Accurate Pressure Management of Parallel Choke Manifold

Abstract:

The conventional valves used in the choke manifold for well control usually have intensely nonlinear characteristic of the match between pressure choking and vale opening. Therefore, it is difficult to achieve the precise choking pressure that is essential to the managed pressure drilling (MPD) through a single throttle within the scope of full opening. However, the parallel choke manifold proposed in this paper, i.e. a program of parallel throttling, can enhance the accurate choking wellhead backpressure for MPD. The fine linear choking principle and feasibility of the parallel choke manifold were analyzed in detail by calculating the resistance modulus of bypass valves. The formula calculated the resistance modulus of each valve under different working state. Furthermore, the laboratory tests shown the parallel throttle method can achieve the control of fine choking pressure by switching one or more valves in the branch pipes. Therefore, the proposed parallel choke manifold system can reduce the requirements for the linear capability of valves and provide some references to further study the surface fine choking pressure system for MPD.
