钻井泥浆固化处置对土壤环境的影响

针对四川地区油气田产生钻井废泥浆的特点，选取代表性的井场平台，进行现场调查和固化体取样实验，并将量化的数据定性化，得出固化处理钻井废泥浆对环境影响的程度，再通过对较差的井场进行土壤环境质量监测，最终分析钻井泥浆固化处置对土壤环境的影响及应采取的相应措施。结果表明：采取废弃泥浆固化方法效果较好，对周围土壤环境影响小。

The Impact of Solidification Treatment of Drilling Mud on Soil Environment

In this paper, representative well sites are selected at natural gas exploitation area in Sichuan region for site investigation and sampling of solidified body, and the leach liquid of the body was tested and monitored. The mathematic model is established. After that, the impacts of leach liquids of well sites on edatope are obtained from quantitative data standardization by analytic hierarchy process (AHP). Then, the impacts of drilling mud solidification treatment on edatope and corresponding measures are finally analyzed by carrying out edatope quality monitoring at the well sites with poorer soil environment.
