| Abstract: | Increasing of deviated well and long-perforated well in Zhongyuan oilfield make near-wellbore effects becoming one of important factors affecting success of fracturing operatons.Adopting proppant slugs technique can decrease effectively the risk of sand plug in fracturing operation and improve the success ratio of fracturing operation.The paper analyzes near-wellbore effects of hydraulic fracturing,and introduces applications of rate step-down test and proppant slugs technique in zhongyuan oilfield. |
