Abstract: The Fuyu reservoir in Xinmin area is a delta plane-front facies deposit, and the channel sand body in this area is the main reservoir of oil and gas. Due to the complex sedimentary environment, the sand body shows great variation in thickness and distribution. In this study, the method of combining well vibration, model forward modeling and stratum slicing are used to predict the sandstone bodies of different thickness successfully. Especially for the thin sand body with a thickness of less than 5 meters, this study found that the GR curve can effectively distinguish sandstone and mudstone through the intersection analysis of logging curves, and applied the GR curve co-simulation inversion technology to perform fine characterization. In addition, the study also reveals that the northeastward twisting fault zone in Xinmin area is a favorable accumulation area of the reservoir, which provides a new direction for oil and gas exploration. This study not only improves the accuracy of sandstone prediction, but also provides a valuable reference for oil and gas exploration under similar complex geological conditions.

Abstract: Original sentence: "Erosion corrosion is a significant factor contributing to the thinning and failure of oil pipelines. This paper addresses the issue of erosion corrosion of oil pipelines in oil fields under the action of multiphase flow, the main factors affecting the erosion corrosion are introduced, including the hydrodynamic factors, solid particle properties, fluid medium properties and temperature, It summarizes and analyzes the mechanisms through which these different factors affect the erosion corrosion of oil pipelines. The paper points out that increased fluid velocity in oil pipelines, sudden changes in flow patterns, and turbulent kinetic energy can accelerate erosion corrosion to some extent, With the increase of flow rate, erosion corrosion mechanism will change from electrochemical corrosion dominant to erosion accelerated corrosion, There is a maximum value for erosion corrosion based on the solid particle impact angle. The harder and sharper the solid particles are, the stronger their impact on the pipeline, especially the impact of low Angle impact is more significant; however, the diameter and quantity of particles can affect the development of erosion corrosion due to 'particle size effect' and 'shielding effect.' Additionally, lower pH values and higher temperatures of the fluid medium will increase pipeline erosion corrosion. Finally, future research directions for studying erosion corrosion in oilfield pipelines under multiphase flow conditions are discussed in light of existing research."

Abstract: In the production process of oil and gas fields, for old wells, sealed wells, etc., if the bridge plug or packer is inserted into the well for a long time, the sealing cylinder will harden under the high-temperature and high-pressure environment of the wellbore. The sealing cylinder cannot contract normally and tightly adhere to the inner wall of the casing. During the tool unsealing and lifting process, impurities such as scale and rust on the casing wall will be scraped off and continuously accumulated, ultimately causing the bridge plug or packer to jam and unable to successfully complete the tool unsealing and salvage. During construction, the method of repeatedly moving the pipe column and suspending it is usually used for unblocking, and nitrogen gas lifting and lowering liquid construction is added, but the results are not ideal. During the process of moving the tubing, fatigue damage to the tubing increases the risk of well control and complex wellbore conditions, while significantly prolonging the construction period and increasing construction costs. Therefore, it is urgent to develop a degradation and ablation agent for hardened rubber parts, which can degrade and soften the hardened rubber cylinder, ensuring the smooth operation of tool salvage. Rubber products obtained through normal cross-linking reactions exhibit a regular grid like molecular structure, which can resist the invasion of organic molecules and oxidant molecules. This is also the reason why rubber products are resistant to organic solvents and acid-base corrosion. The experiment proposes to use a combination of "dissolution" and "destruction" methods to soften and melt the excessively cross-linked and hardened rubber cylinder.

Abstract: The shield tunneling method is the main construction method in subway tunnel construction, which has the characteristics of safety, efficiency, mechanization, and high degree of automation. However, the shield tunneling equipment is huge, the supporting facilities are numerous, and the site requirements are high. In response to the problems of slow slag removal speed and low construction efficiency in shield tunneling under the construction conditions of small wellhead shield tunneling sections in urban subways, taking the shield tunneling section of Guangzhou Metro Line 13 Phase II as the background,This article introduces the main components, working principles, installation and transportation processes, fault handling, and benefit analysis of the continuous belt conveyor slag removal system,This article elaborates on the method of using a continuous belt conveyor in the tunnel combined with a vertical lifting system at the wellhead to achieve continuous slag removal during underground shield tunneling construction in a narrow wellhead construction site. This not only improves excavation efficiency but also reduces construction costs, solves construction problems, and provides reference for similar projects in the future.

Abstract: Landmark building is the external image and social card of a city, which reflects the traditional culture and spiritual connotation of a city and even a country. Landmark buildings not only refer to the large modern buildings in the city, but also include large sculptures, artworks, historical relics and so on. The innovative and creative industries of landmark buildings and urban images are often attached to the cultural tourism industry. At present, the development and research in this field are vague in definition, and the industrial development situation varies significantly in different cities and regions. Domestic first-tier cities such as Beijing, Shanghai and some tourist cities such as Hangzhou and Suzhou have advanced and comprehensive development in this field, and there are also unconscious spontaneous behaviors of the public to broaden the research content in this field. In contrast, some cities have not yet formed a good industry in this field. The development of innovative and creative industries for landmark buildings in foreign countries is earlier than that in China, and its forms are more abundant and avant-garde, which is worth learning and reference for researchers. The development of innovative and creative industries in landmark buildings will enhance the image and popularity of the city, thus boosting the development of the local tourism economy. At the same time, the industry shows the meaning and connotation of landmark buildings by means of artistic expression. In addition, innovative and creative products will also promote the popularization of arts education for all. Through a series of research and practice, the author also adds some specific cases and feasible research routes for the research and development of this field.
