Description
Technical field
The utility model relates to a kind of drillable waterpower pulse turbine well cementation vibrator, is mainly used in oilfield technology field.
Background technology
In drilling process, under to enter protective casing be easily collapsing to well intermediate wells section, leakiness, high pressure, the stratum such as saliferous, play the effect of isolation stratum and protection well bore.
Because the effect of protective casing is special, also very high to its cementing requirements, under enter drillable waterpower pulse turbine well cementation vibrator, guarantee cementing quality, drillable waterpower pulse turbine well cementation vibrator can improve displacement efficiency, eliminates the bubble in cement liquid, forms intact cement sheath, thus shorten the Hou Ning time, oil, gas, water breakthrough time Hou Ning " weightlessness " after preventing from cementing the well.Being conducive to the cementing strength at raising two interfaces, is one of effective method improving cementing quality.
After intermediate casing cementing completes, need creep into continuously, the drillable waterpower pulse turbine well cementation vibrator be arranged on bottom protective casing must be carried out milling, until grinding completes, form through hole.Be convenient to subsequent well.
Therefore special requirement is had to the drillable waterpower pulse turbine well cementation vibrator be arranged on bottom protective casing: 1) drillability: internal construction can grinding, can milling; 2) vibratility: the reasonability of eccentric block material, quality, structure.
But existing vibrator generally adopts steel material to make, in use procedure, find that its drilling performance is not satisfactory, if and discovery adopts the manufacture of drilling material, due to the relation of density of material, eccentric effect is not satisfactory again, and in use, normal defence line eccentric block is wherein easily worn part, and existing vibrator is when eccentric block damages, is difficult to realize maintenance, causes scrapping of vibrator, wasting phenomenon is very serious, therefore needs to be improved.
Utility model content
The utility model is for above-mentioned defect, and object is to provide the drillable waterpower pulse turbine well cementation that a kind of structure is simple, result of use is good vibrator.
The technical solution adopted in the utility model is for this reason: the utility model comprises urceolus (1) described urceolus (1) and is separated into some regions by Support tray (2), turbo blade (3) is respectively arranged with in each region, eccentric block (4) is provided with in a region wherein, then interval eccentric block (4) is set closing in Two Areas, arrange with this, each eccentric block (4) homonymy is arranged on shell side; Described eccentric block (4) point two-layer setting, its ectomesoderm is brass part (41), and internal layer is aluminum casting (42).
Described eccentric block (4) is circular arc, and brass part (41) and aluminum casting (42) pass through rivet.
Described two Support tray up and down (2) being provided with eccentric block (4) region offer the groove of accommodating eccentric block (4).
Described groove is through hole, Support tray (2) sidepiece of correspondence is provided with the side channel be communicated with described groove, be provided with in described side channel to extend in groove and also form the gripper shoe supported described eccentric block (4), be provided with stria inside described groove, described gripper shoe extends in stria.
Described each Support tray (2) is provided with through hole, and described through hole is arranged between eccentric block (4) and turbo blade (3).
Be provided with the mandrel supporting described Support tray (2), turbo blade (3) between described each Support tray (2), described mandrel is arranged on each Support tray (3) middle part, and described mandrel is solid setting near the side of eccentric block (4), and opposite side is hollow setting.
The utility model has the advantages that: 1) adopt can the material (cast aluminium and brass) of drilling for the utility model, and therefore drilling performance is effectively ensured, and eccentric block adopts composite structure, the weight of eccentric block is met the requirements, ensure that eccentric vibrating effect; 2) eccentric block of the present utility model is arranged to dismountable form of structure, like this when eccentric block is damaged, can be dismantled easily, and maintenance or replacing, this avoid because eccentric block damage causes vibrator to scrap the defect of waste; 3) the utility model is by groove fixed eccentric block, and its form is simple, but can reach good fastening effect, in use can not loosen, ensure that the service behaviour of vibrator; 4) the utility model arranges mandrel, mandrel the axiality that first ensure that each parts is set, second the utility model has specially made concrete restriction to the structure of mandrel, wherein by solid for its side near eccentric block setting, and the hollow setting of opposite side, so also can play certain wobbler action, suitably can reduce the thickness of eccentric block, the utility model utilizes existing parts to achieve eccentric effect, therefore the utility model structure can be made more compact, and reduce the use of material, reduce use cost.
