摘　　要：桥66块是桥口油田近年来新发现的区块,2002年投入开发,经生产证实其产量下降快,2002年8月区块日产油139.9t,2006年8月下降为59.2t,年自然递减高达57.7%;影响桥66块开发效果的因素是构造复杂、砂体变化大、非均质性较强、油藏埋藏深、有效厚度小、含油层系较单一、单层含油面积小、钻井成本高。针对区块地质特征及开发特点,开展了油藏精细描述技术研究,通过应用实施,区块产量有所回升,且由III类油藏上升为II类油藏开发水。In recent years, the Qiao66 are newly discovered block in the Qiaokou oilfield,since it put into developed in 2002, verified its output drops fast, block Nissan oil is from 139.9tons in August of 2002 dropped to 59.2 tons in August of 2003, decreases progressively annually naturally up to 57.7%, influenc- ing the Q66 block factors of developing result are that the structure is complicated, sands change in a big way, the heterogee is stronger, bury deeply in the oil reservoir, effective thickness little, oil--bearing formation getting more single, oil area little , well drilling with high costs. To the geological characteristic of block and characteristic of developing , describe technical research meticulously after launching the oil reservoir, through it is implement to use ,the output of block rises in some kind of degree, and oil reservoir becomes Ⅱ oil reservoir develop competence by Ⅲ.
