Abstract
The invention discloses a cement-infilling tube device for a bridge plug, which is used for cement infilling operations. The device mainly comprises a cable joint, a cement infilling tube and a cast-iron fitting. The tool is connected in series to the upper part of the bridge plug of an oil pipe by cable operations, the cast-iron fitting is shattered by impact, and cement grey in the cement infilling tube is poured to the upper part of the bridge plug to realize a secondary protection function in plugging in the oil pipe.
Description
Technical field
The present invention is mainly used in oil gas field Operating Pressure scene, after carrying out the operation of bridge plugging oil pipe, for falling the isolated plant of grey job design.
Background technology
In the Operating Pressure process, at first to be lowered to oil pipe bridge plugging oil pipe.This oil pipe bridging plug can be given a shock in oil pipe, the influence of the smooth degree of various medium, temperature and tube wall.Sometimes behind the bridge plugging oil pipe, bridging plug can move up during tool string in tripping out well, this mobile meeting causes the oil pipe shutoff not tight, and more serious consequence will cause bridging plug to fly out and gas blowout accident occurs, and the operating personnel is damaged and the oil field development exploitation is impacted.For preventing that bridging plug from moving and increase the bridging plug sealing, above bridging plug, pour cement paste into, shutoff provides insurance again in the rail.But fall usually in the grey operation because various design defect, in the Operating Pressure environment, often can't realize this function, the sheet that breaks glass of common tool design is realized the pouring plaster, reason owing to well temperature, glass may produce modification in the down-hole, striker is behind bump glass, and it is cracked that glass can not be distributing, and the grey effect of therefore falling is always undesirable.My company has developed a kind of grey instrument that falls voluntarily for this reason, has realized ash work smoothly, the operation effectiveness highly significant.
Summary of the invention
The present invention seeks to finish down smoothly grey operation, this bridging plug ash transporting cylinder device is divided into three parts: cable connector, dress ash tube, afterbody joint.Cable connector can be connected with the wireline operation tool string, and dress ash tube is mainly used to adorn concrete grey, and the afterbody joint adopts the cast iron manufacturing.
Description of drawings
Bridging plug ash transporting cylinder device schematic diagram
The specific embodiment
Below in conjunction with accompanying drawing this invention is described
Among the figure: 1, cable connector; 2, ash transporting cylinder body; 3, concrete grey; 4, short circuit; 5, cast iron joint
When falling grey operation, at first mix the slurry operation by the concrete grey prescription, connect ash transporting cylinder body, short circuit and cast iron joint then, tightly good with pipe wrench, concrete grey is poured into ash transporting cylinder body (noting not damaging the cast iron joint), the stube cable joint, integral body is connected on the cable then, at last ash transporting cylinder is transferred to bridging plug top, transfer fast after confirming to put in place, the cast iron joint bottom the ash transporting cylinder tool string is smashed, cement paste is because action of gravity is poured in the tubing string automatically, cement wait to coagulate, and has reached to fall the purpose of grey operation.
Claims (2)
1. the global design of bridging plug ash transporting cylinder device is in order to satisfy down grey operation, and tool interior is filled concrete grey, and upper design is for stube cable, and bottom cast iron joint is not keep concrete grey excessive and arrive the precalculated position and realize ash.
2. bridging plug ash transporting cylinder device according to claim 1, foot joint are that cast iron processes, and purpose is exactly behind the electric cable bridge plug of contact, can easily it be smashed through impacting, with the concrete grey in the bucket to bridging plug top.
