Background technology
Shale gas is the natural gas of filling in shale crack, fine pore and aspect, and the permeability of its reservoir is low, the resistance ratios of air-flow tradition natural gas is much bigger, and the exploitation difficulty is larger.According to estimates, China's shale gas resource may reach 45 tcms, and wherein recoverable reserves is about 38 tcms, occupies the first in the world.The main fracturing technology that adopts of shale gas exploitation, make oil-gas Layer form crack, improves the permeability of oil-gas Layer.The fracturing technology process is to use the pressure break pump truck, and the liquid that high-pressure large-displacement is had to certain viscosity is clamp-oned oil-gas Layer, after oil-gas Layer is extruded to many cracks, adds proppant (as quartz sand etc.) filling to enter crack, improves the penetrating power of oil-gas Layer.But fracturing work equipment is many, the content that possesses skills is high, difficulty of construction is large, operating environment is severe, the difficult characteristics of rescuing and escape, and the safety management difficulty increases, and easily causes great casualties and property loss accident.
At present, the Frac unit overwhelming majority that China is used all is in the overage military service stage, its effective power descends, the component fault rate increases, maintenance cost improves significantly, and the operation control system technology still adopts the fracturing control technology of the eighties in last century from external introduction: each pressure break pump truck, manifold truck and fracturing blender truck all need decentralised control, in massive hydraulic fracturing and ultra-large type pressing crack construction, adopt the mode of decentralised control to make the harmony of fracturing work become and more are difficult to control.
The fracturing blender truck signal is sent to measuring truck by stube cable, by data acquisition board and monitoring software for display, shows and to comprise running parameter: density, discharge capacity, various additive amount and pressure etc., in measuring truck, can not control each executing agency of fracturing blender truck.This mode is simple to operate, and the user uses has certain basis.Because stube cable is many, system needs often maintenance, adopts analog-and digital-two kinds of signal transmission forms can not realize the automatic control of complete equipment, and each company of signaling interface and data acquisition software all adopts different forms, is difficult to realize data sharing.
