Description
Technical Field
The utility model relates to an oil drilling technical field specifically is a drilling fluid filter equipment under petroleum well.
Background
Drilling fluid is a circulating flushing medium used in the hole during drilling. The drilling fluid is the blood of the well, also called drilling flushing fluid. The drilling fluid can be divided into clear water, slurry, clay-phase-free flushing fluid, emulsion, foam, compressed air and the like according to the composition. Clear water is the earliest used drilling fluid, does not need to be treated, is convenient to use, is suitable for regions with complete rock stratums and sufficient water sources, and mud is widely used drilling fluid. The drilling fluid is connected to the vertical pipe of the drill floor by a water pump, enters the drill stem through a water hose and a water tap, then is sprayed out from a drill bit at the bottom of the well through a drill bit water hole to carry rock debris at the bottom of the well, returns to the ground along an annular space, is filtered on the ground and then returns to a mud pit, and a circulation passage from the ground to the underground is formed. For a production well, a hydrocarbon reservoir is required to be protected, the yield is required to be improved, and the requirements are all realized by formulating reasonable drilling fluid performance indexes, wherein the plastic viscosity of the drilling fluid is the sum of the internal friction among solid-phase particles, between solid and liquid molecules in the drilling fluid and the flow resistance generated by shearing of the liquid under the laminar flow condition, and the main factors of the plastic viscosity are the number and the size of the solid particles contained in the drilling fluid and the type of clay minerals. In the process of circulating and flowing the drilling fluid, the plastic viscosity is inevitably increased due to the large quantity and fine granularity of solid particles at the bottom of the well. The plastic viscosity of the drilling fluid is too high, so that the flow resistance is increased, the pumping pressure is increased, the discharge capacity is reduced, the bottom hole cleaning effect is poor, the drilling speed is seriously influenced, the sand cleaning and gas descending work is difficult, the 'piston pulling' or drill jamming or pump starting difficulty after drilling is caused, the most effective method for reducing the plastic viscosity is to dilute by water or reduce the solid content by a mechanical sand reducing method, but the existing filtering device can only filter the bottom hole rock debris but neglects the dilution of the drilling fluid, so that the molding viscosity of the drilling fluid is increased, and therefore, the filtering device for the drilling fluid under the petroleum well is provided.
