花土沟油田复合河道砂体构型研究
|
摘要
对花土沟油田上干柴沟组的砂体特征进行了研究,结果表明,花土沟油田三角洲前缘复合河道内单一河道边界具有5种识别标志:河间沉积、高程差异、厚度差异、侧向叠加、河道砂体的"厚–薄–厚"组合;单一河道砂体宽度80～200 m,厚度2～5 m。对三角洲前缘复合水下分流河道内部的单砂体进行定量识别,结果显示单砂体间主要有孤立型、对接型、叠加型三种接触关系;油田开发生产实践证实了单砂体划分比较合理。
The sand body characteristics of the upper Ganchaigou formation in Huatugou oilfield were studied.The results showed that the single channel boundary in the delta front of Huatugou oilfield has five identification marks: inter channel deposition, elevation difference, thickness difference, lateral superposition,and 'thick-thin-thick' combination of channel sand body. The sand body of a single channel is 80 ～ 200 m wide and 2～5 m thick. Quantitative identification of single sand bodies in delta front composite underwater distributary channel was carried out. The results show that there are three main contact relationships among single sand bodies: isolated type, butt type and superimposed type. The practice of oilfield development and production proves that the division of single sand body is reasonable.
