Description

原油浮筒称重计量装置 Crude oil buoy weighing and measuring device

技术领域 technical field

本实用新型属于石油工业的原油计量设施,特别是原油浮筒称重计量装置,在单井现场量油使用,使原油计量准确,操作简单。The utility model belongs to crude oil metering facilities in the petroleum industry, in particular to a weighing and metering device for a crude oil buoy, which is used for measuring oil on the spot of a single well, so that the metering of crude oil is accurate and the operation is simple.

背景技术 Background technique

目前,在石油工业的单井现场量油多使用计量罐体积法量油,最大的缺点是误差大。分析主要原因是计量罐内原油含气垂向分布不均匀,无法计量出完全脱气后的原油体积。如改测原油重量,可有效避免原油中的含气影响,目前质量法量油技术主要有过磅计量、玻璃管量油和压力传感系统量油。过磅量油费时、费力,成本高,控制程序繁琐、及时性差。玻璃管量油必须保证始终有底水,且底水不被侵染,否则计量不准,而到了冬季,玻璃管容易结冰、冻坏无法使用。压力传感系统量油成本较高,对高粘油适应性差,且不耐用,不适合推广。At present, the measuring tank volume method is often used to measure oil in the field of single well in the petroleum industry, and the biggest disadvantage is that the error is large. The main reason for the analysis is that the vertical distribution of gas in the crude oil in the metering tank is uneven, and the volume of crude oil after complete degassing cannot be measured. If the weight of crude oil is changed, it can effectively avoid the influence of gas in crude oil. At present, the mass method oil measurement technology mainly includes weighing measurement, glass tube oil measurement and pressure sensor system oil measurement. It is time-consuming, laborious and costly to measure oil by weighing, and the control procedure is cumbersome and poor in timeliness. The glass tube to measure oil must ensure that there is always bottom water, and the bottom water is not contaminated, otherwise the measurement will be inaccurate, and in winter, the glass tube is easy to freeze, freezes and cannot be used. The pressure sensing system has a high cost of oil measurement, poor adaptability to high-viscosity oil, and is not durable, so it is not suitable for promotion.

发明内容 Contents of the invention

本实用新型的目的是提供原油浮筒称重计量装置,减少含气原油的计量误差,使用称重法量油,提高计量的精确度。The purpose of the utility model is to provide a weighing and measuring device for crude oil buoys, reduce the measurement error of gas-containing crude oil, use the weighing method to measure oil, and improve the accuracy of measurement.

使用本技术解决方案可达上述目的:原油浮筒称重计量装置包括浮筒、游梁和称重砣,游梁上设有游码,浮筒由联接铰链固定在游梁的一端,游梁的另一端悬挂称重砣,平衡支轴固定在罐体的体壁上,支撑着游梁。The above-mentioned purpose can be achieved by using this technical solution: the crude oil buoy weighing and measuring device includes a buoy, a swimming beam and a weighing weight. The weight is suspended, and the balance shaft is fixed on the body wall of the tank to support the beam.

本实用新型与现有技术相比具有以下有益的效果:本实用新型根据阿基米得原理完成对原油或其他液体的称重法计量。按照阿基米得原理“物体所受的浮力等于物体排开液体的重量”设计本装置。通过调整游码和称重砣的重量,使游梁平衡,实现对浮筒所受到的浮力的测量。由于浮筒为柱形的,不同高度处的截面积恒定,因此所受的浮力与浮筒底面受到的液体压力成线性关系。这样被测计量罐罐底受到的液柱压力,可通过游码在游梁上的标尺位置以及称重砣上砝码的重量标定值反应出来,通过计算可得出准确的计量结果。本实用新型较现有的计量方法和计量工具,计量准确,结构简单,易于加工制作,经济耐用。不受计量罐内温度、光线和季节的影响。浮筒被封闭安装在计量罐内,从而有效避免H2S中毒和原油被盗的现象,易于推广。使用本装置进行原油计量不需要在被计量的计量罐上另装连通管道。被测介质适应范围广,不论是均匀液体,还是非均匀液体,甚至含气的粘度较大的原油,只要有一定的流动性的液体都可使用。Compared with the prior art, the utility model has the following beneficial effects: the utility model completes the weighing measurement of crude oil or other liquids according to the principle of Archimedes. The device is designed according to the principle of Archimedes that "the buoyancy force on an object is equal to the weight of the liquid displaced by the object". By adjusting the weight of the swimming code and the weighing weight, the traveling beam is balanced to realize the measurement of the buoyancy on the buoy. Since the buoy is cylindrical, the cross-sectional area at different heights is constant, so the buoyancy is in a linear relationship with the liquid pressure on the bottom of the buoy. In this way, the liquid column pressure on the bottom of the measured measuring tank can be reflected by the position of the scale on the swimming beam and the calibration value of the weight on the weighing mound, and accurate measurement results can be obtained through calculation. Compared with the existing measurement methods and measurement tools, the utility model has the advantages of accurate measurement, simple structure, easy processing and manufacture, economical and durable. Not affected by temperature, light and season in the metering tank. The buoy is sealed and installed in the metering tank, thereby effectively avoiding H 2 S poisoning and crude oil theft, and is easy to popularize. The use of this device for crude oil metering does not require additional communication pipes to be installed on the metering tank to be metered. The medium to be tested has a wide range of applications, whether it is a uniform liquid or a non-uniform liquid, or even a gas-containing crude oil with a high viscosity, as long as it has a certain fluidity, it can be used.

具体实施方式 Detailed ways

以下结合实施例对本实用新型做进一步的详述:参见附图1和附图2,原油浮筒称重计量装置包括浮筒1、游梁4、称重砣6,当用于计量粘度较大液体时,为了计量准确、快速,浮筒1外表面应附特氟龙等不粘涂层,当然也可以不附不粘涂层。游梁4上设有游码5,浮筒1与游梁4联接铰链2固定在游梁4的一端,游梁4的另一端悬挂称重砣6,平衡支轴7固定在罐体8的体壁上,固定在顶部或侧面均可,支撑着游梁4,并与游梁4成铰链连接。附图1为将本实用新型通过平衡支轴7固定在罐体8体壁的顶部位置,附图2为固定在罐体8的侧面体壁上,固定在罐体8的侧面体壁上时,需要对罐体8上平衡支轴7的穿出位置,做密封处理。游梁4上还设有水平仪3和标尺,标尺上设有重量刻度。称重砣6包括砣托和砝码,砝码插装在砣托上,可根据测量的实际需要增加或减少砝码的数量。浮筒1为钢性体,有足够的重量,使其在被测液体中不会漂浮,也就是使重量大于可能受到的最大浮力,使浮筒1始终处于垂直的工作状态。安装本装置时,将浮筒1安装在罐体8中离进液口较远、液体较为静止的位置。根据浮筒1的高度对应计算和制做游梁4上标尺的重量刻度。重量刻度的标定可按照计量罐内单位水柱高度对应的水重量进行标定或者按照计量罐内单位水柱高度进行标定。浮筒1单位吃水深度,对浮筒1产生浮力的影响,应当与游码5在游梁4标尺上的单位位移量对应,即浮筒1与游码5存在力矩平衡关系。称重砣6的重量选择应确保增减砝码时对游梁4产生的力矩变化,等于游码5从游梁4标尺的0刻度端移至最大量程刻度时,产生的力矩变化。Below in conjunction with embodiment the utility model is further described in detail: referring to accompanying drawing 1 and accompanying drawing 2, crude oil buoy weighing metering device comprises buoy 1, beam 4, weighing weight 6, when being used for metering the bigger liquid of viscosity , in order to measure accurately and quickly, non-stick coatings such as Teflon should be attached to the outer surface of buoy 1, and of course non-stick coatings can also be attached. The swimming beam 4 is provided with a swimming code 5, the buoy 1 and the swimming beam 4 are connected and the hinge 2 is fixed on one end of the swimming beam 4, the other end of the swimming beam 4 is hung with a weight 6, and the balance shaft 7 is fixed on the body of the tank body 8. On the wall, it can be fixed on the top or the side, supports the beam 4, and is hingedly connected with the beam 4. Accompanying drawing 1 is that the utility model is fixed on the top position of tank body 8 body wall by balance fulcrum 7, and accompanying drawing 2 is fixed on the side body wall of tank body 8, when being fixed on the side body wall of tank body 8 , it is necessary to seal the position where the balance fulcrum 7 passes through the tank body 8 . Also be provided with spirit level 3 and scale on the beam 4, scale is provided with weight scale. Weighing weight 6 comprises weight holder and weight, and weight is inserted on the weight holder, can increase or decrease the quantity of weight according to the actual needs of measurement. The buoy 1 is a rigid body with sufficient weight so that it will not float in the liquid to be tested, that is, the weight is greater than the maximum possible buoyancy, so that the buoy 1 is always in a vertical working state. When installing the device, the buoy 1 is installed in the tank body 8 at a position far away from the liquid inlet and where the liquid is relatively still. Correspondingly calculate and make the weight scale of scale on the beam 4 according to the height of buoy 1. The calibration of the weight scale can be performed according to the water weight corresponding to the unit water column height in the metering tank or according to the unit water column height in the metering tank. The unit draft of the buoy 1 has an influence on the buoyancy of the buoy 1, which should correspond to the unit displacement of the floating code 5 on the scale of the beam 4, that is, there is a moment balance relationship between the buoy 1 and the floating code 5. The weight selection of the weighing weight 6 should ensure that the moment change produced to the beam 4 when increasing or decreasing the weight is equal to the torque change produced when the weight 5 moves from the 0 scale end of the beam 4 scale to the maximum range scale.

根据被测计量罐的大小,可以制造不同称重重量的本计量装置,使每套计量装置都配备相应数量的砝码,每个砝码上都标有标识重量。实际使用时,根据被测计量罐的大小,取一套相应重量的本计量装置安装在计量罐罐体8的体壁上。油井的产出液进入罐体8后,浮筒1被浮起,这时逐步减去称重砣6上砝码个数并调整游码5在游梁4上的位置,使游梁4处于平衡状态。通过水平仪3判断游梁4是否平衡,将称重砣6上减去的砝码个数的标识重量和游码5在标尺上的重量刻度相加,即是罐体8内液体的实际重量。According to the size of the measured measuring tank, the measuring device with different weighing weights can be manufactured, so that each measuring device is equipped with a corresponding number of weights, and each weight is marked with a marked weight. During actual use, according to the size of the metering tank to be measured, a set of this metering device with a corresponding weight is installed on the body wall of the metering tank body 8 . After the output fluid of the oil well enters the tank body 8, the buoy 1 is floated. At this time, the number of weights on the weighing mound 6 is gradually subtracted and the position of the swimming weight 5 on the beam 4 is adjusted to make the beam 4 in balance. state. Judging whether the beam 4 is balanced by the level 3, adding the marked weight of the number of weights subtracted from the weighing weight 6 and the weight scale of the swimming code 5 on the scale is the actual weight of the liquid in the tank body 8.
