Description

Geological drill pipe self-contained downhole data acquisition device

technical field

The invention relates to the field of geological exploration, in particular to a geological drill pipe self-contained downhole data acquisition device.

Background technique

Geological drilling is the human use of machines to dig into the ground. The existing geological drilling is equipped with detection equipment at the same time to collect various sensory data during underground drilling in real time.

When drilling into the depth area under the formation, after the detection equipment collects the data, it needs to transmit the data to the computer equipment deployed on the surface through long-distance transmission. However, the data acquisition cycle of detection equipment is frequent, and the amount of detection data jointly generated by different detection equipment is huge, so the collected data is easily disturbed by the external environment under the formation during long-distance transmission, resulting in data loss. After the data loss occurs, the detection equipment needs to transmit data again through long-distance formation interference. The above-mentioned solution to the data loss reduces the efficiency of data collection and subsequent processing on the one hand, and on the other hand, it is difficult to avoid data re-transmission due to long-distance interference. Losses occur in distance transmission.

FIG. 3 shows a schematic flow chart of adjusting the data capacity of the relay pole section 240 in this embodiment. FIG. 3 shows that the adjustment of the data capacity of the relay pole section 240 includes the following steps.

S10 Relay pole section 240 receives probe data from multiple acquisition cycles. The detection data includes the sensor data of various sensor types and the check code calculated based on the data hash of each sensor type.

In the technical solution of step S10 in this embodiment, the relay rod joint 240 keeps receiving detection data without interception, that is, the detection module sends detection data to the ground control terminal 300 according to the communication link provided by the communication drill pipe, and the ground control terminal 300 has no blocked from receiving this probe data. The relay module is coupled to the communication link, and receives the detection data transmitted in the communication link.

S20 The relay pole section 240 is provided with a first storage queue, and the first storage queue sequentially stores the detection data of multiple collection periods with reference to time sequence.

S50 When the ground control terminal 300 fails to verify any detection data, it requests each relay rod section 240 to resend the corresponding detection data stored by itself in sequence from top to bottom according to the length direction of the communicating drill pipe.

S60 When the relay pole section 240 receives the detection data in real time in the first storage queue, it updates the plurality of detection data in its first storage queue according to several rules.

For example, the relay pole section 240 actively sends at least one detection data arranged in front of the first storage queue to the ground control terminal 300 according to a change cycle, and the relay pole section 240 communicates with the ground control terminal 300 to confirm that the detection data arrives. This probe data is erased in real time. Wherein, the change period is at least guaranteed to be longer than the collection period.

For another example, after the relay pole section 240 resends the detection data according to the request of the ground control terminal 300 , the detection data is erased.

Alternatively, relay link 240 is configured with an alternating curve versus drilling depth. This alternation curve exhibits exponential growth with drilling depth.
