Study For Development And Management Pattern Of Daqing Periphery Marginal Oilfield

The petroleum is one of the most important energy in the world. With the high speed development of the world economics, energy is consumed largely, countries all over the world attaches great importance to the exploration and exploitation of oil. Oil reserves on Land is limited .Most of the oil has entered the high watery later period and the output is low, most has entered the ranks of the marginal oil fields. Marginal Oilfield is also called the "three lows" oilfield, that is, low productivity, low permeability, low pressure, which generally refers to the large area, and individual well productivity and profit is low.Managing marginal oilfield scientifically and effectively not only can improve the economic benefits of the marginal oilfield, but also can play a role to alleviate the increasingly tense oil resources.Daqing marginal oilfield is mainly distributed in the Daqing periphery. Through several year optimal development, at present the oil has already used about 1/3, but also 2/3 petroleum reserves has not used yet. Even if the oil reserves have been used, the development effectiveness and economic efficiency is not very satisfactory, so how to manage the marginal oilfields effectively has become increasingly concerned issue the of oil.The paper takes Daqing periphery marginal oilfield as the background, and establishes development and management pattern, which provides some suggestions for marginal oilfield's effective development and the scientific management. First, the paper analyses and summarizes the current research in the marginal oilfields'development and management. Second, from research the correlative theory of marginal oilfield and management, we have a certain understanding on the marginal oilfield's development pattern and the management pattern which provides a written reference. Third, the paper establishes a marginal oilfield development and management pattern, which is divided into three parts: technical aspect, economic aspect and management aspect. technical aspect, the article proposes development technology which suits the marginal oilfield; the economic aspect is the core of this article ,which stated mainly from the uncertainty analysis, development and investment analysis ect. to analysis the marginal oilfields. Finally the paper aims at the characteristic of the marginal oilfield which proposes the concrete development and management measure. And also the paper takes Daqing periphery oil field for example to analysis. Forth, summarizing the paper, point out the deficiency and prospecting the future trend of marginal oilfield.
