Financial Risks of Technology-based SMEs and Countermeasures HUA Dongling 2023, 50 (10):  22-24.  Abstract ( 476 )   Save The solvency of enterprises is the presentation and root of financial risks. In recent years,technology-based small and medium enterprises have developed quickly. Realizing the risks of these enterprises can help to keep China’s financial system stable and boost the development of technology-based SMEs. Risks faced by technology-based SMEs are debt and liquidity risks. Besides,based on the features of technology-based SMEs,they also suffer from higher systemic and non-systematic risks. Pressure from the macro-economy,difficulty in the financing,the technology blockade from abroad,the lack of a creditworthiness system of technology-based SMEs and macro-economic policy’s crowding out effect are reasons for financial risks. To reduce the financial risks,the policymaker can set local government technology-based SMEs’ investment funds,establish technology-based SMEs’ reliable creditworthiness system,offer financing platforms and plans for these enterprises,carry out structured monetary and fiscal policies,classify and dispose of non-performing loans of technology-based SMEs.

Study on Water Flooding and Key Development Indexes of Thin Interbedded Reservoir WANG Xinpeng, PANG Weihao, SHI Hongfu, ZHANG Wenjun, ZHENG Jinding 2023, 50 (10):  28-31.  Abstract ( 440 )   Save As a whole,P oilfield is a typical thin interbedded reservoir,which is characterized by uneven reservoir thickness,thin layer development,rapid lateral change of reservoir,poor reservoir connectivity,and less testing and production performance data,so it is difficult to predict the real water flooding degree. The corresponding rate of injection and production in water flooding reservoir directly determines the water flooding degree,which has an important impact on the prediction accuracy of key indicators such as recovery rate,decline rate and water cut rise rate. Based on the comparison on the geological fine layers,starting from the injection production corresponding rate of thin interbedded reservoirs,the average static injection production connectivity rate of the oilfield is about 75%. Further analysis of the pressure measurement while drilling data and actual production data shows that the actual dynamic injection production corresponding rate of the reservoir is 70%. Through the establishment of a typical numerical model which can represent the geological characteristics of thin interbedded reservoir,the influence of injection production corresponding rate on decline rate,recovery rate and water cut rise rate is judged. The results show that under the same liquid production rate,the higher the injection production corresponding rate,the smaller the decline rate;On the contrary,the greater the decline rate. With the increase of the injection production corresponding rate,the oil recovery rate and water cut rise rate are also increased. References | Related Articles | Metrics
