Waste oil-based mud pollution to the environment has been a national problem, however, petrochina tarim oilfield has to handle the "crack" realize a win-win situation, not only to resolve the waste oil-based mud pollution to the environment, and saving resources, "rich" in the mud in nearly four years nearly one hundred million yuan.
Oil-base mud blood, known as the drilling, compared with the conventional mud, can stabilize borehole wall in oil drilling and improve drilling speed, in super deep well drilling and has been used widely in shale gas development. On the market, the price of every square oil-base mud between 10000 yuan to 13000 yuan.
In order to ensure the stable gas supply to the west to east gas pipeline project from 2010 onwards, the tarim oilfield in kuqa piedmont region started using oil-base mud drilling. By the end of 2016, the tarim oilfield oil-base mud solid waste amounts to 54400 square, if cannot be handled properly, will has a harmful effect on the environment.
To solve this problem, since 2013, tarim oilfield company finally selected by the independent research and development of China's scientific research personnel of the total value recovery of oil-base mud cleaner production and recycle technology ". In October 2013, in tarim oilfield, built the first recycling treatment station in the deep areas focus on two big north, deep oil-base drilling solid waste gas field.
Is responsible for the concrete implementation of xinjiang bazhou Zhang Cong, manager of the new environmental protection technology co., LTD., said that processing technology by physical methods, neither expensive in the destruction of oil-base mud drilling additive performance, can realize the separation of sludge and solid waste at the same time, "only to produce qualified oil-base mud and clay two products."
By the end of 2016, the tarim oil field processing oil-base mud solid waste 46700 square, recycling unqualified oil-base mud more than 9000 square, reduce the cost of single well oil mud of 20% to 25%.
The xinjiang uygur autonomous region environmental monitoring station monitoring, processing after the solid content of oil content is better than that of the state environmental protection standards, indicators of heavy metals in accordance with the soil environmental quality standard, solves the problems in the process of using oil-base mud pollution.
