Abstract
The invention provides an x-ray tool for an oilfield fluid. The tool may include a generator portion housing a collimator about a target from which x-rays are emitted. In this manner x-rays may be attenuated right at the target such that a majority of shielding otherwise necessary for safety concerns may be eliminated. Rather, by employing the target within the collimator, shielding of the generator may be limited to a single shielding plate within the generator portion that is positioned parallel to the target at the opposite end of an x-ray tube therebetween. As a result of this configuration, an x-ray tool for analysis of oilfield fluids may be provided with a minimum weight of shielding material. Thus, hand-held user friendly embodiments may be safely employed at the oilfield.
Description
Technical field
The present invention relates to analyze the aid of oilfield fluid.Especially, the present invention relates to compactness and X ray instrument very flexibly.
Background technology
Be usually directed to adopt the various application of oilfield fluid from the field produces hydro carbons.For example, for extract hydro carbons from the oil field, a large amount of main equipments may be transported to the oil field.These application may relate to by the well that pierces the stratum in the oil field adds oilfield fluid to obtain hydro carbons.Then, can hydro carbons be extracted out from well with the oilfield fluid that is added in some cases.
The DRILLING APPLICATION that is used for forming at first well relates to add a kind of application of oil well fluid, wherein drilling mud in drilling process circular flow to and flow out drill bit.The another kind of oilfield fluid is used and can be comprised that the completion application is to give well construction integrality and navigability.This completion is used the cementing that can be included in the well bore casing district in the well, wherein pumps into cement in the well and is squeezed in the well bore casing district and all the other expose between boreholes wall.
Except that mud and cement, also other fluid can be introduced in the well.For example can under high pressure fracturing fluid be introduced in the well, to form the crack of passing the borehole wall and entering the stratum in the production wellblock.Also can from well, reclaim the fracturing fluid of certain percentage subsequently.Similarly, dosage and other application may relate to Xiang Jingzhong interpolation oilfield fluid.
The characteristic of aforesaid oilfield fluid is most important for the effect of the application that utilizes oilfield fluid.Thereby the way of monitoring oilfield fluid character is very general closely in the use.For example, under the situation that pressure break is used, the density the when fracturing fluid of monitoring injection well injects usually.The information of the support dosage that provides in well in the relevant processing procedure can be provided of the fracturing fluid density.Consider that the type of proppant and the formation of measuring for above-mentioned crack are generally key factor, these information may be very important.In fact, in many cases, the owner of well is according to the expense of the support dosage payment fracturing operation that pumps into the down-hole.Thereby the accuracy of described measuring density may be very important.Particularly it is practical with regard to typical pressure break is used the fact that may relate to about 0.5 million pounds～about 2,000,000 pounds of proppants.Thereby, industrially require of the fracturing fluid measuring density to be accurate in 1% usually.
Density when pumping in the well for the precise monitoring fracturing fluid is used various radioactive density meters usually in the oil field.Radioactive density meter connects along the pipeline that leads to from fracturing pump device or house steward the well.Densometer comprises the radioactive source that is positioned at a place on the described pipeline, and for example radiocesium (is generally Cs
137).The opposite side that detector is positioned at described pipeline is used to detect the gamma ray that caesium sends.Outside the exception pipeline material itself, of the fracturing fluid density will determine the testing result that detector is final in the pipeline.Thereby, the effect of drain wire material, the information that the indication of the fracturing fluid density that in-line flows relatively will be provided of the amount of the gamma ray that radioactive source sends and the detected amount of detector.The radioactive density meter of Ying Yonging is accurate to usually and is better than in about 1% by this way.
Disadvantageously, above-mentioned radioactive density meter relates to the on-the-spot dangerous radioactive substance that uses.Densometer must manually be placed and use with manual mode, thereby makes the user stand to be exposed to the great risk of hazard class radiation.In order to eliminate the potential risk of using radioactive substance at operating position, densometer is set to mainly the part of the main equipment made by shielding material usually.Thereby, sacrificed the flexibility of radiation density counter device basically.In addition, also there is the possibility of shield partial failure, even only the inefficacy of minimum degree also can be to the your healthy danger greatly that constitutes in scene.
For solving the harm of using radioactive source, as described in the series application No.11/532236 that is called " Apparatusand Method for Well Services Fluid Evaluation Using X-Rays " that submitted on September 15th, 2006, can adopt the photon generator of X-ray density meter form.By this way, be similar to above-mentioned radioactive density meter, X ray seen through be used for the pipeline that detector detects.Under the situation of X-ray density meter, the intensity of the X ray of being launched still is enough to see through fully pipeline, but this intensity is starkly lower than the gamma ray that radioactive density meter is launched.In addition, when not using, the X-ray density meter can simply cut out, thereby can not stay the huge hidden danger of harmfulness emission.
The above-mentioned advantage of X-ray density meter is very remarkable, particularly considers and has eliminated on-the-spot harmfulness radioactive source fully.Yet can to launch a large amount of densities of infection lower but still have the X ray of potential danger for the X-ray density meter in operating process.Thereby, still need enough shieldings, with near being perfectly safe of user guaranteeing.Thereby the X-ray density meter is still quite inflexible device of 150～250 pounds of weighing.Thereby the assembled on site of this device, location and dismounting are still great challenge for the user.
Summary of the invention
Be provided for measuring the X ray instrument of oilfield fluid character.This X ray instrument can comprise to being connected target on the X-ray tube provides the generator of electron beam, and target is used to receive electron beam and the corresponding X ray that sends.Collimater can be arranged on the collimation that is used for X ray on every side of target.

The specific embodiment
With reference to certain X ray instrument that in the oil field, is used for the pressure break application embodiment is described.Yet other field use also can be utilized the described X ray execution of instrument of the application scheme.For example, cementing and DRILLING APPLICATION can be used the described X ray execution of instrument of the application scheme.Which kind of situation no matter, the included X ray instrument of the described embodiment of the application need be not more than about 25lb or following shield is used safely for the user.In fact, following oil field X ray instrument can have less than the gross weight of about 50lb and have configuration flexibly, is used in user friendly ground, oil field hand-held and placement.
Refer now to Fig. 1, show the oil field X ray execution of instrument scheme 100 that is connected on the oilfield fluid pipeline 150.Oilfield fluid pipeline 150 is set, in the well 310 in oil field 301 shown in Figure 3, to carry oilfield fluid 160.Especially, embodiment shown in discloses the oilfield fluid 160 of the fracturing fluid form that is used for the pressure break application.Provide support the high pressure pressure break of agent 165 by fluid 160 with auxiliary stratum.Yet, in other embodiments, can use the oilfield fluid and the application of other type, comprise the drilling mud and other suitable fluid and the application that are used for cemented cement paste or are used for drilling well.
The oil field X ray instrument 100 of Fig. 1 is set, to help to determine the information of oilfield fluid 160 character in the relevant pipeline 150.This information can relate to density, solid content, and solid phase, liquid and gas character or physical state character, material are formed or other character.In addition, even integrated unnecessary X ray shield, instrument 100 still can be gross weight less than about 50lb and preferably less than the equipment of the hand-held of about 30lb, manual positioning, easy operating.
In conjunction with reference to figure 2, show oil field X ray instrument 100 with generator part 125, this generator part 125 is connected on the detector portion 175 by anchor clamps or the big envelope 110 around the oilfield fluid pipeline 150.The size of ruling big envelope 110 is so that the testing agency 177 of detector portion 175 is aimed in the outlet 135 of generator part 125.In one embodiment, testing agency 177 has the scitillating material that joins with the interface with photocathode and electron multiplier, detects to realize indication.Further describe as the application, the X ray 250 that generator part 125 is sent can pass fluid line 150, is impaired to a certain degree by oilfield fluid 160, and detected then mechanism 177 is detected.By this way, but the identification oilfield fluid to the weakening of X ray 250 so that relevant information of being passed through oilfield fluid 160 character to be provided.In one embodiment, the low-intensity scattered x-ray that can collimate and to pass oilfield fluid 160 once in a while indirectly testing agency 177 to avoid detecting.This X ray may be harmless, but does not have informedness substantially, or even potential obstacle effective and accurately definite oilfield fluid characteristic.
Shown in fluid line 150 can be wall thickness and be nominally 15000lb or above steel pipe for about 0.5 inch.Thereby X ray instrument 100 can have the high energy that produces X ray 250 between about 450kV at about 100kV and dispose, with fluid line 150 shown in passing effectively.Yet this still is starkly lower than the intensity of above-mentioned radioactive source, the shield 145 that still can be provided with to a certain degree as described below.
Still in conjunction with Fig. 2 with reference to figure 1, generator part 125 is set, guiding electron beam 200 into target 101, thereby produce the X ray 250 that passes fluid line 150 as mentioned above.In the illustrated embodiment, generator part 125 can comprise conventional filament 137 feeding electric current by conventional methods, thereby discharges electronics.Filament 137 can be connected on the X-ray tube that nickel or other suitable material make or be arranged in the described X-ray tube, so that electronics is with the form directive target 101 of electron beam 200.Target 101 can be made and be had enough thickness and keep off electron beam 200 to cut by gold, copper or other suitable material.Yet, in this process, the x-ray photon of target 101 emission X ray forms (for example 250).
As mentioned above, shield 145 is separated by by pillar 139 and filament 137 and X-ray tube 130.In one embodiment, spacing distance can be about 2～5 inches.In the end of the X-ray tube 130 that has filament 137 as shown in the figure is under high voltage and the unearthed situation, may need described interval.Yet, by making the X-ray tube 130 end ground connection relative, can directly be close to and closely place collimaters 131, and collimater 131 has limited size around X-ray tube 130 with filament 137, the following collimator effect that further describes is provided simultaneously.
Now continue with reference to figure 1 and Fig. 2, describe the structure of generator part 125 in detail.Particularly, the embodiment of generator part 125 is described, wherein make X ray instrument 100 be used safely in manually to place effectively and use desired shield gross weight obviously to reduce (for example being reduced to the weight of shield 145).In fact, as mentioned above, based on the structure shown in Fig. 1 and Fig. 2, the weight of entire tool 100 can be not more than about 30lb.
In the embodiment of Fig. 1 and Fig. 2, collimater 131 is arranged on around the target 101.Promptly target 101 is not clipped between X-ray tube 130 and the adjacent collimator 131, but with target 101 actual being arranged in the collimater 131.By this way, the X ray 250,251,275,276 that target 101 is produced directly collimates, so that the actual amount of leaving collimater 131 zones is substantially limited in the particular range that the shunt X ray 250,251 that is limited as angle α and α ' arrives target 101 either sides.Form those X ray that drop on outside angle α and the α ' scope by X ray 275,276.Describedly also avoid it to leave collimater 131 zones substantially by X ray 275,276 direct conductively-closeds.Except that above-mentioned X ray 250,251,275,276, a small amount of low-intensity X ray (not shown) can near scattering generator part 125 inside.Yet rigid casing 127 can be made by conventional stainless steel, thereby has got rid of the possibility that this low-intensity X ray leaves generator part 125 and the user constituted harm basically.Should be noted in the discussion above that this sleeve pipe with prior art is opposite, promptly X-ray tube, target and collimater structure arranged in a straight line requires whole sleeve pipe to be made by shielding material in the prior art.
Because above-mentioned collimater 131 and target 101 structures, X ray instrument 100 is used safely in manually to use the amount of desired shield obviously to reduce.In fact, suppose to fail to leave collimater 131 zones, with regard to shielding, only pay close attention to X ray 250,251 along separate routes by the X ray 275,276 that ends outside angle α and α ' that target 101 penetrates.Yet angle is that the shunt X ray 250 of α is intended to leave generator part 125 and advance to detector portion 175 as mentioned above, weakens naturally thereby follow inbound path.Thereby the X ray shielding potential safety hazard of only depositing is that relative angle is the shunt X ray 251 of α ' those X ray (for example towards filament 137) back to above-mentioned electron beam 200 sources.
Angle is that the shunt X ray 251 of α ' can fully be shielded by the shield 145 that is parallel to target 101, so that shunt X ray 251 is still between target 101 and shield 145.Thereby, the minimum dimension of shield can with angle [alpha] ' and target 101 and shield 145 between distance directly related.For example, in the illustrated embodiment, shield 145 is separated by with target 101 by X-ray tube 130, filament 137 and pillar 139.Thereby the size of these parts can determine that cut-off angles is the size of the required shield 145 of all X ray 251 of α '.Yet,, can obviously reduce the weight and/or the size of X ray instrument 100 by shield 145 shown in whole shield is restricted to.
With reference to said structure, in one embodiment, the weight of shield 145 can be less than about 25lb, and the weight of whole X ray instrument 100 is not more than about 50lb.As a comparison, otherwise the shield of whole X ray instrument 100 can make tool and 100 surpass about 150lb.Perhaps, said structure makes X ray instrument 100 can have the flexibility, hand-holdable of improvement, thereby than large-scale X-ray equipment easy operating more, described large-scale X-ray equipment does not adopt the target 101 that places in the collimater 131, thereby for the obvious shield of purpose of safety needs, even may be greater than the shield of 100lb greater than 50lb.
Continuation is with reference to figure 2, and simultaneously with reference to figure 1, view 2-2 shows the amplifier section of X ray instrument 100.In this view, the end of X-ray tube 130 is in the collimater 131 of contiguous target 101.Collimater 131 is used to carry out described collimation around the end of X-ray tube 130 and target 101.In fact, suppose that collimater 131 and target 101 can be made by identical materials, in one embodiment, in fact collimater 131 and target 101 have single or overall structure.
Illustrate electron beam 200 to leave the end of X-ray tube 130 shown in Figure 2 and clashed into target 101, made a large amount of X ray 250,251,275,276 from target, penetrate.X ray 250,251,275,276 can weaken by collimated device 131, if it is interior then cast out from collimater 131 perhaps to drop on above-mentioned proper angle α, α '.Can angle [alpha], α ' be set according to the size and target 101 location therein of collimater 131.For example, in one embodiment, target 101 places near collimater 131 mid points, angle [alpha], α ' is equated substantially and very narrow, according to the length of collimater 131 between about 1 °～about 10 °.Yet, in other embodiments, can adopt other angle [alpha], α ' scope, so that X ray 250,251 penetrates along separate routes from collimater 131.
Leave collimater 131 directive fluid lines 150 shunt X ray 250 can by shown in the outlet that reduces of structural thickness 135 penetrate.Yet identical X ray 250 also can reach reference detector 134, and to read the X ray 250 that passes through before the fluid line 150, the X ray testing result that is used for obtaining with testing agency 177 after X ray passes fluid line 150 is compared.In one embodiment, the real-time feedback mechanism of processor can utilize the reading of reference detector 134 to adjust the X ray output of instrument 100.In another embodiment, processor can be compared the reading of analyzing reference detector 134 and testing agency 177.In addition, the out of Memory about the data of known chemical material and relative fluid 160 that may type can be stored in the processor.By this way, can set up the benchmark of X ray information, to determine the X ray attenuation degree in the fluid line 150.Thereby, can obtain the more accurate density or the out of Memory of relevant oilfield fluid 160.
In alternate embodiment, as shown in Figure 4, strainer 409 can be placed on before the reference detector 134,434 decay that takes place with in analog stream fluid line 150 self material.For example, detected X ray 250 passes 1 inch thick fluid line 150 pipe wall material before detected mechanism 177 is detected, strainer 409 can by about 1 inch thick and make with fluid line 150 material identical materials.By this way, the reference line (see figure 4) that can obtain raising as described below by reference detector 134,434.Which kind of situation no matter, detector shield 136 is connected in reference detector 134 and the testing agency 177 so that residual arbitrarily X ray 250 decay.
