Novel high-pressure manifold device

Abstract

The invention relates to a novel high-pressure manifold device. The novel high-pressure manifold device comprises a linear center manifold. A discharging port is formed in the rear end of the center manifold. A series connection-in port is formed in the front end of the center manifold, the rear end of the upper side of the center manifold is vertically connected with a first liquid inlet channel,and the front end of the lower side of the center manifold is vertically connected with a second liquid inlet channel. The center manifold is in a linear shape, the reducing area and friction lossesof the center manifold are reduced, sand setting of the high-pressure manifold is reduced, and the fracturing construction safety coefficient is improved. In addition, the included angle between the first liquid inlet channel and the center manifold and the included angle between the second liquid inlet channel and the center manifold are right angles, and accordingly erosion abrasion to the novelmanifold device from high-pressure fluid can be effectively reduced. The first liquid inlet channel and the second liquid inlet channel are arranged in a staggered manner, the vortex state of the high-pressure fluid in the center manifold can be reduced, and vibration caused by high-pressure manifold impacts due to the high-pressure fluid is reduced.

Description

technical field [0001] The invention relates to the technical field of oil testing and well completion engineering, and more specifically, relates to a novel high-pressure manifold device. Background technique [0002] The principle of hydraulic fracturing for shale gas development is to use the natural or induced fracture system of the reservoir, inject the fracturing fluid containing various additives into the formation under high pressure, expand the fracture network of the reservoir, and rely on proppant to make the fracture under pressure After the fracturing fluid returns, it will not be sealed, thereby improving the fracture network system of the reservoir and achieving the purpose of increasing production. In the exploration and development of unconventional oil and gas reservoirs such as shale gas and deep shale gas, the reservoirs are dense with ultra-low porosity and permeability, developed micro-fractures, high abundance of organic matter, large thickness, high b...
