| titleOfInvention | A kind of spontaneous hydrochloric acid acidization tool suitable for carbonate reservoir |
| abstract | The invention discloses a kind of spontaneous hydrochloric acid acidization tool suitable for carbonate reservoir, comprise the following steps successively：（1）Water, monoxone are added into Agitation Tank, is uniformly mixing to obtain A agent chloroacetic acid solutions, the mass ratio of monoxone and water is 1 ~ 8:1；（2）Phenol, butyl glycol ether are separately added into Agitation Tank, adds water, treats that all dissolving obtains B agent phenol liquid to phenol, the mass ratio of phenol, butyl glycol ether and water is 1 ~ 8:0.1~1:1；（3）High pressure makes formation fracture to reservoir injection fracturing fluid；（4）A agent is first poured into inside carbonate reservoir；（5）B agent is injected to inside carbonate reservoir, and the mass ratio of monoxone and phenol is 1:1；（6）Displacement fluid is injected to pit shaft, the B agent in pit shaft is headed into reservoir deep.The present invention can effectively improve deep penetration ability of the acid solution to carbonate reservoir, so as to transform reservoir deep, improve oil gas field yield. |
