摘要

为更好监测油气藏生产动态,提升油气田试井产能,梳理了4种常用不稳定试井技术的原理、解释方法及应用效果,分析了不稳定试井技术存在的问题,并提出了未来的重点攻关方向。结果表明:目前常用的不稳定试井技术主要存在井间干扰现象严重、试井曲线特征复杂、试井解释准确率低且复杂断块油藏常规试井效率低和损耗大等问题;数值试井、垂向干扰试井及低频脉冲试井等新型试井技术可解决常规不稳定试井技术存在的问题;不稳定试井技术下步发展趋势是深层超深层测试工艺、低渗致密储层测试资料评价、压裂效果评价及资料的综合应用等方面,可着重于数值试井、多分层试井等方面的技术攻关。通过对不稳定试井技术的综合剖析,可对现场测试提供技术参考,并为后续技术发展提供新视角。

Abstract

In order to better monitor the production performance of oil and gas reservoirs and improve the production capacity of oil and gas fields, this paper reviews the principles, interpretation methods, and application effects of four commonly used transient well testing technologies. It analyzes the problems existing in transient well testing technology and proposes future key research directions. The results show that the currently commonly used transient well testing technologies mainly suffer from serious inter-well interference, complex characteristics of testing curves, low accuracy of testing interpretation, and low efficiency and high losses in conventional testing of complex fault block reservoirs. While new types of testing technologies such as numerical well testing, vertical interference testing, and low-frequency pulse testing can address these issues. The future development trends of transient well testing technology lie in deep and ultra-deep testing processes, evaluation of low-permeability tight reservoir testing data, assessment of fracturing effects, and integrated application of data. Emphasis can be placed on technical breakthroughs in numerical well testing and multi-layer testing. Through a comprehensive analysis of transient well testing technology, this study can provide technical references for on-site testing and offer new perspectives for subsequent technological developments.

Key words： transient well testing; pressure buildup testing; pressure drawdown testing; interference testing; pulse testing
