Abstract

The invention provides a plasma generation system and a well drilling method. The plasma generation system comprises a plasma generator and a rock discharging mechanism. The plasma generator is used for crushing rocks. The rock discharging mechanism is arranged on the plasma generator and used for discharging rock debris generated after rock crushing. According to the invention, the plasma generator generates a plasma arc, and the plasma arc acts on the rock at the bottom of the well to break the rock, so that well drilling is realized, mechanical well drilling in the prior art is not needed, a drill bit does not need to be replaced, the well drilling efficiency is greatly improved, and the well drilling period is shortened; and the rock discharging mechanism discharges rock debris generated after rock crushing, so that the rock debris is effectively prevented from blocking the well bottom, smooth drilling is ensured, and the drilling efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a plasma generation system and a drilling method using the plasma generation system. Background technique [0002] In the drilling industry, mechanical drilling is usually used. However, the drill bit wears out quickly in mechanical drilling, requiring frequent lifting and changing of the drill bit, and the entire process of lifting the drill takes a long time, making the drilling efficiency low and labor-intensive. Contents of the invention [0003] In view of this, the present invention proposes a plasma generation system aimed at solving the problem of low drilling efficiency caused by mechanical drilling in the prior art. The invention also proposes a drilling method using the plasma generation system. [0004] In one aspect, the present invention provides a plasma generation system, the plasma generation system includes: a plasma generator and a rock discharge mechanism...
