Abstract

The utility model relates to a multiple-hit type well head connector, which comprises a body case, a gunlock part equipped in the body case. The gunlock part is connected with the gun body part through an attaching nut. The particular structure is that a big hollow cavity is arranged in the gunlock part, and a spring and many small hollow cavities are arranged in the big hollow cavity. The small hollow cavity is equipped with a needle inside of which upper end part is corresponded with the hammer of the upper wheel. The lower part positioned through a bracket cap nut is corresponded with the sound bomb in the gun body. A wheel seat is equipped below the upper wheel, and an operating grip and a safety anchor are arranged on the upper end of the body case. The operating grip is connected with a fork spreader that is connected with the upper wheel. The gun body is equipped with a cartridge chamber, in which a sound bomb is provided; one side of the gun body is equipped with an atmospheric valve, and the other side is equipped with a reception chamber that is equipped with a microphone inside. 2/3 bombs are sent together if the product is toggled once. The utility model is matched with the well depth measuring apparatus to measure the liquid level of the oil well, and belongs to the echo method depth test equipment.

Description

Multi-hit wellhead connector

Technical field: the utility model relates to a kind of multi-hit wellhead connector, and promptly stirring once to have 2/3 bullet to volley, and measures oil well liquid level with the supporting use of well depth survey instrument, belongs to echo method depth test equipment.

Background technology: existing wellhead connector is all clicked, and promptly once launches a sound bullet.Adopt the connector of this spline structure to survey not come out for the oil well liquid level of the nearly 10%-20% of old filed, this can bring problems to production.

Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of by increasing that the sound source energy is equipped with high sensitivity microphony sensor again and the multi-hit wellhead connector that can solve low pressure deep-well liquid level gauging basically to people.For achieving the above object, the utility model adopts following technical proposals: multi-hit wellhead connector, comprise casing (1), casing is provided with the gunlock part in (1), and gunlock partly is connected with the rifle body portion by attaching nut (9), and its concrete structure is: gunlock partly is shaped on a big cavity, in the big cavity spring (16) is housed, also be shaped on a plurality of areolas, be provided with eedle (3) in the areola, the hammer (2) of eedle (3) upper end and last wheel (11) is corresponding; The lower end is by support nut (17) location and corresponding with rifle body (4) interior sound bullet (8), last wheel (11) has wheel seat (10), operating grip (13) and insurance nail (14) are equipped with in casing (1) upper end, its operating grip (13) is connected with shift fork (12), and shift fork (12) is connected with last wheel (11).Rifle body (4) is provided with cartridge chamber (7), and bullet (8) is housed in the cartridge chamber (7), and a side of rifle body (4) is equipped with atmospheric valve (6); Opposite side is installed receiving chamber (5), establishes microphone (15) in the receiving chamber (5).

Characteristics of the present utility model are: owing to adopted the design of many bullets and multi-hit iron, realized multi-hit, thereby increase the sound source energy, echo signal is increased, be equipped with high sensitivity microphony sensor again, the liquid level that can solve old filed low pressure deep-well is effectively surveyed the technical barrier not come out.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the schematic diagram after the utility model percussion.

The specific embodiment:

With reference to Fig. 1,2, multi-hit wellhead connector, comprise casing 1, be provided with the gunlock part in the casing 1, gunlock partly is connected with the rifle body portion by attaching nut 9, and its concrete structure is: gunlock partly is shaped on a big cavity, in the big cavity spring 16 is housed, also be shaped on a plurality of areolas, be provided with eedle 3 in the areola, the hammer 2 of eedle 3 upper ends and last wheel 11 is corresponding; The lower end is by support nut 17 location and corresponding with rifle body 4 interior bullets 8, and last wheel 11 has wheel seat 10, and operating grip 13 and insurance nail 14 are equipped with in casing 1 upper end, and its operating grip 13 is connected with shift fork 12, and shift fork 12 is connected with last wheel 11.Rifle body 4 is provided with cartridge chamber 7, and bullet 8 is housed in the cartridge chamber 7, and a side of rifle body 4 is equipped with atmospheric valve 6; Opposite side is installed receiving chamber 5, establishes microphone 15 in the receiving chamber 5.

With after the oil pipe of oil well is connected, concrete operations are as described below with the utility model rifle body lower end:

(1) unclamps check screw;

(2) pull operating grip, at this moment, last wheel lifts compression bullet spring, by the time under the spring force effect, last wheel descends and the drive hammer is pounded suddenly on eedle during the next position, eedle moment moves down, needle point is the percussive sound bullet fire in a stove before fuel is added just in time, causes the bullet blast, sounds.This sound reaches the oil well liquid level echogenicity, echo is received by the microphony sensor, and pass to echometer and carry out the data processing, the reception of the echo sound wave that produces when the sound wave in when emission and sound are arrived oil well liquid level, and the time interval between them, can calculate the degree of depth of liquid level, establish a plurality of cartridge chambers in the rifle body, bullet is housed in each cartridge chamber, and sound plays alternate percussion during emission.Its model has two bullets to volley and three bullets volley, and corresponding emitting times has 3 times and 2 inferior various combinations.
