The Sequence Stratigraphy And Sedimentary Facies Of Pu Tao Hua Reservoir Of Gu Long South Area

Paper studies in high-resolution sequence principle of stratigraphy to fully digested and absorbed to provide guidance predecessors, to finish drilling wells, logs, integrate and comprehensive research and technology of the subject line. To drill, the information of mainly logs, the seismic sections show the establishment of vocational and southern parts of his high resolution stratigraphic sequence space, on the basis for the high resolution in the stratigraphic sequence, the readers reservoir, the structure of the characteristic features of the study predicts stripes , the results were better for his southern parts of a prospecting progress and development provides geological.The southern areas are the flowers in the delta leading to the west and north of the source object, the source of sand body from the north to south, the width of the thickness of sand body is reduced, a "narrow, thin, his southern regions." characteristic of grapes flowers zoned as a medium-term the back, the three short back and eight ultra short, the division to six levels of sequence. Grapes layer of oil the flowers, into the water, sediment is backed up, the type Deposition layer for a deposition to the ongoing review of the high ground and taizi with a thick and thin the northwest region the south-east corner stratigraphic research, the most part of it. In high-resolution sequence of analysis control, the heart of his southern regions of the grapes of a flower layer of oil the typical pattern of flowers, the grapes are the major development in the water tap layer of oil sand, the estuary, the dam burst under the door mat, with a clear out the light of the readers the plane at the cloth, on this basis, along with his south region oil layer profits are distributed from flowers and growing characteristics of the law that six favourable together with stripes. The study established his southern district high resolution stratigraphic sequence space plane. the ground with the law of evolution, the gathering beneficial stripes region, the results of research areas further exploration provide a foundation, an important theoretical and practical significance.
