Configuration and Operation Technology of Fully Electric Fracturing Equipment for Shale Oil
The use of electric fracturing equipment for hydraulic fracturing is a new technology for shale oil reservoir development,which is still in its early stage of development,and the supporting technology of the fractu-ring equipment is not yet mature.Taking the electric fracturing equipment of Shengli shale oil as the research ob-ject,combined with fracturing requirements and equipment capacities,an integrated configuration method for elec-tric fracturing equipment of shale oil was proposed.Specific configuration requirements were proposed for equip-ment such as fracturing device,sand transport device,sand blending facility,automatic fluid feed system,variable frequency control system,instrumentation control center and high-pressure manifold system,which have been ap-plied in 8 wells of Fanye 1 test unit in Shengli oilfield.The application results show that the formed supporting method meets the requirements of shale oil fracturing with high pressure,large displacement,large sand concentra-tion and long operation time,and can improve the overall operating efficiency and equipment automation level,a-chieving a green and low-carbon development.The research results lay an equipment foundation for large-scale e-lectric fracturing construction of shale oil,and have certain reference significance for subsequent large-scale popu-larization.
