Abstract

The utility model discloses a fracturing manifold. The fracturing manifold comprises a fracturing main tube (1) connected with a fracturing wellhead. The fracturing manifold is characterized in that a plurality of tilting tee joints (2) which are sequentially connected are arranged at the inlet end of the fracturing main tube (1), branch pipe inlets in the tilting tee joints (2) are all connected with one-way valves (4) through plug valves (3), and pressure inlets of the one-way valves (4) are communicated with an output port of a high-pressure pump. According to the fracturing manifold, the tilting tee joints which are connected with one another are arranged to be connected with the fracturing main tube, components are arranged on branch pipes of the tilting tee joints to be communicated with the output port of the high-pressure pump, so that the fracturing manifold is formed, hence, under the condition that the work steps and the labor intensity are not increased, a pressure inlet channel of the fracturing manifold is increased, the discharging capacity in the fracturing process is increased, and the operation efficacy is improved. The fracturing manifold can meet the requirement for large-discharging-capacity high-pressure fracturing operation, and the fracturing efficiency is improved.

Description

A kind of fracture manifold

Technical field

The utility model relates to a kind of fracturing fluid to injecting high pressure, large discharge capacity in oil well or gas well, to increase ground layer gap, to improve the penetrating power of oil reservoir and gas-bearing formation, thereby reaches volume increase object and the fracture manifold that uses.

Background technology

At present, fracture manifold can only complete single oil pipe fracturing work or the casing fracturing carrying out of small displacement.Can not meet oil pipe in many high-pressure pumps while infusion pressure breaks of 70Mpa, also will and add sand construction from oil jacket annular space infusion liquid.

Summary of the invention

The purpose of this utility model is the problem existing for existing fracture manifold, provides a kind of entrance pressure passage, increase pressure break discharge capacity of increasing to improve the fracture manifold of operating efficiency.

The purpose of this utility model solves by the following technical programs:

A kind of fracture manifold, comprise the pressure break supervisor who is connected with fracture well head, the entrance point that it is characterized in that described pressure break supervisor arranges a plurality of connected skew Ts successively, and the arm import on skew T is all connected with one way valve by plug valve, and the entrance pressure mouth of one way valve is connected with the delivery outlet of high-pressure pump.

Supervisor's port of export of the skew T of tail end position is connected with pressure break supervisor's entrance point, supervisor's entrance point of the skew T of tail end position is connected with supervisor's port of export of the skew T at its forward position place successively, and supervisor's entrance point of the skew T of head end position is arranged on base.

The arm of described skew T tilts to supervisor's entrance point of skew T.

Described skew T adopts 45 ° of skew Ts.

The utility model has the following advantages compared to existing technology:

The utility model is connected and parts is set on the arm of skew T and be connected to form fracture manifold with the delivery outlet of high-pressure pump by a plurality of interconnective skew Ts and pressure break supervisor is set, thereby do not increasing under the situation of job step and labour intensity, increasing the entrance pressure passage of fracture manifold, the discharge capacity while having increased pressure break and improved operation effect; This fracture manifold can meet the demand of large discharge capacity high pressure fracturing work, has improved pressure break efficiency.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model.

Wherein: 1-pressure break supervisor; 2-skew T; 3-plug valve; 4-one way valve; 5-base.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

As shown in Figure 1: a kind of fracture manifold, comprise the pressure break supervisor 1 who is connected with fracture well head, at pressure break supervisor 1 entrance point, a plurality of connected skew Ts 2 are successively set, supervisor's port of export of the skew T 2 of tail end position is connected with pressure break supervisor 2 entrance point, supervisor's entrance point of the skew T 2 of tail end position is connected with supervisor's port of export of the skew T 2 at its forward position place successively, and supervisor's entrance point of the skew T 2 of head end position is arranged on base 5; Arm import on each skew T 2 is all connected with one way valve 4 by plug valve 3, and the entrance pressure mouth of one way valve 4 is connected with the delivery outlet of high-pressure pump.In above-mentioned fracture manifold, the arm of skew T 2 tilts to supervisor's entrance point of skew T 2, and specifically, skew T 2 adopts 45 ° of skew Ts.

When the utility model is used, pressure break supervisor 1 is fixed in pressure break import, many fracturing unit trucks connect fracture manifold by the entrance pressure mouth of one way valve 4 simultaneously, to in well with high pressure, at a high speed, large discharge capacity injects fracturing fluid, rely on the effect of liquid transfering pressure, when the speed of high-pressure pump group injection is greater than the suction strainer speed on stratum, just near stratum, form very high pressure, this pressure surpasses formation rock anti-ly connects, during compressive strength, original crack, stratum will expand, and forms larger crack or produces new crack; Thereby reach the object of pressure break.

The utility model is connected and parts is set on the arm of skew T 2 and be connected to form fracture manifold with the delivery outlet of high-pressure pump by a plurality of interconnective skew Ts 2 and pressure break supervisor 1 is set, thereby do not increasing under the situation of job step and labour intensity, increasing the entrance pressure passage of fracture manifold, the discharge capacity while having increased pressure break and improved operation effect; This fracture manifold can meet the demand of large discharge capacity high pressure fracturing work, has improved pressure break efficiency.

Above embodiment is only explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
