Research On Relationship Of Economic Reserves And Investment Cost In Liaohe Oil Field

- Economical recoverable reserves refer to the petroleum and natural gas cumulative production with economic value from underground in the border of the profit and loss curve. It can provide a scientific basis for companies in the exploration and development to evaluate the relation of recoverable reserves and the cost of the investment. Economical recoverable reserves are a dynamic amount with the technical, economic conditions national policies, the market, and management at that time.Economical recoverable reserves were calculated according to the economicl recoverable reserves and the cost of the investment relationship and the factors affecting the recoverable reserves.The factor influenced the economic recoverable reserves include technology and economical in Liaohe Oilfield.The technological factors include geological and development technical factors The way to hence the economic recoverable reserves of petroleum is to adjust the controllable man-made factors such as development mode,well net,well interval,technical measure,investment and cost.The method to forecast economic recoverable reserves has a strong adaptability in use.It needs ponder to validate the way though the actual production data among the eight methods to enhance the level of forecasts for economic recoverable reservesThe main method to Calculate the economic recoverable reserves include cash flow, economic limit, the time of economic exploitation of infill oil wells'economic output calculation method. The principles of the input-output balance must be complied to corresponding the threshold value of equilibrium for oil production and investment no matter which kind of methods were used. The different stages of development must be considered in calculating the economic recoverable reserves.Economic recoverable Reserves are 33482×104t, the remaining economic recoverable reserves are 12974×104t, the economic recovery is 14.5% in Liaohe oilfield at the present circumstances.It can help company to choose the better management to though the study of Economic recoverable reserves and it can also provide a basis for management plan.
