Abstract: A first water injection into an injection well is carried out followed by a first shut-in of the injection well. A second water injection is carried out, a volume of the injected water exceeds several times a volume of water in the well in an intake interval. Then there is a second shut-in of the injection well, and during the second shut-in transient temperature profiles are registered within the intake interval by temperature sensors. Then a third water injection step is carried out and at an initial stage of the third injection transient temperature profiles in the intake interval are registered using the temperature sensors. The transient temperature profiles registered during the second shut-in period are analyzed and intake zone boundaries are determined. The transient temperature profiles registered at the initial stage of the third water injection are analyzed and a water intake profile is determined.

Abstract translation: 首先注入注射井，然后首先关闭注射井。 进行第二次注水，注入水的体积在进气间隔内超过井中几倍体积的水。 然后，注入井第二次关闭，在第二次关闭过程中，瞬态温度曲线通过温度传感器记录在进气间隔内。 然后执行第三次注水步骤，并且在第三次注射的初始阶段，使用温度传感器登记进气间隔的温度曲线。 分析在第二次关闭期间登记的瞬态温度曲线，并确定进气区边界。 分析在第三次注水初始阶段记录的瞬态温度曲线，并确定进水曲线
