Petroleum and natural gas engineering is a project that uses scientific theories, methods, technologies and equipment to efficiently drill underground oil and gas resources, maximize and cost-effectively extract oil and gas from the formation to the surface, and safely separate, measure and transport oil and gas technical field.

Petroleum and natural gas engineering involves basic and applied disciplines such as engineering mechanics, fluid mechanics, oil and gas geology, seepage physics, automatic control theory, computer technology, etc. The engineering problems to be solved include drilling, completion, testing, reservoir development geology, oil and gas seepage laws, Engineering issues such as oil and gas field development plans and mining technologies, enhanced oil recovery, collection and processing of oil and gas fields, long-distance transportation, storage, and networked transmission and distribution. This engineering field is related to disciplines such as mineral census and exploration, earth exploration and information technology, mining engineering, engineering mechanics, chemical engineering, mechanical engineering, and transportation engineering.
