The Outer-Ring Oil Field Is Unlike The Boundary Exploiting Economy And Their Valuation Managing Lower Reservers Of Pattern

the outer-ring oil field as a result of has the small dispersible characteristic, cannot defer to the big oil field the mining way to develop, must aim at the different geology and the surface condition selects the relatively nimble method, large scale is reducing the cost and in the investment foundation carries on the development use. this article analyzed has studied all previous years reserves resources development use situation, has carried on the system analysis to the different time proven reserves characteristic, has clarified the reserves resources distribution, the constitution and its the oil deposit geology characteristic. According to the and loss balance analysis, has established the output, the investment, the cost development economic limit model, through to the model study, had determined under the different oil price, the different development way development management pattern, through to the oil-field development investment and the operating cost constitution analysis, has separately determined the present different development management pattern, the different oil layer, in the different output situation economical effective development investment economic limit through the dissection typical sub-area, has analyzed the influence oil-field development economic efficiency primary factor: One is the oil field operating cost changes along with the oil well output change, the oil well output higher operating cost is lower; two is the sub-area scale bigger, the average single well ground investment is lower; three is the different management pattern its cost of operation is different, also the small company system and international connects rails high oil price, enhanced the cooperation profit space, the mining economic limit further reduced. Finally through the applied mathematics method through to the oil price, the output, the cost and the investment sensitive analysis, has carried on the economical risk appraisal to each kind of influence factor.through pools capital in recent years, the cooperation pattern exploration work, already mined the partial periphery "three to be low" the oil field, has formed set of quite mature management patterns. But the different system has the different investment and the composition of capital, the different system correspondence develops any type the oil field, should have the quite explicit economic limit standard. this article profits from has developed the sub-area the development material, in subdivides the oil deposit appraisal unit in the foundation, discipline method and so on application geology, oil deposit, extraction and economy, loses,according to the conventional collection with mention fish for the extraction,mining way, the analysis different management pattern and the effective mining boundary relations, causes themanagement pattern and the resources characteristic corresponds, provides the basis for the determination reasonable development pattern.
