| titleOfInvention | Measurement of gas losses in surface circulation system of drilling rig |
| abstract | FIELD: measurement equipment.SUBSTANCE: group of inventions relates to the methods and systems for measurement of gas losses of in the drilling rig surface circulation system. The method of measurement of gas losses on the drilling rig surface includes: adding of pre-set amount of pre-selected gas into the drilling mud on the drilling rig surface; measurement of secondary amount of pre-selected gas in the drilling mud returned from the well without modification of the guiding branch pipe or output mud lines connected to the guiding branch pipe; and measurement of background level of pre-selected gas in the drilling mud; and assessment of gas losses occurring on the drilling rig surface on the basis of pre-set amount of pre-selected gas, of secondary amount of pre-selected gas and of background amount of pre-selected gas. The system for measurement of gas losses on the tank pallet connected with the drilling rig contains the gas measurement system comprising: the probe configured for extraction of the first amount of pre-selected marker gas; a gas analyzer for measurement of the first amount of pre-selected marker gas extracted by the probe; and the software for calculation of the gas losses occurring on the drilling rig surface for comparison of the first value with the secondary amount of the marker gas added to the drilling mud used by the drilling rig, and background level of pre-selected marker gas, and the secondary amount of marker gas is added to the drilling mud without modification of the guiding branch pipe used by the drilling rig.EFFECT: technical result consists in reliable and accurate measurement of gas losses in the surface circulation system of the drilling rig and the gas sampling mechanism.24 cl, 3 dwg |
