摘　　要：分析研究了孤东油田稠油区块地质特点和蒸汽吞吐开采中防砂及配套工艺存在的问题 ,优化了一套适合孤东稠油区块注蒸汽开采的防砂及配套工艺。现场应用表明 ,“涂敷砂 +金属棉滤砂管”复合防砂方法适合于孤东油田稠油疏松砂岩油藏蒸汽吞吐开采 ,成功率高 ,有效期长 ;注蒸汽后配套过泵电加热工艺 ,可提高稠油注汽开采效果延长注汽周期 ;The geologic characteristics of viscous oil blocks and the problems of sand control in production by cyclic steam injection are studied analytically,a set of sand control and its support processes are optimized,which are suitable for producting by steam injection in the viscous oil block of Gudong oilfield Field application shows that a combined sand control method constituted by coated sand with metallic cotton sand filter tube is appropriate for viscous oil production by cyclic steam injecting in loose sandstone reservoirs of the oilfield,which is of high success rate and long effective period;a through pump electric heating process is used after the steam injection, to improve the effect of viscous oil recovery and lengthen the steam injecting cycle, optimizing perforating process and pretreatment of antiswelling are effective measures for promoting success rate of sand control in loose argillaceous sandstone reservoirs
