Description
Technical Field
The invention belongs to the technical field of petroleum drilling, and particularly relates to a three-way ball valve type multifunctional drilling circulation nipple.
Background
With the continuous development of oil and gas exploration and drilling technology, the proportion of a large displacement well and a horizontal well in a drilling well type is higher, the well bore size and the discharge amount of drilling fluid are reduced along with the increase of well depth and well inclination, and rock debris in a shaft is continuously deposited on the bottom edge of the well bore to form a rock debris bed, so that a series of underground complex problems are caused, and the construction efficiency is seriously influenced. At present, most of the borehole cleaning tools at home and abroad adopt a method of destroying a rock debris bed by cutting with a tool body cog, but the operation cannot fundamentally solve the problem of rock debris deposition. Limited by technology, relatively few tools are available for wellbore cleaning using high-displacement jetting.
Lost circulation is one of the common downhole complications in drilling operations, and has existed for a long time and has not been solved effectively. When the leakage is serious, the plugging agent with larger particle size is often needed for plugging, but the drilling-following instruments of the drilling tool, such as rotary guide, turbine, screw and the like, cannot pass through the plugging particles, so that the drilling tool needs to be replaced by pulling out the drilling tool to perform plugging operation, and the speed of the drilling operation is seriously limited by pulling out the drilling tool for plugging for many times. In recent years, most of the leakage stoppage while drilling tools appearing at home and abroad perform leakage stoppage operation by throwing a ball starting tool at a wellhead, and have the defects of difficult operation, limited starting times, high failure rate and the like.
In addition, blowout is a serious accident which endangers the safety of offshore operation in the drilling process, normal drilling operation is disturbed to damage underground oil and gas resources, and the oil and gas wells are scrapped and drilling devices are damaged to cause environmental pollution and huge economic loss. If the well control treatment can be rapidly carried out after the inner annulus and the outer annulus of the tubular column are sealed in the initial stage of well kick, the well control efficiency can be greatly improved, and the well blowout accident rate is reduced. At present, when a kick occurs at home and abroad, a method of manually installing a cock at a wellhead and then closing the cock is basically adopted to finish the drill rod sealing, and the method has the disadvantages of inconvenient operation, long processing time and low safety.
