Abstract

The invention discloses polymer thermal stability detecting equipment and a polymer thermal stability detecting method. The inlet of a first group of constant speed displacement pump is connected to a first displacing fluid storage device; the outlet of the first group of constant speed displacement pump is connected to the inlet of a first intermediate container group; the outlet of the first intermediate container group is connected to the inlet of a homogeneous sand-filled pipe series group; the outlet of the homogeneous sand-filled pipe series group is connected to the inlet of a second intermediate container group; the outlet of the second intermediate container group is connected to the outlet of a second group of constant speed displacement pump; the inlet of the second group of constant speed displacement pump is connected to a second displacing fluid storage device; the homogeneous sand-filled pipe series group is placed in a temperature constant box; a porous medium short section is mounted between the inlet of the homogeneous sand-filled pipe series group and the outlet of the first intermediate container group. According to the polymer thermal stability detecting equipment and the polymer thermal stability detecting method, the influence on the assessment of polymer stability caused by the lack of combination of a plurality of actual conditions in the prior art is effectively solved, and the dynamic stability detection of a polymer solution is realized.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a polymer thermal stability detection device and detection method. Background technique [0002] EOR technologies include polymer flooding, polymer / surfactant binary and polymer / surfactant / alkali triple compound flooding, the main component of which is polymer, which has a high The viscosity is mainly used to improve the mobility ratio of the reservoir displacement agent and crude oil, and to increase the swept volume. The binary or ternary system composite flooding technology has added components to improve the oil displacement efficiency. The polymer solution enters the water injection trunk through the injection pump and is distributed to the injection well, where the polymer solution enters the reservoir through the perforated holes. As the polymer solution entering the reservoir is sheared by rock pores, adsorbed on the rock surface, diluted by reservoir wate...
