TECHNICAL FIELD

[0001] The utility model belongs to oilfield exploitation technical field, concretely relates to a kind of water discharge pipeline for double-pump cementing sled. BACKGROUND

[0002] Modern oilfield exploitation is often accompanied by a large amount of water and gas, with the increasing awareness of environmental protection in society, the impact on the environment during oilfield exploitation must be strictly controlled. Double-pump cementing sled is equipped with two high-pressure mud pumps, which can provide sufficient pressure and flow at the same time to ensure the effective injection of cementing mud.

[0003] During the use of double-pump cementing sled, a separator is usually used to effectively manage and treat the mixture of crude oil, natural gas and associated water. If these associated substances are not treated, they will affect the quality and efficiency of oil production. The separator can effectively separate the oil in the water, ensuring that high-quality crude oil is effectively recovered, not only improving overall production efficiency, but also making the water discharged into the environment meet environmental standards and reducing pollution to the ecosystem.

[0004] If the associated water in the separator is not discharged in time, it will occupy the space inside the separator, affecting the normal work of the separator and reducing the separation efficiency. Long-term water accumulation will increase the load of the separator, causing internal corrosion or other mechanical failures and shortening the service life of the equipment. However, the existing separator usually discharges a large amount of accumulated water at one time when draining, which may cause pressure fluctuations or water hammer phenomenon of the equipment, causing damage to the separator and its auxiliary equipment.

[0005] In summary, the existing separator has the problem of large amount of water discharge at one time when draining, which may cause equipment damage. UTILITY MODEL CONTENTS
