Field Test And Research On Factory Fracturing Technology

Factory fracturing is a technology using basically fixed fracturing equipments as ordinary factory, do Synchronous fracturing, sequence fracturing or cross fracturing for off-set wells, is a new operation model continues pumping fracturing fluids and proppants. With the successful development of shale gas in North America, has caused global hot exploration and exploitation in unconventional oil and gas, and the frac factory technology first used in North America has also extended. After introduced frac factory technology has been further expanded to the application of tight sandstone reservoirs stimulation.This paper did a lot analyze and research, developed frac factory technology, including FAST hydrating dispersible guar gum fracturing fluid System, online fly blending technology, fine layered fracturing with Packer technology, vertical well fracture height extension rules, packer separate layer fracturing technology, open hole packer staged fracturing technology, multiple crack fracturing technology, simultaneous fracturing and microseismic fracture mapping technology. Carried out the field test in SX-18-20 platform, Put forward a set of frac factory technology based on the fine fracturing design and optimization, and provided guidance for the following SY-82-17 H platform. In SY frac factory fracturing, do research for well selection, wellbore structure design, well fracturing design optimization, keep continues fracturing with continuous fluid&proppant supply, and used fine layered fracturing with Packer technology, Openhole packer staged fracturing technology, multiple crack fracturing technology, simultaneous fracturing and microseismic fracture mapping technology and many other technology.Through the implementation of the frac factory, the fracturing effect is good both in the platform SX and SY, the average daily gas production were significantly higher than that of the original average, while also saving a lot of invest for gas field development, improves the utilization rate of equipment, showing great advantages of frac factory, provides valuable experience for domestic frac factory.
