Abstract

A high-sulfur-resistant zipper-type fracturing split manifold for a continuous drilling system, comprising a base, a manual gate valve, a hydraulic gate valve, a fracturing four-way, a hydraulic gate valve, a manual gate valve, a double-flange short pipe, a hydraulic gate valve, and a hydraulic gate valve. Split nine-way, manual gate valve three, hydraulic gate valve three, manual gate valve four and hydraulic gate valve four, manual gate valve one, hydraulic gate valve one, fracturing four-way, hydraulic gate valve two, manual gate valve two, double flange short pipe , Fracturing nine-way, manual gate valve 3, hydraulic gate valve 3, manual gate valve 4 and hydraulic gate valve 4. The shunt manifold is set in an "H" shape. The invention has the following advantages: 1. The pipeline has four inlets and eight outlets, which meets the requirements of zipper fracturing switching, and the wellhead switching is realized through the gate valve, and the switching steps are simple and easy to understand; 2. The entrances of the four main lines are opposite to each other, which buffers the large displacement The impact force of the jet on the manifold is stable throughout the high-pressure part of the construction process, while reducing the erosion force of the large-displacement fluid and prolonging the life of the manifold; 3. It is easy to connect pipelines and has a high degree of standardization.

Description

technical field [0001] The invention belongs to the technical field of drilling, and in particular relates to a high-sulfur-resistant zipper-type fracturing split manifold of a continuous drilling system. Background technique [0002] The continuous circulation drilling system is an advanced drilling technology and equipment, which can maintain the continuous circulation of drilling fluid during the single drilling period, so as to achieve stable equivalent circulating density and uninterrupted drilling cuttings discharge during the entire drilling period, avoiding pump shutdown and The bottom hole pressure fluctuation caused by the pump cycle, comprehensively improves the wellbore conditions and drilling safety, greatly reduces drilling accidents, and increases the total ROP. [0003] At present, the use of fracturing manifolds to connect fracturing manifolds and multiple fracturing wellhead devices, and to conduct fracturing operations at the same time or separately, is a ...
