Study on Fracture Turning During Temporary-blocked Fracturing in Ansai Oil Field

The stimulation mechanism of the temporary-blocked fracturing technique was researched; meanwhile the precondition for the stimulation of temporary-blocked fracturing was put forward. By studying the main control factors such as reservoir characteristics, crustal stress and initial fracture morphology and so on, initiation and extension of new fracture can be controlled effectively. Field application effect is remarkable, and it has created good economic and social benefits.
