Abstract
The invention discloses a screening method for a sulfur-containing petroleum raw liquid in a sealed filtration apparatus, wherein the problem that no equipment for high-sulfur petroleum screening exists in the prior art is mainly solved with the screening method of the present invention. The screening method comprises that: (1) a sulfur-containing petroleum raw liquid enters a filtration chamber through a raw liquid inlet, is subjected to continuous filtration through more than or equal to two filtration chambers, and then is discharged from a raw liquid outlet; (2) the separation mesh of the filtration chamber is arranged on the side wall, the two adjacent filtration chambers are communicated through the separation mesh, and the residual sand and the residual petroleum raw liquid in the filtration chamber enter a sand receiving filter through a sand reservation chamber on the bottom end of the filtration chamber; and (3) with the filtration effect of the sand receiving filter, the filtered liquid returns to the filtration chamber through the raw liquid inlet, and the solid obtained through the filtering is taken out by replacing the sand receiving filter. According to the present invention, the screening method has advantages of reduction of the sand content in the petroleum, no influence on the suction filtration effect on the petroleum, assurance of operator body health, low cost, and the like.
Description
Technical field
The present invention relates to a kind of method for sieving of oil stoste, what be specifically related to is the method for sieving of sulfur-bearing oil stoste in airtight filtration unit.
Background technology
The Main Function of Petroleum screen tube is exactly sand prevention, and because recover petroleum makes the geology residing for oil well, the grade of steel of the pipe that sand bed difference adopts is different with kind.
In petroleum drilling and mining operation, screen casing is a kind of important equipment, often adopts completion or oil extraction sand prevention in advance.At present, more screen casing is used to be wire wrapped screen.The manufacture method of this screen casing is: around being uniformly distributed in, being wound around the steel wire in certain cross section on sieve bar or on the metal liner of perforate and welding, and reserving certain gap as sieve aperture.Although this manufacture method is used by numerous producer at home, but there are some problems when going into the well in this screen casing, especially when suppressing the curved segment by long horizontal traverse well or horizontal well, inevitably collide with the borehole wall or sleeve pipe, extrude and rub, easily there is sleave phenomenon, cause screen damage or gap distortion, cause total completion time and sand controlling result reduce or lost efficacy.
For this drawback of wire wrapped screen, need a kind of for the husky body in oil is filtered, thus reduce the filter plant of sediment concentration in oil.
In oily stoste, usually sulphur content is greater than 2% and claims high-sulfur oil, 0.5% ~ 2% is sulfur-bearing oil, is less than 0.5% for low sulfur petroleum.Sulphur is the objectionable impurities in oil, easily produces hydrogen sulfide, sulfurous acid or sulfuric acid etc., and time serious, meeting etching apparatus and polluted air, if the hydrogen sulfide Long Term Contact that operator and oil stoste volatilize, can cause great infringement to the healthy of operator.
And in prior art, the equipment for filtering has multiple, but be not applicable to the equipment of high-sulfur oil screening.
Summary of the invention
The object of the invention is to solve in prior art the problem of the equipment not being applicable to the screening of high-sulfur oil, provide a kind of and clear up conveniently, the good and method for sieving that is sulfur-bearing oil stoste in the airtight filtration unit that guarantee operator are healthy of screening effect.
For solving above-mentioned shortcoming, technical scheme of the present invention is as follows:
The method for sieving of sulfur-bearing oil stoste in airtight filtration unit, comprises the following steps:
(1) sulfur-bearing oil stoste enters into filtering chamber by stoste entrance, by discharging from stoste outlet after the continuous filtration of plural filtering chamber;
(2) filter of this filtering chamber is arranged on sidewall, and adjacent Liang Ge filtering chamber is communicated with by filter, remains in husky body in filtering chamber and oil stoste and then reserves chamber by the husky body of filtering chamber bottom and enter into and connect husky strainer;
(3) by connecing the filteration of husky strainer, turn back in filtering chamber by filtering the liquid that obtains by stoste entrance, by the more husky strainer of changing-over and then the solid obtained will be filtered take out.
Reserve chamber by filtering chamber, husky body and connect between husky strainer and form a circulation device, the husky body effectively in removing oil stoste, can also avoid operator to contact with oil stoste simultaneously, and then ensure the personnel safety of operator; Meanwhile, setting of the present invention does not affect the filter effect of oil stoste, and filter effect is good.
Further, described in connect husky strainer by sealing box body, be arranged on the filter sieve in sealing box body, the opening for feed being arranged on sealing box body top and be arranged on sealing box body bottom discharge port composition.
Further, described husky body is reserved chamber and is connect between husky strainer and is provided with valve.
Discharge for the ease of in time husky body being reserved husky body in chamber, described husky body is reserved on chamber and is also provided with visual window.
In order to reach sand-flash effect better, the described husky body top of reserving chamber is communicated with filtering chamber bottom, and the wherein sidewall that this husky body reserves chamber is connected with filter bottom.
The present invention compared with prior art, has the following advantages and beneficial effect:
1, the present invention reserves chamber by filtering chamber, husky body and connects between husky strainer and forms a circulation device, husky body in effective removing oil stoste, operator can also be avoided to contact with oil stoste simultaneously, and then ensure the personnel safety of operator;
2, reserve chamber by husky body in the present invention and connect the mating reaction of husky strainer, when can remain rockier body in oil stoste, in time and easily unnecessary husky body can be discharged, thus not affect the suction filtration effect of oil;
3, the setting of visual window in the present invention, can understand the residual condition that husky body reserves husky body in chamber in time, discharges husky body can be reserved husky body in chamber;
4, structure of the present invention simple, with low cost, directly do not contact with operator, and then effectively can ensure the personnel safety of operator, and it does not affect the suction filtration effect of oil, is applicable to very much applying.
