Problems solved by technology

Petroleum is mainly used as fuel and gasoline, and is also a raw material for many chemical industry products, such as solutions, fertilizers, pesticides and plastics. When sampling petroleum, it is necessary to drill holes first, and then seal the holes to avoid leakage and pollution. At the same time, sampling is carried out with the help of the sampling tube in the sealing device to ensure the sampling effect, but the position of the common sealing device is not easy to fix and adjust during use, and the stability is poor when sealing the hole, resulting in the sampling quality after sealing. falling problem

Abstract

The invention relates to the technical field of petroleum sampling, and particularly discloses a petroleum sampling packer with good stability. The petroleum sampling packer comprises a sampling pipe body, a filtering membrane and a first fixing ring are arranged on the sampling pipe body, the first fixing ring is located on one side of the filtering membrane, a first clamping pipe is located on the side, away from the filtering membrane, of the first fixing ring, a limiting assembly is arranged on one side of the first clamping pipe, the first clamping pipe is connected with a clamping assembly through the limiting assembly, a plurality of fixing assemblies are arranged on the first fixing ring, a first hole sealing bag, a second hole sealing bag and a third hole sealing bag are fixed to the outer surface of the filtering membrane in a clamped mode, and the second hole sealing bag is positioned between the first hole sealing bag and the third hole sealing bag. Through cooperative use of the first fixing ring and the fixing assembly, the position can be fixed and adjusted before grouting, the petroleum sampling packer is high in stability during hole sealing, the position is not prone to deviation, and the sampling quality after hole sealing is well guaranteed.

Description

technical field [0001] The invention relates to the technical field of petroleum sampling, in particular to a highly stable petroleum sampling packer. Background technique [0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons. It is a viscous, dark brown liquid with a natural appearance. It is called "the blood of industry". Petroleum is divided into crude oil, natural gas, natural gas liquid and natural gas. However, it is customary to use "petroleum" as the definition of "crude oil". There are oil reserves in some areas of the upper crust, and the main components are mixtures of various alkanes, cycloalkanes, and aromatic hydrocarbons, which are one of the main objects of geological exploration. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products, such as solutions, fertilizers, pesticides and plastics. When sampling oil, it is necessary to drill holes first, and then seal the holes t...
