| titleOfInvention | A kind of temporary stall based on the modified vinal in surface is to fracturing process |
| abstract | The present invention specifically provides a kind of temporary stall based on the modified vinal in surface to fracturing process, comprises the following steps：1) surface modified aqueous vinal；2) preparation of fracturing working fluid；3) using active water for extrusion well liquid within the cartridge；4) setting fracture packer；5) prepad fluid is injected, major fracture is formed；6) the major fracture staged to formation injects water-soluble biodegradable fiber temporarily stifled fracturing fluid, and injection stratum forms new branch's seam；7) to the new branch seam injection prepad fluid of formation, seam length is expanded；8) to the new branch seam staged injection load fluid of formation；9) with active water for load fluid in extrusion pit shaft.The invention is by the way that sand packed fracture is temporarily blocked up by old crack or, with making new seam on primary fracture at an angle direction, link up more intrinsic fractures and region is not employed in first crack, form new crack aerial drainage system, oil and gas production and oil gas field ultimate recovery are improved, the problem recovered old well production and realize new well fracturing yield increasing is solved. |
