Staged Fracturing Of Horizontal Wells Technology And Water Control Fracturing Research

Low permeability oil fields have been used, the use of horizontal wells remaining oil is an effective measure. Fracturing of horizontal wells in particular, can better segment control to tap the potential fracture. China has launched a horizontal well fracturing experimental research, there are almost 100 horizontal wells were fracturing, but restricted horizontal well fracturing technology is not the key to a breakthrough design of staged fracturing optimization, sub-pressure crack tools do not support, restricts the horizontal well technology in the application of low-permeability reservoir. Horizontal well through the low permeability reservoir fracturing technology to improve the low level of penetration of horizontal well fracturing.Low permeability reservoirs in Shengli oil field development and technical conditions of horizontal wells to fracture the target segment, through the horizontal well fracturing optimization study, the choice of construction technology, optimization of staged fracturing and layered string instruments R & D, etc., for the Shengli Oilfield in low permeability fractured horizontal well provides a reliable technical support. Shengli Oilfield low permeability with the main features:multi-layer, heterogeneous, complex relationship between oil and water reservoirs, the way in the development of the energy use of water injection to maintain reservoir development. To this end both the vertical wells or horizontal wells are required for different flow characteristics of reservoir and fracture characteristics of the law extended to study the control of water oil well fracturing technology options to ensure the long-term development after the effect of pressure. Reflect the level of oil field development well in the advantages of low permeability and low permeability formation and improve the technology of horizontal well fracturing technology series, for the low-permeability oil fields developed by horizontal wells to provide new ways to further promote the efficiency of low permeability reservoirs in Shengli Oilfield, continued development.
