The Prediction And Analysis Of Oil And Gas Field Development And Construction In The Whole Process Of Environmental Impact

Nowadays, environmental protection has become a very important factor ofproduction, human life, work in the. At present the environmental protection based onmodern science and technology, in line with sustainable development as theproduction and living environment, providing rich prospects for sustainable andharmonious human society and nature. But in the early70’s of the twentieth Century,a substantial increase in oil production, environmental pollution has been a seriousthreat to the survival of mankind, and by the focus of various countries, manycountries began to study it, and to take appropriate coping strategies. Many countrieshave put their attention on conventional energy saving achieved remarkable results, atthe same time, to realize the importance of the environment, the environmental impactfactors of understanding, understand the importance of each factor is very importantfor today’s environmental issues. As the main body of the oil industry, oil and gasfield development and construction, is a contains a variety of process systemengineering project categories include: ground and underground, the main processincludes the geological exploration, drilling, logging and downhole operation, oilproduction, gathering, transportation and distribution engineering, but in theconstruction stage specific in the influencing factor of environment is not the same.Ten oil and gas blocks house position in Siping City of Jilin Province, the ten oilproduction plant under the house, has four or five subsidiaries, exploration anddevelopment of the eight house, Gu Jia Zi, Qin Jiatun, PI, new legislation in oil andgas field. In order to produce more oil and natural gas, to ease China’s crude oil andnatural gas pressure, to be in the existing ten house area of oil and gas (mainlyinvolves four or five subsidiary, Qin Jiatun, the eight room three block encryption) in45oil and gas wells. Through the analysis of the project, to understand the mainprocess includes the geological exploration, drilling, logging, downhole operation,production, gathering, transportation and supporting the project, to master thesituation of pollutant source, category, release mode. According to the evaluation ofthe selected factors such as SO2,NOx, COD, SS, petroleum, ammonia nitrogen,volatile hydrocarbons were evaluated, and combined with the construction project of the existing atmospheric, surface water, groundwater, noise monitoring resultsanalysis.Prediction of impact of the proposed project construction on the surroundingenvironment, aiming at the construction stage, production stage, close the affectingfactors in different environment well during the three stages of the impact on theenvironment, atmospheric environment of proposed engineering station, gas gatheringstation and gathering the closed process, check and replace wellhead sealing pad andother pollution control measures; the drilling wastewater, wastewater and washingwastewater, gas field wastewater is put forward by analysing the sewage treatmentfacilities, treatment compliance, pollution prevention measures to use; thegroundwater environment present a ground seepage prevention, strengthen therecycling of waste and other pollution control measures; the establishment of muffler,noise shielding devices, mobile reduce the whistle pollution control measures fornoise pollution prevention and control measures to the corresponding project, canensure the pollutant discharge standards. Also different mining produced in theprocess of blowout, fire, explosion, poisoning and other environmental risks, the"guide" construction project environmental risk assessment of HJ/T169-2004in twograde evaluation, analysis and evaluation of the project, the probability is lower thanthe industry standard, the proposed project construction risk within an acceptablerange.
