    Dripro Co., Ltd. developed 7" single trip multi-zones big bore and fractured sand control tool in the actual application compared with similar products of domestic and foreign oil service companies, has obvious advanced advantages. The internal diameter of the Dripro's 7" big bore fractured single trip multi-zones sand control tools is 3.88in, which is larger than that of the domestic and foreign oilfield service companies in series 7" sand control tools, also can realize sand-control completion of fracturing filling and is conducive to the application of follow-up production and oil recovery measures and improve the production efficiency of oil companies.
    The development of 7" single trip multi-zones big bore and fractured sand control tool has realized for the first time a high-displacement, high-sand-ratio fracturing filling at all levels in a 7" multi-zones sand control process, which facilitates stimulation measures. The design of big bore allows the 2-7/8" pipeline to pass through, enabling stratified oil production, stratified water injection, and fine reservoir management, providing more choice for the implementation of follow-up production measures;
    From the operations completed on Bohai oil field, the following conclusions can be drawn: The 7” big bore fractured multi-zones sand control tool of Dripro Co., Ltd. is of reasonable design and advanced technology. The technology is mature and safe. Compared with other domestic and foreign companies' 7" multi-zones sand control tools and processes, the technology is advanced and the reliable. Based on the same 5 zones filling workload, the direct saving of the drilling vessel time is 5 days. Party A saved time and increased economic efficiency, and it is worth promoting in the market.
