摘　　要：针对单家寺油田单2西块开发历史长和低速、低效、高含水的现状,在重新进行精细油藏描述的基础上,对储层的非均质性、油水关系及构造特征取得了新的认识,并有针对性地提出立足蒸汽吞吐,综合运用局部井网加密、油层底部避射、逐周期增加注汽强度等技术,对老井实施老井新投、边部老井提液和调层上返等措施。方案实施后,单井吞吐效果较好,经济效益显著。对同类油藏的开发有一定的指导意义。Shan er xi block in Shanjiasi oilfield has been developed for a long period, and is producing at low rate, low efficiency and high water cut. Precise reservoir description is conducted again to re - understand the heterogeneity, oil - water relation and the structure of reservoirs . Techniques proposed accordingly are taking cyclic steam stimulation as a base, local well pattern thickening, not perforating bottom reservoir, increasing steam injection intensity cycle by cycle, reactivating old wells, increasing fluid production, and producing layer by layer upwardly. After implementing of these measures, single well cyclic steam stimulation effect is improved, and economic benefit is remarkable . This may guide the development of similar reservoirs.
