| 摘 要： | 技术学习是实现页岩气开发技术工程化的重要途径,开发技术工程化是实现规模化商业开发的前提。页岩气开发极大地区别于常规油气,具有显著的技术学习效应。依据涪陵页岩气田实地调研数据,拟合不同开发阶段对应井别的钻井总成本学习曲线,并与传统的技术学习曲线进行了对比分析。研究发现,开发早期相对中后期,技术学习速率更高,钻井成本变动更剧烈;考虑规模效应时,钻井成本变动较为平缓,但技术学习的间接作用则更为明显。

The learning curve research on technology engineering implementation for Shale gas development in China |

| Abstract: | Technological learning is the important road to realize shale gas development technology engineering,and tech-nology engineering is the premise to realize large -scale commercial development.There are many differences in technology learning effect between conventional and unconventional oil and gas resources.Technology learning curve traditionally de-scribes the relationship between marginal cost and the quantity of well drilled,which can not reflect changes in drilling costs caused by uncertainties coming from factors such as geology condition,technology and environment.Based on realization of technology engineering,the present paper identifies the effect approach of technology learning to drilling cost by two ways:direct technology scale effect and indirect effect caused by reducing possibility of uncertainties,rising success rate of well -drilling,and reducing sunk cost of well -drilling as well as mechanism and evolution process.Through so -site survey and expert interviews,this paper describes total cost learning curve corresponding to different functional wells.Compared with traditional technology learning curve,we find that at the early stage of shale gas development,there is a high technology learning rate with drilling cost fluctuation.When only taking scale effect of technology learning into account,there are little changes in drilling cost,and indirect effect of technology learning on drilling cost increases technology learning effect dra-matically. |
