Power causes rock surface to generate crack until cracking.This method is primarily targeted for the exploitation of geothermal energy resources.
With reference to fluid pyrolysis technology, seminar proposes heating power jet stream rock breaking method, i.e., in fluid pyrolysis technology
On the basis of, by structure of reactor under planned well, redesign injection parameter etc., improve high temperature thermal medium speed (>100m/
S), so that catalase not only has the percussion of thermal cracking effect, also jet stream.It improves comprehensive with cracking by impact
Cooperation is used, and be may act on a greater variety of rocks, is obtained faster broken rock speed, so as to improve the drilling well of deep well hard formation speed
Degree.
For heating power jet stream rock breaking method, one of core is the structure design of underground reactor, with fluid thermal cracking
Technology is compared, injection rate and the raising to muzzle velocity, and requirements at the higher level are proposed to the design of underground structure of reactor.Have
Heating power jetting method in, only provide simple underground reaction unit mentality of designing, only rest on the theoretical conceptual phase, can use
It is urgently furtherd investigate in the underground structure of reactor design of heating power jet stream.
Moreover, the design of reaction cavity configuration is one of critical issue of heating power jet stream drilling well.The uniformity coefficient of fuel mixing,
The effect of tube wall cooling all has a major impact the efficiency of tool and service life.Fuel mixing is more uniform, and reactant reaction degree is got over
Completely, implement productivity is higher；Tube wall cooling effect is better, and the tool up time is longer, and the service life is longer.
