Research and Treatment of Fracturing for Deep and Complex Fault-Block Fractured Reservoir

This paper demonstrates the fracturing research results and successful treatment of fault-block reservoir in JD, which is the most important exploration and evaluation block in YM oil filed over the past ten years. The research focuses on the prediction technology of formation fracture pressure, the technology of reducing fracture pressure, and the optimization of fracturing fluid system with low friction. Therefore, a set of technologies to reduce wellhead pressure are presented and then applied successfully in 3 wells, all of which have production after treatment. Among them the well C102 has the rate of oil production amount to 21 ton/d. Through these target-oriented technologies, JD block has made great breakthrough.
