Beneficial effects of the present invention are：It is of the present invention to utilize Uranium determination agent level monitoring well staged fracturing effect
Methods of optimization design links, it is all linked with one another, include selection and the dosage of tracer, tracer scene injection mode,
The frequency and sampling period, tracer concentration for returning drain sampling change over time Drawing of Curve and tracer detecting instrument, make
The data obtained, which have, to be ensured, it is ensured that the accuracy of each section of tracer concentration contribution data can specify each fracturing section production
It has troubles.
It is described as follows：(1) before scene note tracer, first to target well water sample detection, background is selected according to result
The low trace element of concentration is originally present in interference micro- in stratum as tracer, from reducing on source, more
Science, when late detection tracer concentration, are more accurate, while clearly referring to when drawing tracer concentration and changing over time curve
Go out the original amount of tracer in the background concentration i.e. water flooding for need to mark tracer, fully considering background concentration, this is heavy
Parameter is wanted, background concentration is effectively prevented and causes monitoring result inaccurate, lead to the problem of the fracture pattern inaccuracy of analysis.
(2) prior art is then mainly determined tracer dosage, the meter involved in formula by maximum dilution volumetric method
Calculation parameter is more, and parameter drainage area, core intersection determine there is certain error by log；The detection spirit of parameter tracer
Sensitivity is a range, different instruments, sensitivity difference；Parameter surplus coefficient is empirical parameter, and value is also a range, because
The value of most parameters changes in an interval range in this formula, and it is also a range to lead to the dosage of tracer, and
It is not a concrete numerical value；And the dosage of tracer of the present invention depends on the volume of prepad fluid, load fluid when site operation
And tracer when being evenly distributed on prepad fluid and load fluid these three parameters of the concentration of trace element, three parameters be all to determine
Numerical value, calculate the numerical value that the dosage of tracer is also to determine, rather than a range, tracer decreased while accurate
The dosage of agent effectively eliminates limitation and interference of the detecting instrument to test result.
While tracer is evenly distributed on the concentration in prepad fluid and load fluid and is set to 500 μ g/L by the present invention, is fully examined
Tracer has a small amount of adsorption loss when considering site operation, and different type tracing agent adsorbtion loss amount is different, horizontal well point
