Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] like figure 1 Shown, a kind of automatic control method of removing effusion of gas well, described automatic control method comprises the following steps:

[0050] Step 200, collecting parameters related to fluid accumulation in the gas well;

[0051] Step 300, analyze and calculate the collected parameters related to the fluid accumulation of the gas well through a formula to determine whether the gas well has fluid accumulation, if there is fluid accumulation, perform step 400, and if there is no fluid accumulation, perform step 200;

[0052] Step 400, execute the instruction of adding medicine according to the analysis and calculation results.

[0053] Among them, the method of judging whether a gas well has fluid accumula...

Abstract

The invention discloses an automatic control method for removal of gas well deposition liquid. The automatic control method comprises the following steps: step 200, collecting relative parameters of the gas well deposition liquid; step 300, performing analytical calculation on the collected relative parameters of the gas well deposition liquid through formulas, judging whether the deposition liquid is generated in the gas well, performing step 400 if the deposition liquid is generated in the gas well and performing step 200 if the deposition liquid is not generated in the gas well; and step 400, performing a drug dosing instruction according to analytical calculation results. Through the automatic control method for removal of gas well deposition liquid, the deposition liquid in the gas well can be judged accurately through combination of deposition liquid judging software and the collected relative parameters of the gas well deposition liquid; and meanwhile, the deposition liquid judging software is capable of quickly processing in batches, so that the normal production of the gas well and the extraction degree of the natural gas are greatly accelerated.

Description

technical field [0001] The invention relates to the field of natural gas exploitation, in particular to an automatic control method for guiding a gas well to remove liquid accumulation by judging whether the gas well has liquid accumulation. Background technique [0002] In the process of natural gas exploitation in gas fields, with the deepening of development, formation energy gradually decreases, and formation water also appears, and the liquid carrying capacity of natural gas weakens, resulting in increasing wellbore fluid accumulation. If wellbore fluid accumulation cannot be discharged in time, It will cause the wellhead pressure to decrease, thereby increasing the back pressure of the liquid on the gas layer, resulting in a sharp drop in natural gas production, and even dead wells. For liquid-loaded gas wells, the most widely used method is the injection of foam drainage agent, foam drainage and drainage gas recovery measures. Generally, foam drainage truck is used fo...
