Horizontal-well physical simulation experiment device and experimental method thereof

Abstract

The invention relates to a horizontal-well physical simulation experiment device and an experimental method thereof. The horizontal-well physical simulation experiment device is composed of an injection system, a horizontal-well physical simulation device, a mining system and a data analysis and collection system. By adoption of an actual core, different ways of development of a horizontal well can be subjected to dynamic simulation, mining processes such as depletion-driven development, gas-injection huff and puff and displacement, and segmented perforating mining of the horizontal well can be simulated under the condition of high temperature and high pressure of an actual stratum; the actual core can be used in the study of affect of the different ways of the development of the horizontal well upon improvement of a mining rate, and provide of basis for numerical reservoir simulation and field development adjustment of the horizontal well.

Description

technical field [0001] The invention relates to a horizontal well physical simulation experimental device and an experimental method thereof, belonging to the technical field of petroleum development experiments, in particular to an experimental device and an experimental method for simulating horizontal well development in indoor experiments. Background technique [0002] At present, in the field of petroleum development experiment technology, the research on the physical simulation of horizontal well production is mainly to use the three-dimensional physical simulation sand filling model to simulate the production experiment of horizontal wells in different types of oil and gas reservoirs. This traditional experimental model device uses a homogeneous sand-packed pipe, which cannot reflect the heterogeneity of the real formation and the physical properties and flow state of the formation fluid. The patent with the application number 201210182456.5 discloses a downhole physi...
