Additive manufacturing (AM) has evolved from a rapid prototyping technology into an advanced design and manufacturing approach that enables new possibilities in engineering product development. Unlike conventional manufacturing methods, AM provides unprecedented design freedom by allowing the fabrication of complex geometries, lightweight structures, customized products, ... Read more.

The Sichuan Basin contains multiple hydrocarbon-bearing formations, and oil and gas development in the basin is challenged by complex subsurface conditions, including highly variable formation lithologies, diverse reservoir fluids, and irregular formation-pressure systems. During drilling operations, influxes of acid gas commonly contaminate drilling fluids. Acid-gas conta... Read more.

Core analytical data, including petrographic and epoxy-impregnated thin sections and scanning electron microscopy (SEM), were used to investigate in detail the mechanisms of pore development in the Lower Shihezi–Shanxi tight sandstone reservoirs of the Sulige Gas Field. The results show that the reservoir sandstones contain abundant lithic fragments and mineralogica... Read more.

In recent years, the proportion of low-permeability, low-pressure, and low-productivity oil and gas wells in China’s oilfields has been increasing year by year. As a key production mode for such wells, intermittent production plays an important role in stabilizing production, reducing energy consumption, and protecting reservoirs. However, the traditional manual intermitte... Read more.

Well completion is the process of creating an effective flow path between the reservoir and the wellbore. An effective completion must maintain the mechanical integrity of the wellbore while ensuring fluid flow within the well. This paper outlines a method for optimizing horizontal well design, using a skin factor mod... Read more.

Ultra-deep well drilling in the Zhebachang Structure and Suining-Santai Qixia Formation Slope Structural Belt of northwestern Sichuan is confronted with a harsh environment characterized by high temperature, high pressure, and high stress. The geological conditions are complex, variable, and difficult to pred... Read more.

Ordinary World, set against the backdrop of a period of social transformation, deeply integrates traditional culture into its character construction. In rural society, hierarchical rules govern interpersonal relationships; mutual assistance among the Sun family and their neighbors highlights the characteristics of rural culture. Marital and romantic ethics reveal the profo... Read more.

Homology of medicine and food” embodies the Chinese nation’s unique wisdom, integrating nutritional and therapeutic functions to form a health philosophy centered on prevention, nourishment, and syndrome-based diet therapy. From the legend of Shennong to The Yellow Emperor’s Inner Canon, Sun Simiao’s Prescriptions , Li Shizhen’s Compendium, and modern scient... Read more.

Small leaks in pipeline systems, though less dramatic than major ruptures, pose significant long-term threats to safety, environmental health, and operational efficiency. Early detection is critical, and various online (real-time) detection techniques have been developed to address this challenge. This paper presents a comparative study of three major classes of online leak ... Read more.

The document explores the profound influence of ancient Chinese myths of Fuxi and Nuwa on Traditional Chinese Medicine (TCM), particularly in the context of mugwort culture and its applications. Fuxi and Nuwa, as the creators of humanity and protectors of mankind, are deeply connected with the origins and dev... Read more.
