摘要
压裂施工前,随压裂管柱将可存储式温度压力计下入到目的层,可完整记录压裂施工全过程的井底温度、压力变化情况。由此,可根据测试资料分析评价影响压裂施工的因素,准确计算压裂液在管柱中的真实摩阻,确定压裂的压力等级和裂缝的温度剖面,指导压裂设计,为优化设计提供可靠依据。
Before fracture operation, the memory T & P gauge can wholly record change of down hole temperature and pressure that is lowered to objective formation with fracture testing string. Based on analysis of testing data interpreting the influence on factor of fracture operation, true friction of fracture fluid in stem is calculated accurately, pressure grade of fracture and temperature profile of crack are determined which direct fracture design and provide a reference for optimum of it.
