【摘要】 LS地区是惠民凹陷重要的火成岩发育区之一,裂缝主导型油藏具有较大勘探潜力。由于火成岩储层的特殊性和不确定性,使得对其储集空间的横向预测和精细描述变得相当困难,成为制约火成岩油藏高效勘探开发的关键因素。针对这一问题,进行了火成岩裂缝发育带地震识别方法研究:①研究了侵入火成岩体的裂缝类型、分析了火成岩裂缝形成的控制因素;②进行了精细岩心描述、建立裂缝型储层的测井分类标准、火成岩储集层测井综合评价等综合地质研究;③提出了"侵入岩主导裂缝发育指数"方法,根据构造裂缝产生的原因,从平面上预测侵入岩不同部位发育裂缝的可能性。将研究结果应用于S741火成岩开发部署,取得了较好的效果。更多还原

【Abstract】 LS area is one of the important area where developed igneous rock in Huimin sag,it has greater exploration potential on fracture reservoir.Because of the particularity and uncertainty of the igneous rock reservoir,the horizontal prediction and fine description on the accumulation room are very difficult and are the key elements to explore and develop effectively the igneous rock reservoirs.To counter these problems,the seismic methods to recognize the igneous rock fracture development belt are researched.① Researched the fracture type of the intruded igneous rock body and the control factors of forming igneous rock fracture.②made miscellaneous geologic investigations,such as fine core description,the logging classification standards for the fracture reservoir,the integrated evaluation on the igneous rock reservoir and so on.③ developed a method called as "intruded rock dominant fracture development index",by which the capability of the fracture developed in different position of the irruptive rock could be predicted horizontally according to the reasons for developing tectoclase.A better result had been obtained after the method is applied on the development deployment for S741 igneous rock.更多还原
