【摘要】：随着天然气用量的不断增加,对气井产量的要求也就越来越高。天然气不断的开采使得地层压力也在不断的降低,同时,开采难度也越来越大。国内外专家在气井产能的技术方面做了大量的研究,得到了非常可观的成果。气井产能是描述气藏储层性质的一个重要指标,是对储层开发潜力的一个有利评价。当前的首要任务,是如何能够更有效地进行气田动态监测和解释评估研究工作。比如,在天然气生产管理过程中,重点关注气田的动态监测,通过相关的静态数据的采集、分析,满足信息需求和动态分析的需要,为气田的合理开发提供有力的依据,以达到准确的了解、开发气藏的目的,要加强在求取无阻流量和井控储量、气井测试合理关井时间这些方面的应用。产能试井测试技术是气田开发动态监测的一个重要手段。试井技术人员要解决的最迫切的问题,是通过分析测试数据来解决复杂的地质条件问题,也就是气田开发问题,或者如何使用井测数据来诊断气田开发之间的矛盾,这已成为测试数据的有效应用手段。因此,严峻的发展形势对气井的产能试井带来了新的挑战,同时也带来了难得的发展机遇,测试技术也将在继续解决矛盾发展的同时,逐步的发展和改善。本文总结了产能试井即生产能力测试技术的发展过程,以长岭气田为例,研究了气田开发过程中测试数据的实际应用,分析了气田开发过程中不同生产情况的测试数据的指导作用。同时通过对一点法公式的剖析,找出影响无阻流量计算结果的主要参数为产能系数α,并对其进行修正,修正后的产能系数带入一点法的理论公式,得到新的长岭气田的一点法经验公式。通过误差分析,并结合地质及现场情况,得到结论,即新公式所计算的无阻流量更加符合长岭气田实际情况。
[Abstract]:With the increase of the amount of natural gas, the gas production requirements are increasingly high. The exploitation of natural gas to make the formation pressure has been reduced, at the same time, mining has become increasingly difficult. Domestic and foreign experts have done a lot of research on gas production technology, has been very impressive results. Gas well productivity is an important index to describe the nature of the gas reservoir, is a reservoir potential favorable evaluation. The first task, how to more effectively work gas dynamic monitoring and interpretation evaluation research. For example, in natural gas production in the process of management, dynamic monitoring of gas field focus through the static, the data collection and analysis, to meet the needs of information demand and dynamic analysis, provide the basis for the reasonable development of the gas field, in order to achieve an accurate understanding of the development of the gas reservoir in order to strengthen. To calculate the open flow and well controlled reserves, well time these aspects of the application of reasonable close gas test. Productivity well testing technology is an important means of development of dynamic monitoring field. The most urgent problem to be solved well testing and technical personnel, is to solve the problem of complex geological conditions through the analysis of the test data, it is gas field development problems, or how to use well logging data to diagnose the contradiction between gas field development, it has become an effective means of using test data. Therefore, the grim situation of gas well deliverability test has brought new challenges, but also brought a rare opportunity for development, testing technology will also continue to solve the contradiction of development at the same time, the gradual development and improvement. This paper summarizes the development process of the production capacity of deliverability testing and testing technology, Changling gas field as an example, the test data in the process of gas field development The actual application, analyzed the directive function test data of different production conditions in the process of gas field development. At the same time, through the analysis of a formula, the main parameters to find out the influence of calculation results of non resistance flow capacity coefficient, and the modified theoretical formula of modified deliverability coefficient into one point method. By the empirical formula of the new Changling gas field. Through error analysis, and combined with the geological and site conditions, get the conclusion that the new formula, the calculated flow is more consistent with the actual situation of Changling gas field.
