Embodiment 1
[0036] Such as Figure 1 to Figure 3 As shown, this embodiment provides a device for deflagration fracturing simulation experiments of horizontal wells. The device mainly includes three parts: a rock sample holding device, an impact loading device, and a control analysis device; the rock sample holding device is used for placement For cores with different characteristics, the impact loading device is used to provide external force loading to the rock sample clamping device to make the core under different levels of impact simulation environments, and the control analysis device is used to analyze various data of the core under different simulation environments.
[0037] Among them, the rock sample clamping device includes a cylindrical cylinder (1-15), the cylinder is horizontally arranged, and the bottom of the cylinder bottom is provided with two support seats (1-11) for supporting the cylinder, and the two cylinders The end is provided with a left core plug and a right core pl...
Embodiment 2
[0043] A device for horizontal well deflagration fracturing simulation experiment. The structure is as described in Example 1. The difference is that the rubber sleeve (1-17) also passes through four equally spaced internal support seats (1- 16) Fixed in the inner cavity of the cylinder (1-15). The inner support seat is mainly used for reinforcement, providing greater support for the rubber sleeve, and avoiding the overweight experimental core from crushing the rubber sleeve.
Embodiment 3
[0045] An operating method for deflagration and fracturing simulation experiments of horizontal wells, using the device described in Example 2. The specific operating process is as follows:
[0046] (1) According to the experimental requirements, make rock samples with different lithology, dry the prepared rock samples and use a core drilling machine to drill the cores, and then polish the cores. After the polishing treatments, the prepared cores Saturation treatment.
[0047] (2) Put the rubber sleeve (1-17) on the left core plug (1-12) where the thread is not engraved, install the wire mesh sleeve (1-18) in the rubber sleeve, and put this whole In the inner cavity of the cylinder, when the left core plug is in contact with the inner support seat (1-16), put the experimental core into the wire mesh sleeve (1-18) and put it on the other end of the rubber sleeve (1-17) Put the upper right core plug (1-2), and then install the tightening steel rings (1-6) at both ends, and then inst...
