河南双河油田Ⅳ1-3层系微型构造研究

STUDY ON MICROTECTONICS ON Ⅳ1 3 SERIES OF STRATA IN THE SHUANGHE OILFIELD, HENAN

对微型构造的定义、类型及形成机制作了简要论述。微构造对油水的分布起着重要的控制作用。油层内的倾斜和起伏会引起油水的重新分异，其结果是正向微型构造区内形成剩余油富集区，斜面次之；负向微型构造区形成高含水区。

This paper briefly discusses the definition, genesis mechanism and classification of the microtectonics. Microtectonics is an important factor to control oil water distribution. The inclination and relief in oil layers may cause oil water redifferentiation. Consequently, there is rich remnant oil in positive microtectonic areas, less oil in inclined plane areas, and rich water in negative microtectonic areas mostly. Hence, great attention must be paid when the readjustment and disposition of hole net are dealt with.
