【摘要】：气测录井在石油天然气地质勘探中,是主要录井技术手段。目前气测资料主要包括:随钻资料、全脱资料及后效资料。但仍存在4项主要问题:检测手段日益丰富与气测资料应用相对单一的矛盾;钻井工艺飞速发展与气测资料应用水平相对滞后的矛盾;已有的气测应用方法还需进一步完善;已有的气测应用方法还需进一步完善。所以本文主要以油气水层响应特征为基础,依托钻井液对气测检测影响因素校正,明确了气测检测影响的主要因素,创建了钻井液含气量的数学模型,求取及优选了评价参数,结合地化、测井资料,构建了气测资料的评价方法,探索了应用气测资料进行产能预测的方法。经过攻关形成了技术成果,主要包括以下几个方面:1、依据随钻气测资料和全脱气分析资料,研究总结了油层、油气水层、中浅层气层和深层气层的气体组分响应特征及变化规律。2、全面总结了全烃曲线形态,确定了不同异常形态厚度划分方法。3、建立了以组分资料为主——3H法,结合全烃、钻时等资料,识别落实油气显示的方法。4、通过模拟实验,确定了气测资料的主要影响因素,并建立了其校正方法,并首次把逸散气检测纳入到实验中。5、求取了气测资料对油气水层的评价参数并建立了以气测资料为主,结合地化测井资料的评价方法。6、探索了应用气测资料进行产能预测的方法。
[Abstract]:Gas logging is the main logging technique in petroleum and natural gas geological exploration. At present, the gas data mainly include: drilling data, complete stripping data and aftereffect data. However, there are still four main problems: the contradiction between the abundance of detection means and the relatively single application of gas logging data, the contradiction between the rapid development of drilling technology and the application level of gas logging data, the further improvement of the existing gas logging application methods, The existing gas measurement methods need to be further improved. So this paper is mainly based on the response characteristics of oil-gas and water layers, based on the correction of the influence factors of drilling fluid on gas logging detection, defines the main factors affecting gas testing, establishes the mathematical model of the gas content of drilling fluid, and obtains and optimizes the evaluation parameters. Combined with geochemistry and logging data, the evaluation method of gas logging data is constructed, and the method of productivity prediction based on gas logging data is explored. After tackling the key problems and forming technical achievements, mainly including the following aspects: 1. Based on the gas while drilling data and the analysis data of total degassing, the oil, gas and water layers are studied and summarized. The response characteristics and variation law of gas components in medium and shallow gas reservoirs and deep gas reservoirs. 2. The total hydrocarbon curve shape is summarized, and the thickness of different abnormal forms is determined. 3. The 3H method, which is mainly composed of component data, is established, and the total hydrocarbon is combined with the total hydrocarbon. 4. Through simulation experiments, the main influencing factors of gas logging data are determined, and its correction method is established, and the dissipative gas detection is included in the experiment for the first time. The evaluation parameters of gas logging data to oil, gas and water layers are obtained, and the evaluation method based on gas logging data and geochemical logging data is established. 6. The method of using gas logging data to predict productivity is explored.
