Research On The Optimized Deployment Between Output And Cost Of Oil Plant And The Support Software For It

The traditional method of assigning production lacks organic synthesis of the output and the cost. When the oil plant implements the plan, it has to make the large scale adjustment in the assigning production plan in the later period, even unable to achieve the production target at the end of the year, and causes huge economic losses. In order to enhance the stability of production plan and the economic efficiency, this paper proposes the route:"collecting the primitive data of wells -> the forecast of wells'output and cost -> forms the budget plan ->sifting wells to form the Initial plan -> forms the revision plan -> forms the final plan". It helps to realize the optimization deployment between output and cost. The paper includes several parts below:The first part analyzes the characteristic of oil output and the constitution of operating cost, and introduces the forecast model of productivity and operating cost. It makes use of the model of GM (1, 1) to forecast the well's productivity and relative variable cost.The second part proposes the basic principle and the flow of optimization deployment between output and cost. First, on the base of the analysis of history cost data, it divides the operating cost into the relative variable cost and the relative fixed cost. All wells are arranged in the order of the unit variable cost from low to high. The well whose unit variable cost is smaller than or equals the threshold of unit variable cost and the new well whose unit variable cost is high go into production. Then, according to the principle of distribution, the total fixed cost is distributed to the wells that go into production, which forms the Initial plan. Second, to establish the revision plan, the decision-maker analyzes the statistical information of the Initial plan, and corrects the cost according to the past actual cost data. Finally, in...
