Using the rock resistivity meter with simulating in - situ conditions, the relations between rock resistivity and temperature were observed from 6 sandstone samples with different porosity and permeability, while samples were brine water - saturated and subjected to certain confining pressure. it is found that the resistivities of water - saturated rock samples decrease in the form of power expression with the temperature increase. although the resistivity of brine water decreases with temperature in the same rule, it can not entirely account for the decreasing of rock resistivity. the cementation factor
利用模擬地層條件巖芯電阻率測量儀，對6塊孔隙度滲透率各不相同的砂巖巖芯，在一定圍壓條件下，巖芯完全飽和鹽水時，考察了巖芯電阻率隨溫度的變化。發現飽和鹽水巖芯的電阻率隨溫度升高，以冪函數形式下降。雖然巖芯中飽和鹽水的電阻率同樣隨溫度以冪函數形式下降，但巖芯電阻率的下降不能完全用巖芯飽和鹽水的下降表徵。This paper researches and analyses the developments of web technology and magnetostrictive transducers from world wide region. the paper also analyes the characteristics curve of magnetostrictive transducers based on its equivalent circuit and researches the method how to make sure its syntony frequency and its electric simulation network parameters. at the same time, by using jsp technology, a magnetostrictive transducer electric simulation application is designed based on b / s three - tier system structure. the experiment data is fitted by curve fitting module. the equivalent input impedance of it with stimulate loop is separated based on the results of curve fitting and the syntony frequency and electric simulation network parameters of magnetostrictive transducers is determined by the input impedance. the method presented in this paper can determine the syntony frequency and electric simulation network parameters of magnetostrictive transducers with a better accuracy than the testing method of syntony & anti - synton y. further more, jsp, the advanced technology at current, has been used to realize a magnetostrictive transducer web electric simulation system. the system has good human computer interface and the function of resource sharing and information publishing. the research of this paper and its achievements have some practical merits in the researchful and applied fields of magnetostrictive transducer
