Description
Technical Field
The invention relates to the technical field of oil exploitation tests, in particular to a simple sand filling pipe compacting device.
Background
With the development of economic technology in China, the demand of petroleum resources is increasing day by day, and the difficulty of petroleum exploration and development is increasing along with the development. Several main oil fields in China also enter a high water content stage, and the development difficulty is gradually increased.
In order to further improve the oil recovery efficiency of the oil field, a scientific and reasonable development scheme must be established. The physical parameters of reservoir rocks and fluids are important bases for oil field development and reservoir engineering research. And meanwhile, the method is also an important basis for compiling an oil field development scheme and calculating the crude oil reserves.
In order to research the physical parameters of the fluid under different conditions in the rock, a physical model experiment is a common technical means. The rock core used for developing the physical model experiment is generally a real stratum rock core, an artificial rock core and a sand filling pipe model. The real core is usually obtained by coring in the oil field drilling process, the obtaining difficulty is high, and the real core is not easy to obtain, so that the real stratum core is rarely used for carrying out experiments in a common laboratory. The artificial rock core is formed by cementing different sand grains and is a simulated rock core produced by simulating the formation conditions. The rock core is easy to obtain, but problems occur during use, and the cementation degree is not easy to control, so that the difference of the artificial rock core is very large, and the actual condition of the underground real rock core cannot be well simulated. The sand-packed tube mode is obtained by packing quartz sand. The sand-packed pipe model can control different permeability through different sand-packed particle sizes, and can be recycled. Therefore, the method is a common physical model experiment mode for laboratories.
An important influence factor of the sand filling pipe model in sand filling is the compactness of quartz sand. If the quartz sand in the sand filling pipe is compressed by manual operation and is difficult to compact, the sand filling pipe model with large porosity, large permeability and low permeability cannot be obtained. The sand pack must therefore be pressurised mechanically to achieve a lower permeability. The existing sand-filled pipe pressurizing device is, for example, an invention patent (an automatic sand-filled pipe model compacting device for physical simulation) with an application publication number of CN102022114A of 2011, 4, month and 20; a utility model patent with publication number CN203908845U (used for core compaction equipment in laboratories) granted on 10/29/2014; utility model patent No. CN204386595U (a mechanical long tube sand-packed model compacting device) granted No. 10/6/2015; an invention patent (an automatic compaction device for sand-packed model tubes) with an authorization publication number of CN105437589A (3 months and 30 days in 2016); an invention patent (a full-automatic compaction device for sand filling mold type pipes) with the application publication number of CN105464653A (4/6/2016); the sand-filling pipe compacting devices are large in size and inconvenient to operate.
