Oil and gas field development engineering is a subject that uses modern comprehensive science and technology to understand and develop oil and gas reservoirs. It is not only a methodology, but also a discipline to guide the decision-making of oilfield development. Its basic content is to study the effective oil displacement mechanism and driving mode, predict the future performance, and put forward methods and technologies to improve the development effect on the basis of establishing geological models and reservoir engineering models based on reservoir description, so as to achieve the purpose of enhancing oil recovery. It can be summarized as follows: (1) Early evaluation and development feasibility study of oil and gas fields can design several development tests (also called pilot tests) to provide basis for comprehensive development of oil and gas fields; (2) Oil and gas field development design and comprehensive development mainly include oil and gas reservoir description, selection of reasonable production mode, reasonable division of development layers, well pattern deployment, determination of reasonable development speed and production level of oil and gas fields, determination of various development schemes through numerical simulation of oil and gas reservoirs, determination of drilling and production technology and logging technology of oil and gas fields, comprehensive analysis and comparison of economic and technical indicators combined with ground facilities, selection of the best development scheme, formulation of detailed rules for implementation of the scheme, etc. ③ Partial or comprehensive adjustment of the scheme, etc.

Oilfield development engineering is a knowledge-intensive, technology-intensive and capital-intensive industry, and it is a huge project with multi-disciplinary comprehensive application. Mainly involved in geology, geophysical exploration, drilling, oil production, oil storage, storage and transportation, economy, management, hydropower, civil engineering and other departments.
