Problems solved by technology

Since the first model is rigid, the injection pressure is high and the fluid is difficult to inject during the injection stage, which cannot achieve the purpose of the experiment; the second model can achieve better injection due to the addition of a fluid accumulator , but due to the errors in the measurement and pressure recovery of the accumulator, it is impossible to truly simulate the situation of the reservoir during the production stage

Abstract

The invention relates to an experimental device for simulating multi-component fluid throughput thermal recovery. The experimental device comprises a multi-component injection system (S1), a yield collection system (S2) and a model system (S3). The multi-component injection system comprises a water vapor generating device, a nitrogen generating device and a carbon dioxide generating device. Multi-component fluid generated by the multi-component injection system is injected into a well model of the model system through a middle container. The outlet of the well model is connected with a yield collection device in the yield collection system. According to the experimental device for simulating multi-component fluid throughput thermal recovery, the influences of multi-component fluid injection process parameters on thickened oil thermal recovery can be accurately reflected, and the experimental device is suitable for experimental simulation in the oil-gas field development and exploitation project.

Description

technical field [0001] The invention relates to an experimental device for simulating multi-component fluid huff and puff thermal recovery, which belongs to the experimental simulation device in oil and gas field development and production engineering. Background technique [0002] Heavy oil resources are widely distributed in my country. However, heavy oil has high colloidal asphaltenes, high viscosity, poor fluidity and difficult production. In order to solve the problem of high-efficiency development of heavy oil, oilfield scientific and technological workers have developed a process for efficient production of heavy oil wells using multi-component fluid huff and puff technology. Multi-component fluid is a kind of high-temperature fluid containing water (steam), nitrogen, carbon dioxide and chemical additives, etc., which is used for enhanced recovery in heavy oil fields. Different components in multi-component fluids have different production stimulation mechanisms: hot...
