军马站开发区位于黄骅坳陷孔店潜山构造带北端,为孔隙及裂缝发育的双重介质复杂玄武岩油藏,主力目的层沙三段玄武岩划分为爆发相和溢流相的3类玄武岩储集层,储集层岩性、物性、油藏类型及流体性质为国内少见。介绍了根据该特殊储集层特点开展岩石物理研究的思路和方法:利用测井资料成功地识别了3类玄武岩储集层;利用测井资料,结合常规及全直径岩样物性分析资料,建立了泥质含量及孔隙度解释模型;利用CT扫描成像新方法,在密闭取心和油基钻井液取心资料不多的情况下,成功地求取了含油饱和度;利用井周声波成像等测井新技术判断裂缝,结合CT扫描求取了裂缝孔隙度;建立了适用的有效厚度划分标准。在此基础上,对该区所有完钻井目的层段的测井资料进行了重新处理、解释,复查油层有效厚度,增产效果显著。图3表1参4(邹冬平摘
The Junma station development zone is located at the northern end of the Qongdian buried hill structure belt in the Huanghua Depression. It is a dual-medium complex basalt reservoir with pore and fracture development. The basalts of the Es3 in Bashang are divided into three types of basalts in the eruption phase and overflow phase Layer, reservoir lithology, physical properties, reservoir types and fluid properties are rare in China. Based on the characteristics of this special reservoir, the ideas and methods of rock physics research are introduced. Three kinds of basalt reservoirs are successfully identified by using well logging data. By using the well logging data and the physical and chemical analysis data of conventional and full-diameter rock samples, Using the new method of CT scanning imaging, the oil saturation was successfully obtained under the condition of closed coring and little coring data of oil-based drilling fluid. Using well-borehole acoustic imaging and so on Fracture was judged by new logging technology and fractured porosity was obtained by CT scanning. The applicable criteria for effective thickness division were established. On this basis, all well logging data of all the drilling completion wells in this area were reprocessed, and the effective thickness of the oil formation was reexamined and the stimulation effect was remarkable.
