evaluation of the horizontal wells stage flowback rate using the optical fiber temperature
The flowback rate of horizontal well fracturing stage is an important index to evaluate fracturing effect.At present,tracer method is mainly used for flowback analysis of each stage,but the distribution range,concentration change and unbalanced sampling of tracer in the reservoir may be the major sources of error in this method.In this paper,the initial theoretical ground temperature after pressure is calculated by using the reverse modeling of the original ground temperature,the ground temperature of a certain node at a certain time in the horizontal well flowback stage,and the total flowback amount of a single well.The flowback rate of each fracturing stage of the horizontal well is successfully estimated,which adds a new method for evaluating the effect of reservoir fracturing reform.
