摘要珠江口盆地恩平凹陷新近系浅层砂岩存在疏松现象，开发过程中出砂问题严重，为油田高效开采带来了很大的困难.通过对恩平凹陷M油田韩江组地层的沉积成因、成岩作用及油气充注期次的研究，揭示了砂岩疏松的主要控制因素，为后续根据属性情况进行井位调整等生产措施奠定了基础.研究结果表明，韩江组砂岩疏松的控因有3方面：一是研究区韩江组属于三角洲前缘沉积环境，粒度细，泥质含量高，不利于胶结成岩；二是成岩程度弱，属于早成岩A期，胶结程度弱；三是油气充注严重抑制了成岩作用.

Abstract：The unconsolidated Neogene shallow sandstone in Enping Sag of Pearl River Mouth Basin causes severe sand production in the development process and brings great difficulties to the efficient exploitation of oil fields. Through the study of sedimentary origin, diagenesis and oil-gas charging period of Hanjiang Formation in M Oilfield of Enping Sag, the paper reveals the main controlling factors of unconsolidated sandstone, which lays a foundation for subsequent production measures such as well location adjustment according to attributes. The results show that there are three controlling factors contributed to the unconsolidated sandstone as follows:1) Hanjiang Formation in the study area is of delta front sedimentary environment with fine grain size and high mud content, which is not conducive to cementation; 2) the diagenetic degree is low, belonging to stage A of early diagenesis, with poor cementation; and 3) the diagenesis is severely inhibited by oil-gas charging.

Key words： Pearl River Mouth Basin Enping Sag Hanjiang Formation unconsolidated sandstone diagenesis
