A thermal pressure simulation system and method based on a capsule reactor

Abstract

The invention provides a hot pressing simulation system based on bladder type reaction kettles. The system comprises a bladder type reaction kettle unit, an automatic collecting and metering unit, a fluid pressure supply unit and a control and processing unit, wherein the bladder type reaction kettle unit comprises at least one bladder type reaction kettle. The bladder type reaction kettles, independent heating pipes, a temperature control device and an automatic collecting and metering device are used as a simulation set, and the controller is used for independently controlling the temperature of the bladder type reaction kettles, so that hydrocarbon generation and discharging processes of one sample at different temperatures are simulated at the same time or hydrocarbon generation and discharging processes of different samples at the same temperature are simulated, and possibility is provided for completely simulating the hydrocarbon generation capability of hydrocarbon source rock.Each bladder type reaction kettle adopts a bladder type reaction vessel arranged in a reaction kettle body as a sample chamber, and each reaction vessel adopts a bladder type thin-wall pressure-resistant cavity made of nickel-based alloy steel for replacing an existing gold tube as a reaction vessel chamber. The hot pressing simulation system has the advantages of low cost, large volume and high applicability.

AI Technical Summary

Problems solved by technology

However, the gold tube simulation experiment method mainly has the following defects: the volume of the gold tube reaction vessel is small, and the filling amount of the experimental sample is small, so it is only suitable for source rocks, oil shale, coal, etc. with an organic carbon content greater than or equal to 2%. The applicability of organic deposits is limited; the gold tube is a closed reaction vessel, and the gas components of liquid hydrocarbons and heavy hydrocarbons cannot be discharged in time, and secondary cracking is prone to occur under high temperature conditions; the material price of the gold tube is high, which leads to the cost of the experiment high
