Abstract

The invention belongs to an underground chemical igniter in an oil field fire-flooding explosion oil layer, and particularly relates to a preparation method of a fire-flooding particle igniter. According to the preparation method of the fire-flooding particle igniter, an inflammable compound, an oxidant, a catalysis activating agent and highly-alloyed powder particles are used as raw materials. The preparation method is characterized in that the formula comprises 12% of the inflammable compound, 1.5% of the oxidant, 35% of the catalysis activating agent and 51.5% of the highly-alloyed powder particles, wherein the oxidant is potassium nitrate, and the catalysis activating agent is ferrous chloride. The preparation method has the beneficial effects that the oil layer can be ignited safely when the oil layer is at the temperature of 180 DEG C, and the fire-flooding particle igniter has the characteristics of low ignition point, high combustion temperature and stable combustion.

Description

technical field [0001] The invention belongs to an underground chemical igniter of an oil field fire drive recovery oil layer, and in particular relates to a preparation method of a fire drive powder igniter. Background technique [0002] At present, ignition technology is the key to oil recovery by fire flooding in oilfields. Safe and effective ignition and continuous and stable combustion directly affect the success of oil recovery by fire flooding. Oilfield fire flooding tests include chemical ignition, steam preheated spontaneous ignition and electric ignition, but The success rate is not high. Contents of the invention [0003] In order to overcome the above problems, the present invention provides a method for preparing a fire-displacement powder igniter. The fire-displacement powder igniter preparation method is to use flammable agents, oxidizers, catalytic activators, and high-alloy powders as raw materials, wherein, The oxidizing agent is potassium nitrate, and t...
