Summary

High pressure jet technology is an efficient material cleaning, removal and cutting technology, by squeezing the liquid spurted out of a specific nozzle to form a jet with high energy. As a green processing technology, it is widely used in oil drilling, ship derusting and machinery manufacturing due to its low cost, environmental friendliness, good removal effect and little influence on substrate materials. In the past few decades, the research of high pressure jet mainly focused on the characteristics of jet and the removal mechanism of conventional materials. With the expansion of its application field, new substrate materials, complex working conditions and special requirements have posed new challenges, mainly in the following aspects: the damage mechanism of jet pressure, distance, scanning speed on the new substrate materials is not clear, so it is necessary to explore the influence of different process parameters on different substrates; the current technology cannot meet the demand of parts with complex shapes or high dimensional accuracy requirements, so intelligent adaptive processing control is needed; efficient oil and gas production requires the use of jet technologies which do not pollute the reservoir, such as supercritical carbon dioxide and liquid nitrogen jets.
The present special issue focuses on the up to date theoretical and application researches of high pressure jet. High quality numerical, experimental, review and analytical researches are invited to be submitted to this issue. The most interesting subjects-but are not limited to- for this special issues are as follows:
Material damage mechanism under the action of high pressure jet and optimization of jet parameters
• Abrasive jet rock-breaking technology and its application
• Heat-fluid-solid coupling mechanism of supercritical carbon dioxide jet in rock-breaking
• Liquid nitrogen jet rock-breaking technology and its application
• New single and compound jet methods and their applications
• Development of super high pressure and large displacement pump
• Intelligent jet cleaning and cutting technologies

    Abstract Water jet technology is widely used in submerged buried pipes as a non-traditional trenching process, often involving a complex sediment response. An important adjustable and influential engineering variable in this technology is represented by the impinging distance. In this study, the FLOW-3D software was used to simulate the jet scouring of sand beds in a submerged environment. In particular, four sets of experimental conditions were considered to discern the relationship between the maximum scour depth and mass and the impinging distance. As shown by the results, a critical impinging distance exists by which the static scour depth can be maximized;… More >

    Abstract The actuator is a key component of the creaming tool in drilling applications. Its jet performances determine the effective reaming efficiency. In this work, a new selective reaming tool is proposed and the RNG k-ε turbulence model is used to calculate its internal and external flow fields. In particular, special attention is paid to the design of the flushing nozzle. The results show that the jet originating from the flushing nozzle has a significant influence on rock cutting and blade cooling effects. In turn, the jet performances depend on geometric structure of the creaming actuator. In this framework, a conical-cylindrical… More >

    Abstract The optimization of methods for the quantitative evaluation of risks in drilling engineering is an effective means to ensure safety in situations where high temperature and high pressure blocks are considered. In such a context, this study analyzes the complexity of the drilled wells in such blocks. It is shown that phenomena such as well kick, loss, circulation, and sticking, are related to the imbalance of wellbore pressure. A method for risk quantitative evaluation is proposed accordingly. The method is used to evaluate the risk for 9 drilled wells. By comparing the predictions of the method with actual historical data… More >
