Embodiment 1

[0017] Embodiment 1: refer to accompanying drawing 1. The high-temperature and high-pressure glass microscopic model holder is mainly made of a model bed base 7, made of stainless steel, with an external diameter of 120 millimeters and a height of 45 millimeters, with external threads on the upper end. Model bed body loam cake 14, stainless steel material is made, and external diameter 90 millimeters, height 55 millimeters, internal thread is arranged at the lower end. Model bed body base 7 is threadedly connected with model bed body loam cake 14. An O-shaped sealing ring 8 is arranged between the model bed body base 7 and the model bed body upper cover 14 . Model bed body base 7 and model bed body loam cake 14 centers have the through hole with step, respectively have a glass window 2 in the through hole. The glass window 2 is made of transparent glass with a thickness of 15 mm and a diameter of 24 mm. Gasket 9 is arranged on the center through hole step of model bed body ...

Abstract

The clamper is used for high temperature and high pressure glass miniature modules that is meant to judge the water drive oil effects and review in oil and gas exploration. On the base of the module and the center of the module cap, there are holes with steps and glass viewing window inside. Among the glass viewing window, module base and the inner wall of the central hole of the module's top cap, there is an O type sealing gasket. Between the module base and the top cap of the module, a high pressure confined chamber is formed. A high pressure pipe is fixed on the duct that is the head of the top cap of the module. Inside the high pressure confined chamber, there is a module bracket. A miniature transparent simulation porous module is pressed tightly against the module bracket. The invention can finish the simulative study of miniature transparent simulative porous module under the high temperature and high pressure of the strata, observing the module porosity and the liquid within the clamper clearly under the microscope. The experiment data surpass the current result in constant temperature and pressure.

Description

technical field [0001] The present invention relates to the technical field of oil field development evaluation research, in particular to an instrument for water flooding effect and evaluation in the process of oil field development, which is an experimental research instrument for mutual displacement of multiphase fluids in visible pores. Model holder. It is applied to the experimental study of the mechanism of seepage and migration of indoor fluid. Background technique [0002] In the research process of oil and gas field development, especially in the research process of oil field development secondary oil recovery and tertiary oil recovery, and oil layer protection, it is necessary to evaluate the effect of water flooding and the effects of various chemical agents used. The evaluation is based primarily on experimental studies of mutual displacement of multiphase fluids in visible formation pores. The experimental model mainly adopts the microscopic simulation transpa...
