Abstract
The utility model relates to an underground multifunctional sand washing processor which can be used for breaking gravel and fishing objects dropping into a well in a sand washing process. The processor comprises a washing pipe and a barrel body. A fishing piece is welded on the outer wall of the washing pipe, the upper portion of the washing pipe penetrates the barrel body in a sleeve mode, a lower control ring and an upper control ring are installed on the inner portion and the outer portion of the barrel body respectively through threads on the upper portion of the washing pipe. In a sand washing process, when dropped objects like rubber sheets, small dropped objects or large cement blocks are found at the well bottom and cement is formed on the wall of a sleeve, the well can be subjected to back washing directly, fishing and sand washing are conducted simultaneously, and the objects are broken and pass through the back washing well to be circulated to the ground. The processor is simple in structure, solves the problem of sand washing blocking, is capable of conducting sand washing and fishing simultaneously, saves construction procedures, improves operation success rate of the next sand washing pipe column and reduces sand washing operation cost.
Description
Technical field
The utility model relates to the underground sand-wash power tool of petroleum industry, a kind of underground multifunctional sand washing processor particularly, can be in sand washing process crushing gravel, salvage trouble of lost tool in hole.
Background technology
Due to sand production in oil, in oil extraction process, gravel can be accumulated in pit shaft, affects the swabbing operation of oil well pump.If use conventional sand flushing tool sand washing, because the elbow latus rectum of water tap is little, in work progress, easily block water tap, cause construction inconvenience; If shaft bottom also has rubber class junk or small falling object or runs into large cement block and casing wall has just normally sand washing of cement, easily cause and suppress pump, damage the rough sledding such as sand-flushing pipe column.And when horizontal well recoil sand, large particle diameter gravel is difficult to take ground to by circulation, after gravel rises to certain altitude, just in tubing string, roll and do not continue rising, cannot be circulated to ground, very easily stop up tubing string and cause and construct unsuccessfully.If on carry sand-flushing pipe column and also can cause environment pollution, increase difficulty of construction.If the casing damage of oil well, the gravel of piling up in pit shaft can cause sand washing difficulty, water blockoff is leading or sand washing repeatedly, has increased sand washing operating cost.Production scene needs a kind of device of can limit trimming processing pit shaft.
Summary of the invention
The purpose of this utility model is to provide a kind of underground multifunctional sand washing processor, sand washing on one side on one side, clears up pit shaft, saves working procedure, facilitates sand washing, avoids occurring in sand washing process the phenomenon of sand card and trouble of lost tool in hole obstruction sand washing operation.
Technical solution of the present utility model is: a kind of underground multifunctional sand washing processor comprises washing pipe and cylindrical shell, sheet is salvaged in the outer wall welding of washing pipe, washing pipe top is set in cylindrical shell, and lower gate ring and upper gate ring are arranged on respectively the inside and outside of cylindrical shell by the screw thread on washing pipe top.By washing pipe and the sand washing on one side of salvaging sheet, one side, process gravel and junk in pit shaft.
Compared with prior art, the beneficial effect of this instrument is:
1, this instrument, in sand washing process, has rubber class junk or small falling object if run into shaft bottom, or has large cement block and casing wall to have the situation of cement, direct anti-flushing well, limit salvaging limit sand washing, it is broken after by anti-flushing well, be recycled to ground.
When 2, horizontal well recoils sand, major diameter gravel can directly enter salvages chamber, can there is not gravel and rise to the phenomenon of just rolling after certain altitude and not continuing to rise in tubing string, prevent from stopping up tubing string and cause and construct unsuccessfully, avoid proposing the problem of environmental pollution that sand-flushing pipe column causes midway.
3, run into the oil well of casing damage, the gravel that sand washing can be taken out of temporarily remains in to be salvaged in chamber, takes well head during lift pipe string out of again, has avoided sand washing difficulty, water blockoff is leading or the phenomenon of sand washing repeatedly occurs.
The utility model is simple in structure, has solved the sand washing problem that is hampered, and can salvage on sand washing limit, limit, saves working procedure, has improved the job success ratio of next time sand-flushing pipe column, has reduced sand washing operating cost, has obvious economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of the utility model of accompanying drawing, be described in further detail: a kind of underground multifunctional sand washing processor comprises washing pipe 2 and cylindrical shell 5, sheet is salvaged in the outer wall welding of washing pipe 2, washing pipe 2 tops are set in cylindrical shell 5, and lower gate ring 4 and upper gate ring 1 are arranged on respectively the inside and outside of cylindrical shell 5 by the screw thread on washing pipe 2 tops.Salvaging sheet comprises salvaging every page 8 and spiral and drags for page 3, and salvage every page 8 and spiral and drag for the outer wall that page 3 is all welded on washing pipe 2, salvaging is plate bodys every page 8, is at least provided with one, and its external diameter is greater than the external diameter that spiral drags for page 3, is welded on the top that spiral drags for page 3.Salvaging can be dragged for spiral page 3 every page 8 and be cut off with the salvaging chamber 9 that cylindrical shell 5 forms, and makes fully to pile up in junk Ci space
.on the body of washing pipe 2, in spiral, drag for page 3 interval and be provided with hydrophthalmia 7.Washing pipe 2 front ends are conical pipes, and alloy 6 is ground in its outer wall welding, can grind broken trouble of lost tool in hole.
Before job execution, on the washing pipe 2 of this instrument, connect safety joint, safety joint top connects oil pipe, G.I.H, in well, there is rubber class junk, can anti-circulation well cleanup, rubber class junk and bottom bulky grain gravel are rinsed and uply by spiral, drags for page 3 and enter and salvage chamber 9, if this instrument runs into large junk or bulky grain gravel while salvaging, can be by rotation sand-flushing pipe column by grinding alloy 6 by its fragmentation, by anti-flushing well, rushed to salvaging chamber 9 and temporarily stored again, little gravel can be entered in oil pipe chamber and be returned out well head by hydrophthalmia 7.
