    IN SITU WATER-ROCK INTERACTION APPARATUS FOR USE
    WITH DOUBLE PACKER Cross Reference to Related Demand
    The present application claims the priority and benefit of the Korean patent application 10-2013-0127552, filed October 25, 2013, the disclosure of which is incorporated herein by reference, in its entirety.
    Context
    Field of the invention
    The present invention relates to an interaction apparatus which analyzes physical, chemical and microbiological occurrences and their effects according to an interaction between water and rock at a predefined zone in a deep borehole, in which there is a single fracture, a fracture network and a fracture zone, and more particularly an in situ rock - water interaction apparatus that can be installed in a double packer system. In addition, the present invention relates to an in situ rock-water interaction apparatus for use with a dual packer, which can be installed in the dual packer system to analyze reaction phenomena, such as water intrusion. sea, groundwater contamination, tracer testing and clogging of a fractured rock mass, and their reasons, as well as an interaction between water and rock (a drill core sample in the same section ) in a predefined area closed between the double packers in a well.
    Discussion of the related art
    It is generally difficult to conduct a reaction test (physical, chemical and microbiological occurrences and their effects) between water and rock at a main hydraulic fracture existing in a predefined zone in a deep borehole, on the site. This is because there is no reaction apparatus for conducting an in situ test. Since most interactions between water and rock are performed only with a column test in a laboratory, it is difficult to guarantee the accuracy and reliability of the analyzed results of the in situ test.
    In addition, an existing reaction apparatus is an apparatus for observing an interaction between water and rock in an open well (wells completely penetrated). A water-rock interaction device installed in a predefined area rarely has water quality, as there is groundwater flow from a predefined area due to water quality mixed open well.
    In order to solve the many environmental problems in the well, an "in situ rock-water interaction apparatus" (hereinafter referred to as "base technology") is described in Korean patent application 10-2013-0002042.
    The basic technology includes a ring-shaped upper rack, a plurality of posts that are attached to the upper rack, a lower rack which is attached to the lower ends of the posts, a bottom plate that is arranged at the bottom lower rack level to form a bottom, and a mounting part that is installed at the upper rack and performs the in situ test that observes and analyzes the interaction between the rock and the water generated at a predefined area of the cased well, and thus stably and accurately analyzes the reaction phenomenon between the water and the drill core samples.
    However, in the basic technology, as illustrated in FIG. 6, the water-rock interaction apparatus is controlled to be positioned in a predefined area in the open well by means of a cable (or a wire) connected to an upper annular shape of the water - rock interaction apparatus. In addition, the water - rock reaction phenomenon may not be considered as the water - rock reaction phenomenon in a predefined zone due to the quality of the mixed water of an open well. Therefore, the development of a new technology is needed to compensate for and remedy the lack of basic technology. Summary of the invention
    According to one aspect of the present invention, there is provided an in situ rock-water interaction apparatus for use with a dual packer comprising: a plurality of posts; an upper fastener connected to the upper ends of the uprights; a lower fastener connected to the lower ends of the uprights; upper and lower packers connected with the upper and lower fasteners; coupling means comprising a socket and a nipple provided at the upper and lower fastening elements for connecting the upper and lower fasteners with the upper and lower packers.
