Cluster gas well dosing device and intelligent effusion-diagnosis and effusion quantity-calculation method

Abstract

The invention provides a cluster gas well dosing device and an intelligent effusion-diagnosis and effusion quantity-calculation method, and belongs to the technical field of control over dosing and filling capacity. The cluster gas well dosing device is mainly composed of a solar cell, a wind generator, a charge controller, a storage battery pack, a dose storage box, a level meter, a direct current gear motor, a high pressure plunger pump, an intelligent dosing controller, a multi-well gate valve terminal and a wireless communication unit; the dose storage box and the high pressure plunger pump, and the high pressure plunger pump and the wireless communication unit are connected by pipelines; outlets in the back of the multi-well gate valve terminal are connected with check valves; the rest devices are connected by a control circuit, transmission of power and instructions is maintained, the outlet pipeline of the high pressure plunger pump is in parallel connection with the multi-well gate valve terminal, eight solenoid valves are arranged on the multi-well gate valve terminal, and the outlet of each solenoid valve is connected with a dosing opening of each gas well through a pipeline; check valves are connected to the pipelines from the outlets of the solenoid valves to the dosing openings of the gas wells respectively. By adopting the cluster gas well dosing device and the intelligent effusion-diagnosis and effusion quantity-calculation method, the intelligent control and remote operation of dosing on the well site, and automatic collection of dosing data are realized.

Description

technical field [0001] The invention relates to a cluster type gas well dosing device and a method for intelligently diagnosing effusion and calculating the effusion volume, and belongs to the technical field of dosing and injection volume control. Background technique [0002] In the process of natural gas exploitation, with the development of the gas field, the energy of the formation gradually decreases, the liquid-carrying capacity of the gas weakens, and the fluid in the wellbore gradually increases. If the fluid in the wellbore cannot be discharged in time, the back pressure of the liquid on the gas layer will increase, resulting in Natural gas production has dropped sharply, and even flooding has occurred. The traditional method of discharging effusion is mainly to inject foaming agent at the wellhead by a mobile vehicle or put in foaming rods and other measures. Problems such as low efficiency and untimely filling have gradually emerged, which have seriously affected...
