurately; (2) system temperature is too high, in field use, often reach more than 600 DEG C, and when in fact viscous crude is below 200 DEG C, mobility is greatly improved, Pintsch process also mostly can occur below 500 DEG C, the grade of heat too high certainly will needs consumes more fuel, affects recovery ratio; (3) coking phenomenon is obvious, and the high-temperature area of edge front adjacent forms wider coke zone before combustion, not only affects the propelling of combustion front and the diabatic process of system, also causes destruction to a certain degree to oil reservoir.
Low temperature controlled catalytic oxidation upgrading exploitation method in a kind of oil underground is provided in said method, the method comprises the following steps: the oil reservoir near heating Injection Well makes its temperature be elevated to 100-400 DEG C, inject oxygen-containing gas, heat-dissipating catalyzer and modifying catalyst, under heat-dissipating catalyst action, oxygen-containing gas and part oil reservoir generation catalytic oxidation, make crude oil by heating, viscosity reducing; Modifying catalyst catalysis crude oil upgrading, the crude oil after upgrading is by producing well extraction.Said method has following effect: utilize the oxidation reaction liberated heat of part oil reservoir from heat supply, greatly reduce the radiation energy consumption of external heat source in transport process; Flow at heating in crude oil in the process of producing well and carry out degree of depth upgrading and fall glutinous, be conducive to the further raising of crude quality, meet the requirement that exploitation is defeated with collection.
Application number be 201210586830.8 patent application provide the method for the controlled Self-heating of low temperature under a kind of viscous crude and super-heavy oil deposit condition.The method comprises the following steps: in oil reservoir, inject oxygen-containing gas and catalyzer by the Injection Well of viscous crude or super-heavy oil deposit; Oil reservoir near heating Injection Well carries out heating makes its temperature be increased to 100-400 DEG C, starts catalytic oxidation exothermic reaction, and reaction liberated heat heating oil reservoir, realizes the controlled Self-heating for viscous crude or super-heavy oil deposit.Said method has following beneficial effect: (1) achieves the controlled Self-heating process of oil reservoir inside, decreases fuel consumption, reduces process energy consumption; (2) can the excessive temperature rise process of the hierarchy of control, there is no coking district between reaction costal field and condensing zone, be conducive to reaction leading edge and push ahead, expand swept volume, improve oil production rate.
But there is the problem of the following aspects in said method: (1) does not provide the injection technique strategy of heat-dissipating catalyzer and modifying catalyst.Catalyzer is solid phase fine particle, and be difficult to be uniformly distributed at injection oxygen-containing gas, when not having carrier solution of good performance, gas is difficult to carry solid-phase catalyst and enters oil reservoir; (2) the catalyzer technological approaches that how to realize fully contacting with oil reservoir is indefinite.Under high velocity air injection condition, sub-fraction in solid-phase catalyst can enter oil reservoir along macropore or high permeable strip, but be only limitted to macropore and high permeable strip, catalyzer is difficult to evenly to enter oil reservoir deep and especially realizes catalytic reforming on a large scale in hyposmosis region, and upgrading effect is very limited; (3) replacement problem after catalyst failure.Due to catalyst failure (being commonly called as: catalyst poisoning) will be there is in catalyzer and viscous crude contact process, how catalyzer after inefficacy discharges, how new catalyzer is filled up or is supplemented, the catalyzer how new catalyzer crosses inefficacy enters new oil reservoir region, whether can there is a certain regional area and repeat the problems such as catalysis.
In sum, the viscosity reduction technique proposing a kind of effective viscous crude and super-viscous oil in order to the deficiency of the viscosity reduction mode of existing viscous crude becomes a kind of needs.
