SAFETY TESTING OF THREE HIGH GAS FIELDS HIGH-PRESSURE MANIFOLD
Now Chinese Three high gas fields are in-depthryexploited. As a reliable and necessary equipment, high-pressure manifold are used to control Kick and pressure. The safety and reliability of high-pressure manifold has been increasingly high attention. In the drilling operation, the high-pressure manifold includes choke manifold and killing manifold. Through die adjustable throttle valve, the high-pressure manifold can put some back pressure, and control wells or changing the flow of the fluid flow line. During the three high gas field drilling and completing, firstly, the presence of high-medium containing H2S/CO2, so that high-pressure manifold are prone to corrosion, stress corrosion or hydrogen embrit-tlement faihire; Secondly, due to Slurry erosion of solid particles in the role of manifold wall is likely to rapidly thinning. Once the high-pressure manifold become invalid, it is easy to lead a blowout, poisoning, explosion and otter accidents. So the study of high-pressure manifold s very important to three-high gas fields exploitation. The testing of high-pressure manifold is non-destructive testing, and it includes pressure testing, ultrasonic testing and magnetic memory testing. The above methods have their own advantages, so it is necessary for different situations using different methods. More fully grasp the scope of application of three kinds of detection methods are conducive to high-pressure manifold we have carried out targeted testing, and thus we can discover the manifold defects fast, and ensure that three high gas production safety.
