通过分析不同压裂裂缝监测方法对裸眼水平井压裂缝高的确定作用,将套管完井的直井井温测井数据和裸眼水平井压裂地面微地震监测数据相结合,提出了裸眼水平井压裂裂缝高度计算模型,并给出了模型有效性的验证方法。最后,通过现场实例对该模型进行了验证。实例表明,该模型可以较为准确地对裸眼水平井压裂缝高进行预测,对裸眼水平井压裂优化设计具有实际的指导作用。

The Determination for Fracturing Fracture height of Open Hole Horizontal Well

This paper combined different monitoring methods to provide valuable information regarding hydraulic fracturing fracture height of open-hole horizontal wells. By analyzing temperature logging data of large cased vertical wells, the relationship of fracture between height and rate of injection of construction can be established. The accuracy of the equation has been proved by down-hole microseismic monitoring data which is the most reliable method in recent monitoring field. Uniting the micro seismic monitoring data of open hole horizontal wells and temperature logging data of cased vertical wells, the height equation at different injection rate of open hole horizontal wells can be obtained, which is helpful for fracturing optimization design of open hole horizontal wells.
