Study On Internal Proration Optimization Mechanism Of Oilfield Enterprises Based On Single-well And Unit Accounting System

At present, Oilfield enterprises are facing pressures from the yield and cost, as a result, how tobalance the relationship between the production allocation and cost, and improve the Oilfieldenterprises’ efficiency have become one of its important problems. As the using of reservoiroperation management and meticulous management theory, oilfield enterprise designs thesingle-well and unit accounting system, and constructs the internal proration optimizationmechanisms, which is benefit for revealing the relationship between the yield structure and cost.Through exploring the measures to plan annual production scale and achieve effective productionallocation, provide sufficient support for the production of the oilfield enterprises operatingdecisions.After researching traditional production allocation mechanism and using reservoir operationmanagement theory, economic yield theory, and so on, this article re-combines its process, andputs the block as a key node to realize the convergence between the geological productionallocation and the economic production. Furthermore, after allocating oilfield enterprisesproduction tasks, carry out block geological proration meticulous management, and forecast theproduction structure of the old wells, new oils, and measures wells. After building the old wellsproduction-cost optimization model, calculates the scale of economic production and the cost ofold wells, which is a basis to realize the geological allocation. After building new wellsproduction-cost function and the measures wells’ production-cost optimization model, ensures thelowest cost on the basis of the remaining production. At the same time, this article chooses theDEA to ensure the smooth implementation of the method of production allocation scheme, inorder to realize the dynamic evaluation of the production allocation scheme and adjustaccordingly. For the implementation of the program of the annual production allocation, analysesthe deep relationship between the actual cost and the planned cost, which is an importantreference configuration as the guidance of annual production costs. Finally, carry out the oilfieldinternal proration optimization mechanism with a certain eastern oilfield enterprise, and putforward safeguards measure.
