High-temperature high-pressure fluid solid-phase deposition simulation device

Abstract

The invention provides a high-temperature high-pressure fluid solid-phase deposition simulation device, which comprises a sample injection system for configuring and outputting a fluid sample; a solidphase deposition system communicated with the sample injection system and used for carrying out solid phase deposition on the fluid sample output by the sample injection system; and a back pressure system communicated with the sample injection system and the solid phase deposition system and used for controlling the pressure of the solid phase deposition system. The sample injection system is used for preparing the fluid sample and inputting the fluid sample into the solid phase deposition system, solid phase deposition is carried out on the fluid sample, the pressure of the solid phase deposition system is controlled through the back pressure system, and magnitude detection is carried out on the solid phase deposit by adopting a weighing method. The device has the beneficial effects thatthe problem of solid phase deposition in deep gas reservoir, condensate gas reservoir and gas injection miscible flooding oil reservoir exploitation is solved, a scientific research means and a prediction evaluation technology are provided, reservoir damage blockage and wellbore are avoided, and oil reservoir exploitation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of solid-phase deposition, and in particular relates to a high-temperature and high-pressure fluid solid-phase deposition simulation device. Background technique [0002] The problem of organic solid phase deposition in oil and gas hydrocarbon systems is a very necessary research topic in the oil and gas industry. In the process of oil and gas field production, the problems of formation fluid channels and wellbore solid phase deposition and organic solid phase deposition have long troubled people. , and pressure changes will cause asphaltene precipitation in crude oil, resulting in reservoir damage and blockage and wellbore blockage. At present, there is no relevant equipment that can predict and solve the problem of solid phase deposition, which makes solid phase deposition prone to occur during oil reservoir development, making mining difficult. . Contents of the invention [0003] In view of the above...
