Prediction Of Mesozoic Reservoirs In The South Of Xingma Buried Hill In Western Depression Of Liaohe Depression

Thrive in liaohe depression in the western sag of southern Taiwan a horse circle buried hill north tectonic belt,has the very favorable hydrocarbon accumulation conditions.The 2006 oil bearing area of 3.46 km2,crude oil geological reserves of 2094.8 x 104 t.The reservoir is known in the world of the thick oil reservoir,the ground condition of the complex geological structure and higher risk,through to the xing ma buried hill belt in southern of the Mesozoic reservoir prediction,can further identify the study area reservoir geology and its characteristics in the development process,using inversion technique to predict reservoir,to improve the further understanding of the reservoir in the study area,and the similar reservoir development is of great realistic significance.The purpose of this paper is to use technology,such as logging,coring,logging data from rock physics study,this paper carried out stratigraphic lithology recognition,delimit and correlation in this area,thus new understanding on the regional geological background;And by using 3d seismic technology,interpretation system,as well as the Landmark workstation TDQ technology into a figure in the study area structure to meet at the same time and make a explanation;Combined with four core physical property analysis and reservoir evaluation of the Mesozoic reservoir in the studied area is evaluated;And by multiwell constraint 3 d sparse pulse inversion technique and JASON software for reservoir inversion analysis,on the one hand,through the three dimensional wave impedance inversion of seismic data to predict the transverse distribution on the blank area reservoir,on the other hand for the drilling of well data statistical analysis,reservoir comparison in order to realize the reservoir prediction.The Mesozoic strata in the study area belongs to the residual deposit,the reservoir is given priority to with volcanic breccia,Mesozoic strata wave impedance for a set of partial high impedance resistance as a whole.In the middle Mesozoic strata in the study area is the part of the development of the inversion effect is better,to the discovery of favorable reservoir is of certain guiding significance.
