PRESSURE RESPONSE FRACTURE PORT TOOL FOR USE IN HYDRAULIC FRACTURING APPLICATIONS |
摘要 |
A pressure response fracture port tool and method for its use reliably provides a noticeable indication at surface to an operator as to when the flow port is opened. The tool includes an outer housing and a sliding sleeve which resides within the outer housing. The outer housing has a first and second set of flow ports. The inner mandrel moves between a first position and a third position to expose the flow ports to the wellbore. The first set of flow ports, with its smaller area relative to the second set of flow ports, creates a noticeable pressure increase or spike that can be observed at surface when exposed to the wellbore. The second set of flow ports creates a noticeable pressure drop when it is exposed to the wellbore. |
