The uncertainty of the interwell reservoir interpolation based only on well data can be decreased by comprehensive utilization of geological, logging and seismic data, especially by using highly relative seismic properties from 3D seismic data adjusted by well point data to restrict interpolation of geological properties.

Through analysis of the water resources in Beijing from 1980 s up to now, this paper finds the major problems in the exploitation and utilization of groundwater in Beijing lie in the over-exploitation and pollution in groundwater, which are primarily caused by the rapid growth of population, enduring imbalance between exploitation and replenishing of groundwater and the contamination of groundwater. Thus based on this, this paper puts forward proposals and opinions to exploit groundwater in a scientific and moderate way, and to comprehensively protect the groundwater resources and environment in Beijing.展开更多
