Description
Technical field
The present invention relates to technical field of petroleum extraction, and in particular to a kind of hydraulic fracturing continuously matches somebody with somebody liquid with fracturing fluid big flow
System and with liquid method.
Background technology
Hydraulic fracturing is a kind of widely applied yield-increasing technology method in the outer oil gas field stimulation process of Current Domestic.Pass through
Pressure break can formation length is suitable, flow conductivity is strong crack, and then link up and lead to the oil storage space and seepage flow for being connected oil gas
Road, smooth so as to fulfill oil gas field go into operation and give stable high yields irrespective of drought or water logging.
Fracturing fluid mainly has three kinds with liquid using the mode of production at present, i.e. traditional approach, scene is matched somebody with somebody with liquid mode, automation
Liquid mode：
(1) traditional approach：After the preparation that fracturing fluid is completed in make-up station, fracturing fluid is transported to operation by transportation tank car
Scene, which cost of transportation is high, is only applicable to nearly well pressure break and matches somebody with somebody liquid.
(2) liquid mode is matched somebody with somebody at scene：Single tank is carried out by some simple devices at fracturing work scene and operating personnel to match somebody with somebody
Liquid, this to have the shortcomings that hand labor intensity is big, liquid preparation time is long with liquid mode, the operating environment with liquid mode is poor,
The work flow of mixed batch is criticized also to be easy to cause the putrid and deteriorated of fracturing fluid and waste.
