Zusammenfassung: | The invention provides a highly-deviated well space in-place method. The highly-deviated well space in-place method comprises the steps that whether contradiction exists in an oil, gas and water relation or not is judged; according to a stratigraphic correlation relation, a small-layer top face structural map is made, and whether a structural tendency is reasonable or not is judged; well drilling and well logging hole-deviation correction sand body bushing altitude depths are compared, and whether a difference exists or not is judged; a well required to perform space in-place operation is comprehensively determined, and the depth correction value is determined; the corrected depth is applied to making the small-layer top face structural map, and if the structural tendency is reasonable and no contradiction exists in an oil, gas and water interface, correction is completed. According to the highly-deviated well space in-place method, an effective method which can determine the reasonable space position is prov |
