Shallow water cluster well mouth skid-mounted production system

Abstract

The invention discloses a shallow water cluster well mouth skid-mounted production system. The shallow water cluster well mouth skid-mounted production system comprises bottom skids, permanent guide base discs are installed at the positions, at an oil field well mouth, of the bottom skids, the bottom skids are provided with Christmas trees fixedly connected with the permanent guide base discs through guide columns in a guiding mode, an underwater distribution unit assembly composed of a hydraulic distribution box, a power distribution box and a control distribution box is arranged on one sideof the bottom skid; and collecting pipes and output pipes are arranged at the side ends of the Christmas trees, the collecting pipes are in communication with the Christmas trees through branch Christmas pipes, the collecting pipes are in communication with the output pipes through conveying pipes, the output pipes and the collecting pipes between the adjacent Christmas trees are fixed through connecting flanges, gate valves are arranged on the conveying pipes, and gate valves are arranged at the output end of the collecting pipes; and an output interface is arranged at a port at the tail endsof the output pipes. The cluster well mouth skid-mounted production system is suitable for oil field group exploitation in a shallow water sea area, low in cost and convenient to manage in a unifiedmode.

Description

technical field [0001] The invention relates to the technical field of marine shallow water production systems, in particular to a skid-mounted production system for shallow water cluster wells. Background technique [0002] Since the late 1980s, the exploration and development of deep-sea oil and gas resources has accelerated. The international definition of deep water is 200-1500m. The geographical location is special, or it is located in a sensitive area, or it is far away from the surrounding supporting facilities. For oilfield group areas with a water depth of less than 200m, if the "deepwater development model" is also used for the design of the underwater control system, it will inevitably result in waste of investment. With the maturity of domestic cluster well drilling technology, cluster horizontal well technology has the advantages of less investment, quick results, and convenient unified management. It is widely used especially on offshore platforms and is an ef...
