摘要
浅层油气藏成藏条件应达到：圈闭构造面积大、储层的岩性和物性好、油源充足、粘土矿物对油气运移聚集成藏的作用显著。本文通过对AlgenaX盆地Y油田古生代浅层油藏的实例剖析，说明了该油田产量低的主要原因：（1）盆地构造面积小；（2）油源供应不足；（3）粘土矿物不具备催化生油、气的条件；（4）岩性太细，要灌满储层油气需要克服高的排驱压力。
Shallow reservoir formation conditions include large trap structure area,good lithological and physical properties,sufficient oil sources. great effect of clay minerals on oil and gas migration.Through case analysis of Paleozoic shallow reservoir of Y oilfield in X basin of.Algeria, the main reasons for low productivity are(1) the basin structure area is small;(2) the oil sources is insufficient;(3) the clay minerals have no catalysis for oil and gas forming;(4) the rock is too fine.So to top up a reservoir needs to overcome high replacement pressure.
