ABSTRACT
The Ordos Basin is rich in tight oil and gas resources, which is an important resource base for 50 million tons of stable production in Changqing Oilfield. However, it is difficult for conventional technical means to develop them effectively. Relying on the national science and technology project “Tight Oil Development Demonstration Project in Ordos Basin”, researchers have conducted the development of a new volume-fracturing tool, aiming at developing a soluble fracturing tool with the core of “metal seal, fast dissolution and drill-free”. Through more than 20 times of formula adjustment and evaluation test, the technical problem of developing soluble metal with high ductility was finally broken through, developing a highly ductile soluble alloy, which broke the conventional rubber sealing method and realized metal sealing. The new fracturing tool solution has obvious advantages and broad application prospects compared with conventional tools.
