A Study On Daniudi Gas Field Production And Management Decision-making Quantitative Analysis

With the technical progress and the economical development, the energy structure has changed gradually. Natural gas, of which consumption in the rapid growth, will become a first choice for energy in the future. Our country gas reserves are rich, the mining potential is huge, but most gas fields are in modest or small scales, uneven distribution, and low permeability reservoir in the main, gas buries deeply, the mining technological requirement is high, the water gas proportion is large, which require companies to ensure they obtain enough economic efficiency, promote scientific and rational development of the resource by the economic evaluation. Gas field development and production takes long time , invests in a big way and has high risk, which highlight the importance of scientific and correct decision-making. How to achieve cost-effective production, adopt what kind of effective measure of technology, economy and management and so on, reduce the production cost, and improve the whole economic benefits of gas field are the problems that need to be paid more attention and solved urgently.This article embarks from the influencing factors of economic benefits, uses the economic evaluation for reference and the dynamic break-even as modeling's method foundation, provides the data support from the quantification angle for the decision-maker. On the basis of the existing domestic and foreign research, this article unifies the actual exploration mining process of Daniudi gas field, systemly analyzes the investment structure and cost structure of Daniudi gas field, establishes the basic models of investment, cost, production, income and the related decision-making models, and applies the above models to operation decision-making of Daniudi. This article also carries on the classification to the single well economic benefit, innovatively discusses the changing analysis of the influencing factor on the basis of the datum balanced analysis, and aims at the characteristic of high risk to give reasonable analysis.This article analyzes and solves the problem by economical judgment, has provided a scientific method and the new mentality for the development and management of low-permeability gas field. Its research results not only have an important theory value and practical significance to Daniudi gas field, but also provide broad giudance for natural gas companies to reduce cost, implement modern management and the level of operation decision-making.
