新探区在未钻井时是没有地层破裂压力曲线的。为此,本文用若干口探井的水力压裂资料来确定新探区地层破裂压力设计曲线的方法,并用此方法对埕岛油田的地层破裂压力设计曲线进行了确定。经验证,该曲线是准确可靠的,说明该方法可行。

The formation fracture profile can’t be available before drilling in a new exploration zone.This article presented a method to determine the formation fracture profile in new zone by use of bydrilitical fracture data of exploration wells.By using this method,the fracture profile have been determed in Cheng Dao oil field.It is shown the fracture profile established is accuracy,reliable and feasibilty through comparing the results with actual data available onsite.
