Recently, the construction site of the third-phase production and capacity expansion project of the Southwest Oil-based Cuttings Processing Station of Jianghan Petroleum Engineering Environmental Protection Technology Service Company was busy.
The company independently designed and customized 6 sets of new environmental protection devices-rotary furnace The installation is about to be completed in the Fuling shale gas field.
After commissioning, the annual processing capacity of oil-base cuttings will be greatly improved, and the efficiency will increase by 60%
.
Rotary furnace has the advantages of less investment, lower operating cost, stronger adaptability, and wider processing range.
The flue gas and exhaust gas treatment system is added to treat the flue gas more thoroughly and reduce environmental pollution; the thermal efficiency is higher, and the same Under the conditions, the heat consumption is smaller, the processing of oil-base cuttings per cubic meter reduces the electricity consumption by 60%, the gas consumption by 40%, and the carbon emissions by 15%, providing a stronger green support for the exploration and development of the Fuling shale gas field
.
Oil-based cuttings are a kind of oil-bearing solid waste generated when oil-based drilling fluid is used to open the oil and gas "passage" during the exploration and development of shale gas fields.
If harmless treatment is not carried out, it will cause serious pollution of the oil and gas field environment
.
In the early stage of gas field development, oil-based cuttings are a new thing, and the treatment methods and methods are blank in China.
Since 2013, the environmental protection technology service company has established an oil-based cuttings processing center, researching on the harmless treatment of oil-based cuttings, independently researching and developing a unique thermal distillation process, and manufacturing a device that meets the process requirements.
The furnace has realized the harmless treatment of oil-based cuttings, filling the gap in the technology of large-scale harmless treatment of oil-based cuttings during the development of Sinopec’s shale gas
.
In 2015, the company launched the second phase of construction.
Nowadays, the construction of shale gas fields has been accelerating, the drilling speed and efficiency have been improved, and the output of cuttings has increased rapidly.
In order to ensure the smooth progress of the expansion project, in view of the frequent thunderstorms and the dense rocks in the Jiaoshi block, it is extremely difficult to level the mountain.
