摘　　要：后河地区是陆东凹陷油气最为富集的地区,油气资源丰富,探明率低,勘探开发潜力大。但受成藏主控因素复杂,储层物性差,非均质性强,油藏品位低等多种因素影响,存在优质储层难以准确预测,水平井油层钻遇率低,经济有效动用难等诸多难点问题,严重制约了该地区的勘探开发。研究重点为河地区开发难点为导向,精细刻画优势储层甜点分布,攻关水平井随钻跟踪精准调整新技术,探索直平组合立体开发新方式和水平井分段体积压裂新方法,强力支撑后河地区增储上产。The Houhe area is the most abundant area of oil and gas in the Ludong Depression,with abundant oil and gas resources,low exploration rate,and great exploration and development potential.However,due to various factors such as complex reservoir formation control factors,poor reservoir physical properties,strong heterogeneity,and low reservoir grade,there are many difficult problems such as difficulty in accurately predicting high-quality reservoirs,low drilling rate of horizontal well oil layers,and difficulty in economically effective utilization,which seriously restrict the exploration and development of the region.This research focuses on the development difficulties in the Houhe area,delineating the distribution of sweet spots in advantageous reservoirs,tackling new technologies for precise adjustment of horizontal well tracking while drilling,exploring new methods for vertical and horizontal combination three-dimensional development,and new methods for segmented volume fracturing of horizontal wells.It strongly supports the increase in storage and production in the Houhe area.
