辽河油田齐40块渗流屏障研究
|
摘要
以辽河油田齐40块莲花油层为例,明确热采储层渗流屏障的识别方法、评价标准及表征模型,实现对全区内非取心井以及取心井未取心层段的渗流屏障的划分。研究表明,齐40块渗流屏障类型主要有沉积屏障、成岩屏障和构造屏障3类,泥岩隔夹层是导致水淹形式复杂的主要地质因素,封闭性断层是最主要的渗流屏障。
We took the lotus oil of Qi 40 blocks in Liaohe Oilfield for an example,to determine the identification method,evaluation criteria and characterization models of the seepage barrier in thermal recovery reservoir. And we also achieved the seepage barrier's division of the non-coring wells and the coring well whose layer segments are not taken. Studies have shown that: there are three types of seepage barrier in Qi 40 block,such as sediment barriers,diagenetic barriers and construction barriers. The main geological factor is mudstone interlayers,which resulted in complex water flooded form. Sealing faults is the major seepage barrier.
