Description
Technical field
The present invention relates to a kind of drilling fluid skimmer tank, sneak into the skim of the oil of drilling fluid for the oil and gas well drilling process, belong to the design and manufacturing technology field of drilling equipment.
Background technology
In the drilling process of implementing oil or natural gas, in order to make in drilling fluid to there is lubrication preferably, usually can use oil base drilling fluid, when drilling well proceeds to underground some oil-bearing layer, underground oil also can be along with drilling fluid together is brought to ground, and sneak in drilling fluid, if these oil of sneaking in drilling fluid are got rid of not in time, will be again along with drilling fluid is injected underground by slush pump, then also have more underground crude oil and enter drilling fluid, after reaching certain quantity, will destroy the performance of drilling fluid, finally may cause drilling fluid can not well complete rheological characteristic and the shear effect of drilling process needs, and drilling well is caused to serious harm.In order to address this problem, the way adopted is at present mainly processed destroyed drilling fluid, then add the material lacked, the mechanical oil extraction of the employing also had and remove deimpurity equipment, as: the patent of CN200710118618.8 discloses a kind of drilling fluid treatment system, comprise: except silt particle section, degasification section and composite section, the drilling fluid returned out from well head successively after removing silt particle section and degasification section and removing respectively landwaste and natural gas, compositely enters ash material and aqueous chemical medicament at composite; The patent of CN201120476036.9 disclose a kind of sledge charge of oil water on the spot separator water return and mix device, be applied to the oil field well water filling.The employing also had oil, gas, water, solid four-phase separator; The shortcoming of prior art is:
1. the separation that technology as disclosed as patent No. CN200710118618.8 can only be gentle for the solid to drilling fluid, can not realize being blended in the separation of the oil in drilling fluid.
2. the patented technology that the patent No. is CN201120476036.9 is to be applied to the oil gas field underground water-injection, can not be for the separation of drilling fluid.
3. the shortcoming of other the drilling fluid of the mechanical type for oil/gas drilling scene separator is: because existing separator has together the filter plate with mesh basically in the link of separating, and the dividing plate of one water-oil separating, because the size of mesh is fixed, mesh too conference passes through landwaste less in drilling fluid together with oil, therefore can cause the crude oil be blended in drilling fluid to separate not thorough, separative efficiency is low, and flow through in the crude oil of dividing plate and also have a certain amount of drilling fluid, therefore cause crude oil to collect inconvenience.
Summary of the invention
The object of the invention is to can not effectively separate for prior art the problem of the crude oil in drilling fluid, a kind of drilling fluid skimmer tank is provided, the present invention adopts the mode of precipitate and separate, and the crude oil of sneaking in drilling fluid is separated automatically.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of drilling fluid skimmer tank is characterized in that: comprise tank body, in described tank body, along flow direction, be disposed with oil-feed storehouse, separation bin and discharge storehouse; The oil-feed storehouse is communicated with the oil-in arranged on tank body, and the oil-feed storehouse is communicated with separation bin, and separation bin is communicated with the discharge storehouse, discharges storehouse and is communicated with the discharge pipe arranged on tank body.

Operation principle of the present invention and implementation process:
The drilling fluid returned out from well head to the oil-feed storehouse, after the filtration of filter plate 5, enters separator through oil pipeline that (oil-in 3) connects in the ninth of the ten Heavenly Stems.And the solid phase residue precipitated in the oil-feed storehouse is cleared up away from ash gate 2 when off working state, from filter 5 filters drilling fluid enter separation bin, in separation bin, slowly, stably flow, larger former oil particles separates with drilling fluid.At first the crude oil particle aggregation separated, and float up to the drilling fluid surface, cross and separate dress device 6, enter and discharge storehouse; Separator 6 is comprised of the stainless steel wave card 16 that contains skewed slot of solid matter, and further steady flow makes former oil particles produce speed upwards simultaneously, promotes the crude oil particulate further to separate with drilling fluid; Oil baffle 8 can be by some little, the former oil particles gear floating to certain altitude carries out secondary settlement in separation bin, make it to assemble, float and separated; Oil trap 7 can be collected the crude oil of having separated and discharge by oil exit pipe 17 when operating fluid level; The drilling fluid of oil removing enters the discharge storehouse from the liquid communication passage of oil baffle 8 bottoms; If discharge the circulation of drilling fluid jar liquid surface of the relative drilling team of liquid level in storehouse, enough differences in height are arranged, drilling fluid can flow directly into by discharge pipe 11 well-drilling liquid circulation pot of drilling team; If liquid level is poor to be not enough to form effectively and to flow, can start cantilevered submerged pump 9 and drilling fluid be pumped into to the well-drilling liquid circulation pot of drilling team, now need liquid level float-controlled valve 10 control the startup of cantilevered submerged pumps 9 and stop, keeping liquid level stabilizing.
As shown in Figure 4, between corrugated plating 16, with supporting section, connect, making its spacing is 6mm, the long 1120mm of corrugated plating, wide 496mm, spacing 50mm between every group of separating mechanism.
This separator adopts the Corrugated Plates Coalescing Oil-water Separation Technology, is Gravity Separation and coarse separation to be incorporated into to the new oil water separation structure of one, has energy consumption low, and separative efficiency is high, the characteristics such as equipment is simple, compact conformation.
Separation principle: the separative efficiency of oil droplet is only relevant with oil droplet buoyance lift area with physical property, oil droplet size, the treating capacity of profit after deliberation, in the situation that treating capacity is certain, the main method that improves the oil droplet separative efficiency has thus: increase the alternate density contrast of profit two; Increase the diameter of buoyance lift oil droplet; Increase the buoyance lift area of oil droplet; Reduce aqueous viscosity.
Improve the oil droplet separative efficiency by shortening oil droplet buoyance lift height, the profit mixed phase, in the interior flow process of separator 6, because flow section constantly changes, thereby increases the probability of oil droplet collision coalescence simultaneously, the continuous coalescent change in motion process of little oil droplet is large, by absorption, the effect such as coalescent, form oil film at the lower surface of corrugated plating, become and move along the plate face, come off, water sedimentation under Action of Gravity Field, the upper surface of arrival lower floor corrugated plating, finally realized water-oil separating faster.
The present embodiment and above-mentioned enforcement are basic identical, and the main distinction is as illustrated in Figures 5 and 6, and described each corrugated plating and horizontal direction are 45° angle.
