| titleOfInvention | Method and system for testing oil-gas-water profile of each section of horizontal well by using environment-friendly tracer |
| abstract | The invention provides a method and a system for testing the oil-gas-water profile of each section of a horizontal well by using an environment-friendly tracer, wherein the method comprises the steps of determining the type and the combination of a chemical tracer according to information comprising the type of an oil-gas reservoir, the type of a fracturing fluid and the number of testing sections; determining the design dosage, injection time and injection flow rate of the chemical tracer used in each section; determining tracer injection equipment used for testing and confirming that the arrangement of the tracer injection equipment is completed on-site operation equipment connection flow before construction; completing the injection operation of the corresponding chemical tracer required by the construction section according to the designed pump injection program; after fracturing construction of the whole horizontal well is finished, continuous tracer test sampling operation is carried out according to designed sampling time and frequency, and samples are detected in time after all sampling is finished; and drawing a production profile or contribution ratio graph of each interval fractured by the horizontal well of the oil and gas reservoir in a sampling period. |
