By taking the oil & gas drilling characteristic, environmental feature, environmental protection of drilling practice and cleaner production status as starting point, in line with relative requirements of environmental protection and cleaner production regulated by State and CNPC, this paper discussed environmental risks faced in drilling practice of in Sichuan and Chongqing District. Furthermore, on the basis of detailed analyzing basic conditions of drilling screws, from drilling anti-pollution facilities and eight main production processes,this paper proposed relevant cleaner production measures and improved steps of anti-polluted construction control during drilling progress, put forward corresponding treatment technology for pollutants brought from drilling in Sichuan and Chongqing District, furthermore proposes serials of encouragement for the cleaner production of continuous drilling, introduces cleaner production methods of relative demonstration well. Taking advantage of the research achievements in cleaner production well for the design and implementation, which have achieved great progress. What this paper researched on would be helpful to administrators of drilling environment management in Sichuan and Chongqing District. |
