文档介绍:断 块 油 气 田
第 卷第 期 断 块 油 气 田 multiply fractures development, serious fracture fluid filtration loss and the
problems of post fracturing fluid recovery backflow and oil flowing during production. Using systematic optimization procedure,
coupled with the fracture morphology prediction, fine classification of reservoir geologic feature, optimal selection of fracture
parameters, ball-off separate layer fracturing and construction pressure prediction etc, a set of integrated optimization design method
and fracturing technology has been formed, which is suitable for long perforation section of horizontal well and with low cost.
Through the application of fracturing with large discharge and high viscosity pad, it uses ceramic grinding pore and lowering
filtration, optimizing fracturing fluid properties, and also using lower density proppant to ensure the construction sucessful. Test
results show that 4 set of frctures have been formed. Daily production increases from to 20m3/d and good effect on
increasing production has been obtained.
Key words: horizontal well, multi-interval fracturing, orientation of earth stress, optimal design, field application.
