Description

Technical Field

[0001] The utility model relates to the technical field of delivery pipe docking, in particular to a delivery pipe docking guide device for oilfield fracturing materials. Background Art

[0002] After the oil well reaches a certain stage of oil production, due to the gravity of the formation, the gaps in the oil layer gradually close, the permeability decreases, and the production capacity decreases. Fracturing is to inject fracturing fluid from the wellhead device into the well through the delivery pipe to create larger cracks in the oil layer, improve the underground flow environment, and improve the oil production efficiency. At present, the docking of the delivery pipe and the wellhead device usually uses a crane to lift the delivery pipe. The lifting position is about 6 meters away from the interface. During the lifting process, due to its own shaking and the influence of airflow, the docking is difficult. Usually, two ropes are tied at the interface of the delivery pipe, and they are manually dragged and adjusted from two directions. For safety reasons, when dragging the rope, the personnel are far away, so the docking is adjusted by manual naked eye observation. The docking is difficult and time-consuming. For this reason, it is urgent to provide an oilfield fracturing material delivery pipe docking guide device. Utility Model Content
