Multifunctional oil reservoir simulation experiment device and experiment method thereof

Abstract

The invention discloses a multifunctional oil reservoir simulation experiment device. The device comprises a cubic vessel, a simulation experiment pit-shaft (1), a multi-parameter sensor (2), and cable connectors (3). The cubic vessel comprises a box body (4) and a cover plate (5), wherein a cavity is formed inside the box body (4), a plurality of inserting holes (6) are distributed in a base plate of the box body (4), partition plates (7) are evenly arranged all around each inserting holes (6), connecting holes are formed in the side wall of the box body (4), the pit-shaft (1) of a simulation pit and the wire cable connectors (3) are installed inside different inserting holes, and the multi-parameter sensor (2) is placed inside the cavity. The invention further discloses an experiment method using the device. The device and the system have the advantages of being capable of simulating various pit conditions, even in distribution of pressure in the bottom portion of the box body, also capable of simulating sites where stimulation pressure is distributed unevenly, capable of measuring flow in any small sections inside any pit-shaft, genuine and believable in experiment result, and capable of intuitively observing bottom water rising trends.

Description

technical field [0001] The invention relates to the technical field of petroleum development, in particular to a multifunctional oil reservoir simulation experiment device and an experiment method thereof. Background technique [0002] In recent years, a large number of bottom water reservoirs have been discovered in the field of oil and gas field development. For the development of bottom water reservoirs with sufficient bottom water energy, after the oil field is put into production, with the recovery of crude oil, the formation pressure gradually decreases, and the bottom water energy is greater than the oil layer energy. At the same time, due to the difference in oil-water viscosity, the bottom water gradually enters In the oil layer, once the bottom water breaks through and rises to the wellbore during the production process, the water content of the oil well will rise rapidly, resulting in a rapid decline in crude oil production, which seriously affects the normal prod...
