摘要
塔河油田AT井区属于碎屑岩油藏,储量丰富,但由于地表环境属国家级自然保护区,环境保护等级要求很高,增加了钻井开发的难度。如果利用常规钻井技术方案进行施工,不仅油藏动用程度低,开发成本高,而且极易造成环境破坏。根据油藏地质特征及地面环境要求,在丛式井钻井开发工艺技术研究分析的基础上,优化设计了针对AT井区特殊环境要求的丛式井钻井开发方案。实践应用结果表明,丛式井组优化设计方案能够有效控制油藏储量96万吨,井场数由9个减为1个,避免了对自然环境破坏的同时,降低了产能建设投入成本,进而提高了整个油气田的经济效益。
AT well site is clastic reservoir,and it is difficult for development by normal drilling technology because of environment protection.According to geological character and environment,on the basis of researching on cluster well technical parameter,the optimum design scheme is supplied.The results show that,cluster well optimum design scheme can control 96*104T oil,number of well site is decreased to only one,not only protect environment but also increase economic benefit.
