摘　　要：随着人类工业文明的不断发展,石油成为重要的化工资源。然而,石油开采带来的负面影响却日益凸显,如环境污染、资源枯竭、开采安全问题等。由石油开采导致的地面沉降则是这些问题里最不容忽视的,石油开采会导致油层中地下压力的减少,造成油层的紧密压实。当压密的数值达到一定量时,就会引起地表下沉。在城市区域内,地表形变会影响各种生产设施的安全使用。本文以国内某油田为试验对象,利用短基线集技术(SBAS)进行处理,对石油开采时引起的地表沉降进行监测,综合分析其地表形变速率、范围,以及地面变形影响因素,为生产单位和当地政府部门提供决策依据。With the development of the industrial civilization,the petroleum has become more and more important in the chemical industry. However,the negative impact of oil mining has become increasingly prominent,such as environmental pollution,resource depletion,mining safety issues,etc. The surface subsidence caused by oil exploitation is the most important problem,resulting in the decrease of the underground pressure in the oil layer,which leads to the compaction of the oil layer. When the quantity of the intensity of pressure reaches a fixed value,it will cause the surface subsidence. In the urban area,surface deformation will affect the safe usage of various production facilities. This paper takes an oilfield as the study object,using SBAS technology（small baseline subset） to monitor the surface subsidence caused by implementation of oil production activities. Eventually it provides a comprehensive analysis of the phenotypic variable rate and scope,ground deformation factors and the basis for decision-making for the production sectors and government departments.
