[technical field]
The invention belongs to Tracer Test Technology field, particularly relate to a kind of micro-inter-well test method.
[background technology]
Along with oil reservoir development is to meticulous water filling, meticulous steam injection future development, production test also changes to meticulous zonal testing direction gradually, and the means of reservoir monitoring are also more and more important.Inter-well tracer test method describes to have the important means of reservoir heterogeneity and mobility between closing well, can determine that well group is connective, the feature such as high permeability formation, fault properties and remaining oil saturation evaluation between oil-water well by this technology.Inter-well tracer test test is injected in water injection well by tracer, monitors the output situation of tracer around in producing well, if there is tracer to occur in producing well, then proves that water injection well is communicated with producing well, and be the main direction of propulsion injecting water.Utilize the break through of tracer, can determine that each well injects the tempo of penetration of fluid, the number of connectivity layer is relevant to the peak value of tracer output, by software the Fitting Calculation, can the connecting degree of quantitative description water injection well and producing well and reservoir in the plane with the anisotropic in longitudinal direction.The tracer selected can follow the trail of injection fluid effectively, monitoring tracer in well and oil reservoir in dynamic, enroll data exactly, obtained a result by computational analysis, thus reach the object of inter-well test.
Interwell tracer comprises chemical tracer, radioactive tracer, stable isotope tracer, Uranium determination agent.1, chemical tracer mainly comprises: the 1) inorganic salts of Yi Rong: as SCN-, CL-, Br-, I-, NO3-etc., and this kind of tracer is few in surface of stratum absorption, and consumption is little, and the photometer measuring method that is easily split detects.2) fluorescent dye class: as anionic dyes such as famille rose, alizarin red agents, but this kind of dyestuff is large in surface of stratum adsorbance, and some compositions in stratum also can interference analysis, so the time of staying just can not use more than 5 days in the earth formation.3) halogenated hydrocarbons and small molecule alcohol: as fluoro trichloromethane, trichloro-ethylene, dibromopropane etc., they are few in surface of stratum adsorbance, and easily for gas chromatography detects, but impact is had on the aft-loaded airfoil of crude oil.In recent years, along with polymer flooding, Weak Gels drive the expansion of range of application, stratum water quality changed, and brought many difficulties to the detection of chemical tracer and result, and even part tracer can't detect, and does not reach expected effect.2, radioactive tracer mainly contains tritium for compound, as HTO, hydrogen tritide, tritiate heptane etc., although this kind of tracer has few, the easy to detect and detection resolution advantages of higher of consumption, but because they have radioactivity, unfavorable to personnel, Environmental security, application is very restricted.3, stable isotope tracer has without pyrolytic conversion, "dead" harm, consumption is few, execute-in-place is convenient, certainty of measurement high, but the variety protection of stable isotope tracer is few, still need to be activated by the atomic reactor of indoor after some sampling, its radioactive activity is measured by neutron activation method, indoor detection can only be carried out by International Atomic Energy Agency to operate, its analytical test means are numerous and diverse, somewhat expensive, and application is restricted.4, Uranium determination agent is forth generation inter-well test tracer, compared with first three plants tracer, it is the main development direction of current inter-well test tracer, it have "dead", pollution-free, security and stability is good, consumption is few, low price, cost are lower and analysis precision advantages of higher, receive the favor of field operations personnel.
Trace element inter-well tracer test technology is the result that inter-well tracer test technology further develops, it be utilize do not have in stratum and contained fluid thereof or content is atomic, sedimentary characteristic is comparatively concentrated trace element as tracer, draw subsurface reservoir information by monitoring sampled well.It achieve the transformation from qualitative to quantitative, and effectively can react distribution situation and the characteristics of motion of underground fluid, relevant formation parameter can be obtained simultaneously, thus evaluate reservoir situation quantitatively.The analysis precision of micro substance is high, and general chemical analysis can only reach 10-6 level, and micro substance analysis can reach 10-12 level.But the operating procedure of existing micro-inter-well test method is more loaded down with trivial details, cost is more, manpower and materials cost is high.
