Multi-directional accurate thickness measurement and sampling device and method for cold finger surface wax deposits

Abstract

The invention provides a multi-directional accurate thickness measurement and sampling device for cold finger surface wax deposits. The device comprises a fixed support base, a support rod, a positioning cone, a clamping ring, a rotating support rod and a measuring cutter. The bottom end of the support rod is installed on the fixed support base; the clamping ring is fixed at the upper part of thesupport rod; and the clamping ring clamps a cold finger. The center of the bottom of the cold finger is abutted against the pointed end of the positioning cone installed on the fixed support base. Oneend of the rotating support rod is in sliding connection with the clamping ring and the other end of the rotating support rod is connected with the measuring cutter. Therefore, the cold finger havingthe surface with wax deposits is fixed and multi-directional accurate measurement and sampling can be carried out on the finger; and the accurate thickness measurement of cold finger surface wax deposits can be performed. Besides, reading reference is performed by a scale rule; and layered sampling of deposits with different thicknesses is realized.

Description

technical field [0001] The invention relates to an accurate thickness measurement and sampling device for wax deposits of crude oil, which belongs to the technical field of crude oil flow assurance in the petroleum industry, and specifically relates to a multi-directional accurate thickness measurement and sampling device and method for wax deposits on the surface of cold fingers . Background technique [0002] At present, with the continuous exploitation of land oil resources, the development of onshore oil fields has gradually entered the middle and later stages, while the development of offshore oil has gradually become a hot spot of common concern in all countries in the world. Offshore oil development is gradually developing from offshore to deep sea, making the temperature around submarine pipelines lower and lower, and the probability of wax deposition is greatly increased. More than 80% of the crude oil produced in my country is waxy crude oil. Waxy crude oil is a c...
