Abstract
The invention relates to a sedimentation treatment device for impurities of oil well operation. Sand can be discharged after trias oil layers go into operation for multiple layers, so that sand setting pockets of oil wells rise, after shafts do not have liquid, submergence of oil well pumps is not enough, problems of breakage of oil stems, tripping and jamming of the pumps are easily caused due to over long dry abrasion time of the oil stems, accordingly, sand needs to be flushed away and drills need to be cleaned before oil well operation, but operational water consumption is higher during construction, well fields mainly depend on manual operation, and cleaning degree of circulation backward flowing of wellheads is not enough. By the aid of an inclined sand separating plate and a sand slipping plate which are arranged on the sedimentation treatment device, sand and stones of oil discharged from oil wells are effectively filtered and subsided, filter holes with gradually reduced diameters on the inclined sand separating plate strengthen filter effect, and engineering difficulty of sand flushing and drill cleaning during operation is really resolved. The sedimentation treatment device is low in water consumption and simple in construction, and effectively reduces production and operation costs.
Description
Technical field
The present invention relates to a kind of oil well operation impurity sedimentation treating apparatus.
Background technology
After Triassic system oil reservoir was gone into operation two to three years through fracturing; Proppant and other material such as sand grains, mud, cement, mechanical admixture etc. can be along with the cracks of rock in most of stratum; Carried by liquid and air-flow and to get into pit shaft simultaneously; Cause oil well sand setting pocket constantly to rise, even bury oil reservoir hole section; More serious is that pit shaft does not have liquid level, and the oil well pump submergence is not enough, and in process of production, the phenomenon of disconnected bar, dropout and holddown takes place beam hanger dry grinding overlong time easily, has a strong impact on the normal operation of oil well.Therefore, oil well generally can carry out artificial prospect pit before operation, thereby calculates the position of the face that shakes out, and carries out sand washing then, sweeps brill.Yet sand washing, the construction of sweeping brill exist a lot of drawbacks, and be bigger like the operation water consumption; Operation that the well site mainly adopts that manual work is digged pit etc.; It is not enough that cleannes are poured in down a chimney in well head circulation; The flow process sewage disposal is undesirable etc.
Summary of the invention
The purpose of this invention is to provide a kind of oil well operation impurity sedimentation treating apparatus, oil well shaft bottom sediment is carried out filtration treatment, practice thrift operating cost, improve filter efficiency.
The technical scheme that the present invention adopted is:
Oil well operation impurity sedimentation treating apparatus includes casing, it is characterized in that: be provided with dividing plate, italic in the casing at a distance from sand plate and sliding sand plate; Dividing plate vertically is arranged in the casing, and the one of which side is a water-supplying chamber; Sliding sand plate is arranged at the middle part of dividing plate opposite side, and its side near dividing plate is higher, and relative opposite side is lower, and sliding sand plate top is an expansion chamber, and the below is a rest chamber; Italic is set up in parallel above sliding sand plate at a distance from the sand plate successively; Italic is provided with filtering holes at a distance from sand plate and sliding sand plate; The dividing plate below is provided with water hole.
Described water-supplying chamber bottom is provided with the clear water delivery port; Described expansion chamber bottom is provided with the sand removal mouth, and top is provided with dirt inlet, and faces the plate face of italic at a distance from the sand plate; Described rest chamber bottom is provided with sewage draining exit.
The aperture of the filtering holes of described italic on the sand plate, the direction that flows into along sump oil reduces successively.
The present invention has the following advantages:
The present invention utilizes the italic that self is provided with at a distance from sand plate and sliding sand plate; Sandstone to oil well in fuel-displaced has carried out effective filtration and deposition; The italic filtering holes intensive filtration effect that the aperture reduces successively on the sand plate; Conscientiously solved the engineering difficulty that brill is swept in sand washing in the operation process, reduced water consumption, thereby reduced production cost.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is carried out detailed explanation.
Described oil well operation impurity sedimentation treating apparatus includes casing 1, dividing plate 2, and italic is slided sand plate 4, clear water delivery port 5 at a distance from sand plate 3; Sand removal mouth 6, dirt inlet 7, access hole 8, sewage draining exit 9, filtering holes 10; Water hole 11, observation port 12, expansion chamber 13, rest chamber 14, water-supplying chamber 15.
Italic all is provided with filtering holes 10 at a distance from sand plate 3 with sliding on the sand plate 4; Dividing plate 2 belows are provided with water hole 11; Water-supplying chamber 15 bottoms are provided with clear water delivery port 5; Expansion chamber 13 bottoms are provided with sand removal mouth 6, and top is provided with dirt inlet 7, and face the plate face of italic at a distance from sand plate 3; Rest chamber 14 bottoms are provided with sewage draining exit.
The aperture of the filtering holes 10 of italic on sand plate 3, the direction that flows into along sump oil reduces successively.
At first, sump oil enters into expansion chamber 13 through dirt inlet 7, filters at a distance from sand plate 3 each plate through italic successively; Flow on the sliding sand plate 4 and refilter; Sandstone class impurity can not be trapped on the sliding sand plate 4, because of sliding sand plate 4 is obliquely installed through italic filtering holes 10 on sand plate 3 and sliding sand plate 4; The sandstone class impurity that is detained can glide along sliding sand plate 4, and discharges from sand removal mouth 6.With sliding on the sand plate 4 filtering holes 10 all is set at a distance from sand plate 3 in italic, has guaranteed effective filtration of sump oil; Italic reduces at a distance from the pore size filter on sand plate 3 each plate from front to back successively, has more strengthened the filter effect of sump oil.
Then, the sump oil after the removal of impurities flows in the rest chamber 14 through the filtering holes 10 on the sliding sand plate 4, carries out water-oil separating after leaving standstill; Water stratification occupies down; On oil reservoir occupied, it is temporary that the water hole 11 that the moisture content layer is provided with through dividing plate 2 bottoms gets into water-supplying chamber 15, discharges through clear water delivery port 5 then.
At last, the dirt that is detained in the rest chamber 14 is discharged through sewage draining exit 9.
In addition, the water outlet of clear water delivery port 5 recycle once more is used for sand-flushing, has reduced the operation water consumption significantly, has controlled operating cost.
Rest chamber 14 is provided with access hole 8, utilizes flangeseal, safeguards and maintenance in order to device; Expansion chamber 13 all is provided with observation port 12 with water-supplying chamber 15 tops, can open the running status of observation device at any time.
