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

Damin tun depression shen 84 an 12 block develop rupture, the geologic is very complex, exploitative oil is developing into high water rate level stage. Though study oil well combine with seismography method, guide with high differentiate stratigraphy, reservoir sedimentology, well logging geology, geology of petroleum and production seismology theory. Describe the sedimentary facies mark, the characteristic of sedimentary, reservoir bed characteristic, and the aeolotropism of reservoir bed base on the Damintun depression shen 84 an 12 block well surveying well drilling and well logging datum. All of above give a lot of support for the future exploratory development.Though reach the core wafer identify datum to study the petrology of the reservoir bed get the result that the third phase of damintun depression shen 84 an 12 blocks the main content are arcose and syrosem arcose. mix of diameter grains of sand in the reservoir bed, roughly of the lithologic character and have moderate quantify of mud, they are the permeable bed characteristic. The particle degree of roundness is subrounded first hypocone. sieve ratio is moderate. physical property of the reservoir change much in the vertical, they have a good tendency from up to down in the reservoir bed. Summary the affect elements of the influencing characteristic, they are sedimentary facies distribute, the grain grade, coefficient of sorting and diagenic metamorphism.Discover that the main contents of the clay mineral is montmorillonite, ledikite, kaolinit and chlorite by means of X-ray and electronic scan observe. The main content of the crag is kaolinit, and the main content of claystone is montmorillonite. The study area compose of the interstitial pore space is complicated, the main consist is pre-existing interparticle channel, intercrystal microchannel and secondary origin emposieu etc. the primary content is pre-existing interparticle, the second is secondary origin emposieu and it is comparatively grow, the other interparticle are not grow. Though study the degree of porosity, permeability, hierarchical factor and distributed of the interbed. We have the conclusion that the aeolotropism in the areas are serious. Elaborate the affection to the oil recovery efficiency and remaining oil. Assemble the physical character, petrography character, pore structure, aeolotropism etc of the reservoir rocks study, finally comprehensive evaluate the four experiments block, and give a guideline for oil exploration activity.
