Description

Technical Field

[0001] This utility model relates to the field of oil and gas field development technology, and in particular to a mobile automatic chemical dosing device for pumping wellheads. Background Technology

[0002] Currently, oilfields mainly use casing chemical dosing at the wellhead, regularly and continuously adding chemical agents into the oil well casing. This method has achieved good overall effects in wax removal, scale prevention, and corrosion inhibition, and is widely used in production. However, casing chemical dosing has many shortcomings, such as large workload, inaccurate concentration measurement, easy spillage of chemicals, risk of poisoning due to lack of airtightness, and lack of mobility. In view of the current situation of large jurisdiction areas and numerous well sites, this paper proposes to develop a mobile, airtight, and intelligent chemical dosing technology to promote the overall advancement of wax removal, scale prevention, and corrosion inhibition technologies towards refinement and quantification.

[0003] In the use of automated dosing devices, traditional dosing methods mainly rely on manual operation, which involves estimating the amount of chemical to be added and conducting regular inspections to complete the operation. These devices typically consist of a basic pump body, a storage tank, and manual valves, and lack automated control and data monitoring functions. With the increasing requirements for digital management in oilfields, existing technologies have gradually revealed defects such as low dosing accuracy, frequent manual intervention, and prominent safety hazards. In particular, in remote well sites or large-scale well group management, traditional devices can hardly meet the needs of efficient and safe production.

[0004] Therefore, to address the aforementioned inconveniences in improving dosing efficiency, avoiding the problems of traditional estimation-based dosing methods, reducing chemical spillage and inaccurate metering, a mobile automatic dosing device for pumping wellheads can be designed. During operation, this device utilizes digital remote transmission of production data management. Chemicals are drawn into a storage tank via a self-priming pump, pressurized by a plunger pump, metered, and finally injected into the wellhead casing. The entire process is monitored and data is transmitted. It features precise dosing, remote control, mobile sealing, and fully automated dosing, avoiding the influence of human factors on dosing frequency and dosage. This device allows for rapid and accurate dosing, improving efficiency, avoiding the problems of estimation-based dosing, reducing chemical spillage and inaccurate metering, and eliminating risks of chemical corrosion and poisoning for operators. This device fully meets the needs of production sites. Utility Model Content

[0200] 2. RTU11 automatically selects the type of reagent based on oil well operating data, such as wax thickness and water cut. For example, when the water cut is >70%, the wax solvent is used first.

[0201] II. Automatic Liquid Replenishment and Filtration:

[0202] 1. The replenishment pump (14) delivers the selected medicine to the medicine storage tank 7 through the one-way valve 20. The Y-type filter 3 intercepts impurities and prevents the plunger pump 2 from becoming clogged.

[0203] 2. The digital flow meter 5 monitors the replenishment volume in real time. When the liquid level in the storage tank 7 reaches 90%, the RTU11 closes the solenoid valve to stop replenishment.

[0204] III. Dosing and Data Recording:

[0205] 1. The plunger pump 2 draws the reagent from the storage tank 7, pressurizes it, and injects it into the wellhead casing through the automatic reel 9.

[0206] 2. The data transmission platform 12 records parameters such as drug dosing type, time, and flow rate, generating a traceable electronic ledger.

[0207] Beneficial effects:

[0208] 1. Wax removal efficiency increased by 40%

[0209] Traditional single-agent systems have a wax removal efficiency of only 65%, while switching to dual-agent systems achieves 91%, extending the wax deposition cycle.

[0210] Case Study: A high water-cut oil well requires monthly wax removal using the traditional method. After optimization, the wax removal cycle is extended to [number missing].

[0211] 2. Drug residue reduced by 87%

[0212] The solenoid valve assembly enables zero-residue switching of the agent, with traditional systems having agent residues of up to 15%, while the optimized system has only 2%.

[0213] Case Study: In a certain chemical replacement operation, the traditional method wastes chemical agents, while the optimized method reduces the waste.

[0214] 3. Human intervention reduced by 90%

[0215] The RTU11 automatically determines the type of reagent, eliminating the need for manual on-site operation and reducing the frequency of single-well inspections from 4 times / day to 0.4 times / day.

[0242] The specific implementation process of this embodiment is as follows:

[0243] I. Pressure Monitoring and Pressure Relief Logic:

[0244] 1. Pressure transmitter 6 monitors system pressure in real time. When the pressure exceeds the set value, RTU11 triggers the relief valve 22 to open.

[0245] 2. Overflow pipe 21 diverts excess reagent to a dedicated recycling bin to prevent reagent leakage and environmental pollution.

[0246] II. Audible and visual alarms and remote notifications:

[0247] 1. Pressure gauge 19 displays an abnormal pressure value, and at the same time, the red warning light flashes and the buzzer sounds to alert on-site personnel.

[0248] 2. RTU11 sends alarm SMS messages and pressure curves to management personnel through data transmission platform 12.

[0249] III. Fault Diagnosis and Recovery:

[0250] 1. RTU11 records overflow event time, pressure peak and other data to help analyze the cause of the fault, such as blockage of plunger pump 2 or valve failure.

[0251] 2. After troubleshooting, use the touch screen to control the reset overflow valve 22 inside the electrical box 10 to restore the dosing process.

[0252] Beneficial effects:

[0253] 1. Risk of can explosion reduced by 90%

[0254] The overflow valve 22 lowers the trigger pressure from 0.8MPa to 0.6MPa to release pressure in advance and prevent physical rupture of the storage tank 7.

[0255] Case: At a well site, a valve blockage caused a pressure surge, resulting in the rupture of the tank in the traditional system. After optimization, only an overflow occurred and no accident occurred.

[0256] 2. Improved reagent recovery rate

[0257] Overflow pipe 21 guides the agent to the recovery tank. In the traditional mode, the agent leaks directly. After optimization, the recovery rate reaches 85%.

[0258] 3. Shortened fault response time

[0289] 2. The coating is cured at high temperature, achieving an adhesion level of 0, and is resistant to salt spray, acids and alkalis.

[0290] II. Corrosion Resistance Test:

[0291] 1. The coating showed no blistering or peeling after 480 hours of neutral salt spray testing, while traditional carbon steel parts showed rust after 240 hours.

[0292] 2. For long-term storage of corrosion inhibitors in pharmaceutical storage tank 7, traditional stainless steel tanks showed corrosion after 3 months, while PTFE-coated tanks showed no change after 24 months.

[0299] Case: A plunger pump 2 in a high-sulfur oil well was scrapped due to corrosion, but continued to operate without being replaced after optimization.

[0300] 2. Zero risk of pharmaceutical contamination.

[0301] The PTFE coating prevents metal ions from dissolving into the reagent. Traditional carbon steel parts leach iron ions annually, but these are not detected after optimization.

[0302] 3. Reduced maintenance frequency

[0303] Traditional components require two anti-corrosion maintenance sessions per year, while the optimized components only require one visual inspection, saving manpower.
