专利汇可以提供Blowout and lost circulation detector专利检索,专利查询,专利分析的服务。并且A method and apparatus for rapidly detecting blowouts and lost circulation in a drilling well, having particular application to a well being drilled at sea from a floating drilling platform. The return rate of flow of drilling fluid which will be affected by a blowout is monitored and transduced into an electrical signal proportional thereto. The magnitude of the electrical signal is monitored and accumulated over selected overlapping intervals of time to form a sequence of accumulated values. Each accumulated value in the sequence is compared with at least one of the previous accumulated value in the sequence and the difference therebetween determined. This difference is compared with preselected values denoting the allowable limits of the return flow rate of the fluid. If the difference between the accumulated values exceed the preselected values, an indication is provided of the commencement of a blowout or lost circulation. This abstract is not intended to define this invention which, of course, is measured by the claims, or to be limiting in any way as to the scope of this invention.,下面是Blowout and lost circulation detector专利的具体信息内容。
