Description

A kind of anticorrosion withstand voltage core holding unit
Technical field
The utility model relates to petroleum-based energy technical field, is specifically related to a kind of anticorrosion withstand voltage core holding unit.
Background technology
As everyone knows, develop sequence is the basis of oil-gas field development, can not only calculating for the reserves of hydrocarbon-bearing pool, development plan establishment, the work such as numerical reservoir simulation provides basic oil deposit parameter, can also ensure for solving in oil reservoir development the many problem supplying methods run into.Core holding unit is purposes one of infrastructure component the most widely in develop sequence, and nearly all develop sequence all will use core holding unit.
Core holding unit as a kind ofly clamping and seal rock core, complete rock permeability, the special arrangement of factor of porosity test or various rock core displacement test, its major function puts into wherein by rock sample to be measured or to be tested, and when ensureing that test fluid flow passes through core sample rear and front end, the side surface of rock sample can be sealed up completely.Its function ratio is more single, mainly concentrates on core test purposes.Due to the complicated variety on stratum, the primal environment on each stratum is different, also different to the requirement of core holding unit.
Summary of the invention
The purpose of this utility model is to provide the anticorrosion withstand voltage core holding unit that a kind of life-span is long, conform.
In order to realize above object, the utility model is by the following technical solutions: a kind of anticorrosion withstand voltage core holding unit, it comprises pressure-bearing cylinder 1, sleeve 2, bonnet 3, to exert pressure port 4, to exert pressure described in the side of described pressure-bearing cylinder 1 outer-rear end is provided with port 4, the inside of described pressure-bearing cylinder 1 is provided with described sleeve 2, and the two concentric, movable drain plug 5 is provided with in the front end of described pressure-bearing cylinder 1, fixing plug 6 is provided with in the rear end of described pressure-bearing cylinder 1, described movable drain plug 5, the external diameter of fixing plug 6 is equal and be not more than the internal diameter of described sleeve 2, described movable drain plug 5, the outside of fixing plug 6 is equipped with pressure cap 7, described fixing plug 6 inside is provided with ring seal circle 8 and distribution plug 9.
Further, described pressure-bearing cylinder 1 adopts material to be the steel high pressure seamless pipe manufacture of 1Cr18Ni9Ti.
Further, described sleeve 2 adopts acid and alkali-resistance rubber to make.
Further, described movable drain plug 5 can install pressure measurement pipeline, and temperature probe can be established in inside.
The utility model has following beneficial effect: the utility model integrated model is simply exquisite, and shell employing material is the steel high pressure seamless pipe manufacture of 1Cr18Ni9Ti, firm high pressure resistant; Inner sleeve adopts acid and alkali-resistance rubber to make, preserving and sealing.
