Evaluation on Effects of Oilfield Roads on Soil and Water Conservation Function
[Objective] In order to provide a calculation basis for the standard of soil and water conservation compensation fees for oil and gas projects
the values of water and soil conservation function loss due to oilfield road pressure and hardening during production period were quantitatively evaluated.[Methods] The ecological service value evaluation method was used to estimate the loss value of the soil and water conservation function of oilfield by calculating the model of the oilfield in Zhidan County of Shaanxi Province. According to this method
the value of soil and water conservation function is equal to the sum values of holding soil
water conservation
carbon fixation and oxygen supply
air purification
wind and sand fixation
and biodiversity maintenance.[Results] Roads in oilfield can reduce the value of the soil and water conservation function
the average annual loss of soil and water conservation function of each well reached 1 827 yuan. According to 30%~50%
usual proportion of the road area to total area of oil field
the average annual loss of soil and water conservation function of each well was 3 654~6 090 yuan higher than the current standard which is not more than 2 800 yuan.[Conclusions] It is reasonable and feasible for the current method of soil and water conservation compensation to be collected according to the year and the standard of collection(no more than 2 800 yuan per well).
