The downhole high-pressure water jet blockage removal and flowback device independently developed by Dongying Jiuli Petroleum Technology Co., Ltd. has successfully obtained the authorization of a national invention patent (Patent No.: ZL202421386327.2). This device is a downhole tool used for oil and gas field development, mainly aiming to solve the difficult problems of oil reservoir blockage and flowback fluid treatment. By utilizing high-pressure water jet technology, the device can effectively remove the blockages in the oil reservoir and conduct real-time treatment of the flowback fluid, thus realizing the efficient and environmentally friendly development of oil and gas fields. It provides a new technical means for the efficient development of oil and gas fields.

During the development of oil and gas fields, the blockage of oil reservoirs and the treatment of flowback fluids are two major challenges. Traditional blockage removal methods have problems such as low efficiency, high cost, and easy damage to the formation. Improper treatment of flowback fluids will cause environmental pollution. The invention of the downhole high-pressure water jet blockage removal and flowback device provides an effective solution to these two major problems.

This device integrates two major functions: high-pressure water jet blockage removal and flowback fluid treatment, and has the following advantages: 1.High-efficiency blockage removal: By taking advantage of the powerful impact force of the high-pressure water jet, it can effectively remove the blockages in the pores and fractures of the oil reservoir, restore the permeability of the oil reservoir, and increase the oil and gas production.

2.Environmentally friendly flowback: The device is equipped with an efficient built-in filtration system, which can conduct real-time treatment of the flowback fluid, remove the solid particles and harmful substances in it, achieve up-to-standard discharge, and avoid environmental pollution.

3.Safe and reliable: The device is made of high-strength materials and is equipped with multiple safety protection devices to ensure safe and stable operation under harsh working conditions such as high pressure and high temperature.

4.Easy operation: The device has a compact structure and simple operation. It can be quickly lowered into the wellbore, realizing automated operation, reducing labor intensity, and improving operation efficiency.

The successful development of this device is another important achievement of Dongying Jiuli Petroleum Technology Co., Ltd. in adhering to scientific and technological innovation and serving the development of oil and gas fields.

At present, this device has been successfully applied in blocks such as Gudao Oilfield, achieving remarkable economic and social benefits.

In the future, Dongying Jiuli Petroleum Technology Co., Ltd. will continue to increase its investment in research and development, continuously optimize and improve the performance of this device, provide higher-quality technical services for the efficient development of oil and gas fields, and safeguard China's energy security!
