Abstract

The invention provides a shallow gas drilling risk determination method and device and a server. Based on the method, before specific implementation, a quantitative prediction chart of shallow gas pressure and longitudinal wave velocity can be constructed according to experimental test data; by means of the quantitative prediction chart of the shallow gas pressure and the longitudinal wave speed, through numerical simulation, a preset shallow gas risk grade evaluation chart which is good in effect and high in precision is constructed; in specific implementation, depth data of a target area can be firstly acquired; the method also includes transmitting a sound wave signal to the target area so as to acquire a corresponding longitudinal wave speed; and determining the shallow gas drilling risk grade of the target area according to the longitudinal wave speed, the depth data and a preset shallow gas risk grade evaluation chart. Therefore, the shallow gas drilling risk grade of the target area can be accurately and efficiently determined, and the determination error is reduced.

Description

technical field [0001] This specification belongs to the technical field of oil and gas exploration and development, and in particular relates to a method, device and server for determining the risk of shallow gas drilling. Background technique [0002] When drilling operations in environmental areas such as polar cold seas, shallow gas geological disasters are prone to occur, which affects the construction safety of drilling operations. [0003] Based on the existing methods, the qualitative identification of shallow gas geological hazards is mostly obtained and based on 3D seismic data. However, there are often problems such as large errors, low efficiency, and insufficient fineness when implemented based on the above method. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] The embodiments of this specification provide a method, device and server for determining the risk of shallow gas drilling, which can ...
