Water Injection Wellhead Design Requirements
Water injection wellhead should be designed in accordance with the following requirements 1. The water injection wellhead should meet the requirements of positive injection, back injection, mixed injection, positive washing, reverse washing, metering oil pressure and casing pressure sampling water. 2. The water injection wellhead needs meet the requirements of well test (such as downhole pressure, temperature, water quantity, downhole sampling, sand surface height and artificial bottom hole). 3. It can also satisfy the requirements of acidification, fracturing, water shutoff, profile control and water absorption profiles. 4. According to the requirements determined by the water wells, the water injection wellhead should have the following characteristics: high strength, long life, work pressure greater than the formation of the rupture pressure, light quality, small size, simple flow, and to minimize the dead water pipe section. 5. The installation of the water inject...
