Abstract

The invention relates to an energy-releasing composite preparation and a preparation method thereof, belonging to perforating slurry for oilfield exploitation. The energy-releasing composite preparation is prepared by mixing the following components in parts by weight: 41-53 parts of an adhesive, 40-60 parts of a combustion agent, 5-15 parts of a functional additive, 8-10 parts of an accelerant, 1-3 parts of a curing agent and 5-7 parts of a crack proppant. A combination of the prepared slurry and perforating bullets can reduce a perforation skin coefficient by 10%, and plays a good role in reducing water injection pressure and increasing output in domestic low-permeability oil and gas reservoirs such as Yanchang Oilfield and Changqing Oilfield. The average penetration depth of a perforator assembled with the slurry is 825 mm while the average penetration depth of a perforator without the slurry is 785 mm, so the penetration depth is improved by 5.1% and an aperture is increased by 6.1%. The produced slurry is made of inert materials, has no risk in production and assembly, is safe and reliable, and belongs to energy-releasing products. The produced slurry meets technical requirements, has an explosion heat test value of no less than 2600 kJ / kg, can resist a temperature of 180 DEG C for 48h, and is free of rheological phenomenon and spontaneous combustion.

Description

technical field [0001] The invention relates to a perforating slurry for oil field development, in particular to an energy-releasing composite preparation and a preparation method thereof. Background technique [0002] With the continuous exploitation of oilfields, the perforating technology for oilfield exploitation is also developing continuously. The currently used perforating slurry is mostly composite propellant or low-detonation velocity explosive, which has a good perforating effect, but is extremely dangerous and belongs to dangerous explosives. Once an accident occurs, it will endanger life. Therefore, it is urgent to develop a new perforation product with strong safety, which can ensure the production rate while ensuring the perforation depth and aperture. Contents of the invention [0003] The object of the present invention is to provide an energy-releasing compound preparation and a preparation method thereof in order to overcome the shortcomings of the above...
