平凉C11井地下流体数字化观测资料的分析

Analysis on the Digital Observation for the Underground Fluid of Pingliang C11 Well

C11井是甘肃唯一一口数字和模拟观测同时并行的地下流体观测井,2001年9月开始数字观测正式产出资料,与模拟观测相比,数字化观测数据信息量大,传输速度快,人为误差小。该文分析了平凉C11井数字化水位、气压、水温等测项观测资料。结果表明,数字水位动态与模拟水位动态一致性较好、数字水位与数字气压动态之间相关性较好,数字水温与模拟水温的动态一致性不如水位好;数字水位的潮汐效应非常明显,M2波潮汐因子相当稳定(平均值1.1538),相对误差较小(平均值0.0215)。

The Pingliang C11 well is unique one for digital observation and simulation of the under-ground liquid in Gansu province.We can get the digital data from Sep.2001.The digital data have following strongpoints： more information,transmitted more quickly and less artificial error than simulative observation.In this paper,the water level,atmospheric pressure,water temperature data of Pingliang C11 well are analyzed.The results show that the water level data have the good dynamic consistency between the digital data and simulative data.It shows the good correlation of the digital water level and digital atmospheric pressure.The dynamic water level data in the digital and simulative observation are better than water temperature ones.The digital observation of water level is affected by the tidal factor obviously.The tidal factor of M2 is quite stable（the average value is 1.1538）,and the relative error is small（the average value is 0.0215）.
