Embodiment 1

[0035] Example 1: Well T**32, well depth 2342m, oil layer thickness 6.5m, oil layer position: 3512.2 ~ 3518.5m, belongs to the low permeability block, has been producing steadily after putting into production, but before the measures were reformed, the reserves dropped sharply, so After the implementation of particle beam perforation fracturing technology, the blockage near the wellbore was unblocked, and the daily liquid production was 20t / d, and the daily oil production was 12t / d. Compared with the original production of 5t / d, the production increase effect is very significant.

Embodiment 2

[0036] Example 2: Well XJ**3, well depth 3319 m, oil layer thickness 10m, oil layer position: 2834--2843m. sandstone. The original daily liquid production was 8t / d, and the daily oil production was 3.6t / d. Fracturing was carried out using a super-combustible particle beam micro-channel fracturing device, and the construction operation went smoothly. After the operation, the fracker was lifted out of the well without any damage. Put into operation, the daily liquid production reaches 30t / d, and the daily oil production reaches 15t / d. The stimulation effect of fracturing is very good.

[0037] The invention improves the perforation effect by modifying the material and structure of the perforating bomb, thereby creating a good cracking channel space. Through the modification of the fracturing gun body, the constraint conditions when breaking holes are reduced, and powerful conditions are provided for the overpressure combustion of the supercombustible particle beam to do work...

Abstract

The invention discloses an overpressure combustion particle beam micro-channel fracture forming device, and particularly relates to a novel high-effect particle beam generating device capable of achieving a micro-channel fracture forming technology of overpressure combustion in the detonation process of perforating bullets for oil and gas wells. The fracture forming device comprises a tubular gunbody, a particle beam buffering device arranged on a through hole of the gun body, a fixing support arranged inside the gun body, a plurality of hole-breaking bullets sequentially arranged and mountedon the fixing support, an overpressure combustion particle beam device arranged at a perforation opening of hole-breaking bullets in a buckled mode and an overpressure combustion particle beam auxiliary device used for restraining the overpressure combustion particle beam device. According to the overpressure combustion particle beam micro-channel fracture forming device, kinetic energy directional loads during energy-gathered perforation are efficiently utilized, pressure field changes formed by explosion of the hole-breaking bullets in a limited space are applied, and the arranged functional devices can orderly utilize the energy gathering effect and the explosion effect of the hole-breaking bullets, so that optimized stress loads are formed among hole seams, the opening degree of wellbores is increased, and the permeability of the near-hole stratum is improved through forming the effective stress loads among holes; and the fracture forming device has a remarkable effect on improvement of oil production and gas production of a single well and transformation and implementation of other measures.

Description

technical field [0001] The invention relates to a perforating and micro-fracturing composite technology, in particular to a super-combustible particle beam micro-channel fracturing device. Background technique [0002] Traditional fracturing composite technology is a state of disordered energy release. The combined effect of the energy-gathering effect and various fracturing agents, although there is a sequence of detonation and ignition, but the work intensity is poor, and the energy is effective or the concentrated work performance is high. discount. How to better combine the degree of perforation opening with the effect of afterload fracturing to achieve better perforation and fracturing effects is the main problem that makes this kind of technology breakthrough technology at present. Contents of the invention [0003] In view of this, the present invention effectively combines the perforation process and particle beam fracturing technology, and can orderly control the...
