摘　　要：针对海26块原油黏度高,井温低,作业过程中易造成冷伤害,影响防砂效果的实际,开展油层预处理技术研究;同时针对稠油影响树脂砂固结体的性能以及稠油流经固结体时拉力强的原因,开展了增强树脂砂的研究。文中对防砂后油井生产管理进行探索,确定了合理的生产压差。经现场应用证明,配套技术的实施有效地提高了海26块的防砂效果。According to the cold damage problem arising from high-viscosity crude oil and low temperature of formation in downhole operation at Hai 26 block,which influences the sand control effect,the reservoir pretreatment technique has been studied to solve the problem.At the same time,because heavy oilaffects the properties of resin sand cumulates,reinforced resin bonded sand has been studied too.Through studying the production management of sand prevention wells,reasonable pressure difference was decided.The results of field test proved that the sand control effect has been effectively improved by using matching technology.
