摘要
桶油成本是衡量石油公司成本竞争力的重要指标.低油价下更是如此。完全桶油成本中较为可控的是桶油五项成本,其最主要构成为桶油折旧、折耗及摊销(简称桶油DD&A),占桶油五项成本的55%左右,因此石油公司控制住桶油DD&A基本就控制住了桶油成本的变化趋势。通过当期和次期桶油DD&A计算公式推导,首次提出桶油DD&A变动公式,并应用于某虚拟自营油气田。通过石油公司滚动预算和上市储量季度评估结果,可得知其当年预期产量、储量、公共设施及钻完井投资的情况,再结合下年度预算编制过程中下年度工作量、开发和资本化投资规模情况,使用桶油DD&A变动公式,通过Excel可以得出在不同工作量以及对应的产量规模、投资费用情景下使油气田次期桶油DD&A维持当期水平的最低储量增长值,明确降低桶油DD&A的努力方向,促使经济和油藏工程师共同协作、优化组合,让上市储量评估与生产运营紧密地联系起来,从而达到维持并降低桶油成本的目的。
The cost for a barrel of oil at low oil price.Five-cost for a barrel is an important index of cost competition of oil companies ,especially of oil may be controlled in the complete cost for a barrel of oil, which consists of depreciation,degradation and amortization for a barrel of oil mainly (DD&A for a barrel of oil for short) , accounted for about 55%.So the control on the DD&A for a barrel of oil for the oil companies equals to the control on trend of the cost for a barrel of oil.After the DD&A formula in the current period and next period was deduced,DD&A variation formula for a barrel of oil was proposed first and applied to certain virtual self-operated oil and gas field.Expected production,reserves,public facilities and investment for well completion and drilling in those years may be known according to the roiling budget and quarterly as- sessment results of the SEC reserves for oil companies.Combined with work load,scale of development and capital investment during budgeting for next year,the minimum reserve increment for the DD&A for a barrel of oil remains for the next period as the current period may be obtained through Excel and DD&A variation formula for a barrel of oil at the conditions of various work load,corresponding production scale and invest- ment cost.The direction of reducing DD&A for a barrel of oil was clear.It promotes the co-operation and optimization of economic and reservoir engineers,and makes the SEC reserves assessment and operation be connected closely ,which will achieve the goal of maintaining and reducing the cost for a barrel of oil.
