Description
技术领域technical field
本发明服务于油水分离领域，尤其是用于需要高效分离的陆上油田和海洋平台管道式油气水分离系统中的油水两相流型转换装置。The invention serves the field of oil-water separation, especially the oil-water two-phase flow type conversion device used in pipeline oil-gas-water separation systems on land oil fields and offshore platforms that require high-efficiency separation.
背景技术Background technique
在石油开采中，油水分离的效率与油相粒径的大小息息相关，提高油相的平均粒径，甚至将油相变为大块状或者连续相能可大大缩短油水分离所需的时间。而在油水两相从井底流至地面时的过程中，会经过阀门、弯头和泵等设备，高度湍流的流场会造成油相破碎成微米量级的油滴甚至乳化问题。这种油滴破碎成细小油滴的现象和乳化等问题，在当油水两相的产量、含油率变化时，会造成油水两相在进入分离器后分离耗时长、效率低的现象。因此，如果在油水分离器之前进行油水两相流型转换，则可以提高后期的油水分离效率。In oil production, the efficiency of oil-water separation is closely related to the particle size of the oil phase. Increasing the average particle size of the oil phase, or even changing the oil phase into a large block or continuous phase can greatly shorten the time required for oil-water separation. When the oil-water two-phase flows from the bottom of the well to the surface, it will pass through valves, elbows, pumps and other equipment. The highly turbulent flow field will cause the oil phase to break into micron-scale oil droplets or even emulsify. This phenomenon of breaking oil droplets into fine oil droplets and emulsification will cause long time-consuming and low efficiency for the separation of oil-water two-phase after entering the separator when the output and oil content of the oil-water two-phase change. Therefore, if the oil-water two-phase flow pattern conversion is performed before the oil-water separator, the efficiency of oil-water separation in the later stage can be improved.

如图1所示，本发明一个实施方式的油水两相流型转换装置一般性地包括依次相连的进液管10、转换管20和出口管30。As shown in FIG. 1 , an oil-water two-phase flow conversion device according to an embodiment of the present invention generally includes a liquid inlet pipe 10 , a conversion pipe 20 and an outlet pipe 30 connected in sequence.
该进液管10在管壁上垂直安装有与内部相通的进药管11，在进药管11下游的内部设置有强化药剂扩散效果的扩散片12。该转换管20用于实现油水中小微粒油聚并成较大的颗粒，内部依次设置有倾斜的整流片21和水平的聚并片22。该出口管30用于将聚并处理后的流体排出至后续油水分离系统。The liquid inlet pipe 10 is vertically installed with a medicine inlet pipe 11 communicating with the inside on the pipe wall, and a diffusion sheet 12 for strengthening the drug diffusion effect is arranged inside the medicine inlet pipe 11 downstream. The conversion pipe 20 is used to coalesce small particles in oil and water into larger particles, and an inclined rectifying piece 21 and a horizontal coalescing piece 22 are sequentially arranged inside. The outlet pipe 30 is used to discharge the coalesced fluid to the subsequent oil-water separation system.
在工作时，待聚并的油水混合物由进液管10进入，同时由进药管11将化学破乳药剂排入进液管10与其中的油水混合物混合，排入的化学破乳药剂在扩散片12的作用下能够尽量分散到整个进液管10的空间中，以便与油水混合物充分混合。混合了化学破乳药剂的油水混合物进入转换管20后，可以在整流片21的作用下，在转换管20的整个空间内被分为多层，且各层的流动角度为向下方流动，油水混合物中的油在流动过程中相互聚并并逐渐沉降，最终沉降的油滴在聚并片22上实现吸附，油水混合物中微小颗粒的油聚并成大颗粒油后的油水混合物由出口管30中流出，并进入下一步的油水分离系统中，实现油水的分离。When working, the oil-water mixture to be coalesced enters through the liquid inlet pipe 10, and at the same time, the chemical demulsifier is discharged into the liquid inlet pipe 11 through the drug inlet pipe 11 to mix with the oil-water mixture therein, and the discharged chemical demulsifier is spreading Under the action of the sheet 12, it can be dispersed into the entire space of the liquid inlet pipe 10 as far as possible, so as to fully mix with the oil-water mixture. After the oil-water mixture mixed with the chemical demulsifier enters the conversion pipe 20, it can be divided into multiple layers in the entire space of the conversion pipe 20 under the action of the rectifier 21, and the flow angle of each layer is downward flow, and the oil-water The oil in the mixture coalesces and gradually settles during the flow process, and finally the settled oil droplets are adsorbed on the coalescing sheet 22, and the oil-water mixture after the coalescence of tiny particles of oil in the oil-water mixture into large grains of oil passes through the outlet pipe 30 outflow, and into the next step of the oil-water separation system to achieve oil-water separation.
在本实施方式中，处理的油水混合物含油率可以在50％以内，为方便化学破乳药剂与油水混合物充分混合，进药管11位于进液管10中的一端可以为90度的弯头结构，弯曲的方向与油水混合物的流动方向相同，该结构可以减少油水混合物对排药口的影响。扩散片12可以是栅格类的板状结构，其利用相应的阻挡使经过的化学破乳药剂分散成更细小的微粒，从而与油水混合物充分反应。In this embodiment, the oil content of the treated oil-water mixture can be within 50%. In order to facilitate the full mixing of the chemical demulsifier and the oil-water mixture, the end of the drug inlet pipe 11 located in the liquid inlet pipe 10 can be a 90-degree elbow structure , the bending direction is the same as the flow direction of the oil-water mixture, and this structure can reduce the influence of the oil-water mixture on the discharge port. The diffusion sheet 12 may be a grid-like plate structure, which uses corresponding barriers to disperse the passing chemical demulsifier into finer particles, so as to fully react with the oil-water mixture.

The device can be used in offshore platforms, onshore oil fields, and even in future underwater oil-water separation systems.
如图2所示，在本发明的一个实施方式中，具体的扩散片12结构可以是两个十字交叉设置的半椭圆形状的直板，在直板上设置有多个圆孔121。两个直板通过直边相互垂直接触，而椭圆的侧边则分别与进液管10的侧壁接触。圆孔121可以采用规则排列，圆孔121直径以不影响油水混合物的流动为准。As shown in FIG. 2 , in one embodiment of the present invention, the specific structure of the diffuser 12 may be two semi-elliptical straight plates intersecting each other, and a plurality of circular holes 121 are arranged on the straight plates.

The connecting position at is located at the upper part of the axis line of the conversion pipe 20. This structure can make the oil-water mixture form a gradually rising flow trend in the inlet pipe 10, the conversion pipe 20 and the outlet pipe 30, thereby facilitating the light oil to float up and coalesce, while the heavy water descends and stratifies.
在本发明的一个实施方式中，该整流片21有多片且在转换管20的直径内相互间隔地均匀平行设置，各整流片21的侧边可以与转换管20的侧边接触，以使进入的油水混合物只能沿整流片21之间的通道流动。整流片21的倾斜方向为斜向下方，与水平面的夹角a在5°-15°之间。该结构可以降低油水混合物的流速，方便油聚并。聚并片22同样设置有多片且相互间隔水平设置，而且每片聚并片22分别与一扩散片21位置对应，该结构可以避免相应通道中的油水混合物互相混合，提高油聚并过程中的延续性。在本实施方式中，整流片21和聚并片22的长度可以相同。In one embodiment of the present invention, the rectifying slices 21 are multi-piece and are evenly arranged in parallel with each other in the diameter of the conversion tube 20, and the side of each rectifying slice 21 can be in contact with the side of the conversion tube 20, so that The incoming oil-water mixture can only flow along the channels between the rectifying pieces 21 . The inclination direction of the rectifying piece 21 is obliquely downward, and the included angle a with the horizontal plane is between 5°-15°. This structure can reduce the flow rate of the oil-water mixture and facilitate oil aggregation. The coalescing sheets 22 are also provided with multiple pieces and are arranged horizontally at intervals, and each of the coalescing sheets 22 corresponds to a diffusion sheet 21 respectively. continuity. In this embodiment, the lengths of the straightening slices 21 and the merging slices 22 may be the same.
进一步地，在本发明的一个实施方式中，整流片21和聚并片22相互之间以及与互换管20的两端之间留有一定的间隙，具体的间隙大小可以是：整流片21与转换管20进口的距离和聚并片22与转换管20出口的距离相等，而整流片21和聚并片22之间的距离可以为其与进出口两端距离的一半。Further, in one embodiment of the present invention, there is a certain gap between the rectifying sheet 21 and the coalescing sheet 22 and between the two ends of the exchange tube 20, and the specific gap size can be: the rectifying sheet 21 The distance from the inlet of the conversion pipe 20 is equal to the distance between the coalescing sheet 22 and the outlet of the conversion pipe 20, and the distance between the rectifying sheet 21 and the coalescing sheet 22 can be half of the distance from the two ends of the inlet and outlet.

其中，进液管10的直径小于出口管30的直径小于转换管20的直径，三者的比例可以为1：2：6左右。进药管11的直径可以为进液管10直径的1/3。整流片21与转换管20进口之间的距离和聚并片22与转换管20出口的距离可以分别为转换管20长度的1/18。而整流片21与聚并片22之间的距离则为转换管20长度的1/35。Wherein, the diameter of the inlet pipe 10 is smaller than the diameter of the outlet pipe 30 and smaller than the diameter of the conversion pipe 20, and the ratio of the three may be about 1:2:6. The diameter of the drug inlet tube 11 can be 1/3 of the diameter of the liquid inlet tube 10 . The distance between the rectifying sheet 21 and the inlet of the conversion tube 20 and the distance between the merging sheet 22 and the outlet of the conversion tube 20 may be 1/18 of the length of the conversion tube 20 . The distance between the rectifying sheet 21 and the merging sheet 22 is 1/35 of the length of the conversion tube 20 .
