Abstract


With the the Liaohe Oilfield horizontal wells in the application of technology , improved oil recovery . However, due to the wellbore horizontal wells special structure made ??deviated section and the horizontal section is longer, and the changes in the wellbore axis irregular factors , the conventional horizontal wells workover technology is different from the ordinary conventional oil wells operating . In particular , heavy oil horizontal well the sand washing construction, because the more complex of heavy oil horizontal wells , construction card Drills cause significant economic losses . Brief introduction to the current horizontal wells red sand technology methods and techniques based on a systematic analysis of portable sand model , combined with the actual information and data through horizontal wells , summed up the horizontal wells the scene red sand smallest row amount parameter table . Research and analysis of the crude viscosity of the heavy oil blocks horizontal wells in Huanxiling well dropout situation , the effective viscosity reduction and well plugging technology for heavy oil blocks horizontal wells . Parameters and strength parameters of the string matching combined with horizontal wells , horizontal wells the scene red sand smallest displacement parameters table , the viscosity reduction of horizontal wells and well plugging technology proposed Huanxiling heavy oil blocks horizontal wells sand washing techniques and supporting tools provide a reasonable proposal , washed sand horizontal wells for heavy oil blocks . At home and abroad in horizontal wells red sands operations generally small to carry out the study of the red sand parameters of the horizontal wells , the master horizontal wells flow sand-carrying law, determine the the red sands parameters and red- sand way , the correct match red sand equipment and facilities , to avoid blind construction , to prevent the construction of the red sand caused the sticking turn overhaul , red sand in advance Difficult less sand back to the low efficiency of red sand , material consumption , job accounting for the well long cycle and increase crude oil production has significance. Thus , to carry out the Liaohe oilfield joy Ridge area heavy oil horizontal wells red sand parameters and the application of sand washing technology is particularly important .
