Based on the low permeability features of volcanic trachyte, the phenomena of intermittent flow and water breakthrough are showed in the process of production from the aspects of the lithologic character, oil layer distribution, pores and fractures, pore radius and relative permeability curve.
根据火山粗面岩的低渗透特点,从岩性特征、油层分布、孔隙、裂缝、孔道半径和相渗曲线等方面,揭示了开发生产中的间歇自喷和含水突进等现象,探讨了油藏埋深和油水界面的关系,建立了黄沙坨油田火山岩裂缝油气藏的储层评价指标。
2.
Huangshatuo oilfield is a fractured volcanic trachyte reservoir driven by edge and bottom water,the reservoir belongs to fracture-pore medium and the development degree of pore and fracture dominates the production status of oil well.
黄沙坨油田是裂缝性边底水火山粗面岩油藏,储层属于裂缝-孔隙型双重介质,裂缝、孔隙等发育的程度、状况控制着油井的生产状态。

补充资料：粗面岩
| 粗面岩 trachyte 一种中性火山喷出岩。成分相当于正长岩。浅灰、浅黄或粉红色。具斑状、粗面状、球粒状结构和块状、流纹状、气孔状构造。通常分为钙碱性粗面岩和碱性粗面岩两种类型。钙碱性粗面岩主要由碱性长石、斜长石和少量暗色矿物组成。碱性长石以透长石为主，次为歪长石，暗色矿物主要为黑云母，含少量角闪石和辉石。碱性粗面岩的特点是含适量碱性暗色矿物，有时含少量似长石矿物；浅色矿物主要为碱性长石（透长石、正长石、歪长石等），斜长石含量少。还可进一步分为以含钾长石为主的钾质粗面岩和以含钠长石为主的钠质粗面岩等。 |
