Research On The Control System Of Oil Extraction Joint Station Based On PLC

Oilfield development late, a large number of oil and gas has been taken out, multi-well, multi-layer high water content, the remaining oil was highly dispersed on the whole, local as well as the pattern of relative enrichment site, the equivalent of "the water to find oil." Especially in high abundance reservoir heterogeneity strong point bar sand body distribution of remaining oil is very complex. How to effectively determine the point bar sand body distribution of remaining oil field late high water cut point bar sands development is a challenge in terms of the development process of adjustment facing increasing reserves for the production of these fields in the future is important.In this thesis, the use of vertical logs on the establishment of a river abandoned logging phase mode, the application "sand top relative depth Law" Fine identified plane abandoned channel, to achieve a single sand body identification; and the internal structure of theory building and outcrop information as a guide, to study the meandering river point bar type identification, according to the A / S ratio of size, to determine the distribution of point bar sand body styles, namely: geomorphic conditions in equivalent circumstances, with the A / S ratio reduction small, river diversions migration and increasing frequency, point by point bar sand bodies to develop scaly; response characteristics of a side-laminated logs to determine the quantitative relationship between a single point of the dam and activities span the width of the river between the dam and the point inside relationship with the river-side lamination angle width to depth ratio; on the analysis of the internal use of point bar sand body condition and remaining oil distribution on the proposed dam on the point of remaining oil sands are mainly distributed in the vertical point bar sand body of high water content parts of the plane by a combination of factors affecting a particular network and the development of the system, such as wells, with a high degree of complexity; eventually developed a single well individualized treatment programs, tapping the potential of technology supporting the formation of different genetic point bar sand bodies.Project research for guiding the late high water cut point bar sand body distribution of the remaining research and supporting potential, has important significance.
