Description
Technical field
The utility model be related to oil-water well application in petroleum industry take out drag for sand instrument carry out pit shaft sand removal operation technology neck
A kind of domain, and in particular to spin drilling type pit shaft rramming device.
Background technology
Sand production is one of subject matter for facing in domestic sandstone oil reservoir recovery process, has a strong impact on and restricts
The normal production of crude oil and the raising of economic benefit.Especially for the oil field for being in middle and later periods exploitation, by well water high,
The big and individual well high intensity of lamination drop puts the impact of poor extract and the unfavorable factors such as the voidage-injection imbalance of pay interval, formation depletion,
Negative pressure is serious, and oil well generally seriously shakes out.
Sand bucket negative pressure sand bailing process technology be by a kind of wide variety of side for removing pit shaft settling sand in each oil field
Method.Sand bucket is made up of two cores, i.e., the sand bucket cylinder assembly at top and bottom drag for abrasive cone (also known as rramming device).Negative
Pressure sand bailing process tubular column structure is followed successively by from top to bottom：Power oil pipe, sand bucket cylinder assembly, stores up sand oil pipe, drags for abrasive cone, using anti-
Put the continuous pumping mode that puts to enter the settling sand pumping in pit shaft and be deposited in storage sand oil pipe on multiple.This drag for sand technology
Have the characteristics that technical maturity, simple to operate.But, when the top of pit shaft settling sand post, i.e. sand face is harder, forms hard sand lid
After (face), traditionally drag for abrasive cone and just hard sand lid cannot be smashed to pieces using what vertically pressuring method worked on sand face, most
Cause pumping repeatedly eventually all nothing drilling depth, drag for sand failure.
Therefore, people again devise one kind on the basis of traditional sand bailing process and can transmit well head moment of torsion, whole with making
The individual sand bucket for dragging for sandpipe post rotary drilling function.The plunger pull bar of this drilling type sand bucket is tied using deltiod or polygon
