[Abstract]:Steam stimulation in horizontal wells is a difficult problem for heavy oil production. According to the field conditions, this paper studies the flow law of solid-liquid two-phase flow field in horizontal well tube after steam huff and puff under different well conditions and fluid physical properties. PIV particle imaging velocimetry system can be used to test the whole flow field. Therefore, PIV system is used to collect the data of solid-liquid two-phase flow field in horizontal circular pipe. Firstly, the flow parameters of liquid and solid particles in horizontal well at the later stage of steam huff and puff are determined. Then 1 study the measuring principle and application method of PIV device, 2 determine the design scheme for the flow site of solid and liquid two-phase flow in horizontal wellbore, 3 test wellbore velocity, liquid viscosity, solid particle volume fraction respectively, The effects of four parameters of particle size on solid-liquid two-phase flow. 4. Imaging the tracer particles and analyzing the correlation between the collected images. Through studying the measuring principle and using method of PIV device, the corresponding physical experiment simulation is carried out. The influence of wellbore velocity, liquid viscosity, solid particle volume fraction and particle size on wellbore flow state is considered in PIV test. The factors that have the greatest influence on the flow state, such as the volume fraction of solid phase, the height of fixed layer and the pressure drop of liquid phase in the wellbore, are found out, and the influence of different parameters on the carrying capacity of solid particles in the wellbore is obtained. It provides a theoretical basis for the design of appropriate sand production process in horizontal wellbore in the later stage of steam huff and puff in sandstone reservoir and the comprehensive control of thermal recovery sand in heavy oil reservoir.
