摘　　要：随着勘探开发程度的不断深入,下组合储层在每年提交储量中的比例逐年升高。延长油田探明、预测和控制储量中,这类储层石油资源潜力巨大,但目前尚未找到有效的开发对策。通过对该区块井筒及井下压裂管柱的研究,对单层及多层压裂提出了优化的管柱结构,进行了射孔参数优化,并认为射孔位置选择在岩性较纯、渗透率较高的位置。With the deepening of the degree of exploration and development,the proportion in submitted reservoir reserves annually increased year by year. This type of reservoir oil resources has great potential in the proven,predictable and controlled reserves of Yanchang oilfield,but an effective development countermeasure has not been found. Through the research on the bore hole shaft and down-hole fracturing string at this block,optimization string structure is proposed for the single layer and multilayer fracturing,the optimized perforating parameters are carried out,and it is thought that the perforating location should be chosen at position of pure lithology and high permeability.
