Sand-packed model pipe full-automatic compacting device

Abstract

The invention discloses a sand-packed model pipe full-automatic compacting device. The sand-packed model pipe full-automatic compacting device comprises a pedestal, a hydraulic cylinder, a hydraulic push rod, a connecting rod, a straight rod and a compacting block. The upper end of the hydraulic cylinder is provided with the hydraulic push rod, the connecting rod is horizontally vertical to the hydraulic push rod, the end of the connecting rod is fixedly connected with an automatic sand-pack tunnel, the interior of the pedestal is provided with an electromagnet, an electromagnet pulse controller, a hydraulic control circuit board, a hydraulic input pipe and a hydraulic output pipe, and the hydraulic input pipe and the hydraulic output pipe are arranged under the hydraulic cylinder and are connected with the hydraulic cylinder. The and-packed model pipe full-automatic compacting device is advantaged in that the pulse controller is used for controlling two poles of the electromagnet to change; when the upward magnetic pole of the electromagnet is opposite to the downward magnetic pole of the compacting block, the compacting block is attracted downwards through a principle that unlike poles attract each other to carry out a compacting process; when the upward magnetic pole of the electromagnet is the same as the downward magnetic pole of the compacting block, the compacting block is pushed up through a principle that two like magnetic poles repel each other; and the sand-packed model pipe full-automatic compacting device replaces manual compacting operation, the labor intensity is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a microbial oil displacement physical simulation experiment device, in particular to a fully automatic compaction device for a sand filling model pipe. Background technique [0002] In the process of oilfield development and reservoir research, the physical parameters of reservoir rocks and fluids are an important basis for compiling oil and gas field development and calculating reserves, studying reservoir properties, performing oil layer comparison, and analyzing oilfield performance. , fluid and the physical parameters of the interaction between fluid and rock. However, the sand filling model experiment is an important means of indoor physical simulation experiments. The process of making the sand filling pipe model is to sieve the quartz sand and mix it according to a certain proportion. Manual filling method layer by layer compaction. Firstly, put the clean core tube and the required mesh of quartz ...

AI Technical Summary

Problems solved by technology

Among them, the existing sand filling work is all done manually, the filling force is small, the force is uneven, and the compaction effect is poor

Based on this, there are also many mechanical automatic compaction devices, but due to the reciprocating compaction of the mechanical mode, the machine requires a large space structure, and it is difficult to accurately control the strength and frequency of compaction
