| titleOfInvention | Exploration process of superficial layer natural gas |
| abstract | The invention relates to an exploration process of superficial layer natural gas. The exploration process of the superficial layer natural gas comprises early reconnaissance and a field test. In a reconnaissance process, a home-made exploration head is connected with an exploration rod to arrange a static penetrometer; the exploration head is always in connection with the exploration rod in the pressing process of the static penetrometer; and when the static penetrometer is at an appoint position, the exploration rod is lifted, the exploration head and the exploration rod are automatically separated, gas at this moment can be vented from a central channel of the exploration rod, and if the air pressure and the flow are small, a BXC-02 combustible gas detection alarm is used to detect whether gas overflows at an opening of the exploration rod or not. In the field test, a static pressure device is firstly used to press the exploration rod into a preset depth under the ground in order to accurately measure the burial depth of a bottom plate with an air layer, then the exploration rod is lifted to examine whether gas overflow exists or not, if gas overflow exists in the lifting process, the depth with gas overflow is the burial depth of the bottom plate with the air layer. |
