| 摘 要： | 川口油田西南区延长组长6油层组储集层岩石类型以长石砂岩为主,颗粒间多为点-线接触关系,孔隙式胶结,总体具有成分成熟度低、结构成熟度高,低孔低渗特征.粒间孔-溶孔为储层的主要储集空间.沉积相带、矿物成分及砂岩粒径等是影响研究区储集层性质的重要条件和关键因素,较强的压实作用、胶结作用是该区形成低孔低渗储集层的主要因素,溶蚀作用为储集层的主要增孔因素. |
| 关 键 词： | 川口油田 延长组 储层特征 储层物性控制因素 |

| Abstract: | The Chang 6 reservoir in the southwest area Chuankou Oilfield is composed of feldspathic sandstones and lithic arkose sandstones,which is characterized by low compositional maturity,high textural maturity and low- porosity and low-permeability.There is point-line contact form and porous cementation type between rock grains.The main pore types are granular pore and secondary dissolution pore.The sedimentary facies,mineral composition and grain diameter of the sandstones are the key factors of influencing the reservoir formation and evolution.The reservoir has undergone the strong compaction and cementation,which are the main factors of resulting in the low-porosity and low permeability of the reservoir.Dissolution is the main factor for increasing the porosity of the reservoir. |
| Keywords: | Chuankou Oilfield Yanchang Formation reservoir characteristic control factor of reservoir property |
