Description

Technical Field

[0001] The present invention relates to the technical field of shale oil and gas exploration, and in particular to a gamma unmanned aerial vehicle and a shale field profile stratigraphic division system and method. Background Art

[0002] Shale gas is an unconventional oil and gas resource that has attracted much attention. Different from conventional oil and gas resources, shale gas refers to natural gas that exists in dark mudstone in both adsorbed and free states. The organic matter and clay minerals in shale have strong adsorption capacity for radioactive elements such as U, Th, and K. In particular, K and Th are mainly related to the adsorption of fine-grained sediments (the finer the particles, the more radioactive substances are adsorbed). Therefore, shale sections often show strong radioactive characteristics.

[0003] Based on the continuous gamma signal value of the shale layer, the shale field profile can be divided into strata. The division of shale strata on the field profile has important scientific and practical significance for the prospecting of shale gas in the mining area, but most of the shale profiles in the field have problems such as severe weathering and erosion. At the same time, many shale field profiles are located at the riverside, cliff slopes, etc. The commonly used handheld gamma gun detection method is difficult to play a role in many cases, and it is impossible to measure gamma information and stratify shale strata. Summary of the invention

[0004] To solve the above problems, the present invention provides a gamma drone and a system and method for shale field profile stratigraphic division. The gamma drone can perform gamma measurement and data collection on shale field profiles in areas that are inaccessible to humans. The measured gamma data can provide a good basis for stratigraphic division, thereby providing a technical basis and data verification for shale gas exploration area selection and drilling of shale target layers.

[0005] The present invention provides a gamma drone, and the specific technical solution is as follows:

[0006] It includes a drone device, a Bluetooth control module, a communication module, a micro drilling device, a gamma device, and a laser radar device;

[0015] The drone control module is remotely connected to the Bluetooth control module to remotely control the operation of the Gamma drone;

[0016] The data receiving module is remotely connected to the communication module and is used to parse and output the data information transmitted by the communication module;

[0017] The parameter setting module is used to adjust the operating parameters according to the actual situation of the profile and transmit the parameter data to the Gamma UAV;

[0018] The data analysis module uses third-party geological software to extract, process and analyze the gamma data collected and transmitted by the gamma drone to obtain a two-dimensional energy spectrum.

[0019] The survey output module outputs shale formation division data based on the two-dimensional energy spectrum.

[0020] Furthermore, the operating parameters include measurement interval, measurement quantity and frequency.

[0021] Furthermore, the shale field profile stratigraphic division system also includes a cloud server, which is remotely connected to the ground survey system to store data and synchronize the shale stratigraphic division data to the terminal.

[0022] The present invention also provides a shale field profile stratigraphic division method, based on the above-mentioned shale field profile stratigraphic division system, comprising:

[0023] S1: Send control instructions to the Gamma UAV through the UAV control module. After receiving the control instructions, the Bluetooth control module controls the Gamma UAV to reach the target area;

[0028] S6: adjusting the operating parameters, repeating the drilling and gamma data collection, and feeding the collected gamma data back to the ground survey system;

[0029] S7: The ground survey system calls third-party geological software to analyze the data, obtain a two-dimensional energy spectrum map, and output shale formation division data based on the two-dimensional energy spectrum map.

[0030] Furthermore, step S2 also includes acquiring image data of the target area using a camera, and transmitting the data to the ground survey system through a communication module.

[0031] Furthermore, in step S3, the sampling points are evenly linearly distributed.

[0032] Furthermore, in step S5, the shale formation is drilled 2-5 cm deep to continuously collect signals of fresh shale samples.

[0033] The beneficial effects of the present invention are as follows:

[0034] Through the unmanned aerial vehicle system equipped with laser radar, gamma meter and micro-drilling equipment, continuous measurement of gamma signals of complex shale formations is achieved.
