METHOD AND COMPOSITION FOR DETERMINING GEOMETRY OF CRACKS OF UNDERGROUND STRESSES

摘要

1. A method of treating an underground formation, including: a) placing proppant and / or hydraulic fracturing fluid in the fracturing fracture, including the radiation-sensitive material, where the radiation-sensitive material is a non-radioactive material; b) placing the logging probe in a specific position so so that it is near at least one part of the formation fracture after placing the radiation susceptible material in the formation fracture, where the logging probe includes a first detector, a neutron emitter and a second detector; c) measurement of gamma radiation emitted from at least one part of the fracture formation using the first detector during the first period of time; d) the location of the neutron emitter so that it is close to at least one part; e) irradiation of at least one part of the formation fracture for a second period of time; f) the location of the second the detector so that it is close to at least one part and formation fractures; g) measuring gamma radiation emitted from any irradiated radiation susceptible proppant material and / or fracturing fluid located in at least a first portion of the formation fracture for a third period of time; and h) subtracting gamma radiation emitted from at least one part of the formation fracture from gamma radiation emitted from the irradiated radiation-receiving material of at least one part of the formation fracture, in which all stages b) to h) are performed in a single descent logging probe lifting. 2. The method of claim 1, further comprising: i) determining a height �
