摘　　要：复杂断块油田桥 2 9块一类层严重水淹 ,注水启动二、三类层难度大 ,已进入中高含水开发阶段。分析区块开发面临的主要矛盾是 :井网密度大 ,平面调整余地小 ;含油层系单一 ,纵向上无法进行层系调整 ;储层非均质严重 ,砂体分布不稳定 ,设计经济效益井难度大。根据区块开发实际 ,深化地质基础研究 ,通过构造精细解释 ,储层综合评价 ,储量动用状况分析及剩余油分布规律研究 ,确定了区块的主要挖潜方向 :认识程度较低的断层边角部位构造复杂带、具有多套含油层系的屋脊断块高部位及局部剩余油富集区。通过应用双靶定向井调整挖潜技术 ,对改善区块开发效果起到了显著作用。The Q29 block is very complicated oilfield; it's good productive layers are watered seriously, and the bad layers are hard to be produced. The development of oil field entered into later stage of middle or high water cut. The more serious problems we faced are: the well density is too high to be adjusted; the productive layers are too single to adjust mini_layer longitudinally; Q29 oilfiled is an homogeneous reservoir. It is difficult to design economic adjustment wells. Based on the productive condition, we do a lot of fundamental geologic study, including: fine reservoir description, performance analysis, reservoir evaluation and remaining oil distribution law. At last, we find the potential tapping target: complicated block area, high structure position with rich remaining oil. Application of double target directional well technology in Q29 oil field, we gain a better productive result.
