【摘要】 随着辽河油田勘探开发的不断深入，对于辽河油区的浅中上部含油气储层的测井资料解释工作显得越来越重要，尤其是浅中上部的浅气层开发和利用。在东部地区主要呈现浅层气的分布态势，基本分布在东部桃园、大平房、荣兴屯，沈北的静35块；西部主要是稠油区块的稠油。辽河油田浅气层分布较广，但由于储层的沉积、发育等地质条件比较复杂(特别是浅部油气层，可参考的测井、地质资料较少)，用以往中深层及局部区块的解释方法已不能满足油田对浅部(井深小于1600米)的油气勘探开发需求。所以本论文主要是对桃园、大平房、荣兴屯、静35块等区块的浅层气的解释方法进行深入的研究，本论文的开展对油田浅层气的开发具有重要意义。 1、论文使用的研究方法和手段 1)、对浅气层发育较多地区，特别是部分已投入开发地区进行重点研究，分析其测井响应特征； 2)、对浅气层地质、电性特征进行研究，分析适合于浅气层的测井系列，建立气层定性解释分析图版； 3)、引入相应的数学手段，在定性分析基础上，研究建立相应的测井解释方法； 4)、编制相应的计算机解释处理程序； 5)、利用解释图版，复查挖潜部分油田的浅层气，对部分井进行精细处理解释，寻找新气层。 6)、提供研究报告、方法应用结果及相应图件、程序说明。 2、论文完成的主要内容 论文立足于辽河油田砂泥岩储集层浅层的地质特点进行了以下研究工作： 1)以部分浅层测井资料为依据，分析浅气层在测井曲线上的响应特征，研究建立了大平房等地区浅气层定性解释图版； 2)利用定性判别图版对静35块、青龙台等油田的浅气层进行了复查解释，其中对静35块进行了全面系统的复查，本次复查共初步修改结论25口井，共计77层，累计厚度222.3米，在青龙台油田也发现了一些新的浅气层； 3)在定性解释图版研究的基础上进行了相应的定量解释方法研究； 4)在方法原理研究的基础上，编制了相应的浅气层解释程序。 5)利用编制的处理程序进行了实际使用研究，效果较好。 3、取得的主要成果 1）、水次卞蛰以桃M、人个心浮地卜、以及抑35块。沈67块和占龙台汕问的浅”－－引主资料为依抓，分析研究了f戈’。气店测井D山残帅应特川－，W穴述寸了朴卜丫的定性解释闯版； 二）、以岩心资料为依抓，人州。附释间版作为参考，分训研究止立了3了OO、囚产’常地测八资料的汾乙U解释人法，M利。八沾’乙L解椎符合‘一均达到了m％以卜。3）、地过汾引／分析解科间版复丹了i35块、；丫止＜冲11川的老儿资料，发肌并修改了－儿新的汾（店。 ·股忆况卜，3700测儿资例汹过－。孔隙度资料父会。I以从小识另小－（L。1分id本次建）的附释方法对储后进订解释，’引。Z以另州1y和率史仆。小次汕‘刑《域上尘为国产“‘沼规测什系列，实际解释小巡士山仍u题山】。蛰体现介妒乓测儿资和。卜，本次研穴的重点主要集小／1：常规测井资判－力lI，并取w了较人的进爬，山：女际应川小，效果较灯，在邢分区块发现了新的气淙。更多还原

【Abstract】 With the development of exploration and exploitation in Liaohe Oil Field, logging data’s interpretation is becoming more and more important for shallow middle and upper oil and gas bearing reservior, especially shallow gas layer’s exploitation and utilization. In east area, gas of shallow layer is dominant, which is distribute mainly at the east of Taoyuan,Dapingfang,Rongxingtun,Jing35 of Shenbei. In west area, heavy oils dominant. In Liaohe Oil Field, the distribution of shallow gas layers is very extensive, but geological conditions such as reservior sendiment and development are complicated (particularly for shallow oil and gas layers, logging and geology datas which can be refered are very limited). The interpretation method for middle-lower layers and local areas can’t be used in shallow layers (well depth not more than 1600m ). So this paper mainly researchs on interpretation method of shallow gas layers for Taoyuan,Dapingfang,Rongxingtun and Jing35. It’s very important for the Oil Field.March 2001, the topic was established, under the support of some experts of the company and interpretation center, I paid close attention to the study and expected destination was achieved. Shallow gas layers logging interpretation method has been established, corresponding software has been programmed. My research has some features.1) Based on logging datas of part of shallow layers, integrated with datas of geology, and exploitation, after analysing response features on curves of shallow gas layers, qualitative interpretation chart was established for Jing35,Shen67 and Qinglongtai.2) In Jing35,Shen67 areas, shallow layer gas-was reexamined and interpreted, For Jing35, The results of 25 wells modified, the thickness of gas layer increased by 222.3m ,15 wells were modified in Qinglongtai Field, increased by 79.2m.3) On the base of the qualitative interpretation chart, quantitative interpretation method was researched, corresponding processing program was designed.4) Utilizing processing program, modifying interpretation parameters processing shallow layer datas of Taoyuan and Dapingfang areas. The result is very good.5)Integrated logging datas with geology and exploitation datas, through researching logging response of shallow gas layers, interpretation chart and method were established, which are practical and reliable.At last, I must give my thanks to professor Tang Dazhen for his instruction. Thanks to many leaders and comrades who had given me help during the research.更多还原
