摘要:
综合利用岩芯、测井资料,结合典型地区地质统计学特征,对塔河三叠系下油组河流相夹层成因类型及其分布特征进行研究。结果表明:根据成因类型下油组夹层分为单元间夹层及单元内夹层,只有单元间夹层是井间可对比的,对抑制底水锥进具有重要作用;根据夹层岩性类型及其岩电响应特征将夹层分为泥质、钙质、低渗透夹层;泥质夹层延伸较好,为主要夹层类型;下油组划分出11个延伸较稳定的夹层,但在目前井网下井间是不连续的;下油组夹层密度平均为0.14,夹层频率平均为0.07,夹层总体不发育,夹层平面分布大体呈北东、南北向分布,其宽厚比为1:80～1:100,波及宽度为200～500m。明确夹层分布特征对指导该区底水油层注水开发有着重要意义。
Abstract:
Through analyzing the cores, logging data and geological statistics, the genetic category and distribution characteristic of fluvial facies reservoir Interbed is studied. The result shows that the genetic category of interbed can be divided into inter-unit interbed and intra-unit interbed, among which only intra-unit interbed can be contrasted between wells and may have a great effect on restraining bottom water coning. On the basis of rock category and rock electrics character, interbed may be divided into muddy intercalation, calcareous intercalation and low permeable sub-layer. Muddy intercalation which forms overflow deposit extends well and is the main interbed category. Low oil formation could be divided into 11 stably extended interbeds. However, at present net well, the interbed is inconstant among wells. Most of the intra-unit interbeds are small-sized, utmost unsteadily and uncontinuous among wells. They can not shelter from water flooding and beneath water obviously. The average density of interbed is 0.14 in low oil formation with an average frequency of 0.07. It is thus clear that interbeds are undeveloped generally. The plane of interbed approximately distributes northwest and south-north. The ratio of width to thickness is about 1:80～ 1:100, and the width is approximate 200～500 m. It is meaningful that clearing the distribution characteristic of interbeds guides the injection exploitation of bottom water reservoir.
