摘　　要：为确定大庆油田龙西地区TA区块致密油储层有效厚度经济界限,解决薄层压裂选层取舍难题,采用投入产出比法和产量经济界限法综合确定了龙西地区TA区块致密油直井三类储层有效厚度经济界限,即致密油Ⅰ类、Ⅱ-1类、Ⅱ-2类油层有效厚度经济界限均可达0.2 m。该方法为大庆外围油田致密油直井压裂选层提供了依据和技术借鉴。To facilitate thin-layer selection for fracturing of tight oil reservoirs in TA block in Longxi area of Daqing Oilfield,the input-output ratio method and the production economic limit method were used to comprehensively determine the economic limit of the effective thickness of three types of tight oil reservoirs in vertical wells in TA block.The results show that for all classⅠ,classⅡ-1 and classⅡ-2 tight oil reservoirs,the economic limit of effective thickness can reach 0.2 m.This method provides a basis and technical reference for fracturing layer selection of tight oil vertical wells in peripheral oilfields of Daqing.
