Description
Technical field
The present invention relates to drilling plugging agent, particularly a kind of high strength consolidation type plugging agent.
Background technology
The plugging agent with some strength that existing a kind of petroleum drilling uses is quick talking cement, its formula is: oil well cement 100 parts, water 40-50 part, setting accelerator 5-30 part, its leak-stopping technique being petroleum drilling has played effect, but it also exists following shortcoming or deficiency simultaneously: 1. thickening time, setting time and pumpable time are difficult to control, and grout very easily occurs and runs off fast or fast setting problem, and construction safety is difficult to ensure; 2. cement slurry density is high, and easily pressure leaks stratum, and viscous flow ability is bad; 3. viscosity is low, not easily in leakage channel remain in a standstill, solidify after easily come from water, shut-off capacity is poor; 4. setting time, set strength are uncontrollable; 5. after leak stopping, the stopper staying shaft bottom is stone, and the brill plug time is long, and easily make new advances well, or occurs again new leakage after having bored plug, and easily generation repeats leak stopping phenomenon, causes cost up.
Summary of the invention
The object of this invention is to provide a kind of high strength consolidation type plugging agent, adopt the formulated in combination with organism, inorganics and the high molecular polymer that granularity is little, intensity is high, after leak stopping, crushing resistance is high, effectively overcome or avoid the shortcoming that exists in above-mentioned prior art or deficiency, effectively improve plugging effect, shorten drilling period, improve drill speed.
High strength consolidation type plugging agent of the present invention, its composition and content, content is weight part: calcium carbonate 20-40; Silicon-dioxide 5-10; Calcium chloride 1-4; Polyanionic Cellulose 0.1-0.4; Drilling fluid xanthan gum 0.1-0.2; Aluminum oxide 5-10; Magnesium oxide 3-8; Oil well cement 10-16.
Compound method: above-mentioned substance, by its component and content, under normal temperature and pressure, adds successively in kneader with conventional formulation method, mixing and stirring, treats that it dry, pulverize into the particulate preparation of 0.05mm-1mm.
The present invention's tool compared with existing plugging agent has the following advantages or beneficial effect:
1, leakage-stop liquid has the character of consolidation after entering leakage channel, and intensity is high;
2, intensity is high, and expansion character is good, and volume does not reduce.
3, shut-off capacity is strong, can repair low pressure ravelly ground, improves the bearing resistance of absorption well section.
4, outstanding excessive ability is strong, and good fluidity, pumpability is good, can enter leakage channel deep.
5, setting time, set strength is adjustable, can form high strength lost circulation plug in leakage channel.
6, the lost circulation plug formed in annular space, moderate strength, drillability is good, not easily gets out new well, shortens and sweeps the plug time.
7, leak stopping slurry easily remains in a standstill in leakage channel deep, and multiple leakage not easily occurs the high strength leak stopping stopper formed in leakage channel after boring plug, and leak stopping success ratio is high.
8, little to environmental influence, nontoxic, pollution-free, construction safety is quick.
