有杆泵抽油井试井理论


摘 要
试井是油气藏工程的组成部分，它涉及到油层物理、储层物性、流体性质、渗流理论、计算机技术、测试工艺、测试工艺和仪器仪表、设备等各个领域，是勘探开发油气田的主要技术手段和基础工作之一。
为了给油藏综合治理和制定单井措施提供重要依据，各油田不断改进抽油井试井工艺，完善解释方法。目前主要通过起泵测压、环空测压、液面监测和随泵测压等方法进行抽油井试井。起泵测压主要用于测静压；环空测压受井深、井斜的影响不能大面积推广；液面监测简便易行, 但折算井底压力的精度受到泡沫段和油液界面位移的影响；随泵测压可准确地反映井底压力的波动变化，能够指导抽油井措施的实施。对井底压力的折算方法进行了探讨，提出要分别确立适合各区块的液面折算井底压力的经验公式和计算方法，同时用环空实测压力与液面恢复方法进行对比验证其准确性。现场实践证明，准确的试井资料在油藏动态分析和油井措施制定中发挥了重要作用。

Abstract
Well testing is an integral part of oil and gas reservoir engineering，It involves physical reservoir、reservoir properties、fluid properties、 percolation theory、computer technology、 testing technology、test technology and instrumentation、equipment and other fields，oil and gas field exploration and development is the main technical means and one of the basic work.
In order to provide important basis for comprehensive management of reservoir and making single well measurement, National Oil field is improving testing techniques and its interpreting method of pumping well. At present, Pump well is tested mainly by such methods lifting pump pressure measuring mainly used in static pressure measuring, annulus pressure measuring which is no large extension influence by depth and deviation of well, liquid level pressure measuring which is simple and easy but having the effect of foam section and shift of oil2fluid interface on precision of calculating bottom hole pressure , follow pump pressure measuring which can reflect fluctuation change of bottom pressure and instruct implementation of pump well measures, and so on. By analysis on calculation of bottom well pressure, it concludes that, empirical formula and calculation method of calculating well bottom pressure of liquid level suitable for every block should be established and compared with methods of annulus measured pressure and liquid level recovery to validate its accuracy. Field practice p roves that, accurate testing dates play an important role in reservoir dynamic analysis and oil well measure smoking.
