- To resolve the problem, based on backpressure test theory and superposition principle, this paper designed a new test method, named Backpressure Isochronal Test. 以回压试井理论和渗流叠加原理为基础,提出了"回压等时试井"产能评价方法,该法所需测试时间与"单点法"大致相同,但能较准确地评价低渗气井产能。
- There are two defects in the analysis method of the conventional modified isochronal test data, especially in the low permeability gas well with small control reserve of a single well. 对于单井控制储量比较低的低渗透致密储集层气井,传统修正等时试井分析方法的不足是:二项式系数偏小甚至为负,稳定点的确定没有完全按定义进行。
- Nowadays, the main method of determining oil and gas well deliverability is steady well test, that is back-pressure testing, isochronal testing, revisionary isochron test and single-point test. 目前确定油、气井产能的主要方法是稳定试井方法,即回压试井、等时试井、修正的等时试井和一点法试井。
- By superposition principle, the theoretical deduction to modified isochronal testing data drives a linear relationship equation. 采用叠加原理,对修正等时试井数据进行理论推导,得出直线关系式;
- Conventional application of modified isochronal testing is mainly to determine the current open flow capacity of the gas well,and thus making a reasonable working system. 修正等时试井的传统应用,主要确定气井当前无阻流量,进而制定合理工作制度。实际上,还可以根据延续生产动态资料,分析气井生产动态特征,评价稳产水平和能力;
- A new analysis method of modified isochronal test data 修正等时试井资料分析新方法
- Aiming at the character that gas well isochronal testing consists of many drawdown and build-up cycles, the flowing and build-up pressures are regarded as contunuous action process. 针对气井等时试井一般由多个开关井测压周期组成的特点，将每个测压周期流动压力和恢复压力看成是连续作用过程。
- A simple test will show if this is real gold. 简单的试验就能证明这是否是真金。
