The Distribution Characteristics Analysis of Pollutant Atrazine in the Petrolic Drilling Fluids
In view of the present situation that a lot of waste drilling fluids pollute soil and water in the process of petroleum exploration and development, choosing the drilling fluids in the 5 well field which is in the North area of ChangQing oilfield to carry on the pollution characteristic analysis. 39 physicochemical indexs and contamination indexs had been determined in the drilling fluids,its result is: the waste drilling fluids are ropiness colloid, paste, viscosity high. The drilling fluids ingredient is clay, polyacrylamide(PAM),carboxymethylcellulose(CMC).CODCr,mineraloils,NH4+,Cr,Cd,Pb,As,pH,chromatici ty and so on exceed standard in the drilling fluids,Zn exceeds standard in some individual well fields, the other over-standard parameterssuperstandard multiple is not big except CODCr,mineral oils which exceed standard siriously . CODCr,mineral oils,NH4+ and so on are from formation petroleum and the additives such as polyacrylamide (PAM), carboxymethylcellulose (CMC).etc,high pH is related to calcined soda or caustic soda, Cr、Cd、Pb、As、Zn and so on are from the sidewall material which is cattied by the circulating Cd As mud,which are related to formation lithological composition.
