Abstract
The utility model relates to a deaerator which comprises a motor, a delivery outlet, a barrel body, a stirring rod, a mud inlet, a mud outlet pipe and an air dilution opening, wherein the motor is arranged on the upper end of the barrel body, the delivery outlet is formed on the top of the barrel body, and the stirring rod is arranged on the center of the inner lower end of the barrel body by a shaft and is connected with the motor. The utility model is characterized in that a mud partition plate and mud breakage scraps are arranged on the upper part of the stirring rod and are coaxial with the stirring rod, the mud inlet is formed on the bottom of the barrel body, the mud outlet pipe is prolonged to the bottom of a deaeration barrel, and the air dilution opening is formed on the middle part of the barrel body; the deaeration barrel is in the shape of a kettle of which the upper part is small and the lower part is large, and the mud partition plate is annular. The utility model has the advantages that in the process of petroleum exploration and well logging, the deaeration efficiency of the deaerator is raised, and the dead volume of the deaerator is reduced.
Description
Technical field
The utility model relates to a kind of degasser, relates in particular to a kind of degasser that is used for oil exploration well logging process, belongs to the petroleum exploration instrument technical field.
Background technology
Drill returns log is a method of testing commonly used in the present oil exploration, can judge the content of the petroleum gas in the stratum by the hydrocarbons content that contains in the test drilling mud.Accurately whether the data that record depend primarily on the precision of gas chromatograph and the degassing efficiency of degasser.In addition,, in course of conveying, mixes, influence measurement result, just require the dead volume minimum in the system, and tradition degassing barrel structure there is following shortcoming in order to prevent sample because degasser has larger distance apart from chromatograph:
1. the delivery outlet of tradition degassing tube and air water down the top that mouth all is positioned at degasser, during degasser work, sample gas is pumped out from delivery outlet, and a large amount of gas is directly from watering down a mouthful suction, and the sample gas that degasser is deviate from has only sample segment to be sucked away in the bottom of degassing tube;
2. the mud outlet of degassing tube is shorter;
3. traditional degassing barrel shape is circular;
4. after mud was stirred excellent the stirring, the whirlpool dress that can produce at a high speed flowed, and this causes on the mud easily and gushes, and blocks and waters down mouth and delivery outlet.
Because above these shortcomings, make that the degassing efficiency of degasser is lower, the gas of deviating from has part to run off again, and degassing cylindrical shell is long-pending causes bigger dead volume more greatly, and these have all directly influenced the accuracy of logging data.
Summary of the invention
The purpose of this utility model is a kind of degassing efficiency that improves degasser in the oil exploration well logging process of invention, reduces the degasser of degasser dead volume.
For realizing above purpose, the technical solution of the utility model provides a kind of degasser, comprise that motor, delivery outlet, cylindrical shell, stirring rod, mud intake, mud outlet, air water down mouth, motor is located at the cylindrical shell upper end, and delivery outlet is located at the top of cylindrical shell, stirring rod is by being located in center, lower end in the cylindrical shell, be connected with motor, it is characterized in that, on cylindrical shell, be provided with mud and cut apart plate and mud flinders, coaxial with stirring rod, the mud intake is located at the bottom of cylindrical shell; The mud outlet extends to degassing tube bottom; Air waters down the middle part that mouth is located at cylindrical shell.
Described degassing tube is that top is little, the gyalectiform shape that the bottom is big; Described mud is cut apart plate and is shaped as annular.
The utility model is retained in the top with the input port, and will water down the middle part that mouth is changed into degassing tube, makes to water down gas and suck from degassing tube middle part, extracts out from the top again, makes like this to water down gas and can carry sample gas more.
The utility model extends to degassing tube bottom with the mud outlet, because during degasser work, mud by high-speed stirred after, discharge at a high speed from the mud outlet of degassing tube, the mud of discharging can be taken away portion gas, and will can reduce the sample gas of being taken out of behind the outlet lengthening, thereby improved degassing efficiency by mud.
It is little that the utility model degassing tube changes top into, and the gyalectiform shape degassing tube that the bottom is big because the size of bottom is kept intact, makes degassing tube under the situation that the mud amount of handling remains unchanged, and has reduced the unnecessary volume in the tube, has reached the effect that reduces dead volume.
The utility model mud cuts apart plate and the mud flinders can prevent to gush on the mud, prevents to block to water down mouthful and delivery outlet.
The utility model adopts kettle shape degassing tube, and the air of lower position waters down mouth, and the mud of the mud outlet of sealing and annular is cut apart plate, has improved the degasser degassing efficiency, has reduced the dead volume of degassing tube.
The utility model has the advantages that the degassing efficiency that improves degasser in the oil exploration well logging process, reduce the degasser dead volume.
Description of drawings
Fig. 1 is a kind of degasser structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be a kind of degasser structural representation, described degasser is cut apart plate 4, mud flinders 5, stirring rod 6, mud intake 7, mud outlet 8, air by motor 1, delivery outlet 2, cylindrical shell 3, mud and is watered down mouthfuls 9 and form.
Motor 1 is installed in cylindrical shell 3 upper ends, degassing tube 3 is that top is little, the gyalectiform shape that the bottom is big, delivery outlet 2 is located at the top of cylindrical shell 3, and stirring rod 6 is by being located in center, lower end in the cylindrical shell 3, be connected with motor 1, on stirring rod 6 tops annular mud is installed and is cut apart plate 4 and mud flinders 5, coaxial with stirring rod 6, mud intake 7 is located at the bottom of cylindrical shell 3, mud outlet 8 extends to degassing tube bottom, and air waters down the middle part that mouth 9 is located at cylindrical shell 3.
Degasser adopts motor 1 or air motor as stirring power during work, drives stirring rod 6 and rotates; Chromatographic pump is received on the delivery outlet 2 of degasser, bled from degasser, degassing tube immerses mud, and stirring rod 6 is stirred mud, and mud prolongs degassing tube wall and rises and flow out from mud outlet 8; By the stirring and the collision of stirring rod 6, make the gas and the mud separation of carrying in the mud, under the suction of chromatogram pump, water down under mouthful the carrying of 9 air that replenish simultaneously at air, extract out from degassing tube delivery outlet together.
