Description

Technical Field

[0001] The invention relates to the technical field of turbine fracturing, and in particular to an air source system for supplying air to a turbine engine by using a fracturing manifold device. Background Art

[0002] Hydraulic fracturing has been used for decades to increase the production of oil or gas wells. This method uses a fracturing pump to pump fluid into the wellbore under high pressure, and then squeezes the fluid into the formation to open cracks. Water, other liquids and fracturing proppants are also injected into the cracks. After fracturing is completed, the fracturing fluid is returned to the ground, and the fracturing proppants remain in the cracks to prevent the cracks from closing. A large amount of oil and gas enters the wellbore through the cracks and is produced.

[0003] At oil and gas field fracturing sites around the world, the gas source supply for turbine fracturing is as follows:

[0004] The turbo fracturing trucks are placed in parallel, the gas source pipelines are connected between the turbo fracturing trucks, the gas source filters are placed at the accessory position of the turbo fracturing truck, and the entire gas source pipeline is arranged around the vehicle group.

[0005] The problems are as follows:

[0006] 1. Unsafe: The gas source filter is placed at the rear of the turbine fracturing truck, which is a high-pressure area. There is a risk of the filter being damaged, and most gas source filters are not protected safely. Once the high-pressure pipeline leaks, the gas supply will eventually be disconnected, affecting the work efficiency of the well site.

[0007] 2. Unreasonable layout: The gas source pipeline of the entire vehicle group is in a ring form. If one of the turbine fracturing vehicles needs to be driven away, the pipeline of the entire vehicle group will be broken, and there is a risk of gas shortage, which affects the work efficiency of the well site.

[0008] 3. The structure is not compact enough, and the installation is time-consuming and labor-intensive: After the well site is arranged, it is necessary to temporarily install gas source filters, gas source pipelines and other materials, which increases the difficulty of well site installation and affects construction efficiency. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an air source system that uses a fracturing manifold device to supply air to a turbine engine. By integrating the air source delivery manifold and the filtering device on the manifold device at the fracturing site, the on-site wiring of the air source delivery manifold in the prior art is avoided, the installation time is saved, the difficulty of well site installation is reduced, and the installation efficiency is improved; the change in the position of the filtering device also eliminates the dangerous hidden dangers of the high-pressure area at the rear of the turbine fracturing vehicle in the prior art; the connecting device makes the air supply more flexible, from the series air supply between the turbine fracturing vehicle groups in the prior art to the parallel air supply, the running or non-running of a single turbine fracturing vehicle does not affect the air supply of other turbine fracturing vehicles, and it only needs to turn off the valve and disconnect the quick interface; the provision of the protective device separates the fracturing manifold and the air source delivery manifold, thereby increasing safety.

[0010] The objective of the present invention is achieved through the following technical measures: a gas source system that utilizes a fracturing manifold device to supply gas to a turbine engine, comprising a gas supply device, a gas source delivery manifold, a filtering device, a gas detection system and a connecting device, wherein the gas source delivery manifold, the filtering device and the gas detection system are integrated on the fracturing manifold device, the gas supply device is connected to the gas source delivery manifold through the filtering device, and the gas source delivery manifold supplies gas to the turbine engine through the connecting device.

[0011] Furthermore, the gas source system that uses the fracturing manifold equipment to supply gas to the turbine engine includes a protective device, which is integrated on the fracturing manifold equipment and is used to isolate the gas source transmission manifold from the fracturing manifold on the fracturing manifold equipment.

[0022] like Figure 1 As shown, a gas source system for supplying gas to a turbine engine by using a fracturing manifold device includes a gas supply device 1, a gas source delivery manifold 2, a filter device 3, a gas detection system 4 and a connecting device 6. The gas source delivery manifold 2, the filter device 3 and the gas detection system 4 are integrated on the fracturing manifold device 7. The gas supply device 1 is connected to the gas source delivery manifold 2 through the filter device 3, and the gas source delivery manifold 2 supplies gas to the turbine engine through the connecting device 6. At the actual fracturing operation site, the fracturing manifold device 7 is arranged near the wellhead, and its function is to transport the fracturing fluid in the fracturing device to the wellhead. The engine of the fracturing device is a plunger pump through power, and the plunger pump pumps the fracturing fluid into the wellhead. The fracturing device is also arranged around the fracturing manifold device 7 at the actual site. The engine of the fracturing device in this technology is a turbine engine. This technical solution integrates the gas source transmission manifold 2 and the filter device 3 on the manifold equipment at the fracturing site, thereby avoiding the on-site wiring of the gas source transmission manifold 2 in the prior art, saving installation time, reducing the difficulty of well site installation, improving installation efficiency, and reducing the space occupied by the gas source transmission manifold 2 and the filter device 3 in the prior art. The position of the filter device 3 is changed from the high-pressure area at the rear of the turbine fracturing vehicle in the prior art to being fixed on the fracturing manifold equipment 7, and the hidden dangers of the filter device 3 are also eliminated.

[0023] The gas source system for supplying gas to the turbine engine by using the fracturing manifold equipment includes a protective device 5, which is integrated on the fracturing manifold equipment 7 and is used to isolate the gas source delivery manifold 2 from the fracturing manifold on the fracturing manifold equipment 7. The setting of the protective device 5 separates the fracturing manifold from the gas source delivery manifold 2, realizes the safety protection of natural gas and high-pressure fracturing fluid, and improves the safety of the well site. The protective device 5 is an isolation plate.

[0024] The material of the protective device 5 is steel.

[0025] The gas detection system 4 is a laser gas detection system.

[0026] The gas detection system 4 is a pan-tilt laser gas detection system.

[0027] The pan-tilt laser gas detection system includes multiple scanning laser gas telemeters. The intelligent pan-tilt drives the scanning laser gas telemeters to achieve 360° horizontal and 180° vertical rotation, and conducts multi-dimensional real-time detection of the site. The intelligent adjustment function of the pan-tilt laser gas detection system can realize focused detection areas. The camera simultaneously captures the real-life scene of the site to achieve basic positioning of the leak area. At the same time, the real-time detection data is transmitted to the background analysis system to achieve early detection, early warning, and early treatment of safety hazards, greatly improving the safety protection level of the well site.

[0028] The connecting device 6 includes a connecting pipeline, a valve and a quick interface. The valve is used to connect and disconnect the gas supply of the connecting pipeline, and the quick interface is used to quickly connect the connecting pipeline with the turbine engine. The connecting device 6 makes the gas supply more flexible, changing the gas supply between the turbine fracturing vehicle groups in series in the prior art to parallel gas supply. The running or non-running of a single turbine fracturing vehicle does not affect the gas supply of other turbine fracturing vehicles, and it only needs to turn off the valve and disconnect the quick interface.

[0029] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
