Memory Multi-parameter Production Logging Technique

Introduced are logging principle, global development status and application of the memory multi-parameter logging technique. It is a new kind of logging technique developed in recent years, which can solve the logging problems that could not be resolved by conventional wireline logging. Compared with conventional wireline logging technique, the memory logging technique has advantages such as low cost, adaptability to abominable environment in wells, small space requirement and simple field operation. Field log application indicates that the memory multi-parameter logging has the same ability as wireline logging. It is adaptable to log operations in oil and water wells in complex environments, including steam entry profile log in heavy oil high temperature and high pressure steam injection wells, water entry profile log in high pressure closed water injectors and the evaluation of high pressure fractured wells, which can not be performed with conventional wireline logging techniques. With the development of memory production logging techniques and supporting equipment, the memory logging techniques will be applied extensively.
