针对江汉边远油田的原油物性及其外部条件，研制出一种新型高效的XSL－Ⅰ型三相分离器。并从强化分离元件、提高容积利用率入手，通过多次改变被分离介质的流向及流速的做法，采用新颖高效预分离头、异形蝶阀、蛇形板整流器、均质布液板、可调水堰套管及出油（水）阀等新技术，有效地提高了设备利用率及运行可靠性，使其在低温脱水时具有效率高、能耗低、操作管理方便、处理效果好等特点，深受使用单位的欢迎。现场检测结果表明，凝固点为28．5℃，粘度（50℃）为1．3MPa·s，含水为55％的原油经该分离器处理后可达到：出口原油含水≤0．2％，污水含油≤100mg／L，出口含盐≤120mg／L，气中含液≤0．05g／m3。
Aiming at the physical properties of crude oil in Jianghan Border Oilfield and its external conditions, a new and efficient XSL-Ⅰ three-phase separator was developed. And from strengthening the separation of components, increase volume utilization to start by repeatedly changing the direction of the medium is separated from the flow rate and the practice of using innovative and efficient pre-separation head, shaped butterfly valve, snake plate rectifier, homogeneous cloth plate, adjustable water Weir bushing and oil (water) valve and other new technologies, effectively improve the equipment utilization and operational reliability, so that it has high efficiency at low temperature dehydration, low energy consumption, easy operation and management, and good treatment effect, Welcomed by the use of units. The field test results show that the crude oil with the solidification point of 28.5 ℃, viscosity (50 ℃) of 1.3MPa · s and water content of 55% can be obtained after the separator treatment: outlet crude oil ≤0.2%, sewage oil ≤100mg / L, export salt ≤120mg / L, liquid gas ≤0.05g / m3.
