APPARAT SAMT FREMGANGSMAATE FOR REPARASJON AV BROENNER |
摘要 |
<p>Flow channels behind the casing in a well are plugged by detecting a circumferential temperature anomaly on the casing, perforating in the direction of such anomaly, and introducing cement into the perforations. The apparatus for locating and perforating into a flow channel includes a sensitive temperature sensing assembly capable of detecting temperature differences as low as 0.01 DEG F, and an attached perforating gun having a fixed orientation in relation to the temperature sensing assembly.</p> |
