[Abstract]:Most of the peripheral oilfields in the western part of Daqing are low-yield and low-permeability oilfields, with poor physical properties of crude oil, low single well production, dispersed oil fields, high investment in unit productivity construction, high energy consumption of gathering and transportation, and about 80% of natural gas is consumed in oil and gas gathering and transportation. Therefore, low temperature gathering and transportation technology has great potential for energy saving. It is necessary to carry out research on cooling gathering, transportation and treatment methods of low yield oil fields in accordance with the actual situation of low yield blocks in the western periphery of Daqing. In order to study the methods of cooling gathering and transportation in low-yield oilfields, it is necessary to first make clear the properties and variation laws of water-cut crude oil which affects the gathering and transportation characteristics of each oilfield block. Therefore, combined with the physical properties of crude oil in the low-yield blocks in the western periphery of Daqing, The related laboratory experiments of crude oil cooling gathering and transportation technology were carried out under geographical conditions and production status. Crude oil and produced water samples were obtained from 12 oil field blocks and 5 joint stations. The rheological and temperature properties of crude oil under different water cut conditions were measured experimentally. It can provide reliable basis for the determination of the minimum temperature and the best gathering and transporting velocity of crude oil in each block, determine the emulsifying characteristics of crude oil in each block, and determine the phase transition point of oil-water emulsion, so as to determine the minimum amount of water mixed in water gathering and transportation. Through the demulsification and dehydration experiment of crude oil, the demulsifier corresponding to the properties of crude oil in each block was selected, and combined with the electric dehydration process, the treatment effect under different dehydration parameters was determined, and the dehydration system was determined. It can provide the basis for the low-temperature treatment of the produced liquid, and provide the theoretical basis for establishing a low-temperature gathering and transportation management system suitable for the low-yield block in the western periphery of Yu Daqing, so as to achieve the purpose of saving energy and reducing consumption.
