Description

technical field [0001] The invention relates to the field of fracturing equipment, and more specifically, to an oilfield manifold system and a fracturing equipment set. Background technique [0002] Fracturing operation is one of the important means to transform oil and gas reservoirs. For low permeability oil and gas wells, it is generally necessary to rely on fracturing operations to achieve the purpose of stabilizing and increasing production. Fracturing construction cooperative operation equipment generally includes water supply truck, sand mixing truck, manifold system and fracturing truck. Participate in mixing the fracturing fluid in the mixing tank, and pump the fracturing fluid prepared in the mixing tank to the plunger pump of the fracturing vehicle. At present, the scale of fracturing construction is increasing day by day. In order to improve the efficiency of fracturing construction, usually one sand mixing truck supplies fracturing fluid to multiple fracturing ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned manifold system can meet the needs of general-scale fracturing construction. However, when the scale of fracturing construction increases, more fracturing trucks are required to operate at the same time, and a manifold system with a larger displacement needs to be equipped for more The fracturing truck on the platform supplies fracturing fluid, while the current manifold system is limited by the power of the suction pump and discharge pump, and the maximum clean water displacement is generally 16m 3 / min, the maximum displacement of fracturing fluid after mixing proppant is still less than 16m 3 / min, which cannot meet the needs of large-scale fracturing construction

At present, in order to make the displacement of the manifold system meet the needs of large-scale fracturing construction, two methods can be adopted: one way is to configure the manifold system with higher-specification suction pumps and discharge pumps, and higher-specification The price of the suction pump and discharge pump is relatively high compared with the pumps of ordinary specifications, resulting in a substantial increase in equipment costs and affecting the benefits of construction operations, and the increased displacement of pumps with higher specifications is also limited; another The first way is to add a set of sand mixer and manifold system, and the cost of sand mixer is more expensive, which has a greater impact on the cost and benefit of fracturing construction
