Cementing anchor plays an important role in prestressed cementing technology of heavy oil thermal recovery. For there are many problems of other anchor: undrillable structure, not to be satisfied the requirements of continue drilling or deepening old well, the authors have designed a drillable anchor. By the way of using finite element analysis, them obtained that the initial angle 38-40° was the best angle for eating into the formation; verified the intensity of anchor-pin system. Through cycling test, them verified the reliability of the anchor; obtained the curves of flow coefficient and the press differential with different nozzle. The analysis and experimental results is very important in guiding significance to optimize the design of the anchor and prestressed cementing operation.
