Embodiment Construction

[0031] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0032] Such as Figure 1-3As shown, the downhole long-period fluid flux monitoring device includes a first device 31 , a second device 32 , a first packer 33 , a second packer 34 , and a casing 35 . The lower end of the first device 31 is connected to the first packer 33, the second device 32 is connected to the second packer 34, and the lower end of the first packer 33 is fixedly connected to the upper end of the second packer 34 through several casing pipes 35, so that The first device 31 and the second device 32 constitute an integral device. Both the first device 31 and the second device 32 are set in the external monitoring pipe string 36 , the lower end of the monitoring pipe string 36 is inserted into the well, and the fluid enters the monitoring pipe string 36 from the lower end of the monitoring pipe string 36 . Both the first packer 33 and t...

Abstract

The invention discloses an underground long-period fluid flux monitoring device and method. The underground long-period fluid flux monitoring device comprises a first device and a first packer, the first packer adopts a first micro-diameter hose and a second micro-diameter hose to absorb fluid and a tracer agent in a main flow pipeline and displays the fluid and the tracer agent in a layered mode so as to calculate the long-period fluid flux. The first packer is used for expanding and packing a target area, so that fluid below the first packer completely enters the main flow pipeline through a hole of the first packer, and the accuracy of a final calculation result is improved. In addition, a second device and a second packer are added to be connected with the first device and the first packer in series for use, and calculated fluid flux results can be compared.

Description

technical field [0001] The invention relates to the technical field of downhole fluid monitoring and collection, in particular to a downhole long-period fluid flux monitoring device and method. Background technique [0002] International Ocean Drilling is an international scientific cooperation program with the largest scale, the longest duration and the most far-reaching influence in the field of earth and ocean science in the world. It is also an important scientific and technological platform leading contemporary international deep-sea exploration. For nearly half a century, the scientific results obtained by ocean drilling have confirmed the theories of seafloor spreading, continental drift and plate tectonics, and greatly promoted the development of earth science. [0003] Ocean drilling scientific research is to obtain sediments and deep rocks by drilling, which is of great significance for the study of geodynamics, paleoceanography, biosphere, deep microorganisms, col...
