Description

multipoint compacting device for sand filling of model

Technical Field

The invention relates to the field of thickened oil thermal recovery experiments in the process of petroleum and natural gas exploration and development, in particular to multipoint compaction devices for model sand filling.

Background

The sand filling model is which is an essential experimental device in a thickened oil thermal recovery experiment, the model is usually cuboid, the whole model is made of stainless steel materials, the inside of the model is filled with sand to simulate a real stratum environment, temperature and pressure measuring points are arranged inside the sand, during the sand filling process of the device, sides of the sand filling are compacted to ensure the compactness of the inside of the model, at present, the manual compaction operation is completely adopted, and an operator compacts the sand filling model by using a compaction wooden hammer or a metal hammer.

The greatest problem of manual compaction is that the compaction force of cannot be guaranteed, which results in different compactness of each layers of the sand-packed model, and further results in different permeability of oil samples in each layers, and finally results in failure of the experiment.

A multi-point compacting device for sand filling of a model comprises a support frame made of aluminum section, wherein the ends of the corners of the support frame are connected through right-angle corner pieces to form a stable supporting structure and provide loading and supporting for other components in the device, a fixed block is fixed at the upper end of the support frame through the corner pieces, the fixed block is formed by cutting the aluminum section, a lead screw is arranged below the fixed block, the lower end of the lead screw sequentially penetrates through the center of a sliding block and the end part of a movable cross beam and is fixed on the fixed block positioned on the side face of the lower end of the support frame, the sliding block is a hollow structure made of stainless steel, threads are arranged inside the sliding block, a driving handle is fixedly connected to the outer side face of the sliding block through a screw, the inner side face of the sliding block is connected with a movable cross beam through a bearing, the movable cross beam is transversely arranged and penetrates through the upper part of a vertically arranged hammer, the lower end of the hammer is made of the stainless steel.

According to the scheme of the invention in step , the screw rod is vertically arranged, is made of stainless steel, is provided with threads on the surface, and the upper end of the screw rod is fixed on the lower surface of the fixed block.

According to the scheme of the step of the invention, the positioning slide block is connected with the support frame through a positioning bolt.

According to the scheme of the invention in step , the sand-packed model is positioned through a positioning slide block.

According to the scheme of the invention in step , rollers are arranged at the lower ends of the support frame and the model support.

Compared with the prior art, the invention has the beneficial effects that:

the device adopts the mechanical device for fixed-point compaction, firstly quantitative sand is filled in the device, after the sand is uniformly stirred, the depth of each compaction of the mechanical device is kept , so that the density of each compacted layer is , the proficiency of an operator is not required, the device is easy to operate by hands, the preparation time of an experiment is shortened, the compactness of the sand inside a sand filling model is ensured, the preparation work of the experiment is also ensured, the problems of low manual compaction efficiency and instability are effectively solved, the device can realize fixed-depth and fixed-distance compaction, and the device is provided with rollers, can move and compact under the condition of , is suitable for sand filling models with various lengths, and has the characteristics of simple structure, good universality and strong universality.
