Abstract:
The use of electric fracturing equipment for hydraulic fracturing is a new technology for coalbed gas reservoir development, which is still in its early stage of development, and the supporting technology of the fracturing equipment is not yet mature and needs to be perfected. Taking the electric fracturing equipment of coalbed methane in Daning-Jixian block as an example, the integrated configuration method of coalbed methane electric fracturing equipment is put forward according to the requirements of fracturing construction and the operation capacity of the equipment. Specific configuration requirements are put forward from electric fracturing device, power supply and distribution system, frequency conversion room and frequency conversion technology, low pressure manifold liquid supply system, sand transport and sand mixing device, digital fracturing command and control center and high pressure manifold system and other equipment, which are applied in Jishen 4-10 site. The application results show that the proposed method can meet the requirements of high pressure, large discharge, large sand ratio and long operation time, improve the overall operation efficiency and the automation level of equipment, and realize green and low-carbon development. The research results can lay the equipment foundation for fully electric fracturing of deep coalbed methane, and have certain reference significance for the subsequent large-scale promotion.
