大庆油田葡萄花油层有效厚度的确定

The Effective Thickness Determination for Daqing Oilfield Putaohua Reservoir

依据单井有效厚度下限的前提,考虑到大庆油田葡萄花油层储层发育的因素,对葡萄花油层的单井、单层有效厚度下限进行了探讨。对于Ⅰ、Ⅱ、Ⅲ类储层,单井有效厚度下限分别为1.0 m、1.2 m和1.8 m。在单井有效厚度小于1.0 m的情况下,Ⅰ、Ⅱ类储层的单层有效厚度下限为0.5 m和0.6 m。从而为经济有效地开发葡萄花油层提供有利的保证。

According to the precondition of lower limitation of effective thickness for single well,in consideration of the factor of Daqing oilfield Putaohua reservoir development,the Putaohua reservoir＇s single well、lower limitation of effective thickness for single-deck are discussed.The lower limitation of effective thickness for single-deck ofⅠ、Ⅱ、Ⅲ type reservoir separately is 1.0 m,1.2 m and 1.8 m.When the effective thickness for single-deck is less than 1.0 m,the lower limitation of effective thickness for single-deck ofⅠ,Ⅱare 0.5 m and 0.6 m.Thus offers pledge for exploit the Putaohua resvoir economically and effectively.
