High-temperature and high-pressure clamp holder and using method thereof

Abstract

The invention provides a high-temperature and high-pressure clamp holder and a use method thereof, relates to the technical field of clamping parts of testing devices, and can synchronously improve temperature and pressure indexes of the clamp holder. The holder comprises a first adjusting plug, a second adjusting plug, a barrel, an electric heating sleeve, a rubber sleeve, a cushion block and a support, the rubber sleeve is sleeved in the middle of the barrel, the first adjusting plug and the second adjusting plug are mounted at two ends of the barrel respectively, conical plungers of the adjusting plugs are inserted into the rubber sleeve, a rock core containing space is arranged in the middle of the rubber sleeve, and the cushion block is arranged in the rock core containing space. Cushion blocks are arranged at the two ends of the rock core containing space respectively; the bracket is connected with the cylinder body; a seepage through hole is formed in the adjusting plug along the axis, and a plurality of stress application holes are formed in the adjusting plug in the radial direction; the cylinder body is provided with an annular pressure loading channel which is communicated with the outer side of the rubber cylinder; and the side wall of the cylinder body is also provided with a temperature measuring hole. The structure eliminates the shearing force under the high-pressure condition, so that the pressure resistance of the rubber sleeve is improved, and the rubber sleeve is also suitable for tests in which flammable and explosive gas participates.

Description

technical field

[0001] The invention relates to the technical field of clamping components of testing devices, in particular to a high-temperature and high-pressure clamp and a method for using the clamp. Background technique

[0002] The holder is a device used to simulate formation conditions, put the core into the holder, use this device to effectively simulate the temperature and pressure of the bottom layer, and transmit the temperature and pressure to the core to simulate the temperature of the formation where the core is located and stress conditions. Using the entrances and exits set up upstream and downstream of the device, various displacement seepage tests can also be carried out on the core. At present, the temperature and pressure synchronization index generally achieved by the holder is 120°C-40MPa, which can meet the conventional simulation experiments. However, for some high-pressure and low-permeability cores, the formation environment cannot be effectively...
