Study On Petroleum Operation Cost And Control System In Erlian Oilfield

The paper introduces the status of development and oil-gas cost management in Erlian Oilfield, theories of operational research and modern economics are utilized to set up a scientific control system of oil-gas cost management, level of oil-gas operating cost management is improved and operating cost is reduced, thus profit of oilfield development is maximized.Details of this article are described as follows:1.ABC-method is utilized to ascertain the key objects of oil-gas operating cost control projects.2.DEA-theory is utilized to evaluate the validity of operating cost control projects and ascertain operating target cost of relatively effective years in oil-gas sections.3. Method of cost critical point analysis is used to control cost of different oil-gas sections and management units.4. Economic monitoring and early-warning theory is utilized to study oil-gas operating cost monitoring and prediction system.Theories and methods are coherently used in the production practice of the oilfield and a system of oil-gas cost control and monitoring and prediction method have been set up. The system is widely used in the production of Erlian Oilfield and operating cost is controlled effectively and a remarkable economic benefits is obtained.
