Embodiment Construction

[0013] The following examples facilitate a better understanding of the present invention, but do not limit the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified. The test materials used in the following examples, unless otherwise specified, were purchased from conventional biochemical reagent stores.

[0014] like figure 1 As shown, the hydraulically controlled high-pressure environmental liquid sampler of the present invention includes a sealed cylinder composed of a main cavity and a sampling cavity 1 communicating with it, a piston 2, a sampling valve 3, a control valve 4 and a liquid inlet and outlet pipeline 5 . The piston includes a piston head 8 at one end, a polished rod 9 at the other end and a boss 10 in between. The piston head and the boss are located in the main cavity, and the outer edge of the piston head is matched with the inner cavity wall of the main cavity (the piston head is provided...

Abstract

The present invention discloses a hydraulic-control high-pressure environment liquid sampler. The hydraulic-control high-pressure environment liquid sampler of the invention comprises the following components: a sealed barrel which is composed of a main chamber and a sampling chamber (1), a piston (2), a sampling valve (3), a control valve (4) and a liquid inlet/outlet pipe (5). One end of the piston is positioned in the main chamber and divides the main chamber to a liquid inlet chamber (6) and a cushion chamber (7). The other end of piston extends out through an opening on the main chamber. The side surface of main chamber is provided with a liquid inlet which is communicated with the liquid inlet/outlet pipe. The sampling chamber is provided with a sampling opening controlled by the sampling valve. The control valve is installed at the free end of the liquid inlet/outlet pipe. The moving speed of piston can be controlled through controlling the liquid discharge velocity of control valve thereby controlling the flow velocity of high-pressure liquid into the liquid inlet chamber and reducing the shearing of high pressure to the viscosity of liquid. The hydraulic-control high-pressure environment liquid sampler of the invention has the advantages of simple structure and convenient sampling. The shearing caused by the entering of liquid into the sampler in the high-pressure environment can be effectively prevented and the liquid entering into the sampler can be accurately measured.

Description

technical field [0001] The invention relates to a hydraulic control type high-pressure environment liquid sampler. Background technique [0002] As a mature tertiary oil recovery technology, polymer flooding has been applied industrially in many oil fields, and has achieved good results and economic benefits. In field application, the dosing quality of polymer solution is an important factor affecting the displacement effect. Evaluation of polymer quality by wellhead sampling is an important quality control tool in the field. Sampling in high pressure tube pumps is very difficult due to the high pressures involved in injecting the polymer. The traditional sampler is very simple, just a cylindrical container. When the main valve is opened, the polymer solution fills the sampler instantly under the action of pressure, resulting in the shear degradation of the polymer solution viscosity, which cannot truly reflect the polymer The injection quality makes it impossible to effe...
