摘　　要：敏感性疏松砂岩油藏成岩性差,泥质含量高,出砂严重,采用低防砂强度的化学防砂、刚玉滤防砂有效期短,而高防砂强度的压裂充填防砂、金属滤防砂易堵塞降产。为此,设计研制了一种新型的高强高渗低阻防砂筛管,采用过油通道为主的防堵塞、易排砂管体结构,强化了地层微粒的有效排出,实现适度挡砂;采用网状支撑防砂器结构,提高了滤砂管的机械强度,实现了大斜度井的安全下入,长效生产。目前,现场已试验117井次,防砂成功率95. 7%,平均单井日产液量提高206%,日增油2. 9 t,动液面上升462 m。现场应用表明,新型防砂筛管不但实现了油井防砂,而且有效解放储层,提高了油井产能。Sensitive loose sandstone reservoirs are characterized by poor diagenesis,high shale content and serious sand production.The chemical sand control and corundum filter sand control with low strength has a short effective period.Besides,the fracture-packing sand control and metal filter sand control with high sand control strength are easy to be plugged and reduce production.Therefore,a new type of sand control screen with high strength,high seepage and low resistance has been developed.The pipe capable of blockage prevention and easy sand discharge is adopted which is mainly based on oil passage,it strengthens the effective discharge of formation particles and achieves moderate sand retention.and net supporting structure is used to improve the mechanical strength of the screen,ensuring safe running in hole and long-term production in highly deviated wells.At present,tests on117 wells have been carried out,the success rate of sand control is 95.7%.The average production of single well is increased by 206%,oil production per day is increased by 2.9 t,and the dynamic liquid level is increased by 462m.Field application shows that the new sand control screen achieves sand control in oil well,and effectively releases the reservoir resources,and the productivity of oil well gets improved.
