渤南油田深井压裂试验的地下水动态观测与初步研究

在一口石油深井的压裂试验过程中,观测了井孔地下水压力、流量与温度动态的反映,结果表明同层地下水动态反映明显,流量的反映幅度大于压力,由此提出在地下水动态反映含水层应力应变的机理中,水动力学过程的重要性;水动力学机理中两种信息传递方式及流体介质传递方式的重要性;对同一个应力应变过程流量的反映更优于压力的反映等观点

OBSERVATION AND STUDY OF GROUNDWATER UNDER HYDROFRACTURING EXPERIMENT IN A DEEP WELL IN BONAN OIL FIELD

The pressure, flow rate and temperature of groundwater at the heads of two deep wells have been observed under hydrofracturing experiment in an oil well. The result shows that the response of groundwater behaviour in the same layer in these observed wells to hydrofracturing process is obvious. The response of flow rate is more significant than that of the pressure. On the basis of these results, the authors suggest the significance of hydrodynamic process in the mechanism of responce of groundwater behaviur to stress-strain of aquifer, the more important role of fluid movement than pressure transmission in the hydrodynamic mechanism, and the more obvious response of flow rate to the same stress-strain process in an aquifer than that of pressure.
