By analyzing the advantages and disadvantages of these flowmeters, their range of application can be concluded, which has offered us a good reference as to which type of flowmeter is most properly to be used in a given circumstance logging job.

文章介绍了SRCT6701钻进式井壁取心器的工作原理,针对现场施工中出现的液压控制部分和机械传动部分的问题进行了分析,提出了处理办法.

At present, most oilfields have entered into middle-late development stage; annual production logging operations are rising gradually. In order to solve the three problems of the existing production logging instruments-too long combination, low precision and easy fault problem, CNPC Logging developed a new generation of production logging combination tool. A new generation production-HSR integrated production logging tool was developed. It owns two patents, three prominent characteristics including high reliability, high precision, and smaller length. Some main technical indexes such as logging range and precision, integration of logging data, and repeatability have been in the leading level in China. Good application results have been achieved in logging test and logging service process. It is proved that the integrated tool could completely meet production well logging engineering demand in domestic oilfields, and has broad application prospect.

<正>随着全球经济一体化的发展和我国石油企业建设综合性国际能源公司的奋斗目标的提出,为保障国家能源安全、获取和掌控更多的海外油气资源,适应资源国要求实现我国石油企业国际业务规模、有效、可持续发展。近年来石油企业对合作人才的需求呈

随着油气田产量递减加快,勘探开发难度加大,生产要素价格上涨,油田企业面临巨大的成本控制压力。长庆油田在多年探索的基础上,探索建立并推广实施了"基于作业的标准成本管理"方法。该方法将作业成本管理概念融入标准成本系统,确定每个作业过程、每项要素的成本支出标准,为预算编制、成本控制、正确评价作业中心及相关责任成本中心的业绩提供了依据。推动基于作业的标准成本管理工作,必须有强有力的组织基础、信息化手段和运行机制的保障,做到全员参与,协同执行。通过推广实施标准成本管理,长庆油田优化了生产运行,降低了成本费用,提高了企业的预算水平和管理效能。
