摘要

渐新统—中新统库姆组海相碳酸盐岩是伊朗卡山地区目前最有利的一套储层,且已获得了高产工业油气流。通过钻井、测井、地质、地球物理等方法,对这套储层进行了系统的研究和评价,结果发现,库姆组储层以台地相生物灰岩为主,有效储集空间为溶孔和裂缝,孔隙类型是裂缝+孔隙型,具有双重介质特征。利用地震属性分析、波阻抗反演等方法,对库姆组有利储层的分布进行了平面上的预测,发现有利储层主要分布在断裂、构造发育部位和褶皱的转折端,但平面上和垂向上都具有强非均质性,认为沉积环境、成岩作用和构造活动是控制该区储层发育的3个主要因素。

Abstract

There are 4 sets of potential reservoirs in the Kashan area in Iran, among them the carbonate reservoir of Qom Formation in Oligocene Miocene is the most favorable one, and high commercial oil and gas flow was yielded from it. According to drilling, logging, geology, geophysics etc, the reservoir is comprehensively studied and evaluated. Some knowledge is gained as followings: bioclastic limestone in the carbonate platform is the main rock type. Valid pores are solution pore and fracture, pore type is fracture+proe, having double medium feature and serious heterogeneity. According to sedimentary facies and diagenesis, reservoir physical characters are better in well Arn1, Arn2, Arn3 than in well Fkh1, for fractures are not developed and cemented by shale seriously in the latter. The sedimentary environment of the Qom Formation is turbid water carbonate platform. Grain shoal, bioclastic shoal and point reef are the most favorable locations for valid reservoirs. Sedimentary environment, diagenesis and tectonic movement are the controlling factors of reservoir development.
