摘　　要：大港油田埕海一区开发井基本都是大斜度井,水平位移长,水垂比高,一些大斜度井完井采用套管固井,管内悬挂筛管的防砂完井方式,而在易出砂地层采用独立筛管防砂完井。由于防砂精度单一,筛管易堵塞,防砂效果差,而挤压砾石充填防砂工艺技术是用携砂液以挤压充填方式对近井地带充填一定量的砾石,用循环充填方式对筛管与井筒环空进行砾石充填,形成多级挡砂屏障,防砂效果好。同时针对埕海一区大斜度井的特点及生产储层的地质情况,优化施工参数,在庄海8Es-L8井率先成功实施,取得良好效果,完善了大斜度井的完井方式,实现了开发井的高效开采。The development wells at the first region of Chenghai in Dagang oilfield are deviated wells basically,horizontal displacement of which is long,and the water ratio of vertical is high. Well completions in some of high angle wells are used of casing cementing,sand control screen pipe suspension,and independent screen sand control completion in easy sanding formation. Because sand control precision is single,screen is easily plug,and sand control effect is poor,the extrusion gravel packing sand control technology is the use of sand carrying fluid to squeeze the gravel packing method of near well-bore filled with a certain amount of gravel packing,the sieve and wellbore annulus with cyclic filling mode,multilevel sand barrier is formed,and sand prevention effect is good. At the same time,according to the geological the situation of Chenghai deviated wells area features and production of reservoir,and being optimized the construction parameters,the first successful implementation of Zhuanghai8Es-L8 well has been implemented successfully,which has a good effect,improves the high inclination well completion method,and makes true of high efficiency mining to development well.
