Based on the adjacent tunnel between Shuigou River and Songjiawa, this article evaluates and optimizes traditional lighting schemes and sunshade schemes from the above three aspects. The results show that the overall uniformity of road surface luminance for both schemes is greater than 0.313, which meets the regulatory requirements and is a feasible solution. Compared to traditional lighting schemes, the sunshade scheme reduces carbon emissions by 37.23% throughout its lifecycle, and reduces the present value of its lifecycle costs by 19.51%.

A geological model of heterogeneous coalbed methane reservoir is established, which includes igneous rock and fault geological structure. The influence of permeability on coalbed methane productivity and reservoir pressure under complex geological conditions is studied by numerical simulation. The results show that the permeability of coal seam is an important factor affecting the yield of coalbed methane. The higher the permeability, the faster the output rate of coalbed methane, the higher the output, the faster the pressure drop of coal reservoir, and the faster the desorption rate of coalbed methane. Under the premise that the horizontal wellbore is perpendicular to the maximum permeability direction of the coal seam, the productivity of the well arrangement method is higher than that of the parallel maximum permeability direction. However, the length of the horizontal well in the Liujia block is limited by the dense igneous rock distribution, and the desorption area of the coalbed methane is reduced and the production is reduced when the vertical arrangement is arranged. Therefore, the horizontal wells in the Liujia block should be parallel to the maximum permeability direction and set along the direction of igneous rock.

Wellbore barriers, such as tubing, casing, and cement, are the primary components that prevent the undesirable flow of subsurface fluids. However, due to the complexity of the operating condition in a harsh environment, the tubing integrity is prone to failure, causing gas leakage and forming a sustained casing pressure (SCP) at the wellhead. This work proposes a prediction model considering the real gas effect when evaluating SCP. The proposed model involves gas flow, leakage, and accumulation in the wellbore. With the pressure and temperature obtained by the flow equations as boundaries, the model estimates the gas flow rate at the leakage point and SCP. Subsequently, comparing the current leakage model with the conventional method demonstrates the model's performance. Finally, the current model is applied to an ultra-deep well to determine the leakage location by inversion. Further sensitivity studies reveal the influences of wellbore conditions on SCP, including the production rate, depth of liquid level, and annular fluid density. The study indicates that the traditional method based on ideal gas underestimates the mass flow rate by approximately 22% compared to the current model. When the adiabatic index of the conventional method is approximated as the isentropic coefficient, the mass flow rate may agree well with the current model. It is acceptable to predict the leakage flow rate by assuming that the production gas is pure methane and ignoring the influence of gas composition. The leakage position is the most influential factor for SCP. These results would help engineers predict SCP and determine the leakage location in wells.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 3","pages":"1425-1438"},"PeriodicalIF":3.5,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On account of the intricate geological conditions and the deficiency of a comprehensive set of exploration and development engineering technologies as well as supporting processes, the present development of deep tight sandstone oil and gas reservoirs remains in its nascent stage. Through the analysis and generalization of the horizontal well development technology for deep tight sandstone oil and gas reservoirs, a series of technologies have been established, encompassing reservoir geological evaluation and modeling, horizontal well development reservoir engineering validation, horizontal well geological design, and enhanced oil recovery processes. By taking the C 6 reservoir in Ordos basin, China as the research subject, in light of the research outcomes regarding the damage mechanisms and potential damage factors of tight sandstone oil and gas reservoirs, a geological evaluation approach based on the well log response characteristics was constructed, clarifying the porosity and permeability features of the C 6 reservoir, establishing the numerical model of the oil reservoir, and further elaborating the methods for dividing the development layers, selecting the development well pattern, and determining the development well density. The design parameters of horizontal well-segmented hydraulic fracturing were meticulously optimized, resulting in a minimum cluster spacing of 7 m and a maximum cluster spacing of 20 m. Given the influence of horizontal stress differences, the optimum fracturing density was ascertained to be 16 perforations per meter, and the optimal fracturing fluid volume was identified through simulation to range from 12 to 25 m³/m.

Both natural and synthetic antioxidants have proven effective in improving the oxidation stability of biodiesel, with numerous studies demonstrating their ability to extend the induction period and delay oxidative degradation. However, while the technical efficacy of these antioxidants is well-documented, the techno-economic analysis that evaluates the cost-effectiveness of using natural versus synthetic antioxidants remains unexplored. This creates uncertainty in selecting the most sustainable and economically viable antioxidant option. This study aimed to conduct a techno-economic analysis comparing the cost-effectiveness of synthetic and natural antioxidants in stabilizing biodiesel. The study evaluated synthetic antioxidants, specifically hydrogenated methoxy eugenol, and natural antioxidants derived from the methanolic extract of wild loquat plants, along with a comparison to commonly used synthetic antioxidants. Comprehensive simulations and modeling were conducted using Aspen Plus® V10 commercial simulation software in a block-wise manner. The technical performance was assessed by considering the quantities and qualities of biodiesel, glycerol, and antioxidants. The synthetic antioxidant processes resulted in negative net present values and longer payback periods of 11.7 to 17.8 years, while natural antioxidants showed shorter payback periods ranging from 3.8 to 12 years. Natural antioxidants, particularly those extracted from clove wastes and wild loquat plant parts, demonstrated superior techno-economic performance with the lowest operating and raw materials costs, shortest payback period, highest internal rate of return (IRR), and best profitability.
