Between horizontal wellbore.Pressure break horizontal well temperature profile this small temperature difference can be recognized by DTS technologies, such that it is able to reality
Existing man-made fracture location determination.If the temperature difference under different fracture parameters can be measured, temperature just can be found by quantitative analysis
The relation of difference and man-made fracture parameter, this also for using DTS technologies carry out pressure break horizontal well crack Diagnosis provide theory according to
According to.At present, fracturing transformation effect test is generally carried out using modes such as micro-seismic monitoring, production loggings and man-made fracture is diagnosed,
But these conventional meanses are costly, operation is complex, and can not immediately arrive at accurate man-made fracture parameter.And
