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.

Embodiment Construction

[0020] After the downhole logging is completed and the downhole sampling depth is determined, the well layer data is imported into the sampler and the sampler can be lowered; during the fall of the sampler, the travel recorder can measure the falling depth and transmit the data to the control The electric board, the upper control electric board adjusts the opening of the umbrella stand according to the falling depth and then changes the falling speed of the sampler, so that the sampler just stops falling when it reaches the designated sampling position. At this time, the sampler is under the action of gravity and rising buoyancy The lower end is suspended at the sampling position; then, the lower control board controls the lower rotating motor to work, and the movable outrigger moves down to compress the fixed spring to open and fix the sampler; after the sampler is fixed, the lower control board controls the hollow motor to work , the nut screw mechanism drags the piston up to...

Abstract

The invention discloses an umbrella-shaped motor-driven underground intelligent sampler and belongs to the technical field of underground sampling devices. The umbrella-shaped motor-driven undergroundsampler mainly comprises a salvaging module, two power modules, two control modules and respective execution modules. The falling, fixing and sampling processes of the umbrella-shaped motor-driven underground intelligent sampler are automatically controlled, people only need to put down the sampler and carry out salvaging operation, and then running of a vertical rotating motor can be automatically controlled in order to adjust the opening degree of ribs and extend or retract leaf springs, so that the speed is changed, and the sampler is fixed; then, the hollow motor is controlled to run to pull a piston for collection of gas. The umbrella-shaped motor-driven underground intelligent sampler basically realizes automatic control in the whole process and is simple in structure and convenientto operate, and gas different in pressure in different underground layers can be sampled.

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 slowly...
