摘要

川东大池干井构造带嘉二2储层已成为目前油气勘探的重点层位,通过对储层沉积特征、物性、受控因素等的综合研究,发现嘉二2储层以晶间孔、溶孔为主,储层为裂缝―孔隙型。嘉二2储层可划分为4类,该区以 类储层为主, 、 类储层在地层剖面上呈局部分布,形成1~2个高孔层段。储集物性主要受沉积相带及溶蚀和白云岩化作用的控制。通过储层横向预测,发现麦南构造和陡翼断层下盘的磨盘―老湾潜伏构造储层较发育,是大池干井构造带下一步勘探及井位部署的重点区域。

Abstract

Presently the T1j22 stratum have become the important stratum of oil and gas exploration in Dachiganjing structural belt of east Sichuan, through  comprehensive researches of reservoir sedimentary feature、 reservoir physical property、reservoir influential factor and reservoir prediction, we find that the  T1j22 reservoir pore spaces were dominated by crystal-to-crystal pores and corrosion pores, and the reservoir type was defined as fracture-pore  type. The reservoirs were classified in four types, and in this area reservoirs mainly belong to type Ⅲ,however, in the stratum profile, type Ⅰand type Ⅱ were few distributed, and formed 1~2 high porosity section. The reservoir physical property were primarily dominated by sedimentary facies、corrosion and  dolomization. Through reservoir prediction, it indicated that the reservoir in Mainan structure and Mopan-Laowan buried structure which located in short limb and  bottom wall were finely developed ,this two areas were the primary area for the further exploration and drill site design in Dachiganjing structural belt.
