Research purpose and scope: At present, some Wells in low-permeability oil fields have poor effect by conventional fracturing, and temporary plugging steering fracturing technology has great advantages in fracturing effect, effective use of geological reserves and conventional fracturing ratio. Methods, steps and processes: Through field experiments, statistics of fracturing effect and postcompression production data, analyze the application effect of temporary blocking steering fracturing technology. Results, understanding and conclusion: This technology has significantly increased the production of single well in the low permeability oil field, can repeat the fracturing crack deviation from the original old crack, use the original crack unused reserves, and achieved obvious oil increase effect, which is an effective technical means for the middle and later stage development of the low permeability oil field.
