METHOD FOR INTERPRETING WELL YIELD MEASUREMENTS DURING WELL TREATMENT

摘要

FIELD: oil and gas industry.SUBSTANCE: method includes stages whereat arrangement of drill string lower part (ADSLP) is placed in the borehole. At that ADSLP contains an injection port for delivery of fluid to the wells, the first sensor placed above the injection port and the second sensor placed below the injection port. Each sensor out of the first and second sensors generates feedback signal representing the rate of fluid flow at the borehole section. Approximate depth of ADSLP is measured in the borehole. Data model is formed on the basis of a set of instructions, at that the data model represents characteristics of fluid flow in the borehole; moreover the data model is received against feedback signal and approximate depth of the injection port. The data model is analysed for the purpose of extrapolation of the formation characteristics.EFFECT: efficiency of simulation treatment due to received knowledge on distribution of flow within the operating range in real time.20 cl, 3 dwg
