PetroChina Logging Self-Developed Array Flow Imaging Log Instrument
On April 18, the news came from the Chinese oil logging that the company's self-developed array mobile imaging log instrument was successfully applied for the first time in Tuha oilfield. After 14 hours of construction of the log meter, in the production section test of maxin 56-140H horizontal well, the logging test of 850 m horizontal measurement section was completed once, and the high quality data was obtained.
Ararray flow imaging log is mainly used for dynamic monitoring of large and horizontal wells. The logging instrument string is composed of the array electromagnetic wave water holding rate, array temperature difference and array eddy current flow meter. Through the "one string measurement", the instrument can be measured accurately and accurately, providing optimization measures for the next production of the oil field.
In this operation, CNPC logging actively studied the construction details, studied the operation risks, formulated effective measures, and provided on-site guidance from management personnel and technical experts to ensure the safety of the well control and lifting operation of the coiled oil pipe horizontal well profile logging site, and accumulated valuable experience for the subsequent construction. The success of this test marks that CNPC logging has further improved the technology of direct reading of horizontal well and storage production section, and improved the level of coiled pipe horizontal well production section.
