Drilling Practice of New 120-80 Sidetrack Horizontal Well

Abstract:

In order to explore effective development adjustment method for fractured low permeability oilfield, mitigate production decline and improve ultimate recovery, sidetrack horizontal well tests were made on long time shutin oil and water wells to improve oil extraction rate and producing degree of residual oil, which provided technical basis to the followup adjustment for low abundance, low permeability fractured oil field.
