A method and device for in-situ determination of formation thermal parameters, a terminal and a storage medium

Abstract

The application provides a formation thermal parameter in-situ measurement method, device, terminal and storage medium, belongs to the technical field of full well section formation thermal parameter measurement, and the measurement method comprises the following steps: starting a drilling rig lifting device, lowering a sidewall coring instrument to a formation depth to be measured, and drilling a core to be measured by using the sidewall coring instrument; starting a thermal parameter measurement device, heating a resistance wire at a constant power, and measuring a resistance change value of the resistance wire caused by temperature change of the core to be measured; according to a basic physical parameter of the resistance wire, a relationship between temperature change and resistance change, and a mathematical relationship between thermal parameters, core thermal parameters of each test point are calculated, and a formation temperature gradient of a full well section is calculated. The application provides the formation thermal parameter in-situ measurement method, device, terminal and storage medium, which has the technical effects that formation thermal parameters can be measured, a formation temperature gradient of a full well section can be calculated, a formation temperature gradient can be quickly obtained, and a geothermal resource amount can be accurately evaluated.
