Description
본 발명은 오일샌드 혹은 타르샌드에 함유된 초중질유 및 중질유와 같은 오일성분의 함유량을 예측하는 방법에 관한 것이다.The present invention relates to a method for predicting the content of oil components such as super heavy oil and heavy oil contained in an oil sand or tar sand.
세계적으로 근대화와 산업화의 영향에 따라 이에 사용되는 에너지의 문제는 가장 중요한 문제로 대두되고 있다. 특히, 근래의 유가상승으로 인해 기존의 석유자원이 아닌 좀 더 풍부하고 값싼 에너지원의 중요성이 부각되고 있다. 이에 오일샌드에 대한 관심이 증대하고 있는 상황이다.Due to the influence of modernization and industrialization around the world, the energy problem used is emerging as the most important problem. In particular, the recent rise in oil prices has highlighted the importance of more abundant and cheaper energy sources rather than existing oil resources. Thus, interest in oil sands is increasing.
오일샌드는 통상적으로 모래에 약 10 ~ 20 중량%의 초중질유의 일종인 비투멘(bitumen)을 함유하고 있는 천연물질이며, 통상적으로 모래를 제거하고 비투멘 성분만을 추출하여 업그레이드하면 유용한 자원인 합성석유(Synthetic Crude Oil; SCO)를 얻을 수 있다. 이러한 오일샌드는 매장량이 풍부하여 이와 관련된 기술 및 광구 확보를 통하여 저렴한 가격의 원료 공급과 안정적인 원유 공급을 가능하게 할 수 있게 한다. 오일샌드와 관련된 기술은 캐나다가 가장 앞선 기술을 보유하고 있고, 캐나다 알버타(Canada alberta)주에 대부분 그 시설이 집중되어 있다.Oil sand is a natural material that contains bitumen, a kind of ultra heavy oil, which is usually in sand, and is a synthetic material that is a useful resource for upgrading by removing sand and extracting only bitumen components. Synthetic Crude Oil (SCO) can be obtained. These oil sands are rich in reserves, which enables the supply of raw materials at a low cost and stable supply of crude oil through securing related technologies and mines. The technology related to oil sands is Canada's most advanced technology, and most of its facilities are concentrated in the province of Canada alberta.
현재 오일샌드를 추출하는 방식으로는 노천채굴(Mining), SAGD(Steam Assisted Gravity Drainage), CSS(Cyclic Steam Stimulation) 등이 있으나, 이러한 오일샌드에서 오일성분의 함유량을 예측을 통하여 경제성 분석을 실시하고 이를 통해 채굴 및 개발 여부를 결정해야 한다.Currently, oil sands are extracted by mining, steam assisted drainage (SAGD), and cyclic steam stimulation (CSS) .However, the oil sands in these oil sands are analyzed for economic efficiency through prediction of oil content. This should determine whether to mine and develop.
오일샌드의 오일성분의 함유량의 예측하기 위해서는 뜨거운 물에 오일샌드를 넣고 이를 기계적으로 분리하는 방법(CHWE; Clock Hot Water Extraction), ASTM 95, 96, 473, 1796, 4072, 4807 등에서 제시된 바와 같이 물의 함량 및 용매 등에 녹아나는 오일성분을 결정하는 방법 등이 제시되어 있다. 그러나 이들 방법은 장치가 복잡하고 처리시간이 오래 걸리는 단점이 있다.To predict the oil content of an oil sand, the water sand is added to the hot water, as shown in CHWE (Clock Hot Water Extraction), ASTM 95, 96, 473, 1796, 4072, 4807, etc. A method of determining the oil component dissolved in the content and solvent, and the like are provided. However, these methods have the disadvantage that the apparatus is complicated and the processing time is long.
또한, 근적외선 반사 모드(Near-IR reflectance mode)를 이용하고 이를 광학프로브(optical probe)에 연결하여 오일샌드 내에 함유된 비투멘 성분의 특정 반사 강도를 측정하는 방법이 상용화되어 적용되고 있다. 그러나 상기 방법은 고가의 장비가 요구되며, 샘플의 표면상태에 따라 산란정도가 바뀌게 되어 측정에 문제점이 발생할 수 있다. 샘플의 표면에 근적외선을 직접적으로 가하여 이에서 흡수되고 반사되는 빛의 강도를 측정하므로 근적외선이 흡수되는 길이(penetration length)사 샘플마다 달라질 수 있다는 문제점을 갖는다(참조: 1) Kelley, US Patent 1961, 2,980,600., 2) Friesen W. I., Qualitative analysis of oil sand slurries using on-line NIR spectroscopy. Applied Spectroscopy 1996;50;1535-1540. 3) Shaw R. C., Kratochvil B., Near-IR diffues reflectance analysis of Athabasca oil sand. Anal. Chem. 1990;62;167-174).In addition, a method of measuring a specific reflection intensity of the bitumen component contained in the oil sand by using a near-infrared reflection mode and connecting it to an optical probe has been commercially applied. However, the method requires expensive equipment, and the scattering degree is changed according to the surface state of the sample, which may cause a problem in the measurement. Since near-infrared rays are directly applied to the surface of the sample to measure the intensity of light absorbed and reflected therefrom, it has a problem that the near-infrared rays may vary from sample to sample (penetration length) (see: 1) Kelley, US Patent 1961 2,980,600., 2) Friesen WI, Qualitative analysis of oil sand slurries using on-line NIR spectroscopy. Applied Spectroscopy 1996; 50; 1535-1540. 3) Shaw R. C., Kratochvil B., Near-IR diffues reflectance analysis of Athabasca oil sand. Anal. Chem. 1990; 62; 167-174).
본 발명은 오일샌드의 오일성분을 예측하기 위한 방법에 관한 것으로, 기존의 예측방법이 갖는 고비용, 장기처리시간 및 부정확성의 문제점을 해결하는 것을 목적으로 한다. The present invention relates to a method for estimating oil components of an oil sand, and aims at solving the problems of high cost, long processing time and inaccuracy of a conventional prediction method.
본 발명은 상기 목적을 달성하기 위하여 지질학적으로 특성이 유사한 지역의 오일샌드의 오일성분 및 비오일성분을 적외선분광분석하여 검정곡선을 얻어내고, 측정대상인 오일샌드를 적외선분광분석하고 상기 검정곡선과 대비하여 오일성분 함량을 예측하는 방법에 관한 것이다.In order to achieve the above object, the present invention obtains a calibration curve by infrared spectroscopy analysis of oil components and non-oil components of oil sands having similar geological characteristics, and infrared spectroscopy analysis of the oil sands to be measured. It relates to a method of predicting the oil content in contrast.
본 발명은 기존의 근적외선 반사를 이용한 방법에 비하여 더 간단하고 정확한 방법으로 오일성분(초중질유 및 중질유)의 함유량을 예측하는 방법을 제공하고, 노천채굴 및 지하 오일샌드 층 탐사에 있어서, 오일성분을 함유량에 따른 경제성을 분석하기 용이한 방법을 제시하는 효과가 있다. The present invention provides a method for predicting the content of oil components (ultra heavy oil and heavy oil) in a simpler and more accurate manner than the conventional method using near infrared reflection, and in the open pit and underground oil sand layer exploration, There is an effect of suggesting an easy way to analyze the economics of the content.
본 발명은 오일샌드의 오일성분과 비오일성분의 함량에 대한 적외선분광분석(FT-IR)에 따른 검정곡선을 작성하는 1단계; 및 측정대상인 오일샌드를 적외선분광분석하여 상기 작성한 검정곡선과 대비하는 단계를 포함하는 오일샌드의 오일성분 함량 측정방법에 관한 것이다.The present invention comprises the steps of preparing a calibration curve according to infrared spectroscopic analysis (FT-IR) for the content of oil and non-oil components of the oil sand; And it relates to a method for measuring the oil content of the oil sand comprising the step of contrasting the calibration curve prepared by infrared spectroscopic analysis of the oil sand to be measured.
바람직하게는 본 발명은 상기 검정곡선은 오일성분과 비오일성분의 특성 주파수의 피크를 기준으로 하는 것을 특징으로 하는 오일샌드의 오일성분 함량 측정방법에 대한 것이다.Preferably, the present invention relates to a method for measuring the oil content of an oil sand, characterized in that the calibration curve is based on peaks of characteristic frequencies of the oil component and the non-oil component.
또한 바람직하게는 본 발명은 상기 검정곡선은 오일성분 및 비오일성분의 흡수도비에 따른 농도비의 선형적 관계인 것을 특징으로 하는 오일샌드의 오일성분 함량 측정방법에 대한 것이다.In addition, the present invention preferably relates to a method for measuring the oil content of the oil sand, characterized in that the calibration curve is a linear relationship of the concentration ratio according to the absorption ratio of the oil component and the non-oil component.
본 발명은 기존의 오일성분 예측방법의 문제점을 해결하기 위해, 널리 사용되는 적외선분광분석(FT-IR)을 이용하고, 흡수길이가 달라지는 문제점을 해결하기 위해 탐사하고자 하는 지역의 모래와 오일성분과의 함량비가 조절된 복합체를 형성하여 사용하고 이를 적외선분광분석하여 검정곡선(calibration curve)을 얻어내어, 오일샌드의 샘플의 적외선분광분석하여 얻어진 결과를 검정곡선과 대비하여 오일함량을 예측하는 방법에 대한 것으로, 기존의 방법보다 정확한 함유량을 예측하도록 하는 방법을 제공한다.The present invention uses a widely used infrared spectroscopy (FT-IR) to solve the problems of the conventional oil component prediction method, and sand and oil components of the region to be explored to solve the problem of the absorption length is different; In the method of forming a composite having a controlled content ratio of, and using an infrared spectroscopic analysis to obtain a calibration curve, the result obtained by infrared spectroscopic analysis of the sample of the oil sand is compared with the calibration curve. In this regard, the present invention provides a method for predicting more accurate content than conventional methods.
오일샌드는 오일성분의 대부분은 비투멘(bitumen)이다. 비투멘은 석탄과 가스 상태에 있는 것들을 제외한 수소와 탄소로 이루어진 천연 화합물을 말하는 것으로, 오일샌드에 함유된 비투멘 성분을 추출하여 업그레이드하여 합성석유를 얻을 수 있다.Oil sands are mostly bitumen. Bitumen refers to a natural compound composed of hydrogen and carbon, except those in the coal and gas phase, and can be upgraded by extracting and upgrading the bitumen contained in the oil sand.
오일성분인 비투멘의 적외선분광분석의 특징적인 피크는 3000 cm-1에서 나타나게 되고, 모래성분에 특징적인 피크는 1000 cm-1에서 나타난다.The characteristic peaks of infrared spectroscopy of oil-based bitumen appear at 3000 cm -1 and the characteristic peaks of sand appear at 1000 cm -1 .
오일성분인 비투멘의 특징적인 피크는 C-H 비대칭 스트레칭(C-H asymmetrical stretching)에 관련되어 있으며, 탄화수소계의 피크이다. 이러한 피크에서 Ibitu(0)와 Ibitu를 얻게 된다.The characteristic peak of the oil-based bitumen is related to CH asymmetrical stretching and is a hydrocarbon-based peak. At these peaks I bitu (0) and I bitu are obtained.
모래성분의 특징적인 피크는 Si-O-Si의 반대대칭 미폴딩 진동(antisymmetric unfolded vibration of Si-O-Si)에 관련된 것으로, 이는 실리카를 함유하는 모래성분에서는 공통적으로 나타난다. 이러한 피크에서 Isand(0)와 Isand를 얻게 된다(참조: Jiang T, Zhao Q, Yin H, Synthesis of highly stablized mesoporous sieves using natural clay as raw material. Appl. Clay Sci. 2007;35:155-161).The characteristic peak of the sand component is related to the antisymmetric unfolded vibration of Si-O-Si, which is common in silica-containing sand components. At these peaks, we obtain I sand (0) and I sand (see Jiang T, Zhao Q, Yin H, Synthesis of highly stablized mesoporous sieves using natural clay as raw material.Appl. Clay Sci. 2007; 35: 155- 161).
이렇게 얻어진 피크 강도는 다음의 식에서 이용된다.The peak intensity thus obtained is used in the following equation.
위와 같은 Beer-Lambert 법칙에서 흡수도(Absorbance; A)는 흡수계수(a), 성분의 농도(c), 빛이 통과하는 길이(l) 값에 비례하여 나타나게 된다. 적외선분광분석 실험시 오일샌드 안에는 같은 l 값을 가지므로 위의 식을 정리하면,Absorption (A) in the Beer-Lambert law is shown in proportion to the absorption coefficient ( a ), the concentration of the component ( c ), the length of the light passing ( l ). In the infrared spectroscopy experiment, the oil sand has the same l value.
로 정리가 가능하다.It is possible to organize.
다음의 과정을 거쳐서 식(3)과 같은 검정곡선을 얻을 수 있다.Through the following process, we can obtain the calibration curve as shown in Equation (3).
① 함유량을 예측하고자 하는 지역의 모래성분과 오일성분을 입수한다. 모래성분 및 오일성분의 시료에 대하여 적외선분광분석 실험을 수행하고, 각 성분의 특징적인 FT-IR 피크를 찾는다. 일반적으로 모래성분은 1000 cm-1, 오일성분은 3000 cm-1 부근에서 나타난다.① Obtain the sand and oil components of the area where you want to predict the content. Infrared spectroscopy experiments are performed on sand and oil samples and find characteristic FT-IR peaks for each component. In general, the sand component is around 1000 cm -1 and the oil component is around 3000 cm -1 .
② 함량비를 조절하여 오일성분과 모래성분의 복합체를 형성한다. 효과적인 복합체의 형성을 위해서는 오일성분의 점도를 낮출 수 있는 용매(펜탄, THF, 아세톤, 벤젠 등)을 사용하여 오일성분을 분산시킨 후 이를 모래성분과 함께 충분히 섞어주고 용매를 증발시켜 균일하게 분산된 복합체를 형성한다.② Adjust the content ratio to form a complex of oil and sand components. In order to form an effective complex, the oil components are dispersed using a solvent (pentane, THF, acetone, benzene, etc.) that can lower the viscosity of the oil component, and then mixed with the sand component sufficiently, and the solvent is evaporated to uniformly disperse the oil component. To form a complex.
③ 상기 제조한 오일성분의 함유량이 조절된 복합체를 이용하여 적외선분광분석에 따른 측정을 실시한다. 이러한 측정을 통하여 상기 수학식 1-3에서 필요로 하는 피크의 강도를 얻게 된다.③ The composite according to the content of the prepared oil component is measured by infrared spectroscopy analysis. Through this measurement, the intensity of the peak required by Equation 1-3 can be obtained.
④ 상기 수학식 3에서 검정곡선을 얻기 위하여 모래성분/오일성분의 농도비와 모래성분/오일성분 적외선분광분석 피크와의 관련값을 얻어내고 이로부터 최소자승법(least square)을 이용하여 직선식을 얻어낸다. 이 직선식은 y절편이 0 값에 가까이 위치해야 하고 선형도(R)이 1에 가까이 있을수록 좋은 결과라 할 수 있다. ④ In order to obtain the calibration curve in Equation 3, the value of the concentration ratio of the sand component / oil component and the infrared component of the sand component / oil component is obtained, and a linear equation is obtained from the least square method.
