Multi-point compaction device used in model sand filling process in heavy oil thermal recovery experiment

Abstract

The invention belongs to the technical field of petroleum and natural gas exploitation simulation, and discloses a multi-point compaction device for the sand filling process of a model in a thickenedoil thermal recovery experiment. A sand filling model is installed on a model bracket, and the sand filling model is supported and positioned through the model bracket; positioning sliding blocks arearranged on the two sides of the sand filling model, and the positioning sliding blocks are connected with supporting frames through positioning bolts to fix and position the sand filling model; the upper ends of the supporting frames are connected with fixed blocks through screws; all the corner ends of the supporting frames are connected through right-angle corner parts; the fixed blocks are located on the upper parts of guiding rods, and the guiding rods successively penetrate through the fixed blocks, sliding blocks and a moving cross beam from top to bottom; the sliding blocks and pneumatic handles with the adjustable pressure are connected and fixed through screws; and the moving cross beam penetrates through a driving hammer, and the driving hammer is located above the sand fillingmodel. According to the multi-point compaction device for the sand filling process of the model in the thickened oil thermal recovery experiment, various defects of existing manual compaction operation are overcome, it can be ensured that the compaction force is the same each time, the safety of a line can also be ensured, and fast, stable and safe compaction operation is realized.

Description

technical field [0001] The invention belongs to the technical field of petroleum and natural gas exploitation simulation, and in particular relates to a multi-point compaction device used in a model sand filling process in a heavy oil thermal recovery experiment. Background technique [0002] At present, the closest existing technology: the existing sand-fill compaction for large-scale 3D physical models often uses manual compaction to carry out sand-fill compaction on physical models, which is inefficient and inconsistent in compaction conditions, resulting in During the experiment, the oil and water flowed along the side wall of the model, which led to the failure of the experiment. Compaction is the process of integrating loose sandy soil into a denser whole. Manual compaction is to use some compaction tools (hammer, flat plate) to exert pressure on sandy soil manually. Different people use different forces in the compaction operation, and even the same person cannot ac...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problems existing in the prior art are: the prior art uses manual single-point compaction for compaction, which is not only inefficient, but also cannot guarantee the consistency of compaction each time. It will also cause damage to the circuit, which will affect the accuracy of subsequent experiments.
