An Intelligent Umbrella Gear Rack Outrigger Differential Sampler

Abstract

The invention discloses an intelligent umbrella-shaped gear-rack supporting leg differential type sampler. The sampler comprises a lead screw-nut mechanism (3), an umbrella frame (4), a motor A (10),a travel recorder (12), a control center (14), a battery (16), a gear shaft (21), a cylinder (23), a piston (25), a valve core (29), a lead screw (33), a rack (35) and the like; the travel recorder (12) is adopted to determine the stratum position of the sampler; the lead screw-nut mechanism converts rotary motion into linear motion, so as to unfold and fold the umbrella frame (4), so that a windcatching area can be controlled, and the lifting and lowering of the sampler can be controlled under the action of airflow; with a gear-rack mechanism adopted, the rotary motion of the gear shaft (21)can be converted into the linear motion of the rack (35), so that the fixed position of the rack (35) can extend out; and the force bearing areas of two ends of the piston (25) are different, so thatthe piston (25) is moved up, and gas collection can be completed. The sampler of the invention has the advantages of simple structure, low cost and high creativity.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a natural gas development sampler. Background technique [0002] With the continuous development 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 production is often accompanied by the invasion of edge and bottom water and condensate oil. On the one hand, these liquids slowly accumulate at the bottom of the well, hindering the movement of gas to the wellhead, and ...

Problems solved by technology

This is very harmful to the exploitation of natural gas. In the slightest, it will reduce the output, and in the worst case, it will lead to fluid accumulation in the wellbore, water flooding, spraying stop, etc.
