Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks broken section structural representation.
coding in accompanying drawing is respectively: 1 is top connection, and 2 is upper cone, and 3 is cylindrical shell, and 4 is lower contact, and 5 is gland, and 6 is glass plate, and 7 is longitudinal hole, and 8 is elasticity lance, and 9 is impact head, and 10 is positive stop lug boss, and 11 is back of the body cap, and 12 is mud grouting mouth.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this note ash bucket comprises top connection 1, upper cone 2, cylindrical shell 3 and lower contact 4, the lower outside of top connection 1 and the upper inner of upper cone 2 are fixed together, the lower end of upper cone 2 and the upper end of cylindrical shell 3 are fixed together, the lower inside of cylindrical shell 3 and the upper outside of lower contact 4 are fixed together, gland 5 is installed with at the lower outside of lower contact 4, the bottom of gland 5 is positioned at the below of lower contact 4 bottom, through hole is had in gland 5 bottom, glass plate 6 is installed with inside gland 5 bottom, gland 5 below glass plate 6 is fixed with the striker that upwards can crash glass plate 6, upper cone 2 is distributed with the longitudinal hole 7 that at least two longitudinal directions are through, at least one mud grouting mouth 12 communicated with cylindrical shell 3 inside is had on cylindrical shell 3 top.When Oil Field operation, first, in cylindrical shell 3, the cement paste of some is injected by mud grouting mouth 12, special joint is used to be linked together by top connection 1 by the cable of the utility model and wireline operation car, then, the utility model is improved lowering velocity after certain depth until the utility model and bridging plug upper end are clashed into, now, the left part of striker can be bent upwards, striker left part can impact on a glass plate 6, glass plate 6 is smashed by striker, then, the utility model is carried at a high speed, the cement paste of the utility model inside is flowed out smoothly by through hole and rests on the above well section of bridging plug smoothly, cement paste is finally set in the above well section of bridging plug and completes shutoff wellbore operations, the utility model is carried in continuation until the utility model proposes well head.Cement paste can be injected into the above well section of bridging plug by setting of the present utility model accurately, improves the reliability of pit shaft shutoff, ensures carrying out in order of follow-up underground work, improves operating efficiency.
according to actual needs, above-mentioned note ash bucket can be made further optimization and/or improvements:
as shown in Figure 1, striker comprises and has flexible elasticity lance 8 and impact head 9, and impact head 9 is fixedly mounted on the upper end, bottom of elasticity lance 8, skewed in lower-left upper right of elasticity lance 8.In the process that the setting of elasticity lance 8 can collide at elasticity lance 8 and bridging plug, it is bending that elasticity lance 8 occurs upwards, make impact head 9 and glass plate 6 that percussion occur, thus shattered glass plate 6, further ensure and cement paste is injected into the above well section of bridging plug accurately, further increase the reliability of pit shaft shutoff, ensure carrying out in order of follow-up underground work, further provide operating efficiency.
as shown in Figure 1, the top of glass plate 6 and the bottom of lower contact 4 are fitted together.The setting that the top of glass plate 6 and the bottom of lower contact 4 are fitted together can improve the success rate of striker shattered glass plate 6.
as shown in Figure 1, be fixed with positive stop lug boss 10 outside the lower contact 4 above gland 5, bottom and positive stop lug boss 10 top of cylindrical shell 3 are fitted together, and be installed with and carry on the back cap 11 outside the lower contact 4 between gland 5 and positive stop lug boss 10.The setting of positive stop lug boss 10 further increases the success rate of striker shattered glass plate 6.
as shown in Figure 1, the top of upper cone 2 is up-narrow and down-wide frustum; Or/and, be circumferentially evenly distributed with the through longitudinal hole 7 of four longitudinal directions upper cone 2 is same.
as required, the lower end of upper cone 2 and the upper end of cylindrical shell 3 are fixed together by welding, and the lower inside of cylindrical shell 3 and the upper outside of lower contact 4 are fixedly installed togather by screw thread, are installed with gland 5 at the lower outside of lower contact 4 by screw thread.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
