Description

Technical Field

[0001] This invention relates to the field of oil and gas field development technology, specifically to a method and control system for adjusting the well control system of a gas well plunger gas lift. Background Technology

[0002] As gas field development enters its mid-to-late stages, the decreasing formation pressure reduces the fluid-carrying capacity of gas wells, hindering the effective removal of formation water and condensate, leading to fluid accumulation in the wellbore and severely impacting gas well production. Plunger gas lift technology utilizes a plunger as a fixed gas-liquid interface, effectively reducing gas upwelling and liquid slippage, thus improving the fluid-carrying efficiency of gas wells. Due to its advantages such as high automation, low cost, and simple installation, it is widely used in major gas fields both domestically and internationally.

[0003] Currently, conventional control methods for plunger gas lift, such as timed and pressure-controlled switches, involve a large amount of manual parameter adjustment and daily management. Furthermore, the effectiveness of parameter adjustment is highly dependent on the professional knowledge and management experience of relevant technical personnel in gas production engineering and reservoir engineering. The rationality of system adjustments cannot be guaranteed, which affects the gas field development effect. Summary of the Invention

[0045] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative effort.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0047] To address the problem that existing conventional plunger gas lift control methods rely on manual parameter adjustment, requiring specialized knowledge and management experience in gas production engineering and reservoir engineering, which cannot guarantee the rationality of the system adjustment and affects the gas field development effect, this invention provides a plunger gas lift well opening and closing system adjustment method and control system. This method utilizes production curves from multiple historical production cycles to sequentially determine the optimal well opening and closing time and cycle gas production for each historical production cycle. The optimal well opening and closing time and cycle gas production for the determined optimal well opening and closing time and cycle gas production for multiple historical production cycles are weighted and summed to obtain the optimal well opening and closing time and cycle gas production. This achieves automatic setting of the plunger gas lift well system and automatic adjustment of the on-site opening and closing, ensuring the rationality and timeliness of the system adjustment.

[0048] like Figure 1 The diagram shown is a flowchart of a gas well plunger gas lift well control system adjustment method provided by the present invention, which includes the following steps:

[0049] Step 101: Obtain production curves for N historical production cycles, for example... Figure 4 As shown, N is a positive integer greater than or equal to 1.

[0050] Step 102: Determine the optimal well opening and closing time and gas production rate for each historical production cycle in sequence based on the production curve of the historical cycle.

[0051] The well opening and closing times include the well opening time and the well closing time. The cycle gas production refers to the gas production within the corresponding historical production cycle.

[0052] It should be noted that for N historical production cycles, the optimal well opening and closing time and gas production rate for each historical production cycle need to be determined based on the production curve of that historical production cycle.

[0053] For example, based on the production curves of three historical production cycles, the optimal switching time and cycle gas production rate for each of these three historical production cycles are determined. The determination of the optimal switching time and cycle gas production rate for each historical cycle will be explained in detail later.

[0054] Step 103: Perform a weighted summation of the optimal well opening and closing times and the gas production per cycle for the N determined historical production cycles to obtain the optimal well opening and closing time and the gas production per cycle corresponding to the optimal well opening and closing system.

[0055] Assume the optimal well opening / closing time and cycle gas production for the i-th historical production cycle are respectively: T oni T offi Q i The weighted summation of the optimal well opening and closing times and the gas production per cycle for each of the N historical production cycles can be calculated using the following formula:

[0056]

[0057]

[0058]

[0059] Among them, T on T represents the well opening time corresponding to the optimal well opening / closing regime. off Let Q be the shut-in time corresponding to the optimal well-opening and shut-out regime, and let Q be the periodic gas production corresponding to the optimal well-opening and shut-out regime.

[0060] In step 102 above, when determining the optimal well opening and closing time and gas production per cycle for each historical production cycle, multiple well opening and closing regimes for each historical production cycle can be determined first. Then, for each well opening and closing regime, the gas production per unit time under that regime is calculated, and the gas production per unit time with the largest gas production is selected as the optimal regime.

[0061] The following is a detailed explanation of determining the optimal well opening and closing times and cycle gas production for each historical production cycle in step 102 above.

[0062] like Figure 2 The diagram shown is a flowchart illustrating the method of the present invention for determining the optimal well opening / closing time and cycle gas production for a historical production cycle, including the following steps:

[0063] Step 201: Determine the multiple well switching systems within the i-th historical production cycle, where i∈N.

[0064] For ease of description, the i-th historical production cycle will also be referred to as the i-th production cycle, as the two concepts are the same.

[0065] Specifically, the well-switching and casing pressure parameters for the historical production cycle can be set; based on the well-switching and casing pressure parameters, multiple well-switching and casing pressure regimes for the historical production cycle can be determined. The well-switching and casing pressure parameters include: minimum well-switching and casing pressure, maximum well-switching and casing pressure, and casing pressure increment.

[0066] The casing pressure parameters for each of the aforementioned switching wells can be set as follows: the minimum switching well casing pressure in the i-th production cycle is 0.8-1.0 times the casing pressure of the i-th production cycle, the maximum switching well casing pressure is 1.0-1.2 times the casing pressure of the i-th production cycle, and the casing pressure increment is 0.1-0.3 MPa. Of course, other settings are also possible, and this embodiment of the invention does not limit them.

[0067] In one non-limiting embodiment, the multiple well-opening and closing procedures within the historical production cycle can be determined in the following manner:

[0068] Using the minimum well opening casing pressure as the base point and the first step length as the unit, the casing pressure increment is continuously extended to the maximum well opening casing pressure to obtain K well opening casing pressures;

[0069] Using the minimum shut-in casing pressure as the base point and the second step length as the unit, the casing pressure increment is continuously extended to the maximum shut-in casing pressure to obtain L shut-in casing pressures.

[0070] The first step length and the second step length represent the increase in casing pressure during the well opening and shut-in periods, respectively.

[0071] Determine the number of well opening and closing procedures (M = K × L) within the historical production cycle.

[0072] It should be noted that K and L are positive integers greater than or equal to 1. Also, the length of the first step is not equal to the length of the second step.

[0073] Step 202: Calculate the gas production per unit time within each well-opening / closing system based on the production curve of the i-th historical production cycle.

[0074] The calculation process for the gas production per unit time under each well-opening / closing regime is as follows:

[0075] (1) For each well switching regime, the well switching casing pressure point corresponding to the well switching regime cycle is determined based on the production curve of the historical production cycle.

[0076] (2) Calculate the well opening time T based on the switch sleeve pressure point. onij and well shut-in time T offij ;

[0077] (3) Based on the well opening time T onij and well shut-in time T offij Determine the gas production per unit time within the aforementioned well-opening and closing system.

[0078] For example, for the j-th well-opening / closing regime among the M well-opening / closing regimes within the i-th production cycle, find the corresponding well-opening / closing casing pressure point on the curve of the i-th production cycle to determine the well-opening time T. onij With shut-in time T offij The gas production during the well opening time is integrated to obtain the gas production Q during the j-th well opening and closing period. ij Then, calculate the gas production Q per unit time during the j-th well switching cycle. ij平均 Q ij平均 =Q ij / (T onij +T offij ).

[0079] Step 203: Remove well switching systems in the i-th historical production cycle whose plunger gas lift operating parameters do not meet the boundary conditions.

[0080] In other words, for the M well-opening and closing regimes within the i-th historical production cycle, only the well-opening and closing regimes whose plunger gas lift operating parameters satisfy the boundary conditions are retained.

[0081] The boundary conditions include one or more of the following: load factor, plunger rise rate, range of slight increase in casing pressure at the end of well opening, and whether the plunger has reached the wellhead. The load factor can be controlled between 0.38 and 0.45, and is calculated as (casing pressure - oil pressure) / (casing pressure - back pressure). The plunger rise rate can be set to 228-305 m / min, and the range of slight increase in casing pressure at the end of well opening can be set to 5%-10%.

[0082] It should be noted that step 203 can be performed first, followed by step 202. Accordingly, when performing step 202, it is only necessary to calculate the gas production per unit time within the remaining well-opening and closing schedule.

[0083] Step 204: Select the switching time and gas production per unit time corresponding to the switching system with the maximum gas production per unit time among the remaining switching systems as the optimal switching time and gas production per cycle for the i-th historical production cycle.

[0084] For each historical production cycle, the remaining well switching regimes refer to the well switching regimes remaining after removing those whose plunger gas lift operating parameters do not meet the boundary conditions from the M well switching regimes within that historical production cycle. The number of remaining well switching regimes is less than or equal to M.

[0085] The gas well plunger gas lift well control adjustment method provided by this invention utilizes production curves from multiple historical production cycles to sequentially determine the optimal well control time and cycle gas production for each historical production cycle. The optimal well control time and cycle gas production for each of the determined historical production cycles are then weighted and summed to obtain the optimal well control time and cycle gas production. This achieves automatic setting of the plunger gas lift well control system and automatic adjustment of on-site switching, ensuring the rationality and timeliness of the system adjustment. Using this invention, the automatic adjustment and execution of the gas well plunger gas lift well control system not only reduces labor costs but also effectively improves gas field development efficiency.
