1) cross-borehole observation
井间观测
1.
To cope with the limitation of cross-borehole observation angle, reflection wave is introduced in tomographic inversion.
为了克服井间有限观测角的限制，尝试在层析反演过程中引入反射波信息，并利用VSP观测系统与井间观测系统的相似性，设计了一套地面激发、双井与地面变炮间距接收的地震观测系统，弥补了常规VSP观测信息量不足的缺点，同时较大程度地增加了观测角。
2) crosshole seismic observation
井间地震观测
1.
In recent with the advancement of seismic source and special acquisition equipment manufacturing and their on-going improvement, crosshole seismic observation system and seismic travel time inversion for crosshole velocitymodeling (also tomography) is developing imto a practical technique for reservoir research, description and resolvesome problems concerning reseroir engineering.
近年来,由于井下地震震源和特殊的数据采集设备的研制及不断改进,井间地震观测系统,及其随后的井间速度模型的地震旅行时反演(又称地震层析方法)正在发展成为一项用于储层研究、油藏描述和解决某些油藏工程问题的实用技术。
3) Cross-well survey
井间观测方式
5) borehole observation
井下观测
6) observation well
观测井
1.
The vertical difference of water quality in the observation well is caused by three factors: change of water quality in aquifer during the pumping and injection, the oxidation of the water dody near the surface and the aquifer itself having the vertical hydrogeochemical zones, thus, a dispersion of different concentrations exists.
观测井水质垂向差异由三因素引起:抽、灌水过程中含水层水质改变、近井口表层水体氧化、含水层本身存在水质垂向分带。
2.
The relationship between the drawdown and the time variations defined by the Theis formula was treated as the theoretical true values of the water level changes outside the observation well.
文章针对无界承压含水层中完整井的非稳定流抽水试验,将Theis公式描述的水位降深与时间的变化关系作为观测井外水位变化的理论真值,考虑观测井内外达到水力平衡所引起的滞后时间因素,推导了观测井内水位变化的理论测量值,分析了测量值与真值之间的相对误差以及测量值接近真值所需要的观测时间。
