Abstract
The utility model relates to a foam generator, which belongs to the technical field of a foam generator which generates foamed acid in the measure of an oilfield acidizing technique. The utility model comprises an upper connecting joint, a gas-distribution pipe, a fluid inlet pipe, a main body pipe and an outlet connecting joint. A spiral agitating short section is mounted in the main body pipe of the lower end of the gas-distribution pipe, a communicating pore on the wall of the main body pipe is vertically welded with the fluid inlet pipe, a fluid inlet nozzle baffle plate is positioned on the intersection between the fluid inlet pipe and the main body pipe, a groove in the fluid inlet pipe is positioned with the outer pipe wall of the main body pipe, and a secondary nozzle baffle plate with a nozzle hole is mounted on the connecting position between the main body pipe and the outlet connecting joint. The stimulation technology such as foamed acid and the like utilizes the foam generator to produced even foam fluid with low density, which can meet the need of oilfield field production, the quality of foam is high, and a better economic benefit is generated.
Description
Technical field:
The utility model relates to a kind of foam maker, produce the isolated plant of foam in measures such as under balance pressure drilling, completion, well workover and the well production increment construction of genus industrial gas oil and coal bed gas, be specially adapted to produce in the acidification technique measure foam maker of foamed acid.
Background technology:
In the foam job execution of oil field, the foam-making apparatus of employing is a lot of at present, and its performance satisfies different separately instructions for uses.And for the foamed acid metallization processes, it can not satisfy foam acidifying requirement fully.The CN01232201.6 (concentric tube type foam maker) that announces of patent for example, for using it to produce foamed acid, owing to its structure design reason, feed pathway, venthole can not mix uniformly with base fluid, can not produce size evenly, the foamed acid of stable performance, can only carry out the one-level foam and generate.
Summary of the invention:
The purpose of this utility model is to solve the problem that above-mentioned prior art exists, and provides in a kind of foam acidifying or other foam job execution that is applicable to industrial gas oil, can produce the foam maker of big or small even, stable performance, assurance foam quality.
The utility model is made up of upper binding head, gas-distribution pipe, feed tube, main body pipe, outlet connector, upper binding head is threaded with gas-distribution pipe, interior shoulder by upper binding head is set upright, the gas-distribution pipe end is a blind hole, gas-distribution pipe be placed on the main body pipe in intracardiac, in the main body pipe of gas-distribution pipe lower end, the helical stir pipe nipple is installed; Intercommunicating pore place vertical welding on the tube wall of main body pipe is connected to feed tube, and the feed liquor nozzle blade is placed on feed tube and main body pipe intersection, by groove in the feed tube and main body pipe outer tube wall location; In the main body pipe and the junction of outlet connector the secondary nozzle dividing plate that has nozzle bore is installed.
Gas, liquid two-phase are after gas-distribution pipe and feed tube enter generator respectively, the gas-liquid one-level is mixed, enter into again in the helical stir pipe nipple, enter the secondary nozzle dividing plate that has nozzle bore after fully stirring again by rotating freely of helical stir pipe nipple and spray and mix once more, form uniform foam after the outlet connector is discharged.
This device can bear bigger pressure, satisfies the requirement that the on-the-spot deep well high pressure in oil field injects operation, utilizes this generator to carry out yield-increasing techniques such as foam acidifying, can produce low-density uniform aerated fluid, it is required to satisfy the oil field produced on-site, and the foam quality height produces favorable economic benefit.
