Abstract
The present invention discloses a heavy anti-pollution agent for petroleum drilling. Its adopted raw material is industrial and mineral powder or ore ground and screened to 200 meshes. The density of said industrial and mineral powder or ore powder must be greater than 2.7 g/cm3, water-washing weightlessness rate must be less than 5%, and acid solution rate must be up to above 10%.
Description
The invention belongs to oil drilling weighting agent technical field, what relate generally to is a kind of oil drilling Weighted anti-contaminative agent.
At present, the traditional weighting agent that is used for improving fluid density when oil drilling mainly contains iron ore powder, ground barium sulfate and Wingdale, on complete processing and tooling cost, use traditional raw material processing general all from boulder, at first to screen various rocks below 200 orders after with crusher in crushing, complete processing complexity not only, use equipment is many, investment is big, and can cause severe contamination to surrounding environment in process of production.From preventing on the hydrocarbon contamination, though iron ore powder has certain solubility in acid, the resultant viscosity after it acts on acid is big, not the easy to clean gas channel and the raising rate of oil and gas recovery; And ground barium sulfate does not react with acid; Though the molten son acid of limestone powder because density is low, has limited its use range.From reducing on the cost, because traditional raw material is general and use material ground apart from apart from each other, thereby trucking costs is higher, thereby cost is strengthened.And it is an industrial raw material, serious waste raw-material further development and use.
The present invention is according to the existing deficiency of above-mentioned traditional weighting agent, at present industrial and mining enterprises in producing the commodity process, when bringing material progress to the mankind, brought serious pollution also for our living environment, pile up like a mountain for the slag muck that is seen everywhere, the muddy water permanent current, makes common people soul-stirring.These slag mucks increase considerably the environmental protection treatment expense, make producer's back millstone around one's neck.How just can turn waste into wealth? it promptly is task of the present invention that these slag mucks are used for substituting traditional oil drilling weighting agent, by utilizing slag muck to substitute traditional oil drilling weighting agent, can cut down finished cost, simplified processing process, saving manufactured energy, minimizing are polluted, and improve the rate of oil and gas recovery, enlarge use range, gather materials on the spot, reduce use cost and trucking costs, turn waste into wealth environment purification.
For finishing above-mentioned task, the present invention is achieved by the following technical solutions: the starting material that the present invention adopts are that industrial and mineral powder or ore screen to 200 orders through grinding, and its density requirements is greater than 2.7/cm
3More than, the washing rate of weight loss requires below 5%, and sour molten rate is greater than 10%.
It can be molybdenum ore, mine tailing or chrome ore mine tailing etc. that the said industrial and mineral powder of the present invention is opened.
The present invention is through the density to the molybdenum ore mine tailing sample that provides, and partial properties such as purity and sour molten rate are estimated, and its result is as follows:
One, test method:
1.1 instrument and vessel
A, balance: sensibility reciprocal is 0.01g;
B, density bottle: Li Shi density bottle, scale division value: 0.1cm
3
C, beaker, graduated cylinder etc.
1.2 reagent and material
A, anhydrous kerosene: 2Kg
B, hydrochloric acid: 15% concentration
C, filter paper
2.1 density measurement
A, add anhydrous kerosene between the initial scale (0-1.0ml) in dry, clean Li Shi density bottle, read the kerosene volume reading under the constant temperature, this reading is the V of the initial volume of kerosene
0
B, the about 80g of weighing (standard is to 0.05g) are at the sample (m) of 105 ± 3 ℃ of dry postcooling, add in the Li Shi density bottle, tapping, roll or shake density bottle, as far as possible the air of bringing into is all got rid of, under the same temperature during with survey original coal oil volume, read last kerosene volume reading V
1
Sample rate ρ is calculated as follows:
In the formula: ρ---the density of sample, g/cm
3
The quality of m---sample, g;
V
0---the initial volume reading of kerosene in the density bottle, cm

2.2 sample purity is measured
Here the sample purity of indication is meant the content that can be used as weighting material in the sample.The main weightless method of washing that adopts is measured, concrete grammar is got the sample of the about 100g of weight (being accurate to 0.05g) exactly and is eluriated sedimentation after 30 minutes with a large amount of clear water, suspended substance inclines, eluriate repeatedly, sedimentation several times, up to eluriating water than after clear, dry the solids that weighing settles down, what observation was inclined in the test mainly is the clay thing.The current rate of weight loss:
A: rate of weight loss, %;
W
0: sample is heavy, g;
W
1: washing sample oven dry back is heavy, g.
2.3 sour molten rate is measured
Claim 3g sample (being accurate to 0.01g) to join in the hydrochloric acid of 15% concentration, room temperature (12 ℃) glass rod down stirs acid after molten 30 minutes, and clear water is cleaned, and the oven dry residuum is also weighed.
The molten rate of acid:
In the formula: B---sour molten rate, %;
G
0---sample is heavy, g;
G
1---the molten back of acid residuum is heavy, g.
Two, test-results:
