摘　　要：大通径压裂管柱能明显减少管柱摩阻,降低施工泵压,以及提高压裂作业效能。根据江汉油田的油井生产状况和地层特点研制的大通径压裂封隔器及管柱,能很好地与井下Φ88.9mm油管(内通径76mm)相配套,无须球座封。Pipe strings of large drift diameter fracturing can obviously decrease pipe string friction, resistance and pump pressure in construction as well as enhance operating efficiency of fracturing. The packers and pipe strings of large drift diameter fracturing developed according to the oil well production situation and stratum property of Jianghail Oil Region can match the downhole oil tubing of Ф8. 9mm（inside drift diameter76mm） perfectly without ball sealing.
