Abstract
The utility model discloses a convenient drilling mud blowout prevention box, which is provided with a cylinder, wherein the cylinder consists of two half cylinders; side edges of the half cylinders are provided with hinges, and the other side edges of the half cylinders are provided with manual locking members; combined edges of the two half cylinders are provided with sealing adhesive tapes and pressing plates; the upper ends of the two half cylinders are provided with semicircular sealing rubber rings and rubber ring fixing members respectively; the sealing rubber rings and the rubber ring fixing members are matched with an aperture required for drill string sealing; flow guide funnels are formed in the inner sides of the lower ends of the two half cylinders; and lower ports of the flow guide funnels lead to lower space outside the cylinder. Reinforcing ribs are arranged on the inner sides of the two half cylinders; the upper ends of the half cylinders are provided with lifting rings respectively; and lifting handles are arranged on the outer sides of the upper parts of the half cylinders. The convenient drilling mud blowout prevention box is applicable to preventing blowout of drilling mud during disassembly of a drilling tool, and the mud is recovered and utilized. The convenient drilling mud blowout prevention box has the advantages of rational structure, light weight, flexibility in operation, low cost and good blowout prevention effect.
Description
Technical field
The utility model relates to a kind of petroleum drilling technology field, is specifically related to a kind of portable drilling mud blowout prevention box, is used for dismounting drilling tool process and prevents mud splash pollution platform and operator, and make drilling mud obtain reclaiming and utilizing.Characteristics with light, flexible, safety, cleaning, saving.Be applicable to 2

Technical background
At present, domestic petroleum drilling technology field spray arrester commonly used roughly is divided into three kinds: first kind, to make with iron sheet, and wall ratio is thinner, and quality is light, and structure is perfect inadequately, and the problem of existence is, life cycle is short, will be out of shape once colliding with and can not use.Second kind, with steel pipe or foundry goods welding fabrication, quality is heavy, and bottom sides has special mozzle, needs to connect sebific duct and reclaims drilling mud, and the problem of existence is: weight is big, and the restriction of active receiving mozzle is operated not nimble.The third: external import, non-metallic material uses flexible, convenient.The problem that exists: price height.Therefore, need to propose a kind of more reasonable structure, more suitable, cheap mud blowout prevention utensil.
The utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and proposes a kind of portable drilling mud blowout prevention box, and this blowout prevention box structure is improved rationally, and quality is light, and is easy to use, flexible operation, and cost is low, and anti-drilling well mud ejection is effective.
The technical solution adopted in the utility model is: portable drilling mud blowout prevention box, be provided with cylindrical shell, it is characterized in that: described cylindrical shell is that half cylindrical shell of two symmetries constitutes, the side of this two and half cylindrical shell is provided with the hinge that flexibly connects two and half cylindrical shells, another side outside of two and half cylindrical shells relative with this hinge place side is provided with manual locking spare, the edge that two and half cylindrical shells combine is provided with the pressing plate of sealing joint strip and fixing seal adhesive tape, the upper end of two and half cylindrical shells is respectively equipped with the O-ring seal of semi-round ring shape and compresses the cushion rubber fixture of sealing cushion rubber, and its bore and drill string seal required bore and match; Be provided with the synthetic water conservancy diversion funnel of halved body in the inboard, lower end of two and half cylindrical shells, this water conservancy diversion funnel lower port is led to the outer below of cylindrical shell.
The utility model further improves and the additional project of enforcement is:
Inboard at two and half cylindrical shells is provided with reinforcing rib.
Be respectively equipped with the drop handle of lifting usefulness in the upper end of two and half cylindrical shells.
Be provided with handle in two and half cylindrical shell upper outside.
The use of portable drilling mud blowout prevention box of the present utility model: when drilling rod pulls out of hole, before button is dismantled, this portable drilling mud blowout prevention box is placed on the platform, manual locking spare is opened, two and half cylindrical shells of blowout prevention box are separated, place the box cupling place of drilling rod up and down, close again, manual locking spare is placed the lock position, dismantle the drilling rod button, the mud ejection enters in the blowout prevention box chamber, because there is the O-ring seal sealing blowout prevention box upper end, so mud can only flow into well head by the water conservancy diversion funnel of blowout prevention box lower end.
The beneficial effects of the utility model: the utility model portable drilling mud blowout prevention box, structure improve rationally, have removed extension tube attached, and be easy to use, and rotational angle arbitrarily during operation is unrestricted; In light weight; Folding is flexible, manual locking device has been realized synchronous on-off one time, and the utility model can be applicable to the drilling rod trip-out operation of multiple different size, and mud is reclaimed and utilization again, make trip-out operation hommization more simultaneously, operator and rig floor are cleaned more.
