Description
Technical field
The invention belongs to technical field of petroleum extraction, be specifically related to a kind of solution component that can be used for the heat from hydrogenation chemistry volume increase that improves low-permeability carbonate reservoir oil well productivity.
Background technology
Carbonatite is very important reservoir rock, accounts for 20% of world's sedimentogeneous rock total area, and its oil and gas reserves accounts for 50% of world's total reserves.China had successively obtained the great discovery of carbonatite oil gas resource in the area such as Tarim Basin, Sichuan in recent years.Carbonate rock hydrocarbon reservoir has the features such as dark, reservoir properties is poor, nonuniformity is strong, per-well production is low of burying, and acid-fracture technology is the common method of carbonate reservoir transformation.
Acid fracturing refers in the acidification technique that is enough under the pressure that presses off formation crack, stratum or open stratum primary fracture, stratum be clamp-oned acid solution.Acidizing fracturing process is mainly divided into prepad acid fracturing fracturing technology and fracturing liquid and acid solution and replaces injection technology.The former is by injecting the non-reacted preposition fracturing liquid of high viscosity to stratum, pressing off on the basis in formation crack, stratum, realizes pressure break by injecting acid solution.The latter alternately injects by high viscosity fracturing fluid and acid solution a kind of method that realizes acid fracturing, and its main advantage is that sphere of action is large, acid-etched fracture penetration range is long, acid liquid loss is low etc.Transform by acid fracturing, can improve the seepage flow condition of immediate vicinity of wellbore, improve single well yield.The zone thickness of acid fracturing one-stop operation processing is unsuitable blocked up, and formation temperature is unsuitable too high.In addition, need to employ large-scale implement, construction is complicated, cost costliness, and also some throw out easily causes secondary pollution.
Summary of the invention
The object of this invention is to provide a kind of solution component of the heat from hydrogenation chemistry volume increase that improves low-permeability carbonate reservoir oil well productivity, specifically for rate of permeation 10 × 10
-3～50 × 10
-3μ m
2hyposmosis carbonate rock stratum.This solution component, by improving carbonate rock stratum rate of permeation, improves single well productivity.
The heat from hydrogenation chemistry method for increasing yield of carbonate reservoir oil well is to utilize the physics chemical action of the chemical reaction being injected between working solution in well and between working fluid and rock stratum to adjacent to oil well area, thereby the rate of permeation of improving immediate vicinity of wellbore, improves single well productivity.Compared with acidizing fracturing process, heat from hydrogenation chemistry method technique is simple, possesses that advantage, volume increase time length that thermal recovery, pressure break and acidifying combine are long, recovery ratio is higher, can application in Carbonate Reservoir exploitation.
The present invention is achieved in that
First, prepare three kinds of working solutions (No. 1 solution, No. 2 solution, No. 3 solution), require No. 1 solution and No. 2 liquor capacity sums to be less than the volume of hyposmosis oil well reaction zone.The space (see figure 1) of reaction zone in referring to from artificial bottom of a well to perforation district upper surface sleeve pipe farthest, is calculated and is guaranteed that first two solution can fully react by chemical reaction.
