摘要: 中国页岩气大规模开发处于起步阶段,钻井计价方法不够科学是一个比较突出的钻井投资优化管理问题。 研究提出一套“计价方法一体化+ 标准井管理”的钻井投资优化分析方法。计价方法一体化就是建立满足油气勘探 开发项目建设全过程管理需要的钻井工程计价方法体系,前提是需要建立统一规范的钻井工程工程量清单计算规则、 钻井工程造价项目构成、钻井工程全过程计价标准体系。标准井管理是建立若干个标准井工程,用于科学投资决策和 钻井生产组织,主要表现为6 种作用。上述方法用于中国石油2021—2030 年页岩气发展专项规划的开发井投资测算 和降本增效优化分析,介绍了钻井生产力水平分析和预算定额、概算定额、概算指标、估算指标、参考指标的编制以 及钻井投资测算方法和结果。

Abstract: Large-scale development of shale gas in China is at the initial stage. Unscientific valuation methods present a major challenge to the optimization management of drilling investment. This paper proposes a set of optimization analysis methods for drilling investment: "valuation method integration + standard well management". The purpose of valuation method integration is to establish a valuation method system for drilling engineering which will meet the needs of the entire process of management of oil and gas exploration and development projects. The premise is to establish unified and standardized calculation rules for the bills of quantities for drilling engineering, cost composition of drilling engineering projects, and a standard valuation system for the whole process of drilling engineering. The standard well management process is to establish several standard well projects for scientific investment decision-making and organization of drilling operation. These methods were applied in the calculation of development well investment and the optimization analysis of cost reducing and benefit increasing in CNPC's special planning for shale gas development in 2021-2030. This paper introduces the analysis of drilling productivity levels and preparation of budget quotas. There are 6 main functions: rough calculation quotas; rough calculation indicators; estimation indicators; reference indicators, and the methods and results of drilling investment calculations.

Key words: shale gas, drilling, investment, integration, standard well, bill of quantities, valuation method, valuation standard, cost reducing and benefit increasing, planning
