Problems solved by technology

The national industry standard stipulates that the acid corrosion resistance of the ceramsite proppant must be less than or equal to 5%, and the ceramsite proppant must be required to have a high acid corrosion resistance during use, because: the crude oil mined underground contains Acidic minerals, ceramsite proppant soaked in acidic environment, when oil and gas continue to pass through, the proppant will be pickled to dissolve the proppant into powder, so that it will not only fail to support the proppant, but also block the oil flow. shortening the life of the well
At present, the ceramsite proppant used has the following disadvantages during use: uneven particle size, poor compressive performance, and easy to break; but the main disadvantage is: low acid corrosion resistance, which can easily lead to local blockage, oil and gas Poor circulation, unable to support fracturing fractures more effectively, reducing permeability in fractures, low oil production rate, and waste of resources

Abstract

The invention provides a high-strength ceramsite proppant and a process for preparation, wherein the agent comprises (by weight percentage) Al2O3 74-80%, SiO2 5.5-10.5%, TiO2 2.5-3.5%, Fe2O3 4-9%, other adjuvant 0-3%, the agent also contains SiO2, TiO2, Fe2O3, MnO2, K2O, Na2O, CaO, MgO. The preparation consists of mixing the components into mixed powder, rolling into balls through aerial fog, and finally obtaining the end product through high-sintering.

Description

technical field [0001] The invention relates to a high-strength ceramsite proppant, and also relates to a preparation method of the ceramsite proppant. Background technique [0002] Usually, proppants are used in oil and natural gas deep well mining and ultra-deep well fracturing processes to provide high-permeability channels for oil and gas flow, maintain high conductivity, and increase oil and gas production. In traditional oil extraction, natural sand is generally used as proppant, and there are also proppants made of other materials such as clay, lanthanide metal oxides and manganese dioxide. The national industry standard stipulates that the acid corrosion resistance of the ceramsite proppant must be less than or equal to 5%, and the ceramsite proppant must be required to have a high acid corrosion resistance during use, because: the crude oil mined underground contains Acidic minerals, ceramsite proppant soaked in acidic environment, when oil and gas continue to pass...
