轻烃分析技术在油气勘探开发中的应用
摘要
本文综合采用石油地质学、有机地球化学等的最新理论和方法,以测井、录井资料为基础,结合密闭取芯、岩芯分析等分析资料,对轻烃分析技术在油水层识别、水淹层评价进行了深入细致的分析和研究。
通过开展大量的基础实验,建立和完善轻烃分析方法。采用RTL技术,实现了轻烃组分的自动定性分析。全面系统地研究了储层烃类主控因素及与油水层的关系,创新性的求取、优选轻烃的评价参数;将烃源岩指标及烃类的蚀变作用引入储层评价,创建了依据生物降解强弱分别建立储层含水性的轻烃识别方法,提高了油水层的判准率。分别建立了古龙凹陷葡萄花油层、三肇凹陷葡萄花油层、东西部扶杨油层、海拉尔盆地贝尔凹陷-乌尔逊凹陷南二、一段含水性判别图版。
本文存在着特殊性,以往没有开展过应用轻烃分析技术识别油水层方面的研究,这项技术用于油水层识别是近年来国内新兴的技术,没有成熟的应用方法。有很多内容需要攻关研究,如轻烃取样材料、方法、组分自动定性、评价参数的求取、优选及油水层评价方法等方面。基于油田生产实际的需求,本文一边攻关研究、一边在试验应用中逐步改进完善,而且与生产紧密结合,两年来在探井及油藏评价中推广应用轻烃分析137口井,已试油74口井154层,判准140层,判准率为90.9%。两年来的实践证明,轻烃分析技术在油水层识别上具有明显的技术优势,这项技术的推广应用,较大的提高了录井的解释评价水平,具有十分广阔的应用前景。
Based on the datum of logging and well logging, combing with the information of pressure coring and core information, this paper analyzes and studies the application of light hydrocarbon analysis in distinguishing oil-water bed and evaluation method of water flooded layer by using recent theory and method of petroleum geology, organic geochemistry.
The method of light hydrocarbon analysis is established and improved according to doing a mount of basic experiment. The automatic qualitative analysis of light hydrocarbon components is achieved adopting CRT technology. This paper studies the reservoir hydrocarbon master control element and the relationship to oil-water bed completely and systematically, and gets and optimizes the evaluation parameters of light hydrocarbon creatively. The light hydrocarbon recognition method of reservoir aquosity in the light of biodegradation strong and weak is created by taking the source rock target and hydrocarbons alteration into reservoir evaluation, by which the distinguish rate of oil-water bed is raised. The aquosity distinguish board to Putaohua Reservoir in Gulong Sag, Putaohua Reservoir in Sanzhao Sag, Fuyang Reservoir in east and west of Daqing Placanticline and Nantun Formation of Beir-Wuerxun Sag in Hailaer Basin are established.
In this paper, a particularity is existed. In the past, there is no research about the application of light hydrocarbon analysis technology to identify water/oil layer. And this technology used to identify water/oil layer is a domestic emerging technologies in recent years, so it has no mature applications. There are many research needed to storm a strategic pass, for instance, sampling materials, methods of light hydrocarbon, automatic component characterization, obtaining and optimization of evaluation parameters, evaluation method of oil/water layer. Based on the actual productive demand of oilfield, this paper does some researches to breach the roadblock, at the same time, gradually improve and perfect in the process of test applications, and the research is closely integrated with production. In the past two years, there are 137 wells that are applicated in light hydrocarbon analysis, including the prospecting wells and reservoir evaluation wells, and 74 oil wells are tested, including 154 layers, in it, 140 layers are tested right, so precision ratio is 90.9%. Over the past two years, it shows that the light hydrocarbon analysis technology in the identification of water / oil layers has a clear technological advantage, as a result, the popularization and application of this technology can greatly improve the interpretation and evaluation level of the logging, that is to say, it has very broad application prospects.
