A Research Of Ecological Environment Impacts And Ecological Restoration Measures On Gas Field Exploitation

The oil and gas resources is an important lifeline of the national economy, oil and gasresources in the creation of huge social and economic benefits to the society at the same time,also caused some environmental pollution and ecological destruction. Because the gas fielddevelopment is the network structure, a variety of ecological system of single well punctatedistribution, planar distribution properties of group wells on the zone of interference, complexand diverse influence. The ecological environment the most obvious impact including theexpropriation of land, destroy the surface topography, soil erosion and desertification inducedby changing the types of natural vegetation or vegetation destruction, to change the surfacerunoff, effects of wild animal habitat, reduce species diversity, the destruction of the naturalecological balance, hinder the normal succession of ecological system. Therefore, for thedevelopment and construction of the fragile ecological environment area of oil and gas field,to take measures to protect the environment more strict.This article to the Maowusu Sandy Land in Northern Shaanxi Province typical gasproject as an example, based on the two detailed field survey in2012, April and August, thefull collection of historical data, monitoring data and other related information, and acomprehensive analysis of the gas field exploitation engineering characteristics, from theimpact on vegetation, wild animal, soil, soil erosion, measures to restore the ecologicaldisturbance on the area of the proposed during the construction of ecological protection andconstruction, lists the measures of ecological protection and restoration, to protect the fieldecological environment, promote the sustained and healthy economic development of gasfield, realize the development of resources and coordinated development of ecologicalenvironment protection, avoid and reduce the ecological environment destruction.The research results obtained are as follows:1through field investigation and collection of existing data, the ecological environmentbackground knowledge of gas system, such as geological and geomorphological, ecologicalregionalization, vegetation, animals and plants, soil etc..The2analyses the present situation under the conditions of the environment, ecologicalimpacts caused by gas field. Ecological impact are: the effect of land use, soil properties and the effect of the ground vegetation, wild animals and plants.3covers an area of, from the case field engineering site, station, gas pipeline, with road,influence of mud debris on the ecological aspects, analyzes the corresponding measures forecological protection, and gives the conclusion and other concerns or suggestions. Ecologicalprotection and restoration measures for optimization, a reasonable construction plan,strengthen the management of environmental protection engineering, restoration of vegetation,wildlife protection, prevention of soil erosion, prevention and control of soil erosion.Through this research can determine the main content of the work, in the ecologicalprotection work gas field project in solving some problems, and provide the reference for theconstruction unit, also has an important significance to environmental protection, healthydevelopment of gas field exploitation.
