Description
Technical Field
The application relates to the technical field of weighting and slurry preparation operation, in particular to a weighting and slurry preparation sled of a drilling site solid control system.
Background
The mud is circulating liquid in the drilling process, impurities such as rock cutting at the bottom of the well are discharged out of the well in a circulating way, meanwhile, a drilling tool and a drill bit under the well are cooled and lubricated, and the circulation, configuration, storage and transportation of the mud in the drilling process are realized by a mud pump and a solid control system. The specific gravity of the mud is required to meet the construction process requirements of drilling engineering, and the excessive specific gravity of the mud causes the mud to circulate in the shaft to require larger pressure, so that the load and the abrasion of the mud pump are increased. If the specific gravity of the slurry is too small, effective circulation cannot be formed between the well bore and the slurry solid control system, and solid impurities such as rock scraps in the well bore cannot be returned to the ground, so that abrasion of a drilling tool in the well bore is increased; another key problem is that when the formation pressure is too high, the mud with a lower specific gravity cannot effectively balance the formation pressure, thereby bringing about a great potential safety hazard.
In the drilling process, if the underground formation pressure is too high, the potential safety hazard of blowout is easily caused (such as hydrogen sulfide gas generated during blowout has toxicity, has extremely high diffusivity, is inflammable and explosive, and is extremely easy to cause burning damage of various drilling equipment on a drilling site), so that when the increase of the underground formation pressure is detected in the drilling process at present, the specific gravity of slurry is increased by preparing weighting slurry (weighting slurry raw materials such as barite powder and the like are added into a slurry tank of a solid control system), and the harm caused by the underground formation pressure is overcome and restrained, thereby avoiding the blowout phenomenon.
At present, in the process of preparing the weighting slurry, a ton bag body loaded with weighting slurry raw materials is usually hoisted to the top of a slurry tank of a solid control system in a hoisting mode, then the bag body is cut and then subjected to direct falling of raw material slurry, and the raw material slurry falls into the slurry tank and is fully stirred and mixed by a stirrer in the slurry tank, so that the purpose of weighting the specific gravity of the original slurry is achieved. After the weighted mud falls into the solid control system, the added weighted mud cannot obtain a good mixing effect, so that imbalance of the specific gravity of the mud is caused, after the mud is circulated to the bottom of the well, the mud with increased specific gravity can well inhibit the underground stratum pressure, and after the mud without being weighted is circulated to the bottom of the well, the underground stratum pressure can not be balanced, so that fluctuation of the underground pressure is caused, and the potential safety hazard of blowout still exists.
Meanwhile, the existing process of manually hoisting and adding the raw materials for preparing the weighted mud also has the problems of difficult operation (particularly, such as cutting operation in the hoisting state of the bag body), pollution throwing when the raw materials fall, and the like.
Disclosure of Invention

Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below with reference to the accompanying drawings and examples.
Referring to fig. 1-5, a mud-mixing skid is added to a drilling site solid control system, the mud-mixing skid comprises a skid plate platform 1 placed on the ground on one side of a mud tank 10, and the skid plate platform 1 can be lifted to realize transportation so as to perform the mud-mixing operation of the mud tank 10 with weight, thus having better use flexibility.
In order to finish the weighting slurry-mixing operation of the slurry tank 10, a slurry-mixing mechanism communicated with the slurry tank is arranged on the skid plate platform 1, and mainly comprises a sand pump, a mixing hopper 2 and a pipeline communicated with the slurry tank 10. Through adding the thick liquids that need the counter weight into compounding funnel 2, under the driving effect of sand pump, inhale the thick liquids with even volume vacuum and realize aggravating the joining in marriage thick liquids operation in mud jar 10, avoid at present adding whole bag aggravating mud directly to solid in the control system, can not realize aggravating the effective mixing of mud and cause the problem of pressure fluctuation in the pit.
Because the slurry tank is large in volume, a large amount of slurry is usually added during heavy slurry preparation, and the slurry is usually in the form of bagged ton (i.e. the weight of each bag of slurry is about one ton), so that it is difficult for on-site staff to add the slurry in the slurry bag with large weight into the mixing hopper, and therefore, in order to solve the problem, a hoisting mechanism capable of being communicated with the mixing hopper 2 is arranged at one side of the slurry preparation mechanism.
As shown in fig. 1, the lifting mechanism is a suspension arm 4 disposed on a skid plate platform 1 at one side of a mixing hopper 2, and the suspension arm 4 includes a base 41, a rotating rod 42, a cross beam 43, a chain electric hoist 44 capable of sliding on the cross beam, and a lifting hook (not shown in the figure). During operation, the slurry ton material bags are transported to the ground outside the skid plate platform 1 through the vehicle body to be stacked and placed, during hoisting, the slurry ton material bags outside the skid plate platform 1 can be lifted through the lifting hooks to rotate and vertically correspond to the mixing hopper, after the bag body is opened, slurry in the bag body falls into the mixing hopper 2, and the slurry can be conveyed into the slurry tank 10 through the driving of the sand pump to realize weighting and slurry distribution.
After the bag body is subjected to the splitting operation under the lifting state of the slurry ton material bag, a large amount of slurry can be poured out, so that a large amount of slurry is easy to cause that the slurry cannot be conveyed through the mixing hopper 2 in a short time, the slurry is further caused to be thrown to the waste outside the mixing hopper, and meanwhile, slurry is thrown and contacted with an operator, so that a bag breaking device for breaking the slurry bag body under the lifting state is arranged in the mixing hopper 2.
Specifically, as shown in fig. 4, the bag breaking device is bag breaking blades 3 arranged on the inner wall of the mixing hopper 2 along the axial distance. In the process of discharging the slurry ton material bag through the lifting hook, the bottom side of the slurry ton material bag is gradually contacted with the bag breaking blade 3 arranged on the inner wall of the mixing hopper, the slurry ton material bag is cracked through the bag breaking blade 3, and then the slurry in the slurry ton material bag falls into the mixing hopper 2 for conveying. Through this broken bag blade 3 to the fracture operation of substitution, can realize the gradual fracture of substitution and the slow whereabouts of ground paste in compounding funnel 2, the ground paste that the ground paste was poured in a large number when solving artifical fracture throws extravagant problem to and the ground paste is easy with the problem of operating personnel contact pollution when artifical fracture, and can reduce the thick paste dust pollution that produces when the ground paste emptys.
The bag breaking blade 3 is generally protruded in the outer wall of the mixing hopper 2, and is easy to cause a clamping stagnation of falling of the bag body after contacting with the bag body in the set state, and further continuous cracking of the bag body and smooth falling of slurry cannot be realized, so that in order to solve the problem, as shown in fig. 4, the bag breaking blade 3 is of a triangle structure gradually increasing downwards along the surface of the mixing hopper 2. The structure makes the top of the bag breaking blade 3 flush with the inner wall of the mixing hopper 2, and solves the problem that the top of the bag breaking blade 3 is easy to replace to cause clamping stagnation. The width of the downward bulge of the bag breaking blade 3 is gradually increased, so that the bag breaking blade is closer to the outer wall of the bag body, and after the bag body falls down and contacts with the bag body, the bag body can be smoothly cracked, and further the smooth falling of slurry in the bag body is realized.
The opening replaced by the splitting of the bag breaking blade 3 is gradually increased along with the gradual downward movement of the bag body, so that the falling of slurry is accelerated, and after the bag body is supported by the inner wall of the mixing hopper 2 in a contact manner, the bag breaking blade 3 stops the splitting operation of the bag body, so that the split opening is not easy to be oversized, the flow of slurry falling is ensured, and the problems of mistransportation and slurry scattering caused by excessive increase of the flow are avoided.
Because the suspension arm is a structure capable of rotating freely horizontally, in the process of vertically corresponding and blanking the bag body and the mixing hopper 2, uneven stress of the bag body can cause horizontal rotation of the suspension arm, and then the bag body can be moved to the outer side of the mixing hopper 2, namely, slurry is thrown outwards, so that in order to solve the problem, as shown in fig. 5, a locking mechanism for vertically corresponding positioning of the slurry bag body and the mixing hopper 2 is further arranged on the lifting mechanism, the concrete structure comprises a positioning insert rod 421 penetrating through a rotating rod 42 of the suspension arm 4, a jack 411 of the positioning insert rod 421 is arranged on a base 41, the suspension arm 4 is embedded into the state vertically corresponding to the mixing hopper 2, and the bag body is inserted into the jack 411 under the state vertically corresponding to the mixing hopper 2, so that the lifting position of the bag body is locked, and the problem of throwing slurry caused by separating from the mixing hopper 2 due to rotation of the bag body after the bag body is cracked is avoided.
The principle of the application is as follows: when the slurry tank 10 is subjected to weighting and slurry mixing operation, the skid plate platform 1 is integrally lifted to one side of the slurry tank 10 and is communicated with the slurry tank through a pipeline, and meanwhile, a truck body is used for transporting slurry ton bags and is piled on one side of the skid plate platform 1. When the feeding operation, the slurry ton material bag outside the skid plate platform 1 can be lifted by the lifting hook of the suspension arm 4 and then rotated, the slurry ton material bag vertically corresponds to the mixing hopper 2, the positioning inserting rod 421 is inserted into the inserting hole 411, the locking of the lifting position of the bag body is realized, then the bag body is downwards moved by the endless chain electric hoist, the bottom side of the slurry ton material bag is gradually contacted with the bag breaking blade 3 arranged on the inner wall of the mixing hopper in the process of downwards placing the slurry ton material bag, the slurry ton material bag is cracked by the bag breaking blade 3, and then the slurry in the slurry ton material bag falls into the mixing hopper 2 for conveying.
The foregoing has outlined and described the basic principles, main features and advantages of the present application. Various changes and modifications may be made to the present application without departing from the spirit and scope of the application, and such changes and modifications fall within the scope of the application as hereinafter claimed.
