摘要
以发现美国各类钻井总成本长期、中期、短期的变化规律为研究目的,采用美国石油协会(API)的数据报告对美国钻井成本进行分析,研究发现:1)研究期内,美国钻井总成本变化经历了3个阶段:1990年以前先增后减,1990—1997年平稳不变,1998—2008年快速上涨;2)各类钻井成本基本都经历了上述变化过程;3)油井钻井成本的变化比气井、干井更为稳定,而气井相反,其变化波动性最大;4)跟陆上井相比,海上钻井成本的波动性更大,可预测性更弱。
This paper aims to find the variation rules of overall cost of America＇s all kinds of drilling in a short-, middle- and long-term by using API data. The overall drilling costs underwent three stages, rising and then falling before 1990, steady during 1990--1997, and a fast rising during 1998--2008. Oil wells costs are steadier than gas wells and dry wells, gas wells fluctuated most. Compared with land wells, oceanic wells costs have a big fluctuation with a poor predictability.
