Description
Technical Field
The invention belongs to the technical field of natural gas yield increase, and particularly relates to the technical field of pigging and spontaneous bubble foam wastewater products in a natural gas gathering and transportation pipeline.
Background
In the middle and later stages of gas field development, stratum pressure is reduced, edge and bottom water is pushed, fracturing, acidizing and other operations are carried out, and all water producing gas wells finally generate bottom hole liquid accumulation when gas reservoirs are exhausted no matter in a high-permeability reservoir or a low-permeability reservoir. A plurality of methods are adopted to eliminate accumulated liquid at the bottom of a well, wherein a foam drainage method is widely applied due to low cost, easy construction and no influence on the production of a gas well, so that a gas-water mixture produced by the gas well needs to be conveyed to a gas collecting station by a branch pipe network for separation and purification treatment.
In order to reduce the development cost of natural gas and simplify the ground engineering facilities and management difficulty, most gas field well heads in China are not provided with a gas-liquid separator, but most gas field ground gathering and transporting pipelines are buried and laid horizontally or have small fluctuation, gas-water mixtures extracted by a foam gas exhausting well are layered in the ground gathering and transporting pipelines under the action of gravity and low disturbance, foams are broken, the action of gas-carried water is obviously reduced, accumulated liquid in the gathering and transporting pipelines is gradually increased, and the difficulty of ground gathering and transporting of foam drainage gas recovery wells is greatly increased; particularly in winter, the pipeline is easy to be frozen and blocked due to more liquid content in the gathering and transportation pipeline, and the normal production of natural gas is seriously influenced; in addition, the solid impurities in the natural gas gathering and transportation pipeline can also influence the normal transportation of the natural gas.
In order to solve the problems, in the prior art, a spherical pig is adopted to solve, for example, a mechanical spherical pig for a long-distance gas transmission pipeline of cn201920685173.x, and cleaning and draining water for the pipeline by using a spherical pig made of corrosion-resistant chloroprene rubber are tried in many places, but the spherical pig is easy to be blocked to cause accidents, and the spherical pig is troublesome to throw and recover. In order to solve the problem of blocking of a spherical pig, patent CN201110046730.1 discloses a repeated foaming device for a gathering and transporting pipeline of a foam drainage gas recovery well, which provides a device for re-foaming accumulated liquid in the gathering and transporting pipeline so as to smoothly convey the accumulated liquid in the pipeline to a gas collecting station for separation treatment. However, the foaming agent is used in the device, and the foaming agent has the problem that floating is difficult to control during adding and using, so that a large amount of active agent in the upper accumulated liquid is quickly discharged when the action is not fully exerted, and therefore, the liquid filling mode has the characteristics of short action time and low efficiency, and the resource utilization maximization cannot be realized.
The conventional foam row products also comprise solid foam row rods and foam row balls. When the foam discharging rod is applied to a conveying pipeline with a complex structure, particularly in a large-inclination and small-angle turning pipeline, the condition that the strip-shaped foam discharging rod is clamped halfway and cannot enter a liquid accumulation section can occur, the foam discharging effect is influenced, the foam discharging ball is quickly dissolved, and the foaming time is difficult to control.

The following examples further illustrate the present invention but are not to be construed as limiting the invention. Modifications or substitutions to methods, procedures, or conditions of the invention may be made without departing from the spirit and scope of the invention.
The first embodiment is as follows: preparation method of self-foaming type pipe cleaning drainage ball for gathering and transportation pipeline
The invention provides a method for preparing a self-foaming clear pipe drainage ball for a gathering and transportation pipeline, which comprises the following steps:
(1) preparing a main agent: and fully mixing the foaming agent and the foam stabilizer, adding the self-foaming active mixture, the breaking agent and the lubricating mold release agent, fully drying and uniformly mixing.

In the experiment, the invention also adopts the steps of removing the pressure in the die when the oil pressure reaches 10Mpa, taking out the foam volleyball, spraying polyethylene glycol on the surface of the foam volleyball after melting at the high temperature of 100 ℃ and cooling to the room temperature.
Example two: self-foaming type clear pipe drainage ball for gathering pipeline
The self-foaming type clear pipe drainage ball for the gathering pipeline is internally provided with a mixture of a surfactant and an auxiliary agent, and the surface of the self-foaming type clear pipe drainage ball is provided with a time delay coating.
The mixture of the surfactant and the auxiliary agent in the self-foaming type pipe cleaning and draining ball contains a foaming agent, a foam stabilizer, a self-foaming active substance, a breaking agent and a lubricating and releasing agent, and the time delay coating adopts polyethylene glycol.
The best formula of the embodiment is as follows: the foaming agent adopts a mixture of a nonionic surfactant and an anionic surfactant in a ratio of 1:1, the foam stabilizer adopts the nonionic surfactant, the self-foaming active substance adopts a mixture of solid acid and sodium bicarbonate in a ratio of 3:2, the breaking agent adopts sodium chloride, the lubricating and releasing agent adopts sodium benzoate, and the time-delay coating adopts polyethylene glycol.
The formulations used for the specific experiments are shown in table 1 below:
table 1: formula of self-foaming pipe cleaning drainage ball for gathering and transportation pipeline
The foaming agent of the invention mainly reduces the surface tension of water, so that the accumulated liquid in the pipeline can be foamed.
In the invention, a common foaming agent of common betaine is adopted, but experiments show that although the foaming amount of the betaine is slightly larger than that of fatty alcohol polyoxyethylene ether (AEO), the half-life period is shorter (the half-life period of the foamed betaine in field water is 5-8min, and the half-life period of the AEO is 8-12min, but the foam stability is insufficient), and the requirement that the pipeline is finally taken out of a pipeline after accumulated liquid in the pipeline is changed into foam and is transported with an air flow for a long distance cannot be met. The sodium dodecyl sulfate has the largest foaming amount in clear water, good foaming performance and the highest foam height which is about 1.5 times of that of betaine and AEO, but has the defect that the sodium dodecyl sulfate cannot be used independently and must be compounded with other foaming agents, and the half life period of the sodium dodecyl sulfate is 2-3 min. Through multiple experiments, the final determination that the fatty alcohol-polyoxyethylene ether and the sodium dodecyl sulfate can meet the foaming requirement and the half-life period requirement when being compounded is carried out, particularly when the fatty alcohol-polyoxyethylene ether and the sodium dodecyl sulfate are 1:1 the effect is best when the foaming agent is compounded, and after the foaming agent is added into the foam stabilizer after final compounding, the half-life period of more than one hour can be achieved in water in an oil-containing field.
The foam stabilizer is compatible with the foaming agent to improve the performance, and has the capability of enhancing the stability, permeability, cleaning property and hard water resistance of the foam.
The self-foaming active matter has the main function of enabling the spherical pig to rapidly generate chemical reaction after encountering effusion, generating a large amount of carbon dioxide gas and converting the effusion in the pipe into foam.
The main function of the breaking agent is to accelerate the dissolution of the foam volleyball at the effusion.
The lubricating release agent mainly has the effects of reducing the friction force between the foam volleyball and the mould, enabling the product to be easily released and reducing the forming difficulty.
The time-delay coating mainly has the functions of increasing the structural strength of the spherical pig, increasing the moving distance of the spherical pig in the pipeline and preventing premature reaction before the spherical pig reaches accumulated liquid, and the thickness of the time-delay coating is 0.5-1.5mm, wherein the amount of the accumulated liquid can be increased or reduced by the polyethylene glycol spraying thickness according to the length of a pipeline on site.
Example three: self-foaming pigging drainage ball performance experiment for gathering pipeline
1. Foam quality test
In the experiment, foaming components in the foam volleyball with the same quality and the commercial product foam volleyball powder are stirred and measured by a GJ-2000 high-speed stirrer in an on-site water sample (2g, 9000 revolutions and 1min), and the data are shown in Table 2.
TABLE 2 foaming comparison experiment
| Pickled pork chop product | Height of bubbling | Half-life of foam |

According to experimental results, compared with a plurality of commercial foam discharging products, the composite surfactant in the foam discharging spherical pig can generate dense foam in an on-site pipeline water sample, has long foam half-life period, and is suitable for long-distance movement of liquid carried in a pipeline.
2. Delayed coating experiment
The product of the invention is externally wrapped with a layer of soluble time-delay coating, the coating increases the structural strength of the product, can prevent the water vapor in the pipeline from reacting with the internal structure prematurely, and can control the reaction time of the foam volleyball by controlling the thickness of the coating, wherein the thickness of the coating and the reaction time of the foam volleyball are shown in the attached figure 1 of the specification.
In the experiment, the vertical free-falling fragmentation height of no sprayed polyethylene glycol is less than 25cm, the strength is increased along with the spraying thickness, the spraying thickness is 1cm, and the vertical fragmentation height can be increased to 40 cm.
3. In-situ pipeline ball-throwing experiment
The ball is thrown into the gathering pipeline through the remote automatic ball throwing equipment on site once every two hours, and 1 ball is thrown each time. According to the field experiment feedback result of the second factory of the Changqing gas production, the natural gas entering pressure is increased for a short time and then gradually decreased within one week after continuous ball throwing, which shows that accumulated liquid in the pipeline moves along with the throwing of the spherical pig and is finally taken out of the pipeline.
