Automatic sand pack tube model compaction device for physical simulation

Abstract

The invention relates to an automatic sand pack tube model compaction device for physical simulation, mainly solving the problem of poor compaction effect caused by small manual sand pack stress and uneven stress in the existing manufacturing process of the sand pack tube model. The device is characterized in that a slider in sliding fit with a slide guide bar is arranged at the external of the slide guide bar, the external of the slider is provided with a boss B, a transmission screw rod is engaged with a gear arranged at the external of the transmission screw rod, and the external of the gear is provided with a boss A. The slider and the gear both pass through a horizontal support beam and are respectively connected with the support beam through the boss B and the boss A. The middle of the support beam is fixedly connected with a hydraulic cylinder vertical to the support beam, and the hydraulic cylinder and a hydraulic pushrod arranged below the hydraulic cylinder are vertically aligned with the sand pack tube. By using the compaction device, manual compaction is replaced by machinery compaction of a hydraulic cylinder plunger, therefore, the compaction device has the characteristics of reduced labor intensity of the workers, even stress on the sand pack tube, and good compaction effect.

Description

technical field [0001] The invention relates to an experimental device for improving oil recovery, in particular to an automatic compacting device for a sand filling pipe model used for physical simulation. Background technique [0002] The physical parameters of reservoir rocks and fluids are important basic data for oilfield development and reservoir engineering research, and are an important basis for compiling oil and gas field development plans, calculating reserves, studying reservoir properties, comparing oil layers, and analyzing oilfield dynamics. Oilfield development experiments are the main means to obtain the physical parameters of these rocks, fluids and the interaction between fluids and rocks. [0003] In the process of oilfield development, rock cores are often used to carry out various physical modeling experiments. The sand-filling pipe model experiment is an important means of indoor physical simulation experiments. The process of making the sand-filling...
