Study of reliability of block automated process units
The paper shows that the proposed generalized index of reliability of the system of block automated oilfield equipment characterizes the relative amount of production loss and has the advantage that it is independent of a well flow rate and makes it possible to compare the reliability of the systems with different flow-rates. Such index as equipment failure, which is defined as an event of its integrity violation leading to production loss is discussed. Loss of oil products is unacceptable in view of environmental protection, and can be regarded as a rare event with catastrophic consequences. In this regard, the collection of statistical data on oilfield equipment failures in the Far North conditions is rather difficult. However, even in these conditions, the estimated calculations of the level of the process equipment reliability should be carried out.
