Problems solved by technology

[0004] The purpose of the present invention is to provide a petroleum geological exploration sampling device and method in complex surface areas, aiming to solve the problem that the geological acquisition device in the prior art usually drives the relevant tools into the ground, then takes the tools out of the soil, and then removes the tools from the tools. However, it is impossible to accurately sample the soil at the required depth in the ground, which affects the accurate analysis of soil samples and reduces the technical problems of survey results

Abstract

The invention relates to the technical field of geological exploration equipment, in particular to a petroleum geological exploration sampling device and method for a complex surface area. When geology of different depths is sampled, adjusting assemblies below two supporting columns are adjusted, a positioning needle is inserted into the ground, and a stabilizing rod is stabilized; a motor of each sampling assembly is started, the motors drive lead screws to move a sampling box downwards, and then a fixed drill bit below the sampling box is driven to rotate; punching is conducted on the ground, and punching is conducted deep into the earth surface; a depth sensor senses the depth, and a micro cylinder is started to drive an extension rod to contract; and when the sampling box rotates, the extension rod pulls a sliding door to move upwards, and when the sampling box rotates, the soil enters the sampling box along with an opening in the side edge of the sampling box, the soil at different depths can be collected.

Description

technical field [0001] The invention relates to the technical field of geological exploration equipment, in particular to a sampling device and method for petroleum geological exploration in complex surface areas. Background technique [0002] Petroleum exploration is to find and ascertain oil and gas resources, and use various exploration methods to understand the underground geological conditions, understand oil generation, oil storage, oil and gas migration, accumulation, preservation and other conditions, comprehensively evaluate oil and gas prospects, and determine the location of oil and gas accumulation. In favorable areas, it is the process of finding oil and gas storage traps, ascertaining the area of ​​oil and gas fields, and finding out the situation and production capacity of oil and gas layers. [0003] In petroleum geological exploration work, it is often necessary to collect soil samples in order to directly observe or analyze the natural state of rock and soi...
