摘要

以哈法亚油田白垩系Mishrif组为例,结合岩心、302块薄片及2 507个实验分析数据等资料,对颗粒滩储集层的地质特征、分布规律及其主控因素进行分析。Mishrif组发育多种类型、多期次的颗粒滩储集层,以颗粒灰岩为主,其次为粒泥灰岩和泥粒灰岩,其形成和分布主要受相对海平面升降、古地貌以及同生—准同生期溶蚀作用控制。相对海平面的升降控制颗粒滩的类型及发育期次,在海平面下降旋回有利于厚壳蛤碎屑、介屑、砂屑和似球粒等滩体沉积,其中以厚壳蛤碎屑滩和介屑滩沉积期海平面最低,储集物性最好,最大孔隙度为33.94%,最大渗透率达764.571×10-3 μm2,平均渗透率为45.81×10-3 μm2;古地貌控制了高能相带与大气淡水溶蚀程度,沉积期海底古地貌高地控制了高能相带的形成与展布,而隆升剥蚀期古地貌高地溶蚀强度大、储集层物性好,平均孔隙度为14.78%,平均渗透率为7.849×10-3 μm2;同生—准同生期溶蚀作用形成了绝大多数的有效孔隙,是研究区颗粒滩储集层形成的关键。图8表3参22

Abstract

The geological features and distribution regularity of the grain bank reservoirs of the Cretaceous Mishrif Formation in Halfaya Oilfield and their main controlling factors were analyzed based on coring data, 302 pieces of thin sections and 2507 experiment data points. Various types and multiple phases of grain bank reservoirs are developed in Mishrif Formation, which are dominated by grainstone, followed by wackestone packstone. The formation and distribution of grain bank reservoirs are mainly controlled by relative sea level change, paleogeomorpholoy and contemporaneous-penecontemporaneous dissolution. Relative sea level change controls the types and development phases of grain banks. When the sea level falls, rudists, coquina, arene and pelletoids are extensively deposited, among which, rudists clastic bank and coquina bank that are deposited at the lowest sea level have the best reservoir properties, with a maximum porosity of 33.94%, maximum permeability of 764.571×10-3 μm2 and an average permeability of 45.81×10-3 μm2. Paleogeomorpholoy controls high-energy facies belt and the dissolution of meteoric water. The submarine paleohigh controls the formation and distribution of high-energy facies belt during depositional period. However, during uplifting and denudation period, the reservoirs in paleohigh are intensively dissolved and represent good reservoir properties, with an average porosity of 14.78% and permeability of 7.849×10-3 μm2. Contemporaneous-penecontemporaneous dissolution results in the formation of most effective pores, which is the key factor for the formation of grain bank reservoirs in the study area.
