1、 毕业设计(论文)毕业设计(论文) 题目:蒸汽开采稠油油藏提高开发效果研究 2012014 4 年年 9 9 月月 2 22 2 日日 I 摘摘 要要 齐40块历经20年的开采已进入了吞吐开采的中后期, 为了提高齐40块的采收率, 分别于98年、2003年进行了蒸汽驱的实验,2006年在次此基础上进行工业化转驱, 随着汽驱时间的增长,暴露出油井高含水、高温、油井井况差、频繁作业、注汽井 注汽不合格、等矛盾,为了解决上述矛盾从机械封堵、高温堵窜、优选抽油泵、大 修更新、完善层系、吞吐引效、调整参数、下大泵增排等方面进行研究和实践,缓 解了蒸汽驱开发中的矛盾,使蒸汽驱达到了预期的效果。 52井组位
2、于齐40块中部的主体部位。含油面积1.41km2,石油地质储量为1333 10 4t。其中莲油层组有27个井组,莲油层组有38个井组。区内构造简单,主 要发育有5条断层,构造形态为单斜构造,地层由北西向南东倾没。52井组于2006 年12月开始转驱,根据转驱前地层温度、压力分布状况等因素,转驱顺序选择在地 层温度较高(45度) 、压力水平较低(1-2MPa)的区块中部地区优先转驱,效果明 显。 关键词:52 井组,优先转驱,蒸汽驱, 注水; 关键词 2 水间; 关键词 3 封隔器 II ACT ABSTR Will summarize the thick oil to fall mounts
