Well Jinji 1 is a key pre-exploration well deployed by Sinopec Southern Exploration and Development Branch in the Sichuan Basin, and drilled by the drilling team of the South Project Department of the Jianghan Petroleum Administration Drilling Company 60413JH
开 During the period from drilling in March 2005 to August, a normal cycle could not be established. 13 types of plugging methods have been used, and a total of 103 plugging constructions have been performed, and a total of 73415.5m3 of working fluid has been lost, which has seriously affected the admission of formation data.
Langzhong Petrochemical Headquarters organized relevant units to hold a demonstration meeting for the serious leakage of the Jinji 1 well. The meeting decided to apply our company's new plugging technology for construction. Low-density expansion high bridge plugs, low-density expansion medium- and high-strength plugging technology and new plug-while-drilling technology were implemented on site to comprehensively plug and reinforce the open hole section, and establish a normal cycle in the shortest time. Based on the geological data, the major technical problems of the malignant leakage of the long naked eye segment were successfully solved.
