Description
Technical Field
The utility model relates to a fluid circulation device's test system, especially an oil gas drilling circulating device's test system belongs to oil and gas engineering or mechanical engineering technical field.
Background
In the process of drilling a sandy stratum, the power drilling tool can not normally operate due to water hole blockage caused by silt and the like. When the drilling fluid can not normally circulate, the drilling fluid can flow out from the bypass of the drill column by using the circulation nipple, so that the situations such as abnormal pressure building of the downhole tool are avoided. The advantage of a circulation sub is that it behaves as a small section of drill string when the drilling fluid is normally circulating; when the drilling fluid can not normally circulate, the normal circulation of the drilling fluid can be completed without tripping the drilling rig, so that the operation efficiency is improved, the production cost is reduced, and the drilling risk can be reduced. Before the circulation nipple enters the site, the function of the circulation nipple must be tested, so that the circulation nipple can work normally. The utility model aims at providing a drilling fluid circulation test system's design.
