摘要
为提高塔里木富满油田超深井油气藏温度测试精度,通过实例总结了不同类型压力计、不同测试工艺、不同地层流体以及流、静温测试对温度的影响,分析了不同情形下停点温度变化量的差异性,提出了温度过深补偿测试方法,实现了测试现场根据温度的变化趋势及时调整深度对温度变化量进行补偿,形成较稳定的温度梯度。温度过深补偿测试方法已在现场成功应用十几口井,所测温度梯度基本稳定,提高了每个停点温度精度,得到了较好的效果。该方法对分析深井井筒相态分布具有实用价值,对富满油田精准开发具有重要意义。
To enhance the accuracy of temperature testing in ultra-deep wells within the Fuman oilfield of the Tarim basin,by analyzing practical cases,the influences of various factors on the tested temperature were summarized.These factors include different types of pressure gauges,well testing technologies,formation fluids,flowing temperature measurement,and static temperature measurement.In addition,the variations in temperature change at different depth intervals were analyzed,and an over-depth compensation method for temperature testing was proposed.This method enables real-time compensation for temperature fluctuations during field operations by dynamically adjusting depth based on observed temperature trends,thereby facilitating the establishment of a more stable temperature gradient.This over-depth compensation technique has been successfully applied in over ten wells on site,where the measured temperature gradients remained stable and the temperature accuracy of each depth point was improved,achieving favorable results.This method is of practical value for analyzing the phase behavior within the deep wellbore and is of significant importance for the precise development of the Fuman oilfield.
