Description

Technical Field

[0001] The utility model relates to the technical field of manifold devices, in particular to a fracturing construction manifold device. Background Art

[0002] Fracturing construction is one of the important measures to increase the production of oil and gas wells. It uses hydraulic action to form cracks in the formation, thereby improving the permeability of the formation and increasing injection and production. Fracturing mainly uses a ground high-pressure pump truck group to inject fluid into the well at high speed. With the help of the high pressure built up at the bottom of the well, the oil layer rock is broken and cracks are generated. In order to prevent the pressure from dropping and the cracks from closing on their own after the pump truck stops working, sand (proppant) with a density several times greater than that of the formation will be mixed into the injected liquid after the formation is ruptured. The sand will enter the cracks together with the fluid and stay in the cracks permanently, supporting the cracks in an open state, so that the oil flow environment can be improved in the long term. The fracturing construction manifold is a ground tool that connects the ground pipeline to multiple fracturing trucks. It is mainly used to collect the liquid pumped by the fracturing truck and inject it into the target layer of the fracturing well. However, in fracturing construction technology, the existing manifold devices are mostly single-main line designs, which limit the ability to handle a large number of temporarily blocked particles. When the number of particles is large, the particles need to be dropped in batches to avoid blockage. This not only prolongs the construction period and reduces efficiency, but also makes it difficult to meet the needs of large-dose treatment, restricting the flexibility and efficiency of the technology. Utility Model Content

[0025] It can be understood that when the utility model is installed, the adjusting bolt 21 is rotated, and the adjusting bolt 21 is rotated to drive the fixed pressure plate 20 to adjust the position inside the fixed top frame 18. The bottom of the fixed pressure plate 20 presses the No. 1 multi-way pipe 1, the No. 2 multi-way pipe 3, and the connecting pipe 14 between the supporting base 16, and is inserted into the ground through the fixed plug rod 17 for stabilization. The low-pressure plug valve 2 and the No. 2 multi-way pipe 3 are injected through the No. 1 multi-way pipe 1, and the No. 2 multi-way pipe 3 and the main pipe 6 are injected through the booster inlet pipe 4. The pressurized treatment is carried out, and the flow is diverted through the No. 1 branch pipe 5, the No. 1 stopcock valve 7, and the No. 2 branch pipe 8. The total amount of temporary plugging particles is increased through the stopcock valve on the No. 2 branch pipe 8 to meet the construction demand of a large amount of single-layer temporary plugging particles in the conventional temporary plugging process. The particles are added into the No. 2 branch pipe 8, the No. 3 branch pipe 10, and the No. 4 branch pipe 12, and then enter the connecting pipe 14 through the No. 4 branch pipe 12, and are merged into the connecting pipe 14 through the main pipe 6 for centralized merging, and pressure-collecting treatment is carried out through the pressure-collecting fracturing pipe 15.

[0032] See also Figure 1 and Figure 3 A plurality of fixing rods 17 are symmetrically fixed to the bottom of the support base 16 .
