针对现行井下作业工作量统计方法及其在塔里木油田应用中的局限性,提出了井下作业成本工作量这一概念,在此基础上,进一步引出了与成本工作量相关的几个概念,介绍了应用这一概念的基本思路与基本应用范围,旨在为类似井下作业的相关分析、预测提供参考,该方法也同样适用于天然气的开发。 In view of the current statistical method of downhole workload and its limitation in the application of Tarim oilfield, the concept of downhole operation cost is put forward. Based on this, several concepts related to cost workload are further introduced. The basic concept and basic application of this concept are intended to provide a reference for the related analysis and prediction of similar downhole operations. This method is also applicable to the development of natural gas.
