兴隆台太古界变质岩潜山储层测井评价研究
|
摘要
兴隆台潜山带经历了多年勘探后,仍存在许多尚需深入探讨的关键问题,这些问题的解决必须建立在大量细致工作的基础上,结合近年来潜山油藏勘探开发比较成熟的新技术、新理论和新方法,以全面、独特的视角重新认识和总结低潜山石油地质规律,以期建立一套具有辽河特色的变质岩潜山勘探技术方法系列。本文主要以潜山内幕油气成藏主控因素为主线,根据实际勘探现状,针对潜山岩性复杂、裂缝发育不清、有效储层识别难度大等不利因素,有重点地开展深入细致的研究。取得了如下研究成果:
本文运用地震、地质、测试及分析化验等各种资料,研究潜山油藏地质特征,重点建立兴隆台潜山带储层岩性识别、储层识别、裂缝特征和储层参数解释标准和模型,确定储量计算的有效厚度、有效孔隙度等各项参,取得了如下研究成果:
通过兴隆台潜山带综合地质特征研究认为,太古界潜山储集岩以黑云斜长片麻岩为主,同时存在混合花岗岩、中酸性的岩浆岩储层。储集空间以碎裂孔隙以及宏观构造裂缝、微观构造裂缝为主。储层物性特征表现为中低孔-低渗储层。
从太古界潜山岩石测井响应机理研究入手,根据岩石薄片和X-衍射全岩分析结果确定太古界潜山岩石主要造岩矿物,根据各造岩矿物测井特征值的差异,选择对岩性敏感的自然伽玛、密度、中子、光电吸收截面指数等测井曲线作为岩性识别的主要手段,建立太古界岩性定性识别方法和储集岩定量划分标准,效果较好。
以岩石薄片和X-衍射全岩分析确定的太古界潜山岩石五种主要造岩矿物(石英、钾长石、斜长石、黑云母、角闪石)和对岩性及储层反映敏感的密度、中子、时差曲线作为基础,在制定出主要岩性识别曲线特征的情况下,探索完成了该区成像测井资料的处理和解释,建立了利用常规及声电成像测井进行裂缝评价及有效厚度划分的方法,为储层综合评价奠定了坚实基础。
Although with many years of exploration in buried hill zone of Xinglongtai area, there are still a number of problems needed to be studied intensively. On the basis of large amounts of detailed work, with relatively mature newly-developed techniques,theories and methods on buried hill, petroleum geology of low buried hill is recognized and summarized again from comprehensive and unique perspectives in order to develop a series of exploration technique with characteristics of Liaohe Oilfield. This paper focuses on key factors of hydrocarbon accumulation in inner buried hill. According to practical exploration situation, with regard to complexity of lithology, indistinctness of fracture development and difficulty in effective reservoir identification, in-depth research is proceeded with emphases. Following results are obtained:
Geologic characteristics of buried hill reservoir are studied using data of seismism, geology, testing and analysis etc. Emphasis is put on establishing standards and models for lithology discrimination, reservoir identification, fracture characteristics and parameter interpretation for buried hill in Xinglongtai area to determine various parameters such as net pay thickness and effective porosity etc for calculating reserves.
According to comprehensive geologic characteristics of Xinglongtai buried hill zone, Archaean buried hill reservoir is mainly composed of biotite plagioclase gneiss, containing migmatitic granite and intermediate acidity igneous rock. Reservoir space mainly consists of disrupted pore, macrostructure and microstructure fractures. Reservoir rock exhibits medium low-low permeability.
Starting with log response mechanism in the study for Archaean buried hill rock, principal petrogenetic minerals are identified based on thin section and X-diffraction bulk-rock analysis. According to differences in characteristic logging values of various petrogenetic minerals, gamma ray, density, neutron and photoelectric cross-section index logs are adopted as the main way of lithology discrimination. Qualitative identification method for Archaean lithology and quantitative division standard for reservoir rock are established. And relatively good result is obtained
On the basis of the five principal petrogenetic minerals (quartz, potassic feldspar, plagioclase, blotite and amphibole) of Archaean buried hill rock determined by thin-section and X-diffraction bulk-rock analysis as well as density, neutron and moveout logs sensitive to lithology and reservoir, main log characteristics for lithology discrimination are formulated. Processing and interpretation of imaging log data for this area are completed. The method for fracture evaluation and effective thickness division is developed using conventional and acoustoelectric imaging logs. This lays a solid foundation for comprehensive evaluation of reservoir
