Abstract

The invention discloses an intelligent blade lead screw spring supporting leg type vacuum sampler. The intelligent blade lead screw spring supporting leg type vacuum sampler comprises blades (5), a blade shaft (6), a battery (10), a one-way valve (12), an air storing tank bin (13), an air storing tank (14), a plug (16), an upper valve body (17), a spring sheet (18), a stroke recorder (21), blade groove bodies (25), a blade motor (28), a control panel (29), a threaded moving frame (30), a lead screw (31), a supporting motor (33), etc., wherein the blade motor (28) is rotated to drive the blades(5) to rotate so as to control the airing area, and the sampler is accordingly controlled to lift; the rotating movement of the supporting motor (33) is converted into linear movement through screw threads, and the spring sheet (18) is compressed and released to stabilize the sampler at a target layer; and the stroke recorder (21) is used for determining the location of the target layer of the sampler. The sampler has the advantages of being simple in structure, low in cost, and novel in ideal.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to an intelligent suction sampler. Background technique [0002] With the continuous development and progress of oilfield development technology, my country's petroleum industry is currently paying more and more attention to the authenticity and reliability of oil and gas samples from exploration and development oil and gas wells. Obtaining first-hand real and effective oil and gas sample data is of great importance to the exploitation of oil and gas resources. important role. [0003] In the initial stage of gas reservoir exploitation, the downhole pressure of the gas well is sufficient, and the gas flows normally. With the development of the production process, the recovery rate increases and the formation pressure decreases, and the production is often accompanied by the invasion of edge and bottom water and condensate oil. On the one hand, these liquids accumulate slowl...
