Abstract
Gas-water well, oil gas water well help the chemical agent composition of quarrying oil, natural gas in a kind of recover petroleum, the natural gas process, this helps oil recovery, gaslift liquid rod (jy) to integrate foaming, fall resistance, washing, divergent function, and under oil-gas field geology conditions such as deep-well, high temperature, high salinity water quality, high oil-water ratio, can improve air-flow effectively and vertically lift the liquid ability, reduce the frictional resistance that gas-liquid two-phase flows, thereby reach the purpose of frscturing.
Description
The present invention is the chemical agent composition that helps quarrying oil, natural gas in a kind of recover petroleum, the natural gas process, belongs to oil, natural gas extraction technical field.
At oil, in the gas-field exploitation process, because layer of oil gas production poor permeability, strata pressure is low, or reason such as oil-gas field development later stage reservoir pressure depletion, make oily, can not lean on the energy of self will follow the liquid in oil gas inflow shaft bottom to enumerate well head in the gas well, so that hydrops is added in the pit shaft, back pressure increases and near region, shaft bottom permeability variation, the recovery ratio that this just has a strong impact on the ordinary production of oil gas well and reduces oil gas, since 1980, the development of Sichuan academy of petroleum office has also been used foam drainaging gas cutting process technology, but medicament is single, foaming power is poor, and be liquid, give transportation, store and use all inconveniences, to the well of packer is arranged down, oil, sleeve pipe is scurried logical well and can't be used, U.S. SEIECT company development the excellent solid blowing agent of cunning (seeing SLICK STICKS manual), the resistance function is fallen though have to bubble, can get rid of hydrops to a certain extent, but it is poor that its shortcoming is a grease resistance, and a little less than the foaming power, the less stylus of proportion falling speed in well is slow, molten faster speed makes the stylus weak point of holding time in well, limited making full use of of active ingredient, amount of consumption of drugs is big as a result, the cost height, per kilogram is up to 13.12 dollars.
The objective of the invention is to avoid above-mentioned shortcoming of the prior art and a kind of oil recovery, gaslift liquid rod (jy) of helping is provided, this is lifted liquid rod collection and bubbles, resistance, divergent function are fallen in one, in deep-well, high temperature, high salinity water quality, do not reduce its function under the geological conditions of high profit proportion, can improve air-flow effectively and vertically lift the liquid ability, reduce the friction that gas-liquid two-phase flows, thereby reach the purpose of volume increase oil and gas production.
The present invention relates to a kind ofly have foaming, fall resistance, dispersion, corrosion inhibitive function recover petroleum, natural gas help oil recovery, gaslift liquid rod, it is characterized in that by the amino acids 40-50% that contracts, sodium lauryl sulfate 10-20%, methenamine 5-10%, sodium chloride 10-20% and polyethylene glycol 15-25% form.Optimization formula of the present invention is by the amino acids 47% that contracts, sodium lauryl sulfate 14%, and methenamine 9%, sodium chloride 14% and polyethylene glycol 16% are formed.Making flow process of the present invention is that the amino acids (70 °-90 ℃ of △)/(stirring) that contracts adds polyethylene glycol (70 °-90 ℃ of △)/(stirrings) adding methenamine, sodium chloride, sodium lauryl sulfate (70 °-90 ℃ of △)/(stirring) and clamp-ons mold cools down → help oil recovery gaslift liquid rod.
Because the oil gas that the present invention adopts above-mentioned reagent combination to form is lifted the liquid rod, has the resistance of falling function, for a frontier has been opened up in oil, gas well draining, foamability is strong, the Luo Shi bubble is a kind of stylus up to 24 centimetres, is convenient to transportation, storage and site operation, and significantly anti-oily effect is arranged, can under 50% oil-water ratio hole condition, use.
Now do to implement for example back according to above-mentioned flow process with optimization formula:
1, the amino acids 47% (70 °-90 ℃ of △)/(stirring) that contracts adds polyethylene glycol 14% (70 °-90 ℃ of △)/(stirring) and adds methenamine 9%, sodium chloride 14%, lauryl alcohol acid sodium 16% (70 °-90 ℃ of △)/(stirring) is squeezed into mold cools down-help oil recovery gaslift liquid rod, should weigh 2.5 kilograms of input high temple, mausoleum, Chuan Nan mining area 28 wells (for a bite oil gas-water well) altogether by 4 of rods, the gained data are: before the caber, 516 liters of day produce oils, 19593 cubic metres of daily gas, 27 liters in daily output water, behind the caber, 1264 liters of day produce oils, 27082 cubic metres of daily gas, 86 liters in daily output water, visible oil, gas, the aquatic products amount all obviously improves behind caber.
That 2, continues to use that above-mentioned optimization formula makes helps oil recovery gaslift liquid rib 8 rods to weigh 5 kilograms altogether to drop into Chuan Nan mining area plum Ba17Jing (for a bite tubing and casing is scurried logical low pressure, low yield gas-water well), the gained data are: before the caber, 7522 cubic metres of daily gas, arrange not water outlet, behind the caber, 13614 cubic metres of daily gas, 6.66 cubic metres in water of daily output, show caber after gas output increase substantially.
