井下复杂油气水层地质地球物理综合识别与评价
|
摘要
本论文主要是利用热解色谱、气相色谱等地质录井新技术评价手段，结合地质、地球化学及地球物理方法，针对轻质油层，残余油水层识别对象开展研究。
应用热解参数建立估算含油饱和度、原油粘度、密度等定量评价参数方法，对于精细勘探，提交地质储量具有重要指导意义。
准确识别油气层，提高综合解释符合率可以对井筒储层的流体性质准确识别评价，为制定合理的试油压裂设计方案提供依据，减少勘探风险，提高勘探效益，实现油水层从定性解释到定量评价的飞跃。
该项研究结合目前正在趋于成熟的其它地质录井技术，如荧光定量分析、荧光显微图像技术以及液相色谱技术等将形成一套适合不同原油性质的油水层综合识别评价方法，较大的提高综合解释符合率，把这些技术推向现场，形成综合评价录井体系，准确回答地层当中“是什么”，“有多少”，“流动性”，“产出量”几个问题，实现对储层的精细评价，满足勘探开发的需求。因此该项研究具有广阔的应用前景，能够创造出较高的经济效益和社会效益。
本论文以碎屑岩储层油水层的识别评价为研究对象，主要以岩石热解、气相色谱等新技术的开发应用为核心，一年来，共统计了95口井录井、测井、试油等项资料，并进行了现场试验，建立了综合识别评价油水层的方法，取得了以下研究成果：1、建立与完善了录井单项新技术识别油水层的方法；2、确定了产层下限值的求取方法；3、建立与完善了综合利用录井新技术识别评价油水层的方法，并形成了多种复杂油水层解释评价模式。
该项成果在大庆探区卫星-太东、新肇地区新井解释中初步应用，见到了较好效果，油水层综合解释符合率达87.7％，其中，轻质油层解释符合率达89.3％，残余油水层解释符合率达81.8％，均超过或达到预期的技术指标。
本项研究紧密结合勘探生产实际，充分发挥了地质录井新技术在油水层识别评价上的技术优势，增加了解释评价的技术手段，提高了解释评价水平，在实际生产中得到了验证，见到了较好的效果，同时，我们以储层的物性、含油性以及原油性质等参数研究为基础建立的油水层识别评价方法，其基本研究思路及解释模型不受具体区块限制，具有广泛的适用性，应用前景广阔。
New geological logging technical method of pyrolysis gas-chromatogram and Gas chromatography is briefly introduced to evaluate Light crude oil zone and Residual oil zone here, involved in Geology, GeochemicaL Pyrolytic parameter and Geophysical method.
Pyrolytic parameter is used to establish the quantity evaluative method on estimating oil saturition, Viscosity of petroleunu Density of crude oil, it is important significant to Detailed survey, oil and gas geological reserves .
It is breakthrough that the method result in detailed distinguishing and evaluating the fluid property of reservoir bed in barehole by precise distinguishing oil and gas zone. Improving comprehensive explanative percent, give reasonable plan of testing, reduce exploration risk, and jump from relative explanation to quantitive evaluation.
The research answers: l.what is in bed 2.How much is in bed 3.How is flow property 4.How much of recovery are there in bed.
Within one year, the mud-logging data. Logging data, Testing data from 95 drilling well were collected and the trial in place was run. the comprehensive method about distinguishing and evaluating on oil gas and water bed has been established . then achieve the result following:1.establishing the new mud-logging method to distinguish oil and water bed. 2.getting the calculative method on low critical value of productive bed. 3.taking hold of the new distinguishing oil and water method by using pyrolysis gas-chromatogram and Gas chromatography and establishing fewer explanative and evaluative module on complex oil and water bed.
The new technology take better effect at Wei Xing-taitong oil field, Xin zhao oil field in Daqing. Comprehensive explanative percent of oil water bed achieve 87.7%, meanwhile explanative percent of light crude oil bed is 89.3%. explanative percent of residual oil bed is 81.8%.
The research is know as important method and take better effect.
