Abstract

The invention provides a high-performance ignition agent for oilfield exploitation and a preparation method of the high-performance ignition agent. The ignition agent comprises the following components in parts by weight: 30-70 parts of matrix fuel, 1-4 parts of an oxidant, 2-4 parts of a combustion improver, 2-6 parts of a catalyst and 1-3 parts of a stabilizer. The preparation method comprises the following steps: mixing a matrix fuel and an oxidant in a reaction kettle, and stirring the raw materials to obtain a mixture; adding a combustion improver, a catalyst and a stabilizer into the mixture, vacuumizing the system, and stirring the mixture to obtain the high-performance ignition agent for oilfield exploitation. The ignition agent is easily available in raw materials, low in price, simple in process and beneficial to large-scale popularization and utilization. The ignition agent only needs very low energy to ignite, is sufficient in combustion and high in combustion performance,so that the ignition success rate is increased, a large amount of energy can be saved, and the environmental protection requirement is met. The application range of the ignition agent in oil exploitation is widened.

Description

technical field [0001] The invention belongs to the technical field of oil field recovery, and in particular relates to a high-performance igniter for oil field development and a preparation method thereof. Background technique [0002] Oil extraction refers to the behavior of digging and extracting oil in places where oil is stored. During the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. Ignition is the most important step in the process of burning oil reservoirs. Common ignition methods include electric ignition and chemical ignition. The ignition process has disadvantages such as complexity, difficult operation, and low performance. It is urgent to find an ignition agent suitable for oil exploitation. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a high-performance igniter for oil field development. [0004] Th...
