Research On The Ultra-Deep Fracturing Technology In Songnan Area

The deepening of the Songnan area is one of the key areas of Sinopec exploration and development in recent years. It is of great significance to solve the deep fracturing problems in the Songnan area. The deep reservoirs in the Songnan area are complex and the reserves are large and belong to the deep and ultra-deep ultra-low permeability reservoirs. Fracturing is one of the most aggressive measures to increase the permeability of the low permeability reservoirs.Songnan area in recent years, one of the key of Sinopec exploration and development is to solve the problem of fracturing technology in southern Songliao Basin, which is of important significance for oil and gas development in Songnan area. The need to strengthen and deepen understanding, combined with the engineering geological characteristics of rock reservoir volcano volcano rock reservoir, establish rupture and extension model of volcano rock fracturing design and basic research, field control technology and other studies are needed to further capture, form the southern Songliao basin gas reservoir fracturing technology, improve the yield increasing effect of deep fracturing in southern Songliao basin.In order to have more scientific and targeted deep reservoir stimulation technology, it is urgent to develop a complete set of high performance fracturing technology to achieve a huge production in the deep oil and gas reservoirs.In this paper, the ultra-deep fracturing process technology is studied in this paper, and the research on the anti-high temperature fracturing fluid system, the selection of wells and the design optimization are carried out, and the construction pressure and fracture pressure are studied in detail. Study on the Technology of Large - scale Sand Matching..
