Completion technology and cementing quality analysis for exploration wells in Shengli Oilfield

Shenli Oilfield has moved into a new stage of taking subtle reservoir as main exploration targets. Key targets of reserve increasing and production raising lie on complex reservoir formations with super-low permeability, low reserve abundance, low formation pressure low production, and high formation pressure low permeability. However, the completion and cementing technologies for subtle reservoir are difficult. By analyzing the completion technology and cementing quality of exploration wells within the recent 5 years, the factors affecting cementing quality was found, and the pointed technical treatment was proposed. It provides good conditions for the oil production task completion during the twelfth 5 years and some while later.
