Gamma ray /Temperature /Casing Collar Locator (CCL) 

SITAN MPGCW43-100D Gamma ray /Temperature /Casing Collar Locator (CCL) logging tool is used to measure the gamma ray, real-time well temperature variation of the underground sections and the depth information of the oil casing collar. The gamma data is obtained by measuring the natural gamma ray of the formation, and the curve can be used to analyze and evaluate the formation geological information. The CCL data is used to detect the position of the collar of oil tubes and casing tubes in the well. The combination of these two data can accurately locate the formation depth of the oil casing. At the perforation position, when the oil is produced in the downhole oil reservoir, since the production fluid comes from the higher oil layer, the temperature data can cause dramatic or abnormal changes, which can be used as qualitatively determine basis to estimate the oil and gas well productivity, output location and other information. SITAN MPGCW43-100D Gamma ray /Temperature /Casing Collar Locator (CCL) logging tool can also be used with other cased hole logging tools, such as multi finger caliper, Magnetic Thickness Tool, Magnetic Thickness Detector etc. to provide oil casing depth information.

 

Feature 


1. Connected with other logging tools such as multi finger imaging tool(MIT), magnetic Thickness Tool (MTT), Gyroscope inclinometer etc. to perform depth calibration for other tools.

2. Adopt special armored high accuracy platinum temperature sensor to guarantees high accuracy, high resolution and high sensitive.

3. Time lag is less than 1s.
