月东构造储层敏感性实验及油层保护技术

方法利用储层敏感性评价实验，寻找油层保护措施。目的解决月东构造稠油开采中的油层保护问题。结果月东构造是一个敏感性较强的储层，所使用的钻井液与储层配伍性较好，伤害指数０７＜Ｄｄ＜１，储层为轻度伤害；据此，对月东构造开发全过程中油层保护问题提出了具体的要求和措施。结论解决了海上油田稠油开采过程中的油层保护问题，节约了作业成本，取得了较好的经济效益和社会效益。同时为海上同类油田提供了可借鉴的油层保护技术和措施

Reservoir sensibility experiment and reservoir protection technique of Yuedong structure.

MethodReservoir protection measures are discussed through reservoir sensitivity evaluation experiment. PurposeTo solve the problem of reservoir protection during heavy oil recovery in Yuedong structure. ResultYuedong stucture is a very sensitive reservoir. The compatibility of drilling mud and reservoir is fairly good with damage index of 07< D d<1 which is not severe. Requirements are put forward in the whole process of the development of Yuedong structure in terms of reservoir protection. ConclusionReservoir protection problem in offshore heavy oil production is solved. Some amount of operation cost is saved. Economical and social benefit are obtained. Meanwhile, reservoir protection technique and corresponding measures are provided for similar offshore oil field.
