In recent years, the oilfields in xinjiang rely on environmental protection technology, deftly resolving the contradiction between oilfield development and environmental protection, and oil and gas development and utilization have embarked on the road of green development.
In the "sea of death" taklamakan desert, the northwest oilfield, the second largest oilfield of sinopec, is located there. It is located in the southern xinjiang basin, where the ecological environment is fragile and the economy is underdeveloped.How to explore and develop oil and gas resources while improving the ecological environment is a puzzle.
"As an oil conservationist dealing with contaminated soil, I want to smell the aroma of the soil, not the pungent smell of contaminated soil."Wang jianqiao, deputy director of the environmental protection management department of the northwest oilfield engineering service center, said at the tahe oilfield solid and waste liquid treatment station.
In tahe oilfield solid waste liquid treatment station, the black and brown oil sludge is transferred to the thermal treatment equipment of oil sludge, on the other side, clean soil is continuously produced.The treated soil, which has a minimum oil content of less than 2%, will then be used as roadbed to smooth the well site road.
Nowadays, more and more environmental protection technologies are making efforts to protect the ecological environment of tarim basin from the source and production process.In the first production plant of northwest oilfield, workers have also adopted electrochemical pre-oxidation process to slow down the corrosion of pipelines and equipment caused by acidic sewage.At the same time, after being purified by a new sewage treatment system, all water from the oil field is injected into the original formation.
Xinjiang is rich in petroleum resources, with an estimated oil resource of 22.8 billion tons. However, the ecological environment of the oil-storage desert and gobi region is fragile, and green environmental protection is the premise of development.
In the tarim oil field tower of the taklamakan desert hinterland areas, in the face of the fragile ecological environment, desert oil workers in oil field drilling waste mud does not fall to the ground, take baptism earth thermal desorption and standard innocuity disposal measures, drive to scientific and technological innovation drive from resources, investment, strengthen the drilling, well test, workover, waste management, become "end-treatment" as the "process control", promoting the development of oilfield, green.
"Now we have all the loose gas in storage."Yuan wei, head of the engineering section of the tarim oilfield development department, said that tarim oilfield is the main area of natural gas production, and recovery of scattered natural gas has become the top priority for environmental protection.Since 2000, tarim oilfield has recovered scattered natural gas in different categories, so far collecting billions of cubic meters.
"Green" is not just about exploration and development.According to statistics, tarim oil people planted green fields in the gobi desert covering an area of 482.6 square kilometers, equivalent to 67,000 football fields.Tarim oilfield invests a large amount of funds every year, and basically realizes the green goal of "building a green house and a green district", thus achieving new oases.Only the operation area in the tower, the green area is expanded at the rate of more than ten mu per year.
