Description

Technical Field

[0001] The utility model relates to the technical field of oil processing, in particular to a spare sieve for oil drilling and production. Background Art

[0002] Petroleum is a mixture of gaseous, liquid and solid hydrocarbons with natural occurrence. Its main components are mixtures of various alkanes, cycloalkanes and aromatic hydrocarbons. Oil is a viscous, dark brown liquid and is called "the blood of industry". There is oil storage in some areas of the upper crust, which is one of the main objects of geological exploration.

[0003] The traditional spare sieve for oil drilling and production realizes the solid-liquid separation of drilling fluid through the vibration principle. However, there are still many problems in actual application. When the sieve continuously filters oil and its mixtures, a large amount of impurities and particles will gradually accumulate. As the impurities accumulate, the sieve will gradually become blocked, resulting in a decrease in filtration efficiency and even affecting the entire drilling and production process. There is a need for a design that can discharge the impurities and particles accumulated inside the oil and can recycle the metal ions contained in the oil. Through the ion recovery resin column, this design effectively solves the problem that the metal ions in the oil can be recycled and avoids the possibility of these metal ions blocking the sieve. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spare sieve for oil drilling and production, aiming at the deficiencies of the prior art, so as to solve the problems proposed in the above background art, that is, it can recycle the metal ions contained inside the oil, but the traditional spare sieve for oil drilling and production separates solids from oil through the vibration principle, and when the sieve continuously filters oil and its mixtures, a large amount of impurities will gradually accumulate and block the sieve.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A spare sieve for oil drilling and production, including a workbench. There is an oil barrel arranged at the top end of the workbench. An oil discharge pipe is fixedly installed on the outer wall of the oil barrel.

A belt is installed for transmission between the motor and the rotating rod. A tripod is rotatably installed at the free end of the rotating rod. The outer end of the tripod is fixedly installed on the inner wall of the sieve oil cylinder. Large round holes are opened at both the top end of the workbench and the bottom end of the sieve oil cylinder. A lifting rod is fixedly installed on one side of the workbench. A support rod is fixedly installed at the free end of the lifting rod. A disc is fixedly installed at the top end of the support rod. A fixed disc is fixedly installed at the top end of the disc. Two ion recovery resin columns are arranged at the top end of the fixed disc. A strong acid liquid agent box is arranged at the bottom end of the workbench. The support rod slidably penetrates through the strong acid liquid agent box, and the ion recovery resin column slidably penetrates through the top of the strong acid liquid agent box.

[0006] As a preferred technical solution of the present utility model, a diaphragm pump is provided on the other side of the workbench.
