Description

Technical Field

[0001] The invention relates to the technical field of shale hydrocarbon generation and expulsion, and in particular to a shale hydrocarbon generation and expulsion simulation device with a liquid and gas pipeline anti-blocking function. Background Art

[0002] Shale oil and gas is an unconventional oil and gas resource stored in the nanopores of shale, and has become the main growth point of the world's oil and gas resources. Unlike oil and gas resources in conventional reservoirs, oil and gas in shale are self-generated and self-stored, and their hydrocarbon generation and expulsion patterns not only significantly control the amount of oil and gas resources in shale, but also affect the exploration and development of shale oil and gas. However, different types of shales have different hydrocarbon generation and expulsion patterns under geological conditions, and the hydrocarbon generation and expulsion patterns of the same shale in different geological environments are also significantly different. How to identify the hydrocarbon generation and expulsion pattern of shale under limited geological conditions is one of the key issues facing shale oil and gas exploration and development.

[0003] Under geological conditions, the system in which shale is located during the hydrocarbon generation and expulsion process will change with the evolution of the burial history of the formation. During the deep burial of the formation, due to the compaction of the overlying formation, the shale is in a closed system as a whole, and the oil and gas generated by the shale are difficult to be discharged from the shale layer; and during the uplift of the formation, due to the release of the pressure on the shale layer, the shale is in a semi-open system as a whole, causing some oil and gas in the shale to migrate out of the shale layer. In the complex geological evolution process, the hydrocarbon generation and expulsion process of shale may be affected by multiple periods of deep burial and uplift. Since the current shale oil and gas reservoirs have undergone the cumulative effects of multiple periods of tectonic activities, it is difficult to reveal the hydrocarbon generation and expulsion pattern of shale under a specific geological environment based on the analysis of geological samples.

[0004] The simulation experiment of hydrocarbon generation and expulsion of typical shale samples is one of the most effective methods to reveal the hydrocarbon generation and expulsion mode of shale. The experimental devices commonly used in scientific research either use a closed system, such as a closed system based on gold tubes, quartz tubes and glass tubes, or a semi-open system, such as a hydrocarbon generation and expulsion press device. At present, there is a lack of an experimental device that can effectively switch and control the closed / semi-open system. In addition, the hydrocarbon generation and expulsion of shale causes the shale sample to break, accompanied by a large amount of fine shale dust; at the same time, the shale in the shale reactor has been in a high temperature environment (experimental temperature>300℃), and the generated shale oil and gas will produce a very high pressure in the reactor. During the continuous generation and discharge of shale oil and gas, it is very easy to carry shale dust in the reactor, causing blockage of the transport system and affecting the effective discharge of shale oil and gas. How to prevent the blockage of the transport system has always been a technical bottleneck faced by the shale hydrocarbon generation and expulsion simulation device. The commonly used measure is to place a layer of filter at the interface of the transmission pipe, but the application effect of the method is poor, especially when a large amount of oil and gas is discharged. Once the filter is clogged, it is difficult to replace the filter during the experiment, and a new experiment needs to be carried out. Since the simulation experiment cycle of shale hydrocarbon generation and expulsion is long (usually 7-30 days), the blockage of the device will lead to low overall efficiency of the device and consume a lot of manpower and material resources. Therefore, it is necessary to develop a shale hydrocarbon generation and expulsion simulation device with liquid and gas pipeline anti-blocking function. Summary of the invention
