Abstract
The invention relates to the field of rock breaking equipment, and particularly discloses a directional variable flow type hydraulic fracturing system. The directional variable flow type hydraulic fracturing system comprises a water tank, a pressure pump, a main controller, a storage battery, a distribution valve, a drilling device and expanders. The invention further discloses a directional variable flow type hydraulic fracturing method using the directional variable flow type hydraulic fracturing system. According to the directional variable flow type hydraulic fracturing system and method, the drilling device is used for drilling a rock wall and collecting hardness data of the rock wall at the same time, the main controller is used for calculating to form the fracturing critical pressure intensity at each fracturing point, then the needed fracturing critical pressure intensity of the expanders at each fracturing point is calculated according to the set time sequence, the main controller controls the flow in the expanders by controlling the distribution valve, and therefore the effect of controlling the fracturing time sequence by controlling the pressure intensity is achieved. The system can adjust measures to local conditions, on-site calculation and deployment are achieved, the intelligence is high, judgment can be carried out without human experience, the safety is high, and the error rate is low.
Description
technical field [0001] The invention belongs to the field of rock breaking equipment, in particular to a directional variable flow hydraulic splitting system and method. Background technique [0002] In the process of quarrying or geological research and exploration, it is usually necessary to cut and crush hard rocks. The transmission method is to process rocks through physical cutting, explosive blasting, digging, etc., but not only the efficiency Low, and the risk is very high, often causing serious safety accidents. [0003] In this regard, people have studied a new type of static rock breaking and cutting technology, that is, hydraulic splitting and cutting rock technology; High-pressure water, controlled pressurization, expands the expander radially, compresses the hole wall, and loads hundreds of tons of expansion force to cause directional cracking or random crushing of rock or concrete structures. Compared with traditional rock-breaking methods, it is safer. Funny...
