Abstract
In order to solve the problem that the oil sample can not be extracted since the crude oil is stolen and is solidified under low temperature in the process of extracting the oil in an oil field, the utility model provides an anti-oil theft and anti-freeze sampling valve. The sampling valve consists of a shell, a pressure meter seat, a travelling top thread seat, a travelling top thread, an anti-theft tight connecting core, a sealing rubber ring, a slide connecting steel ball, a sealing screwed plug and a sampling key. A positioning and overflowing channel on the sampling valve is always positioned in the flowing oil liquid, the anti-theft tight connecting core adopts an eccentric body structure to be embedded in the shell of the sampling valve, and the sampling vale only can be opened by a matched tool, thereby achieving the aims of the freeze resistance and the oil theft resistance. The sampling valve is arranged on an oil pipeline at the mouth of a well in a penetration way to extract the oil sample and build the pressure in the oil well. The sampling valve has the characteristics that the volume is small, the operation is simple and convenient, the theft of the crude oil is effectively avoided, the economic loss of the oil field is reduced, the environment pollution is reduced, the maintenance cost of the enterprise and the loss of the material are reduced, the use is safe and reliable, etc.
Description
Technical field
The utility model belongs to the wellhead sampling valve that uses in the oil recovery process of oil field, especially solidifies at low temperatures with crude oil and can't extract the antifreeze sample valve of the employed a kind of guard against theft oil of oil sample at stolen the putting of crude oil.
Background technology
The oil field is wanted constant crude oil in the oil well is extracted oil sample in producing the crude oil process, laboratory personnel by specialty carries out assay to the oil sample that extracts again, so that the effect that increases oily measure that the understanding oil well is implemented in producing the crude oil process and the moisture situation of crude oil are appraised and decided the oil well well yield with this.Therefore on the production flow line of oil well, need to install the antifreeze sample valve of guard against theft oil, the antifreeze sampler of guard against theft oil that existing oil well is installed and used, normally outside the housing of anti-theft sampling valve, add lagging casing, realize the guard against theft oil antifreezing effect of sample valve, but the antifreeze sample valve of existing this guard against theft oil is limited by the well head flow process, generally can only install and use and follow the well head of flow process, can't install and use and mix the well head of failing flow process for employing, and the existing sampler that uses exists volume big, operating personnel carry inconvenience, sampler cost of manufacture height, shortcomings such as on-the-spot mounting process complexity.
The utility model content
It is a kind of simple in structure that the utility model purpose is to provide, and cost of manufacture is low, and is easy to use, safe and reliable, is applicable to the antifreeze sample valve of guard against theft oil of various technological process well heads.
The purpose of this utility model is achieved through the following technical solutions: sample valve is by housing, the pressure gauge stand, and the jackscrew seat that moves about, the jackscrew that moves about, the anti-theft sealing connection-core, O-ring seal, the steel ball that is slidingly connected, the sealing plug, the sampling key is formed; Housing is the pipeline of hollow, location overflow duct perforate is in housing, the fluted C in inner walls surface, the fluted D of anti-theft sealing connection-core external surface, sample valve housing and anti-theft sealing connection-core are sleeved on together, the groove C of sample valve housing is just in time relative with the groove D of anti-theft sealing connection-core, form the slideway of a hollow, housing outer surface has the steel ball load hole, the steel ball load hole leads to slideway, by the steel ball that is slidingly connected that the steel ball load hole is packed in slideway, the anti-theft sealing connection-core is connected also slidably with housing.Sample valve replaces former wellhead sampling valve, sample valve run through be installed on the well head oil pipeline, when extracting the oil sample operation, utilize supporting sampling key to insert in the sample valve housing, screw the sampling key, drive the anti-theft sealing connection-core, and then the anti-theft sealing connection-core drives the jackscrew that moves about, the jackscrew that moves about is separated with the jackscrew seat that moves about, and crude oil flows into the oil-out of sample valve from overflow duct, location, reach the operation purpose of extracting oil sample; The utility model at the oil-out place of sample valve, when the oil well suppressing operation, can screw in pressure gauge stand design on the pressure gauge stand pressure meter, screws the sampling key and opens sample valve, implements the production well operation that normally builds the pressure, and reaches the operation purpose of oil well suppressing.After the extraction oil sample or the operation that builds the pressure are finished, oppositely screw the sampling key, make the move about jackscrew and the jackscrew seat closure of moving about, then can close sample valve.
The beneficial effects of the utility model are: the sample valve volume is little, can run through to install to be connected on the well head oil pipeline, and the overflow duct, location of sample valve is in the mobile fluid all the time, has realized the effect that sample valve is antifreeze.One end of sample valve anti-theft sealing connection-core is designed to eccentric body, is embedded in the sample valve housing, must use supporting sampling key to open during sampling, has realized the purpose of sample valve guard against theft oil.Pressure meter can be screwed on the pressure gauge stand during oil well suppressing operation, replace the cock that builds the pressure that does not possess guard against theft oil, antifreeze function that oil well now often uses, not only solve crude oil and lost problem, also save the cost input of buying and installing the cock that builds the pressure.Sampling key small and exquisite body is light, be easy to carry, and reduced the oil recovery working strength of workers.Sample valve and oil pipeline after the installation are integrated, and the oil well production safety factor is strengthened.Characteristics such as it is little, simple to operation therefore to the utlity model has volume, prevents that effectively crude oil is stolen, reduces the oilfield economic loss, reduces environment pollution, reduces enterprise's maintenance cost and goods and materials loss, safe and reliable.
