| Currently, the oil-field Sanan development area has already especially got into Gao Han boiling hair stage, the surplus can adopt to keep quantity to year by year lower, adding can adopt to keep quantity difficulty very greatly, surplus oil height dispersion, for efficiently dig Qian to provide basis, is the development of the oil-field adjust service.This research passes to develop a3D earthquake explanation a result research, study course of river sand body at3D space of distribute regulation, guide fine oil to hide a describing;Carry out constructing of Sa, Pu and Gao You Ceng and break1F characteristic further, especially partial small structure appearance and small break the space of layer of characteristic;Study Sa zero sets of keep1F of the thicknesses distribute scale and spirit crest scope and obtain to the breakthroughs that keep1F understanding;Study the well earthquake consociation model method.This research combines well and measures well and development dynamic state data according to the high accuracy3D earthquake data and aim at to influence an oil-field development of small break a layer and kept a layer to carry on a fine explanation, obtained more abundant research result.The oil-field development faces a hard nut to crack varied, substantially is an oil to hide a geology characteristic to know not enough thorough, namely to small the accuracy of estimate breaking a layer to identify and keeping1F is not enough the demand that satisfies an oil-field development.For this, is a point small estimate for breaking a layer to identify and keeping1F, play model just, table resolve the technique apply in small break an identifying of layer to reach agreement to release, identify to settle to be apart from be small for10m to break a layer as follows, set up a set of suitable Ta-ching oil-field and similar earthquake geology under the condition of high accuracy earthquake the data Be small to break the1F explanation technique frame.Owing to the ant tracks method emulation the ant is in the process of looking for food in discover the behavior of path, is a sow in to look for to combine in the sketch excellent turn several choice techniques of path, is carry on the process that induces to generalize to form the best path to numerous paths.Therefore this research tracks an ant method is pass in the earthquake data to sow Sa in the body a great deal of electronics ant and carries on tracking towards breaking the1F excrescent value and release to break the1F information vegetable in the meantime and use information vegetable as the communication lies quality to deliver an information and call other ant concentrations of certain scope comes over, the common cooperation carries on break a layer of identify, track, a finally born low Zao voice, have clear break1F of the data body of track.The curvature body attribute can indicate a position that the geologic strata occurrence form changes, for break a layer is an indirect reflection, but5meter as follows of small break a layer, hang to break to be apart from upward very small and usually extend distance in the flat surface very short.But the ant track to all be good to respond to to breaking of different preface layers(crack), and the ability strict implementation breaks the position of layer, but from break the flat surface continuous sex effect that the1F tracks don’t have curvature attribute reflection of better.The effect that blends from the body sees, the curvature body tracks of break layer and ant body to track of break a layer to break1F in the big lord stem, tops can fit together very good, difference only lie in small break the detail that the1F tracks up.So pass the fusion of ant body and curvature body attribute, the comprehensive usage ant body tracks, the curvature body attribute,3D earthquake data with have already known the well data drills to meet of break some information as a verification, carry out the fine breaking1F to small less than5meters to depict.This text passes at make selection of develop to keep the1F fine geology research inside the district, is lengthways very high a resolution towards keeping a layer because of measuring well data, can provide oil to hide to hang to variety of detailed information, but in the horizontal upward estimate ability but very limited;With measure the well data compares, the earthquake data has better horizontal continuous, can even reflect the horizontal variety of geologic strata and have better horizontal estimate ability, but the earthquake flaps to directly reflect rock variety, its hanging far and far can not satisfy the oil in present stage and hide a development need as well to the resolution, even if the process wave resistance is anti-to play.For satisfying Gao Han Shui to expect the demand that the oil hides a fine description behind, request to use a well earthquake unite the technique develop to keep1F fine research.With artesian well, measure well data for the lord make reference to earthquake data in order to study a method, went deep in to delicately study small break to be apart from to break a layer, crack, slight structure etc..The system analyzed zero to spread small break point of distribute a characteristic and small break the1F formation principle, tally up a set of small method for breaking and being apart from and breaking and ordering a fine combination, the push breaks a layer again the knowing turn the progress of direction development to the fine, with more is fine structure result with keep1F understanding and effectively guide Sa south development the area expect the surplus oil of the stage and distribute after mining, illegitimate profit well dynamic state analysis, well design project etc. work. |
