Abstract

Abstract: To study the serious formation damage caused by the drilling fluid of drilling operations in the East China Sea area, an intrusion depth study of the drilling fluid into tight sandstone in an area of the East China Sea was performed. The resistance test method and the volume method were used in the study. The resistance of the core sample during the penetration of drilling mud and the maximum penetration volume of the filtrate of the drilling mud were measured. Based on the relationship between the resistance, penetration volume and the time, the relationship between the penetration depth and the time was obtained via fitting and the penetration depth of the drilling fluid was calculated. The penetration depth of the drilling fluid into a core sample of the tight sandstone matrix in the lower section of the Huagang Formation was obtained. The penetration depths of the drilling fluid calculated using resistance measurement and the volume method were 34～49 cm and 30～56 cm, respectively. The degree of formation damage after penetration of the drilling fluid was 78.2%～97.9%, and the damage degree was strong. This experimental study provides a basis for controlling the filtration loss and reducing the formation damage during drilling and completion operations in the East China Sea area.

Key words: tight sandstone, reservoir damage, drilling fluid, penetration depth, resistance test
