引言在地层测试中,对于油水同出的非自喷层需要确定测试管柱内原油的回收量,现场上经常用的方法或者是反洗测试管柱或者是通地起管柱确定的原油油柱高度求得原油回收量。这两种方种有其直观的优点、但反洗管柱求原油回收量费时、费力并且不安全、不准确,由起管柱求原油回收量,往往受到各种条件限制,例如,用已试过油层的油管进行测试,就不能应用此方法。本文针对这些问题提出了一种通过计算公式求得管柱内原油回收
INTRODUCTION In formation tests, the non-self-ejec- tive layer for oil and water needs to determine the amount of recovery of crude oil in the test column. Methods commonly used in the field are either backwash test pipe or crude oil Column height obtained crude oil recovery. Both types of square have their intuitive advantages, but the recovery of crude oil from backwashing columns is time consuming, laborious and unsafe and inaccurate. The amount of crude recovered from the column is often limited by various conditions, for example, Tested oil tubing for testing, you can not apply this method. In this paper, a solution to these problems is proposed by calculating the formula to obtain the recovery of crude oil within the column
