Solid-fluid coupling pressure controlled hydrocarbon generation and expulsion simulating experimental device

Abstract

The invention provides a solid-fluid coupling voltage controlled hydrocarbon generation and expulsion simulating experimental device. In the device, a high pressure kettle is formed by a high pressure kettle body which is connected with a high pressure kettle top cover and a high pressure kettle base respectively, wherein a vertical pressurizing column is axially arranged in the middle of the high pressure kettle; a three-way valve is connected between the high pressure kettle and a high pressure pipeline in a high pressure buffer which is provided with a piston; the high pressure buffer is connected with a fluid pressure control pump pipeline; a two-way valve with a switch is connected to a connecting pipeline of the three-way valve and a gas collecting device; a stainless steel piston is arranged in the high pressure buffer, and distilled water for controlling pressure and stratum simulated fluid are filled in cavities at two sides of the stainless steel piston; an upper connecting hole and a lower connecting hole on the high pressure reacting kettle are communicated through the high pressure pipeline; and the high pressure pipeline is communicated with the three-way valve.

AI Technical Summary

Benefits of technology

This patented technology allows for accurate simulations of under ground hydraulic systems that involve pressurized fluids or gases generated from oil wells. It uses special tools called pipes made up of two parts - one part connects an upper connection pipe through another connector at its top end and another section goes into the bottom where there'll also have other connections like a triple joint valves. A tapered metal plate may move along this channel to help equalizing the flowing liquid and keep it stable during testing. Additionally, some experiments use different types of liquids such as water (H2O) and gasoline (C1-4). Overall, these technical means aim to provide reliable data about underground environments when studying various processes related to production and exploitation scenarios.

Problems solved by technology

This patented technical problem addressed in this patents relates to studying how well fluids flow through reservoirs during oil production from an underground formation without causing damage or affecting other formations nearby. Current hydraulics models for analyzing sedimentary basin water involve simplifying assumptions about the underlying processes such as temperature, stress-strains, fluid compositions, etc., but they may fail due to insufficiently controlled pressures caused by impervious materials near the bottom of the borehole.
