Design and study of large-scale offshore fracturing surface process
Offshore low permeability oil field has been the main areas in increase reserves and production,large-scale fracturing can realize the thorough transformation of low permeability reservoir,but offshore fracturing operations with small area,mud pool capacity limited,limited equipment capacity,after multiple well offshore fracturing practice,fracturing process to distinguish the main process,standby process,and distinguish between high pressure and low pressure area.In addition,the use of seawater base fracturing fluid with continuous mixing construction technology,it is preferred to quickly change the seawater base fracturing fluid,save the deck space of the fracturing fluid,and fracturing the formation under multiple fracturing pumps.In order to ensure the safe and efficient fracturing operation,the low pressure area is set to reduce the use of reducing joint and elbow to reduce the vibration of the ground pipeline.At the same time,emergency sand drainage pipeline is provided in the process of fracturing pump to form a large-scale fracturing continuous mixing of sea base fracturing fluid technology,to provide reference for the design of large-scale fracturing ground process.
