摘要/Abstract

摘要： 伊拉克哈勒法耶油田Mishrif组滩相储层发育，是研究区内最主要的产油层位。利用岩心、薄片、测井资料对Mishrif组沉积相进行了研究，结果表明该组发育局限台地、开阔台地、台内洼地和台地边缘4种沉积相，滩相储层主要发育在开阔台地和台地边缘相带。并综合利用铸体薄片、物性实验数据及压汞曲线等资料对滩相储层特征和成因进行了分析。滩相储层岩石类型多样，发育生屑灰岩、生屑泥粒/粒泥灰岩、砂屑灰岩等多种岩石类型，岩石颗粒较粗。孔隙类型多样，主要以铸模孔、粒间孔、溶孔和体腔孔为主，其中以粒间孔和铸模孔发育最为广泛。各类滩相储层孔隙度较高，渗透率差异明显，平均渗透率为（2.35~139.17）×10^-3μm²。整体孔隙结构较好，排驱压力较低，大喉道较为发育。滩相储层发育受沉积环境控制和成岩作用改造程度影响，有利的沉积条件是滩相储层原生孔隙发育的基础，同生期溶蚀作用的改造形成大量次生孔隙，从而提高了储层的储集性能。

Abstract: The Mishrif Formation in the Halfaya oilfield of Iraq develops shoal facies reservoir, and it is one of the main producing horizons in the study area. The Mishrif Formation sedimentary facies has been studied using the data of core, thin section and well logging. The result shows that four types of sedimentary facies are developed in the Mishrif Formation, which are restricted platform, open platform, intra-platform and margin platform. The shoal facies reservoirs are developed mainly in the facies of open platform and margin platform. Casting thin sections observation, physical experiment, and mercury injection are conducted to study the characteristics and genesis of shoal facies reservoirs. A shoal facies reservoir has multiple types of rocks, including bioclast limestone, bioclastic packstone/wackestone and calcarenite etc., and the rock particles are thicker. The pore types are various, mainly in the form of moldic pore, intergranular pore, dissolved pore and visceral foramen, of which intergranular pore and moldic pore development are the most widespread. To all kinds of shoal facies reservoirs, the porosities are higher, the permeabilities differ distinctly with the average permeability at (2.35~139.17) ×10^-3 μm². The overall pore structure is relatively good, displacement pressure is low, but large throats are developed. The development of shoal facies reservoirs is controlled by the depositional environment and diagenetic transformation degree influence. A favorable sedimentary condition is the foundation of the shoal facies reservoirs development, and syngenetic period dissolution modification improves the reservoir properties, so that it become a high quality reservoir.
