Application of Guargum Separation Repair Technique in Submarine Oil Pipeline

In allusion to repair operation of submarine oil pipeline, guargum separation repair technique is developed. Scenario on guargum separation repair technique is worked out through field investigation, laboratory formulation screening, theoretical calculation and analysis. Field application results show that this technique can effectively prevent environmental pollution induced by oil leaking during submarine pipeline repair and it is of the excellent characteristics of safe, stable and low cost.
