Artificial core small batch production device

Abstract

The invention provides an artificial rock core small batch production device, comprising a core cabin, a core cabin holder (7), a top pressing plate (8), a bottom cushion plate (9) and a pressing head(6). The device is characterized in that: the core cabin is composed of a top plate (1), a bottom plate (4) and a sleeve (2); the core cabin is arranged in the core cabin holder (7), which is provided with a plurality of holes for arranging the core cabin, a bottom base plate (9) is arranged on the lower portion of the core cabin holder (7), the top plate (1) is provided with the pressure head (6), and the pressure head (6) is connected with a top pressing plate (8). According to the artificial core small batch production device, structure is simple, and production is easy, practicability andefficiency is high, sizes and pore infiltration performance of the core samples prepared in the batch can be guaranteed to be the same, experimental errors caused by differences between samples in anindoor evaluation experiment can be eliminated, a powerful technical support is provided for drilling and mining technologies and technological research in unconventional oil and gas resource exploration.

Description

technical field [0001] The invention relates to a small-batch manufacturing device for artificial rock cores. Background technique [0002] At present, domestic unconventional oil and gas resources are being explored and developed in full swing, especially shale gas and coalbed methane resources have been built into large-scale commercial mining areas. However, there are still large areas of shale gas and coalbed methane blocks that are still in the exploration stage, and the unconventional oil and gas wells in the commercially exploited areas have improved in wellbore stability, cementing quality improvement, reservoir protection and post recovery. In terms of improvement, it is still necessary to further improve the drilling technology and process, and the indoor experimental evaluation is very important to solve the above problems. [0003] Because shale has strong water sensitivity, high density, and low permeability, and most coal rocks have low mechanical strength and...

AI Technical Summary

Problems solved by technology

However, there are still large areas of shale gas and coalbed methane blocks that are still in the exploration stage, and the unconventional oil and gas wells in the commercially exploited areas have the advantages of wellbore stability, cementing quality improvement, reservoir protection and late recovery. In terms of improvement, it is still necessary to further improve the drilling technology and process, and the indoor experimental evaluation is very important to solve the above problems

[0003] Because shale has strong water sensitivity, high density, and low permeability, and most coal rocks have low mechanical strength and well-developed cleats, a large number of core columns are needed for relevant experimental research and effect evaluation before exploration and development. However, the actual formation The number of cores is small and precious, and the existing equipment can only make artificial cores individually, resulting in the inability to effectively carry out sufficient indoor experimental evaluation work, creating difficulties for the exploration and development of unconventional oil and gas resources.
