Abstract

An ultrasonic laser drilling device is characterized in that the ultrasonic laser drilling device comprises a cooling unit (1), a control unit (2), a communicating pipe (3), a filter tank (11), a high-power pulsed laser array (4), a plurality of ultrasonic generators (5) and an ultrasonic focusing array (6). A cable, a high-strength water pipe and a water returning pipe are arranged in the communicating pipe (3); the cable in the communicating pipe (3) enables the control unit (2) to be connected with the high-power pulsed laser array (4), the multiple ultrasonic generators (5), the ultrasonicfocusing array (6) and air pumps (9) in a shell (12) on the lower portion; and the high-strength water pipe in the communicating pipe (3) enables the cooling unit (1) to be connected with a cooling water circulation system of the high-power pulsed laser array (4), the ultrasonic generators (5) and the ultrasonic focusing array (6). The high-power pulsed laser devices emit high-pulse energy, and the ultrasonic generators damage the rock structure through the focusing array, so that rock breaking drilling is achieved, and the effect is good.

Description

technical field [0001] The invention relates to the field of oil and gas exploitation and laser application, in particular to an ultrasonic laser drilling device. Background technique [0002] Oil and natural gas is the main applied energy in the world today, and it is the most widely used ore energy in modern industry and life, and the exploitation of oil and natural gas has become the key technology among them. Rotary drilling technology is a drilling method widely used in oil and gas exploration and development at present. , with the complexity of stratum and rock formation and the increase of drilling depth, the drilling cost will increase accordingly. At the same time, the structure of various strata and rock formations is different during the drilling process. When encountering hard stratum and rock formations, mechanical drilling is often not competent. It also brings various problems. Therefore, there is an urgent need for an efficient drilling method. According to ...
