Abstract
The invention relates to the technical field of detection of a seepage field of a rock core and discloses an experiment device and method for determining a horizontal seam seepage field of a low-permeability rock core. The experiment device for determining the horizontal seam seepage field of the low-permeability rock core comprises a clamping device and an artificial rock core, wherein the artificial rock core is provided with at least one horizontal seam and is connected with a plurality of testing points. The experiment device for determining the horizontal seam seepage field of the low-permeability rock core, provided by the invention, can realize pressure distribution and flow testing in a seepage process, so that a seepage mechanism of the horizontal seam of the low-permeability rock core is determined.
Description
technical field [0001] The invention relates to the technical field of measuring seepage fields of rock cores, in particular to an experimental device and method for measuring seepage fields of horizontal fractures of low-permeability rock cores. Background technique [0002] The development of low-permeability reservoirs by vertical wells often requires fracturing, and the fractures formed by fracturing are mainly vertical fractures parallel to the wellbore. Scholars at home and abroad have done a lot of research on the seepage of vertical fractures. However, in recent years, during the development of some shallow low-permeability reservoirs in my country, the problem of horizontal fractures has been encountered when the buried depth of the reservoir is shallow or the fracture pressure gradient of the reservoir is small. There is still little research on the seepage of horizontal fractures at home and abroad. According to literature and patent searches, the current research...
