Description

Technical Field

[0001] The utility model relates to the technical field of oilfield gas generator sets, in particular to a skid-mounted box and a skid-mounted oilfield gas generator set. Background Art

[0002] At present, most of the power supply for oilfield drilling rigs is powered by diesel generator sets. In order to achieve carbon neutrality and reduce carbon emissions, it has become a trend to use gas-fired units to replace diesel generator sets, that is, gas replacing oil. During the operation of oilfield drilling rigs, the impact load is large. The current dynamic response of a large-power single gas-fired unit cannot meet the impact of the drilling load of the drilling rig. At the same time, if a large-power single unit is used, the unit power needs to be amplified. However, the actual operating load rate is low, and the gas-fired power generation conversion efficiency is low, which is not economical. Therefore, a container gas power station power supply technology that is powered by small-power gas-fired units in parallel can effectively solve the problem of low gas-fired power generation. This product uses 4 250KW small-power gas-fired units in parallel, integrated in a container, and automatically adjusts the number of units in operation according to the load size on site, which reduces the number of units in operation to achieve the purpose of improving conversion efficiency. At the same time, multiple units are operated in parallel, with fast dynamic response speed, and can cope with sudden loads well. Utility Model Content
