Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Please also refer to Figure 1 to Figure 5Now, the roller cone bit with geological image acquisition and formation sampling functions provided by the present invention will be described. The roller cone bit with the functions of geological image acquisition and stratum sampling includes a bit body 1, a sampling mechanism 2, an image acquisition component 3 and a control system 4, and the end of the bit body 1 away from the roller cone is provided with a cavity 5, which is located in the cavity. The outer wall of the drill body 1 outside the cavity 5 is used...

Abstract

The invention provides a roller bit with geological image collecting and stratum sampling functions, and belongs to the technical field of roller bits. The roller bit comprises a bit body, a sampling mechanism, an image collecting assembly and a control system; the bit body is provided with a cavity; a sampling channel is arranged in the bit body along the height; the sampling mechanism is slidably arranged in the sampling channel, moves in the height direction of the bit body and can drill into the stratum to take out a stratum sample; the image collecting assembly is arranged on the sampling assembly and collects geological image information; and the control system receives image information collected by the image collecting assembly and controls the sampling assembly to operate. The roller bit with the geological image collecting and stratum sampling functions has the technical effects that the sampling mechanism and the image collecting assembly are integrated on the roller bit, the geological image collecting and stratum sampling operation is convenient and flexible, the image collecting and sampling efficiency is high, and the bit does not need to go in and out of a shaft back and forth.

Description

technical field [0001] The invention belongs to the technical field of roller cone bits, and more specifically relates to a roller cone bit with the functions of geological image acquisition and formation sampling. Background technique [0002] The roller cone bit is currently the most widely used rock-breaking tool for oil drilling, and its use effect and working life have a very important impact on drilling construction and drilling costs. The roller cone bit in the prior art only has the function of drilling into the rock formation, and cannot realize the functions of collecting the geological image inside the wellbore and sampling the formation. Then when it is necessary to collect the geological image inside the wellbore or sample the formation , you need to use professional image acquisition equipment and stratum sampling equipment, and use tools such as drill pipes to send image acquisition equipment and stratum sampling equipment into the inside of the wellbore in or...
