The reservoir management is a process in which people use sesmic exploration, drilling, geology, logging, testing, production downhole operation, surface construction and dynamic supervision ect. in the life of the oil/ gas field exploration and development to obtain the optimal economic recovery factor.The reservoir management has experienced three stages. First stage is the non-intensive management system in which each person did thing in his own way. Second stage is the multiple disciplineswhich combined geology, geophysics with reservoir simulation, from 1970 to 1990. Third stage begins with the inviting modern management system being used in production, which is the result of combining geophysics, reservoir geology, reservoir engineering, drilling and well completion, surface construction engineering, economic analysis, management and computer science.Many new subject, such as the cybernetics and the system engineering, has been established from World War II. Firs book " The Cybernetics" has been published by Vena in the 1940 s. The cybernetics is the result of combining with the multiple disciplines, which are automatic control, electronics technique, radio communication, neurophysiology, psychology, medical science, mathematics logic, calculation technique, statistics mechanics with other subject.The development of the cybernetics has involved four stages. In first stage, the classical cybernetics was established, which mainly researchs single import ,single export and linear constant state system. In second stage, many new cybernetics were researched, such as the engineering cybernetics, the nerve cybernetics, the biology cybernetics, the economic cybernetics, and the society cybernetics etc. In third stage, the modern cybernetics has been established, which mainly researchs multiple import, multiple export, time-variant and discrete system. In fourth stage, automatic cybernetics has been researched.There are two important jobs should be firstly done in oil and gas field development. The first one is how to fufill a good management of the field. The second one is how to control the oil and gas production performance. In fact, these two points have foretold a birth of a new subject which we can call it reservoir management control engineering.Taking the XINCFIANG gas field as an example, This paper has systematically researched reservoir management, reservoir characterization, reservoir modeling, production controlling models, production performance controlling, development scheme optimazing and economic evaluation. There are four major progresses being obtained in this research as below:(1) A resultful management and control system has been promoted, on the base of multiple discipline team work,which combines sesmic exploration, drilling, geology, logging, testing, production downhole operation, surface construction and dynamic supervision ect. in the life of the oil/ gas field exploration and development to obtain the optimal economic recovery factor.(2) Four type curves of early-stage development scheming have been established for the first time, which are Qctm/ No vs ER type curves, QctR/ No vs ER type curves, QmaxtR/ No vs ER type curves, Qc/ Qmax vs ER type curves. 96 earlier period development schemes of the XinChang JP1 gas reservoir, JP2 gas reservoir and JS gas reservoir have been put forwad by using the four type curves.(3) The principles and methods of how to control the reservoir production performance have been put forward comprehensively and systematically for the first time. The production data of 3 gas fields, 10 gas reservoirs and 333 wells have been matched with 15 controlling models. The Weibull model is the best, then the WengCylce model and the Arps model are better, in matchingdata of the gas field or reservoir. But the Fwgl model is the best, then the Arps model are better, in matching data of the single gas well.(4)The principles of development scheme adjustment between horizons, blocks and wells in the densed sandstone gas field have been put forwar...
