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

This article, guided by the theory of modern sedimentology, make full use of drilling data, seismic data and well logging data, small layers in detail to the reservoir classification and correlation, and the sedimentary facies and sedimentary microfacies, reservoir space distribution regularity of sand body, reservoir characteristics and heterogeneity of in-depth study.Through research, marked by the lake flooding surfaces such as layer, straighten out the small interlayer formation sedimentary sequence of the high-resolution sequence stratigraphy theory, use well, combined with 3 d seismic phase guidance about control, a south of oil group small 8 and 11 small layer at the bottom of the lake, the relative stability of the mudstone layer of the generic function deposit for isochronous interface, according to the oil group of inner sequence stratigraphic characteristics, set up small standard profile layer classification and correlation of sequence stratigraphy, and through the establishment of backbone profile and contrast, completed the work area 194 Wells contrast and small layers, divided into system layer improves the contrast between sand body well tracking precision, on the research methods and techniques in the forefront of development geology research techniques.Through the rock facies, bedding structure and particle size analysis to determine the area south a mainly braided delta depositional system.South section is given priority to with low porosity low permeability reservoir, lithologic mainly medium sand, fine sandstone, conglomerate and glutenite is less.Pore types are mainly primary intergranular pore, dissolution, intergranular pore, dissolution intragranular pore(feldspar dissolution pores and debris dissolution pore) mold crack corrosion pore and solution pore.Through to the relatively high oil production Wells reservoir sedimentary microfacies analysis, to determine the main sedimentary microfacies in the reservoir region in the development of underwater braided distributary channel sand body.
