Abstract
The utility model proposes a kind of degasser that can keep draft, comprise degasser body, described degasser body surface is provided with buoyant device, also comprise support, described support is provided with the pulley that both direction is identical, described pulley is provided with drag rope, described drag rope one end connects degasser, the other end and the first balance weight body mount, and also comprise the second balance weight body that several and the first balance weight body vary in weight.A kind of degasser that can keep draft of proposition of the present utility model, when drilling liquid changes, degasser will be automatically found equalization point under the effect of balance weight body and buoyancy, when liquid level fluctuates up and down, degasser will allow the drinking water of degasser substantially keep a definite value with liquid fluctuating, thus improves the judgement of degasser to the accuracy of data and oil-gas Layer character.A kind of degasser that can keep draft of proposition of the present utility model, structure is simple, easy to use, is adapted at promoting on a large scale in compound logging work.
Description
Technical field
The utility model relates to a kind of degasser that can keep draft in compound logging work.
Background technology
Degasser in compound logging work analyzes and finds oil-gas Layer important tool, and the quality of its work directly affects the accurate of data, and applicant finds on the accurate of data and oil-gas Layer character, the depth of its draft judges that impact is very large at work.Now along with the application of drilling well new technology, such as pumpage change makes the change of its drilling liquid larger, the existing degasser adopted lean on artificial secured adjusted to heavens method can not meet need of work.
Utility model content
For shortcomings and deficiencies in prior art, the purpose of this utility model proposes a kind of structure simply, and can keep the degasser that can keep draft of certain draft.
Draft is that definite value can reach degassing efficiency, and can reach can quantitative degassed object simultaneously, to discovery oil-gas Layer with judge that oil-gas Layer character has great help.
In order to achieve the above object, the utility model proposes a kind of degasser that can keep draft, comprise degasser body, it is characterized in that, described degasser body surface is provided with buoyant device, also comprise support, described support is provided with the pulley that both direction is identical, between described two pulley levels, there is default spacing distance, described pulley is provided with drag rope, described drag rope has default length, described drag rope one end connects degasser, the other end and the first balance weight body mount, described first balance weight body weight is less than the weight sum of degasser and buoyant device,
Also comprise the second balance weight body that several and the first balance weight body vary in weight, the weight of described second balance weight body is greater than respectively and is less than the first balance weight body, when the proportion of drilling fluid changes, buoyancy also can change, interchangeable breeding body is original definite value to regulate the weight of balance weight body to keep degasser to absorb water, when drag rope and the second balance weight body mount, described second balance weight body weight is less than the weight sum of degasser and buoyant device.
Preferential as technique scheme, described buoyant device is the sealed compartment being arranged at degasser surface.
Preferential as technique scheme, described buoyant device is buoyant spheres.
A kind of degasser that can keep draft of proposition of the present utility model, when drilling liquid changes, degasser will be automatically found equalization point under the effect of balance weight body and buoyancy, when liquid level fluctuates up and down, degasser will allow the drinking water of degasser substantially keep a definite value with liquid fluctuating, thus improves the judgement of degasser to the accuracy of data and oil-gas Layer character.When the proportion of drilling fluid changes, buoyancy also can change, and at this moment we can regulate the weight of balance weight body to be original definite value to keep degasser to absorb water.A kind of degasser that can keep draft of proposition of the present utility model, structure is simple, easy to use, is adapted at promoting on a large scale in compound logging work.
Accompanying drawing explanation
Fig. 1 is the degasser structural representation that can keep draft of utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of degasser that can keep draft that the utility model proposes, comprise degasser body 1, described degasser body surface is provided with buoyant device 2, also comprise support 4, described support 4 is provided with the identical pulley of both direction 5, between described two pulley 5 levels, there is default spacing distance, described pulley is provided with drag rope 3, described drag rope 3 has default length, described drag rope 3 one end connects degasser, the other end and the first balance weight body 6 mount, described first balance weight body weight is less than the weight sum of degasser and buoyant device, also comprise the second balance weight body that several and the first balance weight body vary in weight, the weight of described second balance weight body is greater than respectively and is less than the first balance weight body, when the proportion of drilling fluid changes, buoyancy also can change, the weight of balance weight body can be regulated to be original definite value to keep degasser to absorb water, when drag rope and the second balance weight body mount, described second balance weight body weight is less than the weight sum of degasser and buoyant device.
Described buoyant device is the sealed compartment or the buoyant spheres that are arranged at degasser surface.
A kind of degasser that can keep draft that the utility model proposes, the storehouse of a sealing is added outside degasser body, we allow the total apparent weight m1 of degasser omit > balance weight body m2, at this moment because Action of Gravity Field degasser can move downward, a buoyancy can be produced when there being the out-of-date degasser sealed compartment of drilling liquid flow, as m1+f buoyancy=m2, degasser and balance weight body will balance, when drilling liquid changes, degasser will be automatically found equalization point under the effect of balance weight body and buoyancy, when liquid level fluctuates up and down, degasser will allow the drinking water of degasser substantially keep a definite value with liquid fluctuating.When the proportion of drilling fluid changes, buoyancy also can change, and at this moment we can regulate the weight of pouring weight m2 to be original definite value to keep degasser to absorb water.
The risk that may exist, make cake impact due to drilling fluid and can produce outward mud cake at degassed wall m1 is increased and destruction of balance, this mud cake needing the cleaning of operator on duty timing to produce, also can clear up by adding mud device clearly on the upside of upper degasser.
A kind of degasser that can keep draft of proposition of the present utility model, when drilling liquid changes, degasser will be automatically found equalization point under the effect of balance weight body and buoyancy, when liquid level fluctuates up and down, degasser will allow the drinking water of degasser substantially keep a definite value with liquid fluctuating, thus improves the judgement of degasser to the accuracy of data and oil-gas Layer character.When the proportion of drilling fluid changes, buoyancy also can change, and at this moment we can regulate the weight of balance weight body to be original definite value to keep degasser to absorb water.A kind of degasser that can keep draft of proposition of the present utility model, structure is simple, easy to use, is adapted at promoting on a large scale in compound logging work.
Type also can have other embodiments; when not deviating from the utility model spirit and essence thereof; person of ordinary skill in the field is when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to claim of the present utility model.
