It is very difficult to deal with such accidents,\u0000 and the drill pipe in the borehole has to be discarded in serious cases. Therefore, the stability of the borehole wall seriously affects the drilling quality and efficiency. At present, there are three effective methods of ensuring wellbore stability: casing, drilling fluid, and agent plugging\u0000 technology. Casing can effectively prevent instability of all types of unstable formations and can isolate different pressure zones. Using the proper drilling fluid can control drilling fluid loss, reduce free water infiltration into the borehole wall, and form a thin and dense mud skin, which\u0000 is conducive to the stability of the borehole wall. Agent plugging technology, especially chemical gels, is mainly aimed at the broken zone. After entering the formation, it makes the entire broken zone form a single high strength unit, improves the cementation ability of the lost formation,\u0000 and improves the sealing and bearing capacity in order to achieve the purpose of sealing and plugging of leaks. In this paper, the present situation, technical principles, and technological processes of wall protection technology in ocean scientific drilling are summarized, and the different\u0000 types of wall protection technology were researched and tested. The results of this study provide a reference for international ocean scientific drilling in the future.","PeriodicalId":49878,"journal":{"name":"Marine Technology Society Journal","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41475951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efficient Terrain-Aided Navigation System with Submap-Size Calculation and Embedded System 基于子地图尺寸计算和嵌入式系统的高效地形辅助导航系统

TAN can locate a vehicle by calculating the similarity between an a priori map and a vehicle's real-time observation consisting\u0000 of a set of bathymetric measurement points. However, the amount of measurement points in the real-time observation affects both positioning accuracy and computational consumption of the TAN system, making it challenging to calculate a suitable size of real-time observation in TAN. With a smooth\u0000 seabed terrain, a small observation area leads to insufficient topographic features and finally an inaccurate matching result, while a large area with a mount of features results in high computational cost. This paper proposes a method to restrain the size of observation in TAN systems based\u0000 on terrain entropy and difference of normals. Meanwhile, this paper implements the TAN algorithm into an embedded system architecture used by actual underwater vehicles that are already in service to reduce the power consumption of the TAN system. The effectiveness of the algorithm has been\u0000 demonstrated through playback experiments based on a semi-physical simulation platform using a PC/104-embedded computer.","PeriodicalId":49878,"journal":{"name":"Marine Technology Society Journal","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46519454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
