【摘要】：抽油机示功图数据的存储是油田信息化重点关注的问题之一。若将抽油机示功图存储在实时数据库中,每口井每幅需要投入500个数据点进行存储,成本高昂;传统的抽油机示功图存储方法是将示功图数据存储在关系数据库中,此方法读取效率不高,不便于进行实时数据分析,且需要在油田生产作业区及作业区以上组织机构部署关系数据库服务器,代价依然昂贵。生产物联网示功图数据压缩方法,经过超过2×104幅示功图数据的计算、分析和验证,可以通过数据处理、精度确认、求取差值和数据存储4步计算将抽油机示功图数据有效压缩至原数据大小的1/250,直接存储于实时数据库中,实现了降本增效的目的。该方法经过中国石油天然气集团公司相关油气田公司的试用,验证了其实用性,节约了投资成本。
[Abstract]:The storage of the indicator diagram data of the pumping unit is one of the key problems in the oilfield informatization. If the indicator diagram of the pumping unit is stored in the real-time database, 500 data points are put into storage in each well, and the cost is high. The traditional method of storing the dynamometer diagram of the pumping unit is to store the indicator diagram data in the relational database, and this method is read. The efficiency is not high, it is not easy to carry out real-time data analysis, and it is necessary to deploy the relational database server in the oil field production area and the operation area. The cost is still expensive. The method of data compression of the indicator diagram of the production network, through the calculation, analysis and verification of more than 2 x 104 indicator diagram data, can be processed through data processing and precision. It is confirmed that the 4 steps of the difference value and data storage are calculated to effectively compress the indicator diagram data of the pumping unit to 1/250 of the original data size, and directly stored in the real time database to achieve the purpose of reducing the cost and increasing the efficiency. The method has proved its practicality and economize the investment cost through the trial of the related oil and gas field company of China Petroleum and Natural Gas Group Corporation.
