国外试井技术进展评述

Review of Technical Progress for Well Testing in Abroad

重点介绍了(1)国外试井技术从1987年至1991年的发展的现状,特别是在双对数的压力和压力导数典型曲线应用的基础上,提出新的压力函数(压力导数化函数、压力积分函数、压力积分导数函数、积分压力导数函数等)所组成的典型曲线。它既改进了求导和拟合方法,又不丧失压力导数所显示的特征。还叙述了流量压力新函数、非自喷井试技术和人工智能技术。(2)国外试井技术中软环境科学发展动向,如强化诊断、抽油井试井的发展重点。

Current situation of development of well testing techniques in abroad from 1987 to 1991 were mainly represented,especialy on the basis of type curve application of log-log pressure and pressure derivatives, type curves consisted of new pressure functions (pressure derivative,pressure integral and integral pressure derivatives,etc.) were given, It improves not only the method of derivative calculation and matches, lint also can not lose the displaied characterization of pressure derivatives, and new function of pressure of flow rate, nionflowing well testing and artificial intelligence were described as well. Soft enviromental science in well testing techniques in abroad,such as strengthen diagnosis and developing main point of well testing in pumping well was also represented.
