[0037] Reference Figure 1 According to an embodiment of the present invention, a drilling device 100 includes: a drill bit 90, a drilling tool 91 and a measuring structure 92.

[0038] The drill bit 90 is used to contact and break the stratum.

The measuring structure 92 is provided between the drill bit 90 and the drilling tool 91 to measure the data of the stratum.

[0039] During the drilling process, the drilling device breaks the formation through rotation and thrust to achieve deep hole drilling. In order to accurately control the drilling trajectory and obtain formation information in a timely manner, the drilling device is usually equipped with a measurement structure. The measurement structure is used to detect the physical properties and structural changes of the formation in real time, thereby providing data support for the positioning and trajectory adjustment of the drilling device.

[0040] However, in the prior art, the real-time data feedback of the measurement structure has certain lags and errors. For example, when the head of the drilling device is entering the reservoir, the measurement structure fails to reflect the relevant information of the reservoir in a timely and accurate manner. This problem may cause a large deviation between the measured data and the actual formation, thereby affecting the precise positioning and trajectory adjustment of the drilling device. Due to the untimely and inaccurate measurement data, the drilling trajectory may deviate or fail to meet the predetermined development requirements, thereby reducing the efficiency and accuracy of the drilling operation. This problem is particularly prominent in efficient formation development and precision drilling, so it is urgent to improve the existing measurement structure to improve the formation information acquisition speed and measurement accuracy during the drilling process.
