Testing of the Theoretical Model for a Wieeband Pulse Propagation in the Oil-Gas Collector Media

摘要

Recently, there were carried out [1] experiments on propagation of a quasi plane pulse wave through the rock fiu1Dized with oil and saline water. The results of [1] can be used to test the theoretical model [2, 3] of ultra w1Deband (UWB) pulses propagating through the structures used in [1]. Using the methodology of [2] and [3], the shape and analytical signal amplitude of the pulse transmitted and reflected as in [1] were calculated, with the error of theoretical simulations being estimated. The standard deviation of the simulated values from those measured appeared to be of 11.5% and 8.2%, respectively, concerning shape for the pulse transmitted, through a rock layer fiu1Dized with oil and water, and reflected from two bordering on each other layers, one of which being fiu1Dized with saline water and the other with both the saline water and oil. In the case of pulse propagated though the rock layer fiu1Dized with saline water and oil, a simulation error was found to be of 3.7%, as determined for the analytical signal amplitude. The simulation errors obtained have to be limited to a short propagation distance of only 5 cm.
