Numerical simulation is of great importance as implementation guides of chemical flooding projects. However, there are still significant difficulties remaining in the historical fitting process of chemical flooding simulation due to uncertainties of some related parameters. In order to enhance the accuracy of historical fitting, the numerical simulation parameters need to be calculated correctly. Based on laboratory experiments of viscosity and concentration curves of polymer solutions, rheological curve, competitive adsorption loss curve between surfactant and alkali, the least squares can be used to establish mathematical models for parameter calculation. On this basis, a software for calculation numerical simulation parameters is developed, and the interface of parameter calculation is realized. Through the application of field historical fitting, the results show that: the performance index calculated by numerical simulation is in very good agreement with the observation data, so a better historical fitting result has been obtained. The accuracy of parameter calculation is verified, at the same time, the time of historical fitting is shortened, which lays a good foundation for predicting chemical flooding performance.

Contemporarily, the random walk is widely applied in the field of finance, suggests that the history stock price has no relation or impact on the stock price tomorrow, i.e., the direction the of stock price is entirely random and unpredictable. This paper investigates random walk simulation in Finance based on the information retrieval and literature review. According to the analysis, if one holds the strong belief in the random walk theory, well-perform ETH or portfolio strongly relevant to core Index (e.g., S&P 500, Nasdaq) will be a proper choice for investors. Otherwise, if one holds that the price movements are inherit connected instead of random variation, statistic evaluation (also known as technical analysis) can be applied to earn with extra returns via time-selection trading actively and positively. Based on enough trials, this paper will try to explore the nature and patterns of random process, which sheds light on future stock price prediction and explanation.
