Abstract
The invention discloses a method for defoaming a pipeline from the mouth of a gas well to a separator by using a solid defoamer device. The method comprises the following steps of: mounting the solid defoamer device on the gas transmission pipeline between the mouth of the natural gas well and the separator; specially making a defoamer be in a solid state and putting the solid defoamer into the solid defoamer device; enabling the solid defoamer to be in direct contact with transmission fluid; and dissolving the solid defoamer by the transmission fluid. The method has the beneficial effects that: the method is energy-saving and consumption-reducing and has no need of using a plunger pump and electric energy; the solid defoamer device has an automatic adjustment function, when liquid is produced, the solid defoamer is dissolved, when the liquid producing capacity is larger, more solid defoamer is dissolved, and thus, the waste of pharmaceutical products is avoided; the solid defoamer is placed in the solid defoamer device at a time and can be used for a number of days, and the daily putting is not needed, so that the cost for production and maintenance of the gas well is greatly saved, the technical difficulty and the labor intensity in operation are reduced, and the labor power is saved; and the fluid is in sufficient contact with the solid defoamer, the defoaming is complete, and the accident that foams cross a tower can be effectively prevented, so that the method is safe and reliable.
Description
Technical field
The present invention relates to natural gas well well head to separator gas transmission line inner foam and eliminate the technical field of technique, particularly a kind of solid defoamer device is eliminated gas well mouth to the method for foam in separator pipeline.
Background technology
The natural gas well, because annotating after foaming water discharge agent, need carry out froth breaking, thereby better realize gas-liquid separation before foam enters separator.At present, the method that foam killer filling adopts in foam drainage gas recovery technique is: with plunger displacement pump, liquid defoamer is injected to pipeline, to eliminate the foam in pipeline.The device structure complexity that this technique is required, equipment rapid wear, not only affects defoaming effect but also increase maintenance cost; Need every day simultaneously and dilute medicament, labour intensity is large, the injection state due to plunger displacement pump of the more important thing is is a line states, foam and defoamer contact-making surface are less, and the rate of flow of fluid in pipeline is very fast, thereby cause a lot of foams to contact with defoamer, time have froth breaking not thorough, the accident that foam turns over tower occurs.This problem affects effectively carrying out of foam drainage gas recovery technique always.
And because the natural gas well all exists fluid discontinuity, sometimes the foam of output is compared with horn of plenty, sometimes non-foam output again, and because air delivering pipeline is the system of a sealing, cannot be from surface observation to its inner case, in order not affect de-foaming process, traditional liquid defoamer all adopts continuously and adds, and sometimes needs within 24 hours, add continuously.Therefore, at gas well, not during fluid, also at foam killer filling, cause the waste of defoamer; In addition, when, foam large in natural gas well production fluid amount enriches, owing to there is no to increase in time the adding amount of defoamer, cause froth breaking not in time, also can cause foam to turn over the generation of tower accident.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of equipment needed thereby is simple in structure, easy and simple to handle, production efficiency is high, can automatically regulate a kind of solid defoamer device of delivering medicament amount to eliminate gas well mouth to the method for foam in separator pipeline according to operating mode.
Object of the present invention is achieved through the following technical solutions:
Solid defoamer device is eliminated gas well mouth to the method for foam in separator pipeline, it comprises a solid defoamer device, described solid defoamer device comprises main body and the inlet valve being connected with main body by pipe fitting, filler valve, outlet valve, fixed network is installed in main body, described solid defoamer device is arranged on to natural gas well well head to the gas transmission line between separator, the special one-tenth solid of defoamer shape is placed in the fixed network of solid defoamer device, make solid defoamer directly with carry fluid contact, and by carrying fluid that solid defoamer is dissolved.
Described natural gas well well head to the gas transmission line between separator comprises bypass line.
Solid defoamer in described solid defoamer device runs out of, while needing filling solid defoamer, first open filler valve, fixed network in device is taken out, again to the in-built solid defoamer that fills up of fixed network, fixed network is packed in solid defoamer device again, then close filler valve, complete filler operation.
The present invention has the following advantages:
1, energy-saving and cost-reducing.
The present invention is demand pole plug pump and electric energy not, solid defoamer directly contacts with gas-liquid (foam) on gas transmission line, only when gas-liquid (foam) output, solid defoamer is just dissolved, eliminates foam, if when production fluid amount is larger, just much dissolved, the function with automatic adjusting, has stopped medicament waste, has greatly saved the production maintenance cost of gas well.
2, simple to operate, save manpower.
Device structure required for the present invention is simple, and solid defoamer single step of releasing is placed in solid defoamer device, can use somely day, does not need throw in every day, has reduced operation labour intensity, saves manpower, and medicament changes the outfit conveniently, and technical difficulty is little.
3, safety.
Use the method, because solid defoamer has certain length in pipeline, increased the contact-making surface of solid defoamer and gas-liquid (foam), gas-liquid (foam) contacts with solid defoamer fully, defoaming effect is more thorough, can effectively prevent from turning over because of foam the accident that downstream is polluted that tower causes.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but protection scope of the present invention is not limited to the following stated:
Solid defoamer device is eliminated gas well mouth to the method for foam in separator pipeline, as shown in Figure 1, at natural gas well well head to separator gas transmission line, apart from the position of 30 meters of left and right of separator, in the mode of bypass, one solid defoamer device is installed, solid defoamer device comprises main body 8, inlet valve 1, filler valve 2, outlet valve 3, valve A4 is installed on main line, on one end pipeline in parallel with solid defoamer device, valve B5 is installed, solid defoamer is placed in the main body 8 of solid defoamer device by filler valve 2.
As shown in Figure 2, in the main body 8 of solid defoamer device, fixed network 6 is installed, the solid defoamer of special one-tenth solid shape is filled in fixed network 6, the two ends of main body 8 are also provided with two impellers 7, for this fixed network 6 of supporting and location.
After the mode connecting gas transmission pipe line of solid defoamer device with bypass, open successively outlet valve 3, inlet valve 1, valve-off B5, finally open valve A4, fluid in pipeline can enter main body 8 from inlet valve 1, fluid directly contacts with the solid defoamer in fixed network 6, and it is dissolved, thereby realizes de-foaming process.
