Coal bed gas fracturing equipment and operation method

Abstract

The invention discloses coal bed gas fracturing equipment and an operation method. The coal bed gas fracturing equipment comprises at least one electric fracturing pump, an electric sand mixing sledge, an instrument sledge, a sand storage tank, a liquid storage tank, a high-low pressure manifold, a variable-frequency power source room and a power transformation and distribution room. The liquid storage tank communicates with the liquid suction inlet of the electric sand mixing sledge and is used for storing fracturing base liquid and conveying the fracturing base liquid to the electric sand mixing sledge; the sand storage tank communicates with the propping agent inlet of the electric sand mixing sledge and is used for storing a fracturing propping agent and conveying the fracturing propping agent to the electric sand mixing sledge; and the discharging port of the electric sand mulling sledge is connected with the input port of the electric fracturing pump through a low-pressure manifold, and the discharging port of the electric fracturing pump is connected with a fracturing wellhead through a high-pressure manifold. According to the coal bed gas fracturing equipment and the operation method, the coal bed gas fracturing equipment and the operation method can be used for solving the problems of high energy consumption, high noise, large occupied area, high pollutant emission, high long-term operation and maintenance cost and the like of traditional coal bed gas fracturing operation equipment.

Description

technical field [0001] The invention relates to the field of coal bed gas development, in particular to a coal bed gas fracturing equipment and an operation method. Background technique [0002] Existing CBM fracturing operations mostly use the main pumping and pressurizing equipment used by diesel fracturing units. This equipment has problems such as high energy consumption, high noise, large floor space, and high pollutant emissions. Hydraulic fracturing, as one of the coalbed methane stimulation technologies, can effectively reduce the seepage resistance of the formation near the bottom of the well, and change the flow pattern of coalbed methane from radial flow to bilinear flow. Through the transformation of hydraulic fracturing technology, the economic production capacity of coalbed methane can be effectively improved. At present, coalbed methane hydraulic fracturing operations mainly use diesel fracturing crews, sand mixing trucks, instrument trucks, fracturing manifo...
