The Fine Geology Study On The Oilfield Of Bijialing

Geographical location of Bijialing oil field is located in Liaoning provincePanshan county and near the entrance of Daling river. It consists of shallow sea, beachand continental beach. Regional structure is located on the western depression ofLiaohe shallow sea and salient pitching area of Huludao. It is the earliest developingoil and gas exploration and obtaining commercial hydrocarbon flow area. Lingnanslope zone lies between block structure zone of Bijialing and Hainan sub-sag, and it isone of low exploration areas of Bijialing oil field.With the development of20years, Bijialing oil field mainly has entered thedevelopment stage of high water cut, high recovery percent and low speed. We willhave new high quality reserves into exploration in order to keep stable production andincrease production, therefore we need registration study to structural belt of Bijialing.Main contents are sequence division and comparison, fine structure interpretation,sedimentary facies study, research on reservoir characteristics, reservoir inversion andprediction. The study is developed in the low exploration area of Bijialing oil field,and the whole research process adopted sequence stratigraphy analysis technology,fine structure interpretation technology, multi-attribute analysis and sparse pulse waveimpedance inversion technology. With the help of newly seismic data which havehigh quality and advantage, we can re-recognize the structure and reservoir. Byverifying the dynamic data of the exploration well, oil production test and productiontest, analysising reservoir-forming mechanism and distribution of oil-gas-water,optimizing favorable target area, we will open the new chapter of low exploration areaof Bijialing oil field.
