Development Of Four - Phase Separator For Oil - Gas - Water Sand

Henan heavy oil has a light, thin, thick, scattered and small features, ground produced fluid properties is poor, high asphaltene content, high-density, viscosity, sand-carrying capacity, dehydration has been very difficult, especially sand-carrying capacity, is likely to cause the device to plug plague production is a major problem. Because of these characteristics of heavy oil, light oil, compared with in the produced fluid separation and the difficulty of gathering all great. The current process exists:①system energy consumption, low device efficiency;②gathering system is not closed, is not running smoothly, a large oil and gas consumption and other issues. One of the most critical is the low efficiency of dewatering equipment can not effectively solve the problem of sand plug.Combined with heavy oil development and deployment of Henan, heavy oil gathering line processing system to solve the "bottleneck" problem,the project team began to conduct research studies,"Oil sands efficient water separation equipment developed four-phase" project.The project includes the following contents:(1) by increasing the effect of heavy oil dehydration technology research, critical theory to study the factors affecting the dehydration effect, the application of PⅣ technology optimized dewatering equipment suitable for heavy oil pre-separation, coalescing, fluid collection and other components, the proposed Imported cyclone pre-degassing, unidirectional flow channel micro rolled corrugated board rectifier, single phase finned coil heat ramp to strengthen the separation of grit removal and water trough negative overflow outlet diaphragms and other technology, is dewatering equipment and solutions to improve the efficiency of key measures to plug the device, and filter out the appropriate use of the heavy oil demulsifier KM-16;(2) by making equipment Desanding research technique to study the laws of grit inside the device, the device is designed to provide a basis for grit removal devices, negative pressure trough Desanding proposed structure, conducive to sand deposition in the tank, but also to carry out a variety of ways to accumulate sand discharge flow field inside the device would not cause a big impact. Developed a device does not stop Desanding technology, formed a heavy grit removal, sand sand washing fluid set of new technologies;(3) through a four-phase study of separation equipment optimization model, based on the theoretical research findings, to establish a four-phase separation structure optimization model of the device, through the flow field and separation characteristics of the test of the model, in the case of dealing with the same medium, excellent performance the existing separation equipment.By carrying out the project, the issue is difficult for the heavy oil dehydration, developed a suitable heavy oil dehydration and efficient use of the four-phase gas-water separation equipment sands, heavy oil dehydration Desanding solve the problem, to a certain extent, so that heavy oil dehydration technology breakthrough has been made. While fully promote the use of heavy oil in Henan New development and construction, and in other fields have also been promotion, saving a lot of investment in the construction and operation of energy consumption.
