Problems solved by technology
If conventional test methods are used to determine the effect of different temperature fractions on reducing the ignition temperature of heavy oil, it takes 3 3 (Considering 3 levels) tests, that is, 27 tests, the workload is huge, and the workload of data processing in the later period is also huge, and the regularity analysis of the data cannot be carried out, so it has little effect on the guidance of the later fire drive ignition process
[0003] For this, an effective method has not yet been proposed

Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the accompanying drawings in the embodiments of the application. Apparently, the described embodiments are only part of the embodiments of the application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the scope of protection of this application.
[0041] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purpos...

The invention provides a method and devices for analyzing influence of different temperature fractions on heavy oil ignition. The method includes the following steps: obtaining data of different temperature fraction content; obtaining the ignition temperature of heavy oil under each data according to the data of the different temperature fraction content; determining the numerical values of the heavy oil ignition influencing factors of different temperature fractions according to a first predetermined rule based on the ignition temperature of the heavy oil under each data; and performing ordering analysis on the different temperature fractions according to a second predetermined rule and the numerical values of the heavy oil ignition influencing factors of the different temperature fractions. The method and devices can ensure the influence degrees and influence ordering of the different temperature fractions during heavy oil ignition, so that technical guidance can be provided to enhance ignition effects of ignition operation; and main layers can be determined on site according to this or profile control measures can be determined on site according to this, and technical supports can also be provided to enhance ordinary heavy oil air flooding effects.
Description
technical field [0001] The application belongs to the technical field of petroleum exploitation, and in particular relates to a method and a device for analyzing the influence of different temperature fractions on the ignition of heavy oil. Background technique [0002] During the ignition process of heavy oil fire flooding, crude oil fractions at different temperatures in the reservoir have different effects on the ignition temperature of crude oil. If conventional test methods are used to determine the effect of different temperature fractions on reducing the ignition temperature of heavy oil, it takes 3 3 (Considering 3 levels) tests, that is, 27 tests, the workload is huge, and the data processing workload in the later stage is also huge, and the regularity analysis of the data cannot be performed, so it has little effect on the guidance of the later fire drive ignition process. [0003] For this, an effective method has not yet been proposed. Contents of the inventio...
