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.

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.

With the continuous advancement of exploration and development technology, the complex geological conditions of natural gas resources are gradually being revealed. This article introduces the current situation of natural gas exploration and development, analyzes the important role of geological technology in natural gas exploration and development, and finally explores the de...
