摘要：

夫特砾岩油藏岩石结构、成分成熟度低,胶结物以凝灰质为主,具复模态结构,储层物性主要受裂缝影响。裂缝对孔隙度贡献较小,对渗透率贡献较大。裂缝充填差。多与断层平行,纵向上主要发育在砾岩段上部,平面上受断层影响明显。根据胶结物的类型、含量及裂缝发育程度,将储层划分为裂缝型、孔缝型、孔隙(洞)型三类,认为哈22断块三类储层均较哈43断块发育。根据此研究,在开发中确定了合理的注采比和压力水平,调整了注采层系及系统,在应用中取得较好的效果。

Abstract:

The textural maturity and compositional maturity of Fute conglomerate oil reservoirs are low,the cements are mainly tuffaceous materials with double modular texture.Reservoir physical property is affected by fractures.The fractures,however,made little contribution to porosity,but considerable contribution to permeability.According to the types,the contents of cements,and facture development,the reservoirs could be divided into fracture,pore fracture and pore cave types.It is suggested that the above mentioned reservoirs of Ha-22 fault block developed well than those of Ha-43 fault block.On this basis,reasonal ratio of injection to recovery and presure,the injection and recovery stratigraphic horizons are determined and the results are satisfactory.

Key words: conglomerate oil pool, reservoir property, types of fracture, pore assemblage, application
