【摘要】 辽河坳陷西部凹陷兴马潜山发现于上世纪70年代,由于受当时技术条件和地质认识的限制,没有近一步深入研究,80年代后期随着三维地震技术的发展及石油能源的紧张,促进了变质岩等特殊岩性油藏的勘探。兴马太古界潜山为孔隙裂缝型储层,储集空间分为孔隙型和裂隙型两大类,主要储集空间类型为构造裂缝和破碎粒间孔、溶蚀成因的孔、缝及结晶成因的孔隙。变质岩储层具有一定的特殊性,储层研究是油藏的勘探、开发的基础。本文利用录井、取心、测井资料从岩石物理研究入手,开展了本区变质岩岩石类型、储集空间类型、岩性测井识别、储层测井识别、储层参数定量解释等方面的研究。从岩矿分析等岩石物理分析入手,通过岩石测井评价机理深入分析,总结归纳各种岩性的测井响应特征,进行定性、定量的判别潜山的岩性。在岩性准确划分基础上,确定储集岩、非储集岩,在储集岩中以试油、试采资料为基础,建立了测井信息与储层特征的对应关系,选用能反映基质孔隙或网状裂缝较好的声波时差及对储层响应特征明显的深侧向电阻率曲线作为储层划分的主要参数,制作了Rlld—Δt交会图版,确定储层定量划分标准。通过开展兴马太古界潜山储层研究,基本搞清了潜山的储层特征及储层分布,为兴马潜山的储量申报、油藏开发提供了依据。更多还原

【Abstract】 The Xingma buried hill was discovered in 1970s. There was no further study because of the technology limitation and the lackness of geology knowledge at that time. The metamorphic reservoir exploration was accelerated by development of 3D seismic technology and the shortage of petroleum in 1980s. The Xingma buried hill is a porous fractured reservoir, consists two types of reservoir space--- pore type space and fracture type space. The main reservoir space types are tectonic fracture, fragmented intergranular space, corrosion formed hole and fracture, crystallizaion formed pore. The metamorphic reservoir is very special, and the reservoir study is the base of exploration and exploitation.Starting with research of petrophysical research based on well logging data, coring data, and wireline well logging data. The essay studies on lithology type, reserve space type, lithology identification, and reservoir identification of metamorphic by logging, reservoir parameters interpreting, etc. While in the reservoir rock the corresponding relationship of logging information and reservoir characteristics can be established on the base of testing and producing test. by selecting acoustic time that is sensitive to the matrix pore or sensitive to ramifying fissures, and by selecting the electric resistivity curve of the deep investigation lateral log that is responded to the reservoir characteristic obviously as major reservoir classification parameters. Then by drawing Rlld—Δt crossplot, the reservoir classification criterion can be confirmed quantitatively.The Xingma Archaean buried hill reservoir parameter and reservoir distribution are ensured by reservoir research, and provide important evidence to reserves report and reservoir development.更多还原
