Description
Technical field
The utility model relates to technical field of petroleum extraction, especially relates to water plugging and profile controlling construction parameter online monitoring system.
Background technology
Oil field development is to the middle and later periods, and supplementing stratum energy by water filling is the major measure that China's major part oil field adopts.Because oil reservoir also exists non-homogeneity, there will be water " advancing by leaps and bounds " and " channelling " phenomenon in oil reservoir, seriously affect the development effectiveness in oil field.In order to improve the ultimate recovery of flood effectiveness and oil field, need to take water plugging and profiling technology measure timely.
For water injection well, due to the non-homogeneity on stratum, the water absorption of every one deck on stratum is all unbalanced, and the water absorption of every part of every one deck is all different, and this is reflected on intake profile.The inhomogeneities of stratum water suction, in order to improve the sweep efficiency injecting water, needing the high permeability zone that shutoff water absorbing capacity is strong, being called profile control.For oil well, due to the non-homogeneity on stratum, the different piece of every one deck and every one deck, oil production and moisture content are all not necessarily identical, and its production profile is uneven.Shutoff high yield water layer, improves production profile, is called water blockoff.Water blockoff can improve the sweep efficiency injecting water, and the success rate of water blockoff often depends on the success rate of water detection.Except directly measuring except production profile, the methods such as temperature logging can also be utilized to determine water exit.
Utilize downhole tool high water accepting layer or high yield water layer to be sealed, be called machinery card envelope.Machinery card envelope sphere of action is only limited to pit shaft scope, but simple owing to constructing, and cost is lower, often becomes top-priority shutoff method.
Inject chemical agent to underground, block high permeability zone or high yield water layer by chemical agent or its product, be called chemical water shutoff.
Sewage from oil-well is different according to source, can be divided into and inject water, Di Shui, Bian Shui.Different water outlet type processing approach is different, adopt blocking agent also different.Different from lg (t) relation curve for Di Shui and Bian Shui, lg (WOR '), WOR is the water-oil factor of the production fluid of oil well, and t is the time.Make to judge there is certain difficulty in this way, lg (WOR ') and lg (t) relation curve can be adopted to judge.For end water, the slope of curve is negative value; For edge-wa-ter reservoir, the slope of curve be on the occasion of.
Play dividing plate to need to carry out intensive perforation in bottom, this can damage the intensity of sleeve pipe, and therefore the scope of application is restricted.Except playing dividing plate, if the approach of liter waterborne for the end is regarded as exhalant canal, the water base blocking agent injected to stratum preferentially can enter water channel, then conventionally can carry out bottom water plugging.End water enters leaching in cone shape, calculates plug agent amount by the size according to this cone.Also can there is limit Shuitu and enter problem in the oil reservoir of edge water drive, therefore also want shutoff limit water, reduces oil well and produce water, make full use of Edge water energy, improves the sweep efficiency of limit water to improve oil recovery factor.Want shutoff limit water, first should study know limit water enter to soak direction, take various close measure by the direction that enters to soak at limit water, limit water advanced to oil reservoir direction equably, thus improves sweep efficiency and displacement efficiency.
As can be seen from profile control effect for many years, profile control has suitable potentiality.But profile control has again certain limit.The first, the increase that water blockoff round and plug agent amount can not be unlimited.Facts have proved, along with the increase of number of profile control, profile control effect can be worse and worse.Meanwhile, plug agent amount increases, and water blockoff cost is also in raising.The second, profile control can only adjust sweep efficiency, can not improve displacement efficiency.The development trend of profile control also embodies how to overcome above-mentioned two limits and the effort made.The first, by developing some industrial wastes as blocking agent as oily sludge etc. in the lime mud of the black liquor of pulp and paper industry, causticizing process basic industry, field produces reduces the cost of blocking agent.The second, overcome the limit in its mechanism by combination of plugging and displacing, i.e. the technology that combines of secondary oil recovery and tertiary oil recovery.
Water plugging and profile controlling measure has become at present and has improved one of waterflood efficiency, the important technology realizing oilfield stable production.Measure site operation parameter monitoring main contents are the change of injection pressure and discharge capacity.The mode of patrolling and examining mainly through manual site is at present monitored, and due to water plugging and profile controlling measure long construction period, measure whole process supervision difficulty is comparatively large, cannot ensure that site operation parameter strictly performs by schematic design, guarantee measure effect.
