Oil Exploration and Drilling Technology

Importance of Oil Exploration

Oil is among the most important energy sources for the world economy, serving as a raw material for the manufacture of plastics, synthetic fibers, fertilizers, and other chemical products. It drives global economic growth due to its wide applications in various areas. With the continuous development of the global economy, the human population grows rapidly, and energy demand increases. Industrialization and urbanization add further pressures to the demand for oil and its derivatives, particularly in power, transportation, and manufacturing sectors. Despite limited and unevenly distributed oil resources, the search for new reserves remains crucial for long-term energy strategy and supply security.

Effective and correct oil exploration helps balance the supply with its growing demand, reducing over-reliance on known oil fields.


Position of Petroleum Resources in Global Energy Structure

Oil is the leading global power source and a significant factor in international economics and politics. It influences energy markets and international relations, affecting national security and economic development. Oil's high energy density makes it easy for storage and transport, maintaining its importance in sectors such as transportation and chemical manufacturing. Despite the growth of renewable energy sources like solar and wind power, oil continues to hold a substantial market share.

Role of Exploration in the Oil Industry Chain

Exploration activities are critical upstream activities in the oil industry. They provide a basis for subsequent development, production, and processing. Technological advancements in seismic exploration, deep-water drilling, and unconventional hydrocarbon resource exploration have improved development efficiency and economic viability, reducing drilling failures, exploration costs, and promoting positive oil resource development strategies.

Historical Development of Oil Exploration

Early Exploration Activities and Methods

The discovery and use of oil initially relied on surface seepages and other natural leakage phenomena. Ancient civilizations like Rome, China, and the Middle East utilized these seepages. The industrial revolution and increased energy needs led to more scientific methods, transforming oil exploration into a more systematized and scientific activity with the advent of drilling technology in the late 19th century.


Evolution of Seismic Exploration Technology

Seismic exploration technology, used since the 1920s, analyzes the reflection of seismic waves by underground rock layers to infer structures and oil reserves. The technology has evolved from two-dimensional to modern three-dimensional and four-dimensional seismic exploration, improving precision and providing a comprehensive geological picture. Advances include the transition from single longitudinal wave methods to joint longitudinal and transverse wave methods.

Innovation and Future in Oil Exploration

High-Performance Drill Bits and Smart Drilling Technology

High-performance requirements for efficient oil exploration involve reducing drilling time and cost, achieving high efficiency and stability under complex geological conditions, and utilizing high-performance drill bits. Smart drilling technology uses automation, real-time monitoring, and data analysis to ensure precise and efficient drilling operations. Technologies include automated drilling systems, remote monitoring, and real-time data transmission.


Integrated Data and Geological Modeling
