The loess plateau in the block of the first oil production plant is dry and less rainy, and ecologically fragile.
Protecting the ecological environment is the primary task and primary responsibility of oilfield development
.
In recent years, the No.
There are 7 oil wells in the HH1054 wellsite of the second oil production management area of the first oil production plant, with a daily oil output of 5.
08 tons, and the 7 oil wells have different degrees of associated gas surplus.
Therefore, the management area installed gas generators on the wellsite and supported them.
The grid-connected and non-connected control system connects the casing gas of 7 oil wells in series, so that the associated gas is collected to the gas generator through the gas distributor and the dryer
.
Associated gas "particles return to the warehouse", as the combustion kinetic energy of the gas generator, to ensure the power operation of the entire well site
After a period of observation, the management area has worked out a set of associated gas utilization rules, and the gas generator can be used for 12 hours every time the casing is held down for 24 hours
.
From January to July 2021, the gas generators will operate for a total of 1,670 hours, saving 46,800 kWh of electricity and saving electricity costs of 36,500 yuan
Associated gas, which has always been regarded as "exhaust gas", has now become a good treasure.
In the JH17P11 well site of the fourth area of oil production management, equipment operation, oil dehydration, and domestic electricity use all benefit from the associated gas
.
Before April 2020, the electricity used for production and life at the well site came from the local rural network, and it often encountered problems such as electric circuit failure caused by wind and rain or maintenance of circuit aging, which caused a lot of inconvenience
.
After that, a multi-functional tank was installed at the well site, and part of the separated associated gas was used for boiler heating, heating the oil storage tank coils to speed up crude oil dehydration; the other part was filtered into a two-stage gas bag to be used for gas-fired power generation Machine operation guarantees 24-hour production and life at the well site
At present, the first oil production plant has installed a total of 18 natural gas generators, the associated gas recycling rate reached 85%, and the annual reduction of exhaust gas emissions was about 10.
5 million standard cubic meters.
Associated gas turned waste into treasure, realizing a win-win situation for green production and energy saving
