摘要: 复杂小断块油藏的剩余油在开发后期极为复杂,不仅受多个因素的控制,同时,某一种因素单独控制的剩余
油非常分散且数量有限。针对高浅南区小断块油藏边水发育的特点,考虑剩余油的主控因素、断块油藏的形状、天然
能量的充足程度以及能量供体等将边水断块油藏划分为3 类:开启型边水断块油藏、半封闭型边水断块油藏以及封闭
型边水断块油藏。并研究了每种油藏类型的剩余油分布特征和挖潜潜力。发现:开启型边水断块油藏采出程度最高、
剩余油少而分散;封闭型边水断块油藏采出程度最低、剩余油多而连片;半封闭型边水断块油藏介于两者之间。在以
上研究的基础上,根据每种油藏类型的特点提出了下一步挖潜的技术对策。

Abstract: The residual oil of small complex fault block reservoirs is extremely complex in the late stage of development.
There are many factors controlling it. And the residual oil controlled by a single factor is dispersed and limited. Considering
the main controlling factors of the residual oil,the form of the fault block reservoirs,the adequacy of natural energy and energy
provider,we divide the edge-water fault block reservoirs into three categories. They are open-type edge-water fault block
reservoir,semi-closed edge-water fault block reservoir and closed edge-water fault block reservoir. Based on the studies on the
distribution features of the residual oil and the exploiting potential of each reservoir type we find that the open-type edge-water
fault block reservoir is of the highest degree of recovery percent and the residual oil is few and dispersed,that the closed edgewater
fault block reservoir is the lowest degree of recovery percent and the residual oil is much and contiguous,and that the
semi-closed edge-water fault block reservoir is between the above two. On the basis of the above study we propose the technical
countermeasures for farther development according to the characteristics of each reservoir type.

Key words: residual oil, edge water, the faulted block reservoir, the type of reservoir, natural energy, the Geo Qiannan area
