Fracturing Manifold
The manifold has multiple interfaces that can be connected to the fracturing truck. The high-pressure pump group on the fracturing truck is used to inject fracturing fluid into the well at high pressure, high speed, and large displacement through the fracturing manifold. By relying on the pressure transfer function of the liquid, when the injection speed of the high-pressure pump group is greater than the suction and filtration speed of the formation, a high pressure is formed near the formation. When this pressure exceeds the tensile and compressive strength of the formation rock, the original fractures of the formation will expand, Forming larger cracks or creating new cracks. With the continuous injection of high-pressure and high-speed liquid into the high-pressure pump group, the fractures in the formation will continue to expand and extend until the injection rate of high-pressure liquid is equal to the infiltration rate of the formation. To prevent these fractures from re closing after the pump stops on the ground, a certain proportion of proppant is added to the injected fluid and filled in the fractures to achieve fracturing effect. Each branch has a plug valve and a single flow valve to cut off or open the corresponding branch in one direction.
