【摘要】：天然气是一种高效、清洁的能源,无论是从国内看,还是从整个世界范围内看,它的地位越来越重要。在我国,已经探明天然气储量越来越丰富,天然气工业发展也日益蓬勃。但是,天然气作为一种不可再生的资源,它的储量在我国也是有限的,所以如何合理高效的开发好天然气田是目前的一个主要任务。气藏动态分析贯穿整个天然气田开发过程中的始末,并涉及到方方面面。研究其动态特征、掌握其变化规律是认识天然气田的最主要也是最基本的工作。随着计算机科学技术的发展,在其他行业的交叉应用也越来越广泛。在天然气田开发过程中引用计算机分析的方法,给庞大的生产数据的处理和分析带来了巨大的便利,用计算机对天然气田进行气藏动态分析将更加高效、准确。针对传统软件的不足,研究项目主要研究重点是在于动态地进行分析和预测。其中,包括天然气的物理性质分析及井底压力的折算,涉及的方法有四种。储量的计算研究如何提高动储量计算的精度,重点研究了压降曲线法及其改进的方法,递减分析对比研究了指数递减、调和递减和双曲递减三种递减方式的特点,预测分析模型对比研究六种模型及其适用范围。通过对天然气田大量实验数据的分析和多种方法的对比研究,了解和掌握气藏开发过程中的动态规律。根据这些规律和动态分析的结果,可以帮助我们制定合理的开发方案、编制可行的生产规划,从而为科学地调整开发好天然气田提供简捷实用的工具。
[Abstract]:Natural gas is a kind of efficient and clean energy, its status is becoming more and more important both from the domestic point of view and from the whole world. In our country, the proven natural gas reserves have become more and more abundant. The development of natural gas industry is also booming day by day. However, as a kind of non-renewable resource, natural gas reserves are also limited in our country. So how to develop natural gas field reasonably and efficiently is a main task at present. Gas reservoir performance analysis runs through the whole process of natural gas field development, and involves every aspect. It is the most important and basic work to understand the natural gas fields. With the development of computer science and technology, The cross-application in other industries is becoming more and more extensive. The use of computer analysis in the development of natural gas fields brings great convenience to the processing and analysis of huge production data. It will be more efficient and accurate to use computer to analyze gas reservoir performance in natural gas field. In view of the shortage of traditional software, the main research focus of the research project is to analyze and predict gas reservoir dynamically. Including the analysis of physical properties of natural gas and the conversion of bottom hole pressure, there are four methods involved. The calculation of reserves how to improve the accuracy of calculation of dynamic reserves, the pressure drop curve method and its improved method are emphatically studied. The characteristics of exponential decline, harmonic decline and hyperbolic decline are analyzed and compared. Comparative study of six kinds of models and their applicable scope. Through the analysis of a large number of experimental data and the comparative study of various methods in natural gas fields, To understand and master the dynamic laws in the process of gas reservoir development. Based on these laws and the results of dynamic analysis, we can help us to formulate reasonable development plans and prepare feasible production plans. Thus, it provides a simple and practical tool for scientific adjustment and development of natural gas fields.
