Abstract
Naftno-plinsko polje Ladislavci nalazi se u istočnoj Slavoniji na području sela Ladislavci koje je udaljeno desetak kilometara od Donjeg Miholjca. Na polju Ladislavci danas postoji 21 bušotina. Ležište nafte je u miocenskim naslagama vukovarske formacije, a plinsko u osječkim pješčenjacima (serija B). Ležište nafte podijeljeno je u tri ležišna sloja (El, F1a i F1b) i radi se kombiniranoj zamci strukturno-stratigrafskog tipa. Ležišne stijene su vapnenačke breče, klastični vapnenci i... More brečo-konglomerati. Nakon opisa osnovnih svojstava umjetnih neuronskih mreža i povijesti njihovog razvoja, prikazane su još i elektrokarotažne metode čiji su rezultati korišteni za interpretaciju ležišnih stijena te kao ulazni podatci za uvježbavanje neuronskih mreža. Neuronske mreže su uvježbavane na podatcima iz bušotina (A i B) i to u intervalu od EK-markera Rs7 do dna bušotine. Na tim mjestima kao ulazni podatci izdvojene su vrijednosti spontanog potencijala (SP) i električne otpornosti (R16 i R64). Iz takvih ulaza predviđan je litološki sastav uz pomoć višeslojne perceptronske mreže (skr. VPM). Less
Abstract (english)
The Ladislavci Oilfield is located in eastern Slavonia, in the Ladislavci village, about ten kilometers from Donji Miholjac. There are 21 boreholes in the Ladislavci Oilfield today. The oil reservoir is in the Miocene deposits of Vukovar formation and gas reservoir is in Osijek sandstones (series B). The oil reservoir is divided into three sections (El, F1a and F1b) and it is a combined structural-stratigraphic trap. The reservoir rocks are limestone breccia’s, clastic limestone... More and breccia conglomerates. After the description of basic properties of artificial neural networks, well logs have been presented, whose results are used for the interpretation of the bedrock and as input data for the training of neural networks. Neuronal networks are trained on the data from wells (A and B) from the interval of the EK marker Rs7 to the bottom of the well. The analysis input data where log data (curves SP, R16 and R64) and from such data the lithological composition is foreseen with the help of multilayer perceptron network (MLP). Less
