Problems solved by technology

However, the safety performance of most of the current natural gas drilling equipment needs to be further improved, and the oil blowout technology needs to be improved. The transportation efficiency of natural gas liquefaction after drilling is not very high, and the liquid and gas cannot be separated well.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] Such as Figure 1-Figure 2 As shown, a new type of drilling device for natural gas exploration includes a sampling port 1, a motor 6, a liquid-gas separator 8 and a drilling device 10. The sampling port 1 can extract natural gas, and its upper end is connected with a cooler 2, which can The natural gas is cooled and liquefied. The upper end of the cooler 2 is connected with a filter 3, which can filter out impurities in the natural gas. A check valve 4 is installed in the middle of the filter 3, and the liquefied natural gas can be placed in reverse flow. The check valve 4. A compressor 5 is installed on the outside of the upper end, which can provide hydraulic power by compressing air. The upper end of the compressor 5 is connected with the motor 6, which can provide power for the equipment. The inside of the motor 6 is connected with a stirrer 7, which can be stirr...

Abstract

The invention discloses a new type of drilling device for natural gas exploration, which includes a sampling port, a motor, a liquid-gas separator and a drilling device. The upper end of the sampling port is connected with a cooler, and the upper end of the cooler is connected with a filter. A check valve is installed in the middle of the check valve, a compressor is installed outside the upper end of the check valve, the upper end of the compressor is connected to the motor, the inner side of the motor is connected to the agitator, and the other end of the agitator is connected to the A liquid-gas separator, a blowout preventer is installed on the outside of the liquid-gas separator, a transmission wheel is installed on the upper end of the drilling tool, and a delivery pipe is connected to the upper end of the transmission wheel. The beneficial effect is that the new type of natural gas exploration drilling device can not only drill wells quickly and improve the drilling efficiency, but also carry out liquefaction and transportation of natural gas, filter out impurities, improve the quality of natural gas, and increase the transportation of natural gas efficiency.

Description

technical field [0001] The invention relates to the field of natural gas drilling, in particular to a novel drilling device for natural gas exploration. Background technique [0002] With the wide application of oil and natural gas in industrial life, the extraction technology of oil and natural gas has also been further improved, especially the drilling of oil and natural gas is an important step in oil extraction. Oil and natural gas are buried in rocks with pores, cracks or caves at depths ranging from tens of meters to thousands of meters. In order to find and exploit oil and natural gas, the process of drilling a channel from the ground to the underground oil and gas layers is called oil and gas drilling. After geological investigation and geophysical exploration, select the most favorable drilling position for oil and gas accumulation, and use drilling technology to drill through the oil and gas layers to test geophysical data, understand downhole oil and gas geologic...
