Parameter.
In the above-described embodiment, it to determine crude oil ignition parameter, first has to test according to temperature using boiling range to original
Oil is distilled.It should be noted that the crude oil ignition parameter can be the ignition delay time of crude oil, or it can be crude oil
Firing temperature.
Specifically, it can use boiling range test to cut crude oil, crude oil be divided into less than 250 DEG C, 250 DEG C -300
DEG C, 300 DEG C -350 DEG C, and it is greater than 350 DEG C, then four temperature range sections obtain this four temperature range section crude oil fractions
The data of content, the data finally based on this four temperature range section crude oil fractions contents, are calculated the original according to formula
Oily ignition parameter.Wherein the formula of determining crude oil ignition parameter is：
Wherein, t is crude oil ignition parameter；σ is crude oil igniting empirical value；AiCrude oil fractions for i-th of temperature range contain
The data of amount, i take 1 to take positive integer into n.
It is possible to further determine crude oil igniting empirical value in accordance with the following methods：
Multiple groups crude oil sample can be picked up first, for the accuracy of the crude oil igniting empirical value acquired, can be picked up to the greatest extent
The more crude oil sample of amount.But as an example, 3 groups of crude oil samples are only chosen in following embodiments.
Then burnt respectively using spontaneous combustion experimental tests to every group of crude oil sample, obtain after the burning of every group of crude oil sample
The crude oil of different temperatures segment (less than 250 DEG C, 250 DEG C -300 DEG C, 300 DEG C -350 DEG C, and being greater than 350 DEG C), which is lighted a fire, joins
Number；
Finally can crude oil ignition parameter averaged to each group crude oil sample in same temperature section, the average value
As crude oil igniting empirical value.
A specific embodiment is given in the present invention to be illustrated the method for above-mentioned determining crude oil ignition parameter.
It should be noted, however, that the specific implementation merely to the present invention is better described, is not constituted to improper limit of the invention
It is fixed.
In this example, this method includes：
Step 1,3 groups of crude oil samples are chosen, self-ignition point combustion test are carried out respectively to this 3 groups of crude oil samples, what is obtained is every
Crude oil ignition parameter after group crude oil sample burning in different temperatures segment is as shown in table 1：
Table 1
Step 2, to above-mentioned 3 groups of crude oil samples same temperature segment crude oil ignition parameter averaged.Because
Crude oil ignition parameter includes ignition delay time and firing temperature, thus it is following when seeking crude oil ignition parameter average value, to divide
It is other to ignition delay time and firing temperature averaged.
Wherein, the average value finding process of ignition delay time is as follows：
Less than 250 DEG C (<250 DEG C) temperature range section seek ignition delay time average value be (13.53+
13.30)/2=13.42；
It is (13.63+13.83+ in the average value that 250 DEG C -300 DEG C of temperature range sections seek ignition delay time
12.93)/3=13.46；
It is (14.73+15.20+ in the average value that 300 DEG C -350 DEG C of temperature range sections seek ignition delay time
13.50)/3=14.48；
It is (17.03+ in the average value that the temperature range section greater than 350 DEG C (350 DEG C of >) seeks ignition delay time
16.83+17.17)/3=17.01；
Wherein, the average value finding process of firing temperature is as follows：
Less than 250 DEG C (<250 DEG C) temperature range section seek firing temperature average value be (215.40+215.20)/
2=215.30；
It is (220.10+221.50+ in the average value that 250 DEG C -300 DEG C of temperature range sections seek firing temperature
193.60)/3=211.73；
It is (238.80+249.80+ in the average value that 300 DEG C -350 DEG C of temperature range sections seek firing temperature
206.60)/3=231.73；
It is (274.40+267.30+ in the average value that the temperature range section greater than 350 DEG C (350 DEG C of >) seeks firing temperature
280.20)/3=273.97；
It should be noted that the crude oil igniting empirical value (empirical value and igniting temperature of ignition delay time sought herein
The empirical value of degree) by the definite value of test sample determination, it can directly be utilized when seeking crude oil ignition parameter.
Step 3, using boiling range test according to temperature range section (less than 250 DEG C, 250 DEG C -300 DEG C, 300 DEG C -350 DEG C, with
And it is greater than 350 DEG C) crude oil is distilled, then data of available crude oil fractions content.
For example, crude oil less than 250 DEG C (<250 DEG C) temperature range section ends content be 10.98%；
It is 5.84% in 250 DEG C -300 DEG C of temperature range section ends contents；
It is 20.72% in 300 DEG C -350 DEG C of temperature range section ends contents；
It is being 62.49% in the temperature range section ends content greater than 350 DEG C (350 DEG C of >).
Step 4, the data of the crude oil igniting empirical value in step 2 and the crude oil fractions content in step 3 are brought into formula
In；
Wherein, t is crude oil ignition parameter；σ is crude oil igniting empirical value；AiCrude oil fractions for i-th of temperature range contain
The data of amount, i take 1 positive integer into n.Because being divided into four temperature range sections (less than 250 DEG C, 250 DEG C -300 DEG C, 300
DEG C -350 DEG C, and it is greater than 350 DEG C), therefore n=4 herein；I can be with value 1,2,3,4.
Then available crude oil ignition delay time is：td=13.42 × 10.98%+13.46 × 5.84%+14.48
× 20.72%+17.01 × 62.46%=15.88min
The firing temperature that can also obtain crude oil is：ti=215.3 × 10.98%+211.73 × 5.84%+231.73 ×
20.72%+273.97 × 62.46%=255.14 DEG C
In order to verify the accuracy that the crude oil ignition parameter determines method, the above results and the igniting of practical crude oil can be prolonged
Slow time td=16.23min and firing temperature ti=259.40 DEG C compare, and respectively obtain the standard of crude oil ignition delay time
Really rate is：97.843%；The accuracy rate of crude oil firing temperature is：98.358%.
It is determined it can be seen that can use simple boiling range test using the method for the determination crude oil ignition parameter of the application
The ends content of different temperatures segment calculates crude oil ignition parameter (crude oil ignition delay time and crude oil point using formula
Fiery temperature) accuracy rate with higher, it can be implemented at crude oil fireflood igniting scene.
