Research And Application Of The Oil Gas Water Measuring Technique Based On GLCC

In view of offshore oil production per well, gas-oil ratio and water content there is a big difference, under different conditions to improve measurement accuracy of crude oil needs, in a traditional test separator and multiphase flow meter based on the strengths and weaknesses, by optimizing the design and system integration, development of gas-liquid cylindrical cyclone separator-based (GLCC) technology, oil and gas wells flow measurement device. Developed GLCC + measure of production separator measurement mode, the metering system has the equipment, weight and take up less space, for single well production in a floating wide range of large gas-oil ratio, as well as measuring the results of the characteristics of high degree of accuracy.Through contrastive analysis of GLCC and traditional horizontal-type separator superior, shortcoming, confirmed this production measuring system's measurement effect through the software simulation and the experimental test, in order to satisfy the measuring accuracy which the customer proposed to meet±5% requirements. GLCC separator and production of measuring directly connected, in the export of oil phase separator tubes on the road to configure both the same size scraper meter in parallel with a prepared one to measure the volume of flow of crude oil. Two of the same specifications used in tandem microwave moisture instrument to measure volume of water. GVF tables used to monitor a fraction. And gas at sea road, using mass flow and density measurement of the flow of media. Gas pipeline with pressure control to maintain the operating pressure.Siemens S7-200 of the PLC control system for data collection, level and pressure control, remote transmission of data.and the overall system takes spatial small.First, the crude oil intermixture enters GLCC, GLCC can be able to separate most of gas to reduce in the intermixture air void; Second, the horizontal-type separator can separate oil free moisture; Third, the entire measuring system takes the space to be small, to enable the oil phase measuring accuracy to meet±5% requirements.
