有桿泵抽油井試井理論


摘 要
試井是油氣藏工程的組成部分，它涉及到油層物理、儲層物性、流體性質(zhì)、滲流理論、計算機技術(shù)、測試工藝、測試工藝和儀器儀表、設(shè)備等各個領(lǐng)域，是勘探開發(fā)油氣田的主要技術(shù)手段和基礎(chǔ)工作之一。
為了給油藏綜合治理和制定單井措施提供重要依據(jù)，各油田不斷改進抽油井試井工藝，完善解釋方法。目前主要通過起泵測壓、環(huán)空測壓、液面監(jiān)測和隨泵測壓等方法進行抽油井試井。起泵測壓主要用于測靜壓；環(huán)空測壓受井深、井斜的影響不能大面積推廣；液面監(jiān)測簡便易行, 但折算井底壓力的精度受到泡沫段和油液界面位移的影響；隨泵測壓可準(zhǔn)確地反映井底壓力的波動變化，能夠指導(dǎo)抽油井措施的實施。對井底壓力的折算方法進行了探討，提出要分別確立適合各區(qū)塊的液面折算井底壓力的經(jīng)驗公式和計算方法，同時用環(huán)空實測壓力與液面恢復(fù)方法進行對比驗證其準(zhǔn)確性?，F(xiàn)場實踐證明，準(zhǔn)確的試井資料在油藏動態(tài)分析和油井措施制定中發(fā)揮了重要作用。

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.
