The power consumption for agitating viscoelastic fluids including Boger fluids and Newtonian fluids in the laminar regime were compared for the inner-and-outer helical ribbon-anchor and the four helical ribbon-anchor impellers. The influence of elasticity on power consumption is significant. For Boger fluids the power consumption could be up to 1.5 times of that fro Newtonian fluids.The power consumption correlations:for agitating Newtonian, pseudoplastic and viscoelastic fluids was developed by means of a second-order...

The migration mechanism of detritus in an annulus is so different from that in a verticle wellbore,and so it turns more and more difficult to carry detritus. The effection on carrying detritus in horizontal well drilling of the rheological parameters in three well-flushing zones(the first is in the area of0°~30°;the second is 30°~ 60°;the third is 60°~ 90°)is briefly summerized. Special requirements and reasonable range determination method for the rheological parameters in these three zones are both proposed....

The migration mechanism of detritus in an annulus is so different from that in a verticle wellbore,and so it turns more and more difficult to carry detritus. The effection on carrying detritus in horizontal well drilling of the rheological parameters in three well-flushing zones(the first is in the area of0°~30°;the second is 30°~ 60°;the third is 60°~ 90°)is briefly summerized. Special requirements and reasonable range determination method for the rheological parameters in these three zones are both proposed. Through statistical analysis on data of nine highly deviated wells and horizontal wells in Shengli and Dagang Oil Fields, a reasonable range of drilling fluid rheological parameters is shown out.

在水平井钻井过程中,岩屑在环空中的运移机理与垂直井眼相比存在明显差异,携带岩屑也变得越来越困难。本文运用理论研究成果,对水平井钻井中钻井液流变多数在三个洗井区(第一洗井区0°~30°,第二洗井区30°~60°,第三洗井区60°~90°)的携带岩屑效果影响进行了概述,提出了三个洗井区对钻井液流变参数的特殊要求以及定性地确定钻井液流变参数合理范围的方法。最后根据胜利油田和大港油田的9口大斜度井以及水平井的资料,进行统计分析,给出了能获得良好携带岩屑效果的各洗井区钻井液流变参数的合理范围。

For avoiding domnhole problem,control of surge presssure resulting from running or pulling a pipe in a boreholefull of drilling fluid is an important factor in drilling design and practice, and the methods which are used for predicting surgepresssure should be more accurate. The traditional computational errors need to be corrected.In this paper,an accurate model predicting steady surge pressure resulting from running or pulling a pipe in a vertical wellbore has been developed on thebasis of Herschel-Bulkley rheological model. Simple working formulae and graphs for computation are also given,which canbe used for determined surge pressure,safety maximum tripping velocity and also the drilling fluid rheological properties inthe field.

赫谢尔-巴尔克莱(Herschel—Bulkley)流变模式是一个三参数模式,因其精度较高,近几年国内多用其描述钻井液的流变性。不过,与该模式相应的有关钻井水力学方面计算模式并不完善,影响了该模式的推广使用。本文以该模式为基础,从理论上推导并建立了直井起下钻或下套管过程中稳定层流条件下钻井液粘性产生的波动压力计算模式──—赫谢尔-巴尔克莱液体稳态波压模式。给出了有关计算公式和图表。本文为更准确地计算起下钻或下套管等钻井作业过程中井内产生的波动压力提供了理论依据。
