High Temperature Memory Production Logging Tools

SITAN MP32-250 250℃ high temperature Memory production logging tools is mainly used for performing the logging tasks in high temperature production wells during the process of oil production and development in oilfield. The 250℃ high temperature Memory production logging tools can be widely used in logging tasks onshore and offshore with working conditions that well temperature is not more than 250 ℃ (250 ℃ 2 hours, 175 ℃ 4 hours) and the pressure is not higher than 60 Mpa .

SITAN 250℃ high temperature Memory production logging tools can measure the 5 parameters including: the casing collar, fluid temperature, pressure, flowrate and water holdup.

SITAN 250℃ high temperature Memory production logging tools provides the dynamic formation information of heat production wells, determining the oil well production condition, monitoring regional area. At the same time, the 250℃ high temperature Memory production logging tools also can be used to examine the effects of various production increasing measures.



SITAN high temperature Memory production logging tools instrument consists of two parts:

Section No.1 includes pressure, temperature, and CCL.

Section No.2 can measure the flowrate and water cut, using the two heat insulation barrels.


Features

1. Max. working temperature: 250 ℃.

2. High temperature cloth umbrella flow-concentrating flow measurement, suitable for small production wells.

3. High sensitivity temperature sensor, time lag is <0.8s.

4. Single core cable logging.
