The Distribution Of The Sand Of Putaohua Oil Bering Layer In Taidong Area And The Control Action To Accumulation

The geographical location of Taidong region is the depression of the middle part ofSongliao Basin, belonging to the two negative to the constructor. The west of it isChangyuan and the east of it is Chaoyanggou.Putaohua reservoir is important in the studyarea a reservoir. So far, the impact of Putaohua reservoir accumulation of factors of thestudy is still not very thorough. This thesis, the use of sequence stratigraphy, reservoirsedimentology and other academic disciplines, and take the fine analysis of the stratigraphicframework of the study area, the microfacies types of traps, as well as oil and waterdistribution, and summed up the sand distribution characteristics of the region and itscontrol of the accumulation, and thus predict favorable target area, playing a guiding role tothe study of the Sanzhao depression forming rules and prediction of favorable oil and gasreservoir.High-resolution sequence stratigraphy in the theory and quantitative description of thereservoir on the basis of the theoretical study, by analyzing the seismic data, log data,geological data and analysis of log data and with the use of computers, we make the studyof the sequence stratigraphy and sandstone reservoir distribution and control in the target’soil bering layer. First, take advantage of results of previous studies, summarized a variety ofstratigraphic division and correlation methods for the study area to determine theirgeological characteristics, classification and correlation methods. Next, horizontal directionin the study area we draw three main sections, in the longitudinal direction of the draw fourmain sections, to understand the features and overall sedimentary features of Putaohua oilbering layer in Taidong area, in order to make the region’s high-resolution sequencestratigraphic division and correlation of better. Because the number of wells in the studyarea is big and layers are thin, To conduct the study area fine uniform contrast, we need tocompare the overall implementation of the technology. This time uses the establishedisochronous sequence stratigraphic framework of this method, In the time of the sequencestratigraphic framework, depositional system analyzes the patterns and controlling factorsSpread, research produced by a variety of reasons the reservoir sand body characteristics,the purpose is to determine the trap distribution characteristics of the study area and itscontrolling factors. The study area is mainly of a typical single51traps were fine anatomy,summed up the five kinds of Pacific East oil and gas accumulation model, and that thecontrolling factors of oil and gas accumulation, the focus of the sand on the oil and gas accumulation and distribution of control action, in order to predicte the area provedbeneficial and the favorable blank area surrounding the study area.
