Drilling instrument application technology development ideas

In order to allow the grassroots team and management to truly feel the benefits of instrumentation, China has proposed a project to promote the application of drilling instruments, digital wellsite construction, and applied research on field drilling instrument data integration.

  Some foreign companies have long used computer network technology and satellite communication technology to establish a drilling data center. Through remote data transmission, dynamic data such as engineering, geology and drilling fluid in the well site are transmitted back to the base in real time, realizing the connection between the drilling site and the base. Two-way contact and data sharing. For example, companies in the United States and Italy have successively established drilling analysis and command centers based on computer network systems and satellite communication technologies, making full use of real-time data resources on site to ensure the smooth operation of drilling operations in remote, offshore and environmentally harsh areas. An automated large database was built.

  In recent years, Tarim, Tuha, Zhongyuan, Shengli, Dagang and other oil fields in Xinjiang have carried out research and experiments on data remote transmission.

  In terms of promotion and application, Shengli Oilfield is at the forefront, and technical and management personnel can access on-site data information at the rear base.

  Daqing Oilfield also used satellite communications in the Hailar area in the late 1990s to periodically send some information back to the rear. In recent years, Daqing drilling system has also carried out data remote transmission test and application in Xujiaweizi and Yingtai and other areas, but it has not formed an application scale.

  The so-called digital wellsite, that is, on the site of drilling (first from the key exploration well), establish a wireless local area network, intercept the signal from the logging instrument in real time or separate the signal from the instrument of the drilling equipment to read the data collected during the drilling process, and establish A small database of wellsites that uses this database to provide an integrated data monitoring platform for the well team (the grassroots team benefits). Utilize the existing mature communication technology, the data in the small database of the well site will be transmitted back to the rear drilling data center in real time, laying the foundation for further utilization of the data.

  Build a simple website at the rear. The website is based on a database system. The data source comes from the data transmitted from multiple drilling sites. After simple processing, the drilling production site data consultation and browsing interface can be provided for authorized production managers.

  Under the premise of communication technology, on-site network camera and video real-time remote transmission technology application research can be carried out, video surveillance can be realized at the rear, which is convenient for guiding on-site work (providing convenience for management).

  In this way, both the grassroots team and the management layer can truly feel the benefits of instrumentation, and will further promote the development of drilling instrument application technology.
