Abstract

With the deepening of offshore oil exploration and development, low-permeability reservoirs are gradually entering the development plan. Low permeability reservoirs must be commercially exploited by production enhancement measures due to their low production and poor economic efficiency. Therefore, the production enhancement technology mainly fracturing technology has been developed rapidly and also become an important technology for the development of offshore low permeability reservoirs. In this paper, through the investigation, statistics, and analysis of the timing of each part of fracturing construction for medium-sized fracturing wells offshore, we found that the fracturing fluid drainage time is long during the fracturing construction process. The fracturing fluid re-discharge efficiency issue becomes an important factor affecting the fracturing cost and period. Different methods of fracturing fluid drainage are analyzed, and this paper focuses on the applicability of different drainage processes after fracturing in non-self-injected wells. Nitrogen-assisted drainage is preferred as the main means of offshore fracture fluid drainage through analysis. Through the analysis and optimization of the nitrogen-assisted fracturing fluid flowback process, the preferred methods of nitrogen-assisted fluid flowback pressure and auxiliary fluid flowback timing are proposed. Field application and practice show that after adopting nitrogen annular auxiliary drainage process, the fluid flowback volume increases obviously, the oil pressure at the wellhead increases significantly, and the fracturing fluid flowback efficiency improves remarkable.
