The Method Of Integrating Seism And Geology To Confirm Fault Throw In The Exploitation Of Oil-field

Regard the method of the gaining fault-throw in internal oil-field exploitation as the respect. Above all from the foreign and internal defining of fault throw, point out the problem of easily appearance. Combine the act apply status of fault throw in internal oil-field exploitation, point out the existing problem in the course of confirming fault-throw .Currently, in the oil-field exploitation, existing the phenomenon of garbling the lack thickness of stratum with vertical fault-throw in well logging identification of strata while meeting fault in drilling well. In most case, consider the lack thickness of stratum which contrast the imperfection geologic strata thickness to the well and the well as the fault-throw. The method which using very popular in oil-field exist shortages, it very much easily lead people into the areas of misplay. especially when the seismic person and geology confirm the fault-throw, It often appear inconsistent instance.According to the act in the oil-field development, point out there existing the lack of the definition of fault-throw in the production. Immediately ,start with the method of obtaining fault-throw by seismic or geology in the oil-field development, point out existing the artificial factor of influence in confirming fault-throw in well logging identification of strata, especially emphasized the important of the high accuracy depth 3D seismic data under the condition which fault-throw and fault surface change in space. In accuracy high accuracy depth 3D seismic data, emphasized to discuss the creating accuracy synthesize, and bring forward the method of quality-control. Further point out building high accuracy velocity-field and obtain the map with the change velocity. On top of discuss the accuracy structure interpretation method, in order to going along structure interpretation and confirming fault-throw. Combine the act seismic data, discussed the apply method and skill in during of seismic interpretation with directional and level well which more and more broad, achieve seize on more data, more accuracy depict fault-throw. So that, it provide credible pledge to gain fault-throw that gain the high accuracy depth 3D seismic data and gain the accuracy structure interpretation.At last, put forward the way of depicting the fault with the X,and Z weight of fault displacement. aiming at the fault which strike slip could be neglected, point out acquiring the fault throw and angle with the body of highly quality 3D-seismic data in depth, By applying the method of combining seism to geology , eliminate the mostly artificial factor feint in well-logging geologic identification of strata, externally depict the fault-throw, describe the shovel fault, facture the finely section of linking well to well, there is important meaning by combining seism to geologywhen investigate the close ability of fault etc. And verify the feasibility and the credibility of the method in the production. and apply more credible assure in investigating the throw of fault in the feature.
